Last updated: August 2026 dataSyntans — synthetic organic tanning substances — are engineered chemical alternatives to vegetable tannins, widely used in modern tanneries for their consistency, faster penetration, and ability to produce lighter-colored leathers. The US schedule distinguishes aromatic and modified-aromatic syntans (3202101000) from non-aromatic types (3202105000), a split that reflects differences in molecular structure and environmental compliance profiles. Germany leads US imports, consistent with its position as a global center for specialty leather chemicals, with Brazil and Mexico also significant sources. Importers should note that aromatic syntans may be subject to additional scrutiny under chemical import regulations depending on specific compound identity.

Aromatic and modified-aromatic syntans (3202101000) contain benzene-ring structures in their molecular backbone, which affects both their tanning performance and their regulatory profile under chemical safety frameworks. Non-aromatic syntans (3202105000) lack these ring structures. The distinction requires a chemical specification sheet or SDS confirming molecular structure; importers should obtain this documentation from the manufacturer before entry.
Synthetic organic chemicals may be subject to TSCA Section 13 import certification requirements if they are not listed on the TSCA Chemical Substance Inventory or if they are subject to a TSCA rule or order. Importers should confirm TSCA status for each specific compound with their customs broker or regulatory counsel before shipment.
