Last updated: April 2026 dataChrome-based and other inorganic tanning agents, along with mixed tanning preparations not classified elsewhere, fall under heading 320290. The US schedule separates wholly inorganic tanning substances (3202901000) — predominantly chromium sulfate salts used in chrome tanning — from blended tanning preparations (3202905000) that may combine inorganic and organic components. France leads US imports, followed by Brazil and the Netherlands. Chrome tanning agents are subject to environmental and occupational health scrutiny in many jurisdictions, and importers should be prepared to provide safety data sheets and confirm compliance with any applicable EPA chemical import requirements.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A product combining inorganic and organic tanning components is generally classified as a tanning preparation under 3202905000 rather than as a purely inorganic substance (3202901000) or a vegetable extract (heading 3201). The essential character of the blend and the relative proportions of each component are the key classification factors; a detailed formulation breakdown should accompany the entry.
Imports from China — while not among the top suppliers listed for this heading — could be subject to Section 301 tariffs if sourced from there. Imports from any country should be reviewed for current antidumping or countervailing duty orders on chromium-based chemicals. Consult a licensed customs broker to confirm the current trade-remedy landscape for the specific product and origin.
