A word of counsel

The most common error on this tariff line is filing a bill of entry without the Chapter 28 mandatory qualifiers, treating magnesium hydroxide as a generic inorganic chemical that requires no special declaration. CBIC Circular 23/2023-Cus applies to all Chapter 28 commodities without exception from 15 October 2023; a declaration lacking Para 4.1 and 4.2 qualifiers is flagged for customs examination, and where the end-use is pharmaceutical, the absence of even one of the five drug-category e-Sanchit documents is grounds for detention and demurrage.

Frequently asked

Does HSN 2816 10 10 require BIS certification?

No. Magnesium hydroxide under this tariff line is not covered by any BIS Quality Control Order. The operative compliance framework is CBIC Circular 23/2023-Cus, which mandates additional qualifiers in import declarations for Chapter 28 commodities, plus drug-category documentary requirements where the product is imported as a pharmaceutical input.

When do the five drug-category e-Sanchit documents apply to this HSN?

The five documents — Certificate of Analysis (0010dc), Batch Release Certificate (0030dc), Label of Consignment (0110dc), Registration Certificate for Drugs (101dc1), and Import Licence for Drugs (9111dc) — apply where the consignment has been routed through a PGA for drug-category NOC, and must be uploaded in e-Sanchit before out-of-charge.

Does CBIC Circular 23/2023-Cus apply only to pharmaceutical-grade magnesium hydroxide?

No. The mandatory additional-qualifier requirement under Para 4.1 and 4.2 of CBIC Circular 23/2023-Cus applies to all import declarations for Chapter 28 commodities regardless of end-use, with effect from 15 October 2023.
