A word of counsel

The most common error on this tariff line is submitting the bill of entry without the Chapter 28 mandatory qualifiers, treating them as optional supplementary fields. CBIC Circular 23/2023-Cus makes these qualifiers compulsory from 15 October 2023; a declaration filed without them is incomplete on its face, and the proper officer may withhold out-of-charge until the omission is corrected, accruing demurrage and ground rent.
