Import Tips
• Verify purity certificate showing stearic acid content >90% to confirm classification under 2915.70.01 vs mixtures in Chapter 38
• Include CAS number 822-16-2 on commercial invoice and SDS for chemical identification during CBP review
• Avoid common pitfall of mislabeling as 'soap' which shifts to Chapter 34; specify as 'industrial chemical salt'
