U.S. imports of vegetable tanning extracts & preparations, nes (HS 320190) totaled $2.1M in April 2026, traded with 11 countries.
Last updated: April 2026 dataTannic acid and a range of lesser-traded botanical tanning extracts — including chestnut, canaigre, curupay, divi-divi, and eucalyptus — are grouped here when not covered by the quebracho or wattle headings. The US schedule subdivides this heading by tannic acid purity (3201901000 for products with ≥50% tannic acid by weight) and by named botanical sources (3201902500), with a residual NESOI line (3201905000) for everything else. Italy and Belgium lead US imports, reflecting Europe's established role in processing and re-exporting specialty tannin products. Tannic acid lines in particular serve pharmaceutical, food-additive, and ink-manufacturing applications beyond traditional leather tanning.

Tannic acid with ≥50% tannic acid content by weight is specifically captured under 3201901000 regardless of its intended end use. If the product is further processed into a pharmaceutical preparation or food additive, it may shift to a different chapter. Classification should be based on the product's form and composition at the time of importation, not its downstream application.
Line 3201902500 covers extracts from specifically enumerated botanical sources — canaigre, chestnut, curupay, divi-divi, eucalyptus, and others listed in the tariff schedule. Any vegetable tanning extract not covered by quebracho (3201100000), wattle (3201200000), tannic acid (3201901000), or the named botanicals line defaults to the residual 3201905000. Importers should identify the source plant on the commercial invoice to support correct line selection.
