Other cellulose ethers in primary forms
HSN 3912 39 19 (Other cellulose ethers) is subject to Central Board of Indirect Taxes and Customs (CBIC) policy overlays governing Chapter 39 chemical imports. Mandatory additional qualifiers in import declarations under CBIC Circular 23/2023-Cus are required with effect from 15 October 2023, and importers must demonstrate proof of registration on the Centralised EPR Portal for Plastic Packaging under CBIC Instruction 21/2025-Customs.
- EPR Portal registration proof from CBIC
- Chapter 39 qualifiers declaration from CBIC
- 1Include all mandatory additional qualifiers in the import declaration for commodities under Chapter 39 as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. This requirement has been operative with effect from 15 October 2023 and non-compliant declarations are liable to being held up at the bill-of-entry stage.CBIC Circular 23/2023-Cus dated 30-09-2023, paragraphs 4.1 and 4.2
- 2Verify and upload proof of registration on the Centralised EPR Portal for Plastic Packaging before filing the bill of entry. Failure to demonstrate valid EPR registration attracts detention and out-of-charge denial under CBIC Instruction 21/2025-Customs.CBIC Instruction 21/2025-Customs dated 02-07-2025
The most common error on this tariff line is overlooking the EPR portal-registration requirement when cellulose ethers are imported as chemical intermediates rather than finished plastic packaging — CBIC Instruction 21/2025-Customs applies to plastic packaging commodities under Chapter 39 regardless of downstream use. Importers who treat the Chapter 39 qualifier obligation and the EPR registration as independent tasks risk simultaneous deficiency flags at the bill-of-entry stage, triggering detention and demurrage at port.
