A word of counsel

The most common error on this tariff line is filing the import declaration without the Chapter 39 mandatory qualifiers required under CBIC Circular 23/2023-Cus — an omission that triggers declaration deficiency, consignment detention, and demurrage pending amendment at the port. The EPR portal registration requirement under CBIC Instruction 21/2025-Customs is a separate and concurrent obligation; presenting a valid declaration with correct qualifiers does not substitute for the EPR registration proof, and its absence independently prevents out-of-charge.
