A word of counsel

The most common error on this tariff line is filing the bill of entry with the chemical composition and HS classification correct but omitting the Chapter 39 mandatory qualifiers required under CBIC Circular 23/2023-Cus — the declaration is rejected outright, not merely flagged for amendment. Separately, the EPR portal registration requirement under CBIC Instruction 21/2025-Customs applies to plastic packaging forms; importers should confirm whether their polyamide primary forms attract EPR obligations before the consignment arrives at port to avoid detention and demurrage.
