Declarations filed without these qualifiers are liable to be held by the proper officer at the port.

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 calcium hydroxide is a commodity chemical requiring no special declaration. CBIC Circular 23/2023-Cus applies to all Chapter 28 commodities without a product-specific carve-out; omission of the paragraph 4.1 and 4.2 qualifiers results in customs hold and demurrage even where the consignment itself is unencumbered by a drug-regime overlay.
