Compliance steps

1
Ensure the importer holds valid registration on the centralised EPR portal for plastic packaging and upload proof of that registration at the bill of entry. Absence of EPR portal registration is a non-compliance trigger under CBIC Instruction 21/2025-Customs dated 02-07-2025.

2
Include all mandatory additional qualifiers in the import declaration for Chapter 39 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, with effect from 15-10-2023. Declarations missing the required qualifiers are liable to rejection at assessment.

A word of counsel

The most common error on this tariff line is filing the bill of entry with complete Chapter 39 qualifiers under the CBIC Circular while omitting the EPR portal registration proof introduced by the later CBIC Instruction 21/2025-Customs. These are independent documentation requirements: compliance with the qualifier regime does not discharge the EPR registration obligation, and a consignment satisfying one but not the other remains liable to out-of-charge denial.

Frequently asked

Does HSN 3908 10 41 require BIS certification?

No, polyamide-6 flake in primary forms is not covered by any BIS Quality Control Order. Import is governed by CBIC customs policy controls — specifically the Chapter 39 mandatory qualifier regime under CBIC Circular 23/2023-Cus and the EPR portal registration requirement under CBIC Instruction 21/2025-Customs.

From what date are the Chapter 39 mandatory qualifiers in import declarations operative?

The mandatory additional qualifiers for commodities under Chapters 28, 29, 32, 39 and CTH 3808 are operative with effect from 15 October 2023, as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023.

Does the EPR portal registration requirement apply to imports of polyamide flake that will be processed into non-packaging end-uses?

CBIC Instruction 21/2025-Customs dated 02-07-2025 requires verification of EPR portal registration for plastic packaging at the import stage; end-use determination is made post-import, so the registration proof must be submitted at the bill of entry regardless of the intended downstream application.
