A word of counsel

The most common error on this tariff line is filing the bill of entry without populating the Chapter 28 mandatory qualifier fields, treating them as optional descriptors rather than binding declaration requirements. CBIC Circular 23/2023-Cus applies to all commodities under Chapters 28, 29, 32, 39 and CTH 3808; a deficient entry is not self-correcting at out-of-charge and will result in detention until the qualifiers are furnished, accruing demurrage and ground rent.
