The United States is the lane where the paperwork starts before the cargo moves. The Importer Security Filing has to be lodged with U.S. Customs and Border Protection at least 24 hours before the container is loaded in China, and the ten data elements it needs are origin facts: the manufacturer, the seller, the buyer, the ship-to party, the container stuffing location, the consolidator, the commodity codes. A late or inaccurate filing carries penalties. A forwarder that works for the factory has no reason to chase that data on your timetable.
Duty is the second thing to settle before the purchase order. Chinese-origin goods pay the normal tariff rate for their classification plus, for many products, additional tariffs under Section 301 and later actions, and the combined rate can exceed the freight. Confirming the classification, the applicable additional tariffs and the origin is part of the purchasing decision rather than the shipping one. Where the classification is genuinely arguable and the value is material, a binding ruling converts an open risk into a settled position.
Product rules follow the product. Electrical goods answer to one agency, consumer products to another, food-contact items, cosmetics and medical devices to a third, wood products to declaration requirements, and vehicles and parts to their own standards. Goods containing cotton, polysilicon or tomato products, and anything with a supply-chain link to Xinjiang, need traceability documentation to clear under forced-labour rules, and solar products are the most frequent case. Every one of these is evidence obtained from the factory.
Port choice is a geography decision. West Coast ports, Los Angeles and Long Beach, Oakland, Seattle and Tacoma, take the mainline transpacific services in around 14 to 20 days from South China and then hand the cargo to rail or truck for the rest of the continent. East Coast and Gulf ports, New York and New Jersey, Savannah, Houston, run around 28 to 38 days through the Panama Canal but land the container where eastern demand is. Air into Chicago, Los Angeles or New York is four to seven days for the urgent part of an order.
Weight is a destination problem as well as a vessel one. A container loaded to its rated payload can be over the legal road limit in the destination state, which means a heavy cargo of hardware, tiles or machinery parts is loaded to the road limit or split across two lighter boxes before it leaves China. Finding this out at the port means paying to transload.
On the China side the shipment needs the supplier's export declaration to agree with the invoice your broker will enter on, the verified gross mass declared, the pallets marked, the dangerous-goods screening done for anything with a battery, and the Importer Security Filing data delivered to your broker in time. Under FOB with your own nominated forwarder, that data is reachable. Under the factory's forwarder it usually is not until it is late.
We run the China side for US importers, from any manufacturing province to any major Chinese port or airport, and hand the entry data to your broker before the cut-off rather than after the vessel has sailed. Send us the purchase order, the destination and the delivery date, and we will come back within one business day with West Coast and East Coast options priced door to door.
