Last updated: August 2026 dataLysine is an essential amino acid produced primarily by microbial fermentation and is one of the highest-volume amino acid commodities in global trade, used extensively as a feed additive in poultry and swine nutrition. The US schedule distinguishes food-chemical-grade lysine meeting specific purity requirements (2922410010) from other grades (2922410090), a split that matters for both duty treatment and FDA labeling compliance. China dominates supply, with South Korea a significant secondary source; both countries have been subjects of antidumping investigations for lysine in prior trade cycles, making duty-order history a due-diligence item for importers.

Line 2922410010 covers lysine and its salts that meet Food Chemicals Codex (FCC) or equivalent food-grade purity standards, while 2922410090 captures all other grades, including technical or feed-grade material. Importers should confirm the applicable grade with their supplier's certificate of analysis before filing entry to avoid misclassification.
Lysine has historically been the subject of US antidumping proceedings. Importers should query the USITC and Commerce Department's antidumping order database by HTS line and country of origin before shipment, as active orders or suspension agreements can impose significant additional duties beyond the normal column 1 rate.
