The weight thresholds that define this heading — 8 kg dried, 10 kg dry-salted, 16 kg fresh or wet-salted — are measured in the condition as presented at import. A skin that exceeds the applicable threshold in its preserved state may reclassify to a heavier-hide heading, so accurate weight documentation by preservation method is essential for correct entry.

Raw hides and skins of animal origin may be subject to USDA APHIS review for disease risk, particularly when sourced from countries with foot-and-mouth disease or other reportable animal diseases. Importers should verify current APHIS admissibility conditions for the specific country of origin before shipment, and consult a licensed customs broker or APHIS directly for current requirements.
