China is the United States' largest supplier of goods imports. The trade between China and USA is huge. It is big metter in terms of shipping.
Now there are many shipping ways from China to the USA, from traditional to ports and modern shipping door to door solutions.
Especially there are many different sea door to door options.
-Modern air and sea freight: door to door with duty paid, can ship to all addresses in 48 continents(excluding mailbox BOX, military address, zip code: 006-009 PUERTO RICO AND VIRGIN LSLANDS Puerto Rico, Virgin Islands, 966-969 HAWAIIAND GUAM Hawaii, Guam 995-999 ALASKA Alaska, etc.) All addresses(with service) can be sent by UPS Ground(partially sent by FEDEX) but some hot Amazon fulfilment centers can be delivered by truck directly.
Air door to door takes 10-18 days to deliver while there are many options(different shipper like Matson, Zim, Cosco) for sea door to door, the quickest by Matson is around 20-25 days. If there is inspection in customs, delivery will be delayed.
There are some situations where products are suggested to ship by air. High-value cargo and time demanding cargo.
And to Amazon, walmart and other e-commerce warehouses, door to door with duty paid solutions are recommended.
It is largely decided by the billable weight for air shipping. Billable weight is a pricing technique used by carriers to calculate shipping rates per package, taking into account both dimensional weight (the length, width, and height of a package) and the actual weight of the shipment.
Express Air domensional weight(volumetric weight)=Length(CM)*Width(CM)*Length(CM)/5000
Air Freight(door to door or port to port) domensional weight(volumetric weight)=Length(CM)*Width(CM)*Length(CM)/6000.
Sea Freight(door to door)domensional weight(volumetric weight)=Length(CM)*Width(CM)*Length(CM)/6000.
Sea Freight(port to port) is billable on CBM(Cubic Meter but for too heavy product, if a CBM actual weight is over 300KG or 500KG(defined by destination port), will charge based on actual weight.
