01Why does the factory price hide the true cost of sourcing in China?

The factory price is only the start. Freight, duties, customs brokerage, inspection and payment fees can add a large share on top - and tariff rules keep changing.

Buyers who price on ex-works alone discover their margin at the port. Add an unvetted supplier or an order placed outside Trade Assurance, and one bad shipment can wipe out a quarter's profit.

02How an AI agent audits import risk and landed cost

Calculate the landed cost to the US for 500 portable blenders at $5.10 EXW Shenzhen, sea freight LCL. Include freight, insurance, current US duty for the HS code, customs brokerage and payment fees. Then run a risk audit on the supplier: Trade Assurance coverage, dispute history, certificate validity. Save both to a spreadsheet.

The agent looks up the likely HS code, current duty context and freight estimates, and builds a line-by-line landed cost per unit - so you price with real margins.

In parallel it audits the supplier: Trade Assurance eligibility, years active, response and dispute signals, certificate validity. Everything lands in one file you can share with your partner or accountant.

044 rules for safe B2B importing from China

1. 1

   Price on landed cost, never EXW

   Build margin on the full per-unit cost. Use the calculator below to see how each layer moves the number.

2. 2

   Pay inside Trade Assurance

   Keep order terms, specs and inspection requirements inside the protected order - never switch to off-platform payment on request.

3. 3

   Recheck duties on every order

   Tariff rates change. Ask the agent to confirm the HS code and current rate before you commit to a price.

4. 4

   Book a pre-shipment inspection

   For first orders, a third-party inspection costs little compared to a rejected batch.
