Buying Valves and Pipe Fittings from China: A Complete Guide for International Buyers
China is one of the world's largest manufacturing bases for industrial valves, pipe fittings and piping components. International buyers can source everything from standard ball valves and gate valves to industrial butterfly valves, check valves, control valves, stainless steel pipe fittings, flanges, elbows, tees, reducers and highly customized components.
For companies involved in construction, plumbing, water treatment, oil and gas, chemical processing, manufacturing, fire protection, agriculture, HVAC, mining and industrial projects, Chinese manufacturers can offer a broad selection of products in different materials, pressure ratings, sizes and international standards.
However, buying valves and pipe fittings from China is not simply a matter of finding a supplier with the lowest price.
The valve or fitting must be compatible with the fluid, pressure, temperature, pipe system, connection standard and intended application. A component that looks correct in a product photograph can still be technically unsuitable for the installation.
International buyers must therefore consider technical specifications, material quality, manufacturing standards, testing, certifications, supplier capabilities, packaging, customs requirements and transportation costs.
This guide explains how to source valves and pipe fittings from China, how to identify suitable Chinese manufacturers, what specifications to provide, how to compare suppliers, what quality-control checks to perform, and how to arrange international shipping.

What Types of Valves Can You Buy from China?
The term "industrial valve" covers many different products.
Choosing the right type depends on what the valve needs to do.
Ball Valves
Ball valves use a rotating ball with a passage through it to control fluid flow.
They are widely used for:
• Water
• Air
• Gas
• Oil
• Chemical applications
• Industrial processing
• Plumbing
Common configurations include:
• 2-way ball valves

Globe Valves
Globe valves are commonly used where flow regulation or throttling is required.
They may be used in:
• Steam systems
• Water systems
• Process pipelines
• Chemical systems
• Industrial plants
The pressure drop through a globe valve can be greater than through some other valve designs, so the application should be considered carefully.

Butterfly Valves
Butterfly valves use a rotating disc to regulate or isolate flow.
They are popular for larger-diameter pipelines because they can be relatively compact and lightweight compared with some other valve designs.
Common configurations include:
• Wafer butterfly valves
• Lug butterfly valves
• Flanged butterfly valves
• Pneumatic butterfly valves
• Electric butterfly valves
• Manual butterfly valves
They are commonly used in:
• Water treatment
• HVAC
• Fire protection

• Chemical systems
• Irrigation

Check Valves
Check valves allow flow primarily in one direction.
Common types include:
• Swing check valves
• Wafer check valves
• Lift check valves
• Dual-plate check valves
• Spring check valves
• Foot valves
When selecting a check valve, consider flow direction, pressure, installation orientation, closing characteristics and the possibility of water hammer.

Needle Valves
Needle valves are designed for precise flow control, particularly where relatively small flow adjustments are required.
They may be used in:
• Instrumentation
• Hydraulic systems
• Gas systems
• Laboratory equipment
• Process control

Control Valves
Control valves are more sophisticated than basic isolation valves.
They are used to automatically regulate parameters such as:

A control-valve purchase may require additional information regarding:
• Control signal
• Actuator
• Fail position
• Valve characteristic
• Flow coefficient
• Pressure differential
• Fluid properties
• Instrumentation
For complex industrial applications, buyers should provide the manufacturer with complete process data rather than choosing a control valve from a generic online catalog.

Safety and Relief Valves
Safety and pressure-relief valves are used to protect systems from excessive pressure.
These products can be subject to specific regulatory and engineering requirements.
For critical pressure applications, buyers should confirm the exact applicable standard, certification and testing requirements before ordering.

The correct tee depends on the pipe size, connection type, material and pressure requirements.

Pipe Reducers
Reducers connect pipes with different diameters.
The two major types are:
• Concentric reducers
• Eccentric reducers
The appropriate type depends on the piping layout and application.

Flanges
Flanges provide a detachable connection between piping components.
Common flange types include:
• Slip-on flanges
• Weld-neck flanges
• Blind flanges
• Socket-weld flanges
• Threaded flanges
• Lap-joint flanges
Flange selection must consider more than nominal pipe size.
Buyers should specify:
• Nominal size
• Pressure class
• Material
• Facing
• Bolt-hole pattern
• Outside diameter
• Bore
• Thickness
• Applicable standard

Threaded Pipe Fittings
Threaded fittings are common in smaller piping systems and plumbing applications.
However, thread standards vary internationally.
This is one of the most important details to clarify when importing fittings from China.
Common thread systems include:
• NPT
• BSP
• BSPT
• BSPP
• Metric threads
NPT and BSP are not interchangeable.
A fitting can have the correct nominal size but still be incompatible because the thread standard is different.

Stainless Steel Pipe Fittings from China
Stainless steel fittings are widely used because of their corrosion resistance.
Common grades include:
• 304 stainless steel
• 316 stainless steel
• 316L stainless steel
• Duplex stainless steel
• Other specialized alloys
Do not assume that "stainless steel" automatically means 316.
The material grade should be explicitly stated on the purchase order and, where necessary, verified through material certification or testing.
For corrosive environments, chemical compatibility and temperature should also be considered.

Carbon Steel Pipe Fittings
Carbon steel fittings are widely used in industrial piping systems.
They can be manufactured as:
• Butt-weld fittings
• Forged fittings
• Threaded fittings
• Flanges
• Other configurations
For carbon steel fittings, buyers should specify the required material grade and applicable manufacturing standard.

Ductile Iron Pipe Fittings
Ductile iron is commonly used in water and municipal infrastructure.
Products may include:
• Flanged fittings
• Tees
• Bends
• Reducers
• Couplings
Buyers should pay attention to:
• Coating
• Internal lining
• Pressure rating
• Dimensions
• Joint type
• Applicable water-piping standards

How to Choose the Right Valve or Pipe Fitting
The correct product depends on several variables.
1. Pipe Size
Specify the actual required pipe size and standard.
For example:
• DN25
• DN50
• DN100
• 1 inch
• 2 inch
• 4 inch
Do not assume that DN and inch sizes can simply be converted without considering the applicable standard.
2. Pressure Rating
Pressure rating may be expressed using different systems.
Depending on the product and standard, you may encounter:
• PN10
• PN16
• PN25
• Class 150
• Class 300
• Class 600
• Working pressure in bar
• Working pressure in MPa
These designations should not be treated as interchangeable without checking the relevant standard.
3. Temperature
Temperature affects:
• Valve body material
• Seals
• Seats
• Gaskets
• Lubricants
• Pressure capability
Always provide the expected operating temperature and maximum temperature.
4. Fluid
The supplier should know exactly what will flow through the system.
Examples include:
• Water
• Drinking water
• Seawater
• Steam
• Compressed air
• Natural gas
• Oil
• Fuel
• Hydraulic fluid
• Chemicals
• Wastewater
• Slurry
A valve suitable for water may not be suitable for a particular chemical or gas.
5. Corrosion Requirements
For corrosive fluids or environments, material selection becomes particularly important.
Consider:
• Fluid chemistry
• Concentration
• Temperature
• Chloride exposure
• External environment
• Required service life
6. Connection Type
Specify whether you require:
• Threaded

Valve Standards and Pipe-Fitting Standards
Standards are one of the most important areas to clarify when buying valves and fittings from China.
Different markets and industries may use different standards.
Depending on the application, you may encounter standards from organizations such as:
• ASME
• API
• ASTM
• ISO
• DIN
• EN
• JIS
• GB/T
The specific standard matters.
For example, a valve manufactured to one dimensional or pressure standard may not be directly interchangeable with one manufactured to another.
When requesting quotations, specify the exact standard required rather than simply asking for an "international standard" valve.

Why Valve Dimensions Matter
Two valves can both be described as "DN100" while having different:
• Face-to-face dimensions
• Flange dimensions
• Bolt-hole patterns
• Bore sizes
• Pressure ratings
• End connections
This can create installation problems.
For replacement components, provide the supplier with:
• Existing valve model
• Manufacturer
• Dimensions
• Drawings
• Photographs
• Nameplate information
Where possible, provide the actual technical drawing.

How to Find Valve and Pipe Fitting Manufacturers in China
International buyers can find Chinese suppliers through several channels.
Alibaba
Alibaba has a large selection of Chinese manufacturers and suppliers selling industrial valves and pipe fittings.
It can be useful for initial supplier discovery and quotation requests.
However, an online listing should not be treated as proof that a supplier is capable of manufacturing the exact product required.
Made-in-China
Made-in-China is another B2B marketplace where international buyers can discover Chinese industrial equipment manufacturers and exporters.
Global Trade Shows
Industrial trade shows can be useful for finding established manufacturers of:
• Valves
• Pumps
• Pipes
• Fittings
• Industrial equipment
Meeting suppliers in person can make it easier to discuss technical requirements and factory capabilities.
Direct Factory Research
Search for manufacturers based on the specific product.
Instead of searching only for:
"China valve supplier"
consider searches such as:
• China stainless steel ball valve manufacturer
• China API gate valve manufacturer
• China industrial butterfly valve factory
• China forged steel valve manufacturer
• China stainless steel pipe fitting manufacturer
• China butt weld fitting manufacturer
• China ductile iron pipe fitting factory
More specific searches can help identify suppliers that specialize in the relevant product.

How to Verify a Chinese Valve Manufacturer
Before placing a significant order, investigate the supplier.
Check the Legal Company Name
Confirm:
• Registered company name
• Business scope
• Registered address
• Manufacturing location
• Export experience
The company receiving payment should be clearly connected to the supplier you have evaluated.
Determine Whether It Is a Factory
Ask for:
• Factory address
• Factory photographs
• Production-line photographs
• Machinery information
• Testing equipment
• Factory video
• Audit reports where available
A trading company may still be useful, but you should know who is actually manufacturing the product.
Check Production Equipment
For valves and fittings, manufacturing capability may involve:
• Casting
• Forging
• CNC machining
• Welding
• Grinding
• Assembly
• Pressure testing
• Surface treatment
• Coating
• Packaging
A supplier's equipment should be consistent with the products it claims to manufacture.

Quality Control When Buying Valves from China
Quality control is particularly important for valves because defects can cause leakage, installation failures or operational problems.
Depending on the product, inspection can include:
Visual Inspection
Check:
• Body condition
• Casting quality
• Machining
• Paint/coating
• Markings
• Nameplates
• Corrosion
• Threads
• Flanges
Dimensional Inspection
Verify:
• Face-to-face length
• Overall dimensions
• Flange dimensions
• Bolt-hole pattern
• Bore
• Thread dimensions
• Wall thickness
Material Verification
For critical applications, verify the specified material.
Documentation may include:
• Material certificates
• Mill test certificates
• Heat numbers
• Chemical composition
• Mechanical test results
For higher-risk applications, independent material verification may also be appropriate.

Pressure Testing Valves Before Shipment
Pressure testing is one of the most important quality-control procedures for industrial valves.
Depending on the valve and applicable standard, testing may include:
• Shell testing
• Seat testing
• Leakage testing
• Hydrostatic testing
• Pneumatic testing
The buyer should specify the required testing standard and acceptance criteria before production.
Do not simply ask a supplier whether the valve is "tested."
Ask:
What test was performed, according to which standard, at what pressure, for how long, and what was the acceptance criterion?
This produces a much more useful quality-control record.

Valve Leakage Testing
For isolation valves, leakage performance can be particularly important.
Depending on the applicable specification, buyers may encounter leakage classifications and test standards such as API or ISO requirements.
The exact acceptance level should be established in the purchase specification.
For critical industrial applications, the testing requirements should not be left to an informal supplier promise.

Pipe Fitting Quality Inspection
Pipe fittings can be inspected for:
• Dimensions
• Wall thickness
• Material
• Surface condition
• Weld quality
• Thread quality
• Ovality
• Bevel dimensions
• Radius
• Markings
• Coating
For welded fittings, additional inspection may be required depending on the application.
Potential methods include:

• Ultrasonic testing
• Radiographic testing
• Magnetic-particle testing
• Dye-penetrant testing
The appropriate method depends on the fitting, material and engineering requirements.

Material Certificates for Chinese Valves and Fittings
For industrial projects, request material documentation where appropriate.
A material certificate can provide information such as:
• Material grade
• Heat number
• Chemical composition
• Mechanical properties
• Manufacturer
• Production batch
The certificate should correspond to the actual material supplied.
For critical projects, traceability can be an important procurement requirement.

Ask for a Valve and Fitting Datasheet
Before ordering, ask the supplier for a technical datasheet.
A valve datasheet might contain:
• Valve type
• Size
• Pressure rating
• Body material
• Trim material
• Seat material
• Stem material
• Connection type
• Temperature rating
• Flow direction
• Actuator
• Applicable standards
A pipe-fitting datasheet should similarly specify:
• Size
• Material
• Schedule/wall thickness
• Connection
• Standard
• Dimensions
• Pressure requirements
• Surface treatment

How to Request Quotations from Chinese Suppliers
A detailed RFQ makes supplier comparisons much easier.
For example:
Product: Stainless steel ball valve
Size: DN50
Pressure: PN16
Body: Stainless steel 316
Ball: Stainless steel 316
Seat: PTFE
Connection: Flanged
Standard: [Required standard]
Quantity: 100 pcs
Fluid: Water
Operating temperature: 5–80°C
Actuation: Manual
Required documents: Datasheet, material certificate, pressure-test report
Destination: [Country/city]
Then ask every supplier to quote against the same specification.

Compare Chinese Valve Suppliers on an Equal Basis
A useful supplier comparison should include:
Specification Supplier A Supplier B Supplier C
Valve type
Size
Pressure rating
Body material
Trim material
Seat material
End connection
Standard
Actuator
Testing
Certification
Warranty
Unit price
Packaging
Freight
Landed cost
This helps prevent a supplier from appearing cheaper simply because its quotation excludes important components.

What Should Be Included in a Valve Quotation?
Ask the supplier to clarify whether the quoted price includes:
• Valve body
• Trim
• Seat
• Stem
• Handle
• Actuator
• Mounting bracket
• Positioner
• Solenoid
• Limit switch
• Gaskets
• Bolts
• Flanges
• Testing
• Certification
• Packaging
• Spare parts
For automated valves, these differences can have a substantial effect on the final cost.

OEM Valves from China
Chinese manufacturers can produce valves according to buyer drawings and specifications.
OEM projects may involve:
• Custom dimensions
• Custom materials
• Private labeling
• Custom packaging
• Customer-specific markings
• Special coatings
• Modified actuators

How Much Do Valves and Pipe Fittings from China Cost?
There is no universal "China price" for valves and fittings.
The price depends on:
• Valve type
• Size
• Material
• Pressure class
• Standard
• Quantity
• Actuation
• Brand
• Certification
• Testing
• Customization
• Packaging
A small brass ball valve can cost dramatically less than a large stainless steel industrial control valve.
Likewise, a standard carbon-steel elbow and a specialized alloy-steel fitting can have completely different manufacturing costs.
Therefore, price comparisons are meaningful only when the technical specifications are equivalent.

Shipping Valves and Pipe Fittings from China
Valves and fittings are generally well suited to ocean freight when purchased in commercial quantities.
They can also be transported by:
• Air freight
• Express courier
• Rail
• Truck
• Sea freight
The appropriate method depends on:
• Weight
• Volume
• Urgency
• Quantity
• Destination
• Product value
Because metal valves and fittings can be dense and heavy, shipping costs should be calculated using accurate packed dimensions and gross weight.

Packaging Industrial Valves for International Shipping
Good packaging protects the products from:
• Impact
• Moisture
• Corrosion
• Scratches
• Contamination
• Deformation
Depending on the shipment, packaging may include:
• Cartons
• Pallets
• Wooden cases
• Export-grade crates
• Plastic bags
• Protective caps
• Flange covers
• Moisture barriers
• Rust-prevention materials
For stainless steel and precision-machined products, protection against scratching and contamination can be particularly important.

Consolidating Valves and Fittings from Multiple Chinese Suppliers
International buyers often purchase piping components from several factories.
For example:
Supplier A: Ball valves
Supplier B: Butterfly valves
Supplier C: Stainless steel elbows
Supplier D: Flanges
Supplier E: Pipe tees
Supplier F: Actuators
Instead of arranging separate international shipments, the goods can be sent to a China warehouse.
The warehouse can:
1. Receive each supplier's shipment
2. Record the cargo
3. Check packages
4. Store the products
5. Consolidate the orders
6. Repack or palletize if necessary
7. Measure the consolidated cargo
8. Arrange international transportation
This can simplify logistics and potentially reduce the cost of shipping multiple smaller orders separately.

Shipping Valves and Pipe Fittings Door to Door
A freight forwarder can arrange a door-to-door shipment from China to the buyer's destination.
A typical process may look like:
Chinese factories → China warehouse → export customs → international freight → destination customs → final delivery
For commercial or industrial cargo, confirm whether the quotation includes:
• China pickup
• Export customs clearance
• International freight
• Import customs clearance
• Import duties
• VAT/GST
• Destination handling
• Final delivery
If the cargo is heavy or palletized, also verify:
• Forklift requirements
• Liftgate requirements
• Truck access
• Appointment delivery
• Residential delivery restrictions
• Remote-area fees

DDP vs DAP for Valves and Fittings
The shipping arrangement can significantly affect the buyer's responsibilities.
DDP
A DDP service can incorporate import customs clearance, applicable duties/taxes and final delivery into the logistics arrangement, depending on the provider's exact terms.
This can simplify the process for buyers who do not have their own customs infrastructure.
DAP
With DAP, the buyer generally remains responsible for import duties and taxes.
Always confirm the exact scope of the service rather than relying solely on the words "door-to-door."

Customs and HS Codes for Valves and Pipe Fittings
Valves are commonly classified under HS heading 8481, which covers taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like.
Pipe fittings can fall under different HS classifications depending on the product, material and construction.
The correct classification can depend on whether the product is:
• A valve
• A fitting
• A flange
• A threaded fitting
• A plastic fitting
• A steel fitting
• A specialized industrial component
Buyers should verify the applicable tariff classification for their destination country before importing.
The HS code can affect:
• Import duty
• VAT/GST
• Customs declarations
• Regulatory requirements
• Import documentation
Do not assume that every valve or fitting uses one universal tariff code.

Calculate the Landed Cost Before Ordering
Suppose you purchase:
Valves: $4,000
Pipe fittings: $2,000
China domestic transport: $250
Export/handling: $150
International freight: $700
Insurance: $50
Import duty: $350
Customs clearance: $200
Final delivery: $300
The factory invoice may be $6,000, but the actual landed cost is significantly higher.
This is why international buyers should compare:
Total landed cost per valve/fitting
rather than simply:
Factory price per valve/fitting.

Common Mistakes When Buying Valves and Pipe Fittings from China
1. Buying Based on a Product Photograph
A photograph cannot tell you:
• Pressure rating
• Material grade
• Thread standard
• Seat material
• Internal dimensions
• Testing requirements
Always work from a specification.
2. Confusing NPT and BSP
This is a common sourcing problem.
The nominal size may appear correct while the threads are incompatible.
3. Ignoring Pressure Rating
A valve must be suitable for the actual system pressure and temperature.
4. Assuming Stainless Steel Means 316
Specify the actual grade.
5. Not Confirming the Standard
"International standard" is too vague for many industrial applications.
Specify the exact applicable standard.
6. Not Checking Dimensions
The valve may technically work but still fail to fit the existing pipeline.
7. Choosing the Lowest Price
Different suppliers may quote different materials, components, standards and testing requirements.
8. Skipping Pressure Testing
For many industrial valves, testing is a critical part of quality assurance.
9. Not Requesting Material Certificates
For critical applications, material traceability can be important.
10. Forgetting Spare Parts
Consider purchasing replacement seals, seats, gaskets and other critical parts with the original order.
11. Underestimating Shipping Weight
Metal products can be extremely dense.
Accurate gross weight is essential for freight planning.
12. Assuming All Chinese Suppliers Are the Same
The Chinese valve and fitting industry includes manufacturers with very different capabilities, quality systems and areas of specialization.

How to Reduce the Cost of Buying Valves and Fittings from China
Cost reduction should not mean simply choosing a lower-quality component.
Instead, look for efficiency throughout the purchasing process.
Compare multiple manufacturers
Request quotations from several technically suitable suppliers.
Standardize specifications
Using standardized valves and fittings where appropriate can increase purchasing efficiency.
Consolidate orders
Combining multiple supplier shipments can reduce international transportation costs.
Purchase critical spare parts together
This can reduce future international freight costs.
Optimize packaging
Ask the factory to design packaging that protects the cargo without unnecessarily increasing shipping volume.
Negotiate based on quantity
Larger orders may provide opportunities for better unit pricing.
Compare landed cost
A lower factory price does not necessarily result in a lower final cost.

Final Thoughts on Buying Valves and Pipe Fittings from China
China offers international buyers a large and diverse manufacturing base for industrial valves and pipe fittings.
The opportunity is not limited to inexpensive standard products. Buyers can source highly customized components, OEM products and valves manufactured to specific engineering requirements.
But successful procurement depends on technical precision.
Before requesting a quotation, determine:
What fluid will the component handle?
What pressure and temperature will it experience?
What size and connection does the piping system require?
What material is appropriate?
What standard must the product comply with?
What testing and certification are required?
Once those questions have been answered, suppliers can be compared much more effectively.
The purchasing process should then move from supplier discovery → technical comparison → factory verification → quality inspection → packaging → international shipping → customs clearance → final delivery.
For companies buying valves and fittings from multiple manufacturers in China, consolidating the cargo through a China warehouse can further simplify procurement and international logistics.
The most important principle is:
Do not buy valves or pipe fittings based on price or appearance alone. Buy according to the application, specification, applicable standards, verified quality and total landed cost.
A properly managed sourcing process can help international buyers access China's extensive valve and pipe-fitting manufacturing base while reducing the risk of incompatible components, quality problems, unexpected shipping expenses and customs issues.

Frequently Asked Questions About Buying Valves and Pipe Fittings from China
Is China a good source for industrial valves and pipe fittings?
China has a large manufacturing base producing many types of industrial valves and pipe fittings. However, supplier capabilities vary, so buyers should evaluate manufacturers based on the specific product, application, standards and quality requirements.
How do I find reliable valve manufacturers in China?
Search B2B marketplaces, manufacturer directories, trade shows and direct factory websites. Then verify the supplier's factory, manufacturing capability, certifications, testing facilities and export experience.
Can I buy custom valves from China?
Yes. Many Chinese manufacturers offer OEM and customized valve production. Customization can include materials, dimensions, connections, actuators, coatings, markings and packaging.
What are the most common industrial valves?
Common types include ball valves, gate valves, globe valves, butterfly valves, check valves, needle valves, control valves and safety/relief valves.
What are the most common pipe fittings?
Common fittings include elbows, tees, reducers, couplings, unions, flanges, caps, plugs, adapters, nipples and other threaded, forged and welded fittings.
What is the difference between NPT and BSP?
NPT and BSP are different thread systems. A fitting designed for one is not automatically compatible with the other. Always specify the exact thread standard required.
What materials are available from Chinese valve manufacturers?
Depending on the supplier, common materials include carbon steel, stainless steel, cast iron, ductile iron, brass, bronze, duplex stainless steel, alloy steel and various plastics.
Should I buy stainless steel 304 or 316 valves?
The appropriate material depends on the fluid, temperature, corrosion environment and application requirements. Do not select a material based solely on general assumptions about which grade is "better."
What certifications should Chinese valves have?
The required certification depends on the destination market and application. Buyers should identify the applicable regulatory and engineering standards before placing an order and verify that certificates cover the actual products supplied.
How do I know if a Chinese valve is good quality?
Review the supplier's manufacturing capability, technical documentation, material traceability, pressure testing, dimensional accuracy, certifications and inspection records. For significant orders, consider independent pre-shipment inspection.
How should industrial valves be shipped from China?
Small quantities may be suitable for air freight or courier services. Larger commercial orders are often shipped by sea. The best option depends on cargo weight, volume, urgency and destination.
Can I consolidate valves and fittings from different Chinese factories?
Yes. A China warehouse can receive products from multiple suppliers, store them and consolidate them into a single international shipment.
What HS code do valves use?
Many valves are classified under HS heading 8481, but the precise tariff classification depends on the product and destination country. Confirm the applicable tariff code before importing.
How can I reduce the cost of importing valves from China?
Compare equivalent technical specifications, source from suitable manufacturers, consolidate shipments, optimize packaging, negotiate based on order quantity and calculate total landed cost rather than comparing factory prices alone.
What information should I send a Chinese valve supplier?
At minimum, provide valve type, size, pressure rating, fluid, temperature, material, connection type, applicable standard, actuation requirements and quantity. For specialized applications, provide detailed process conditions and drawings.
Can Chinese factories manufacture pipe fittings according to my drawings?
Many manufacturers can produce customized fittings according to technical drawings, dimensions and material specifications. For custom orders, approve the drawing and material requirements before production.
