Tariff data last updated: July 24, 2026
Largest global supplier of supplement ingredients. Subject to 2018-19 Section 301 tariffs on most categories (basic vitamins/minerals excluded from that layer), PLUS the forced-labor Section 301 duties: an additional 12.5% on covered lines for entries on or after Jul 24, 2026, applied date-gated by the tools — vitamins (2936) and raw tea/spice forms are exempt as entered under the action's Note 52(b), while amino acids, CoQ10, extracts, and finished preparations are covered. 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.
Basic nutritional compounds are exempted from the 2018-19 Section 301 China lists (standard MFN base duty 0-5% for that layer). The Jul 24, 2026 forced-labor Section 301 action SPLITS this category: vitamins (2936) and many mineral salts are exempt as entered under its Note 52(b), while amino acids (2922), CoQ10 (2914.62.00), and glutathione (2930) are covered for supplement use (their chemical exemptions are pharmaceutical-use-only), and EPA/DHA (1504, unlisted) is covered outright, at an additional 10-12.5% by origin.

EXEMPTED from the 2018-19 Section 301 China lists; standard MFN base duty (0-5%) applies for that layer. Also exempt from the Section 122 surcharge throughout its Feb 24 – Jul 23, 2026 entry window (vitamins, amino acids, CoQ10 listed in Annex II; the surcharge itself terminates by operation of law at 12:01 a.m. EDT Jul 24, 2026). Forced-labor Section 301 layer (entries on or after 12:01 a.m. ET Jul 24, 2026) — SPLIT coverage verified against the action's Annex II / U.S. Note 52 tables: vitamins (2936.21.00-2936.90.01) and many mineral salts (2833/2836 lines) are exempt AS ENTERED under Note 52(b), so their total stays at the 0-5% MFN base; amino acids (2922), CoQ10 (2914.62.00), glutathione (2930), and EPA/DHA (1504, unlisted) are NOT exempt for supplement use — Note 52(e) covers the listed chemicals only for pharmaceutical applications — and carry an additional 12.5% (up to ~17.5% total). The tools display the combined 0-17.5% band with this split. In-transit exception per the DATES section (entered before Jul 28, 2026). [Split verified 2026-07-24 directly against the pre-publication final-action FRN annex tables (Dockets USTR-2026-0265/0266); prior 2026-07-15 receipt: data/research/tariff-matrix-refresh-2026-07-15.md.]

Alternative sourcing options
United States (domestic)
Eliminates tariff exposure entirely — increasingly material now that amino acids, CoQ10, and other pharma-use-only chemical lines carry the 12.5% forced-labor layer on Chinese supplement-use imports (entries on or after Jul 24, 2026; vitamins 2936 remain exempt as entered). US domestic supply is limited and typically 50-100% more expensive for commodity ingredients. Best for brands prioritizing supply chain resilience over cost.
