Last updated: April 2026 dataDerived from bark, wood, and plant galls, vegetable tannins and their salts, ethers, esters, and other chemical derivatives are foundational inputs for the leather-tanning, ink, and pharmaceutical industries. Classification turns on whether the product is a crude extract, a purified tannin, or a chemically modified derivative — distinctions that affect both duty treatment and end-use documentation. Quebracho, chestnut, and mimosa (wattle) extracts are among the most commercially significant forms traded under this heading.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Crude extracts retain a mixture of tannins alongside non-tannin plant matter, while purified tannins are isolated active compounds. Chemically modified forms — salts, ethers, or esters — are classified as derivatives. Importers should document the degree of processing and chemical composition to support the correct classification, ideally with a licensed customs broker's guidance.
Leather tanneries are the largest consumers, using vegetable tannins to produce full-grain and vegetable-tanned leather. Secondary markets include wine and beverage fining, wood adhesives, and pharmaceutical excipients, each of which may require different purity specifications from the supplier.
