1. Special products
Such as glasses, cosmetic instruments, and medical appliance. Amazon's fba freight from China to the United States. If these products are imported from the United States, they need to provide relative documents. If these documents are not provided, they must not be imported.
2. Anti-dumping products
These products are reflected in the commercial invoice. 80% of Amazon entering the United States from China will be stuck in customs. If it's FBA cargo, America will die if it doesn't have friends to handle this cargo for you.

3. Tariffs
I believe some Amazon FBA veterans, 90% did not pay customs duties. Amazon's fba shipment from China to the United States is personalized, which reduces the risk of FBA inventory backlog caused by slow sales: the products stored in FBA warehouse are related to account numbers, and the same products cannot be sold in multiple accounts. It is very likely that the same products will be sold out in some FBA warehouses, but not in other warehouses at the same time.
