A word of counsel

The most common error on this tariff line is submitting the bill of entry without the Chapter 28 mandatory qualifiers, on the assumption that aluminium sulphate — a commodity chemical — carries no special declaration burden. CBIC Circular 23/2023-Cus makes the additional qualifiers obligatory for all Chapter 28 import declarations regardless of end-use; a qualifier-deficient bill of entry is flagged for reassessment, accumulating demurrage and ground rent while the declaration is corrected.

Frequently asked
Does HSN 2833 22 10 require BIS certification?
No. No BIS Quality Control Order covers aluminium sulphate under this tariff line.

When do the drug-related e-Sanchit documents apply, and which codes must be uploaded?
The drug-regime documents — Certificate of Analysis (0010dc), Batch Release Certificate (0030dc), Label of Consignment (0110dc), Registration Certificate for Drugs (101dc1), and Import Licence for Drugs (9111dc) — are required where the consignment is routed as a drug or drug-manufacturing input and the bill is PGA-facilitated without a separate NOC routing.
From what date are the Chapter 28 additional qualifiers mandatory, and which chapters are covered?
The additional qualifiers are mandatory with effect from 15 October 2023 under CBIC Circular 23/2023-Cus, applying to import declarations for commodities under Chapters 28, 29, 32, 39 and CTH 3808.
