A word of counsel

The most common error on this tariff line is filing the bill of entry with a generic chemical description and omitting the specific qualifiers mandated for Chapter 28 commodities under CBIC Circular 23/2023-Cus. An incomplete declaration triggers examination and reassessment, with attendant demurrage and ground rent accumulating from the date of vessel arrival. Ensure the exporter's commercial invoice and packing list already carry the required qualifier data so the bill of entry can be filed accurately from the outset.
