About these rates

The rates are those printed in the 2026 HTS Revision 23, published by the U.S. International Trade Commission. A 10-digit statistical line takes the rates printed on the 8-digit line above it. Chapter 99 duties (Section 232, Section 301, IEEPA) depend on the product, the origin and the date, are charged on top, and are not included. A code here is a strong lead, not a ruling: confirm it with a customs broker or a CBP binding ruling.
