This depends on whether the goods are shipped by air courier or air freight/cargo. Air courier shipping from China to the US (via companies like DHL, FedEx, UPS, TNT or SF Express) typically take just 3–4 business days. Air freight/cargo shipments however can take anywhere between 7–14 days depending on the specific mode used and whether the goods are only shipped to port (the airport) or all the way to door.
If you’re looking to ship in bulk from China to the US via air or sea, CNXtrans offers bulk air and sea freight shipping routes specially meant for bulk/large shipments that come inclusive of customs clearance, customs duties and delivery all the way to your doorstep (or even Amazon warehouses in the US if required). For the air freight routes, goods are first shipped to the US by commercial airlines and once the goods have arrived in the US, UPS takes over the goods and handles the delivery to door.
The best thing about shipping via air or sea freight in bulk from China to the US via CNXtrans is that it is offered on a DDP basis - meaning inclusive of customs clearance, customs duties and delivery to door. Most freight forwarders in China which ship to the US via air freight can only do so by shipping to an airport are not able to do so on a DDP basis - meaning you would have to look for a local customs broker to help clear customs for you and handle the delivery to door. With CNXtrans however, all these are taken care of for you - whether you ship in bulk by air courier, air freight or sea freight from China to the US, CNXtrans will handle the entire shipment on a door-to-door basis.
