China no longer has a de minimis trade exemption. What is it?

A trade loophole called de minimis helped drive explosive growth for bargain sites such as Temu and Shein, allowing them to ship cheap goods from China to U.S. consumers without having to pay taxes and import duties.

But that now stands to change, after President Trump signed an executive order stating de minimis treatment “shall not be available” for products made in China, the top source of goods imported to the U.S.

The effects could be far-reaching: De minimis shipments account for most of the cargo entering the U.S., Customs and Border Protection said last fall. The agency said it was handling some 4 million de minimis shipments every day — a rate that would blow past the previous year’s mark of more than 1 billion shipments.
