A word of counsel

The most common error on this tariff line is filing the bill of entry with a generic product description and omitting the Chapter 32 chemical qualifiers required under para 4.1 and 4.2 of CBIC Circular 23/2023-Cus. A declaration without the stipulated qualifiers will be held for examination and correction before out-of-charge is granted, attracting demurrage and ground rent; the obligation applies equally to spot imports and regular-importer consignments alike.
