A word of counsel

The most common error on this tariff line is failing to determine at the procurement stage whether the manganese sulphate shipment will be classified as a drug at the port of import. If the end-use or accompanying documentation indicates pharmaceutical application, all five drug-category document codes become mandatory in e-Sanchit; a consignment arriving with only a Certificate of Analysis and no registration certificate or import licence for drugs will be detained pending PGA NOC routing, accruing demurrage and ground rent that cannot be waived retrospectively.

Frequently asked

Does HSN 2833 29 40 require BIS certification?

No, manganese sulphate is not covered by any BIS Quality Control Order. Import compliance is governed by the Central Board of Indirect Taxes and Customs under CBIC Circular 23/2023-Cus requiring mandatory Chapter 28 qualifiers in the import declaration, with additional drug-regime document requirements where the product is imported as a pharmaceutical.

Which document codes must be uploaded in e-Sanchit when manganese sulphate is imported as a drug?

Five document codes are mandatory: Certificate of Analysis — Drug (0010dc), Batch Release Certificate (0030dc), Label of Consignment (0110dc), Registration Certificate — Drugs (101dc1), and Import Licence for Drugs (9111dc); all must be present in e-Sanchit before the proper officer grants out-of-charge.

Do the Chapter 28 mandatory qualifiers under CBIC Circular 23/2023-Cus apply to non-drug imports of manganese sulphate as well?

Yes. The mandatory additional qualifier requirement under paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus applies to all import declarations for Chapter 28 commodities from 15 October 2023, regardless of whether the specific consignment is also subject to the drug-regime document requirements.
