Import Tips

• Verify certificate of analysis confirming ≥50% tannic acid content to meet HTS 3201.90.10.00 criteria and avoid reclassification as pure chemicals

• Ensure supplier documentation traces vegetable origin (e.g

• gallotannins from plants) to comply with chapter exclusions for synthetic compounds

• Label clearly as 'tannic acid' with purity percentage; common pitfall is insufficient documentation leading to higher duties under Chapter 29
