A word of counsel

The most common error on this tariff line is filing the bill of entry without the Chapter 28 mandatory qualifiers on the assumption that potash alum is a standard inorganic chemical attracting no PGA scrutiny. CBIC Circular 23/2023-Cus applies across the entire chapter — there is no carve-out for alums — and a declaration missing Paragraphs 4.1/4.2 qualifiers is treated as a deficient entry, triggering a stop for amendment that generates demurrage and ground rent before out-of-charge is granted.

Frequently asked

Does HSN 2833 30 30 require BIS certification?

No, potash alum is not covered by any BIS Quality Control Order. Import is governed by the Central Board of Indirect Taxes and Customs under CBIC Circular 23/2023-Cus, which mandates additional qualifiers in the import declaration for all Chapter 28 commodities effective 15 October 2023.

Which e-Sanchit documents must be uploaded when potash alum is imported as a drug?

Five documents are mandatory: Certificate of Analysis (0010dc), Batch Release Certificate (0030dc), Label of Consignment (0110dc), Registration Certificate for Drugs (101dc1), and Import Licence for Drugs (9111dc); all must be uploaded before customs out-of-charge.

Does the CBIC Circular 23/2023-Cus qualifier requirement apply if potash alum is not classified as a drug?

Yes. The mandatory additional-qualifier obligation under Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus applies to all Chapter 28 import declarations regardless of drug classification; only the additional drug-specific e-Sanchit documents are conditional on drug classification.
