Largest global supplier of supplement ingredients. Subject to 2018-19 Section 301 tariffs on most supplement lines, by HTS line rather than by category: vitamins (2936) and CoQ10 (2914.62.00) are not on those lists, but many amino acids and mineral salts are (glycine 2922.49.43 and magnesium sulfate 2833.21.00 carry +25%), and raw tea, spices and extracts carry +7.5%. PLUS the forced-labor Section 301 duties: an additional 12.5% on covered lines for entries on or after Jul 24, 2026. Vitamins (2936), many mineral salts and raw tea/spice forms are exempt from that newer layer as entered under the action's Note 52(b), which does not remove any older duty; amino acids, CoQ10, extracts and finished preparations are covered for supplement use. IEEPA tariffs struck down Feb 2026; the temporary Section 122 surcharge (10%) applied additionally for non-exempt categories on entries Feb 24 through Jul 23, 2026 and terminated by operation of law at 12:01 a.m. EDT Jul 24, 2026.
The forced-labor Section 301 duties effective July 24, 2026 (final action: 12.5% China, 10% India, 10% net-of-MFN EU) apply to entries on or after 12:01 a.m. ET July 24, 2026. Goods loaded and in transit before that instant and entered before July 28, 2026 are excepted and owe the lower pre-action rates. Exemptions are per HTS line under the action's Annex II: vitamins (2936) and raw tea/spice forms are exempt as entered, while amino acids, CoQ10, botanical extracts, and finished preparations are covered for supplement use — confirm your line at hts.usitc.gov or with a licensed customs broker.
