# StoreCalc (店有数)

> Free calculators for cross-border sellers. The first tool covers US import duties on apparel. Every number is generated from the official USITC Harmonized Tariff Schedule (2026 Revision 21) and cites its source. Updated 2026-10-22.

Key facts (as of 2026-10-22):
- Apparel from China pays three stacked duties: the HTS general rate, the Section 301 China tariff (+7.5% for codes on List 4A, 9903.88.15, which covers most apparel and home textiles; +25% for List 3, 9903.88.03, which covers hats and textile bags; none for codes only on the suspended List 4B) and the Section 301 forced-labor tariff (+12.5% for China, 9903.05.31, from 2026-07-24).
- Example: a cotton knit T-shirt from China (HTS 6109.10.00) pays 36.5%; a synthetic one (6109.90.10) pays 52%.
- IEEPA tariffs are no longer collected (Supreme Court, 2026-02-20). The Section 122 10% tariff expired 2026-07-24.
