Example
Stopped. The beneficiary is not the company on the invoice. Ask why in writing before a cent is sent.
Built on the official files: EPA TSCA inventory, AICIS inventory, USITC tariff schedule, CBP fee tables, Trade.gov AD/CVD cases, DFAT sanctions list, DHS UFLPA entity list and China company registries.
And how one check before the wire keeps it where it belongs. Watch it in English or in Chinese.
A proforma invoice like the ones in your inbox every week, with the names changed. Scroll, and watch what Sourzi would stamp.
Stamp 1 of 4 · CHECK
Every Chinese company has an 18 character credit code on its business licence. Sourzi checks the code and opens the registry record, which shows whether the seller makes citric acid or only trades it.
Stamp 2 of 4 · CHECK
Anti dumping cases A-570-937 and C-570-938 are on file for this product heading, and the rate depends on which factory made the goods, so the right factory matters as much as the right price.
Stamp 3 of 4 · STOP
The seller is a Shandong factory but the bank account belongs to a Hong Kong trading company. It is the warning sign buyers describe most often after losing a deposit.
Stamp 4 of 4 · ASK
A certificate of analysis written by the factory is a claim, not a test. Ask for an independent lab report on the actual batch before the balance is paid.

What should I check before buying citric acid from China?
Citric acid (CAS 77-92-9) is on the TSCA inventory1. The general duty on 2918.14.00.00 is 6%2, with extra tariffs on goods of China on top. Cases A-570-937 and C-570-938 cover this heading3, so ask which factory made it.
