Compliance steps

1
At the bill-of-entry stage, ensure the import declaration includes the mandatory additional qualifiers for Chapter 28 commodities as specified in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. These qualifiers cover chemical identity, CAS number, purity, and composition details for inorganic chemicals including complex cyanides.

2
Verify that the supplier's commercial invoice and certificate of analysis align with the declared qualifiers. Mismatch between the import declaration and supporting documents triggers examination and potential detention of the consignment pending re-declaration.

A word of counsel

The most common error on this tariff line is filing the bill of entry without the Chapter 28 mandatory qualifiers, treating the declaration requirement as a procedural formality rather than a clearance condition. A bill of entry lodged without the required qualifiers under paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus is liable to be held for amendment, accruing demurrage and ground rent while the importer obtains corrected supplier documentation.
