If it is produced in Hefei, it must be inspected in Hefei, but it must be exported from other places. It is more likely to export from Shanghai Port.

The commodity inspection bureau basically doesn't care which trademark the manufacturer uses. At the same time, it does not rule out that manufacturers will export products without trademarks and then brand them in Taiwan Province Province, so it may not be feasible to report them to the customs for inspection.

I think this still needs a lawyer and legal channels.
