A word of counsel

The most common error on this tariff line is filing the bill of entry without the Chapter 28 chemical qualifiers — treating the qualifier requirement as a formality to be rectified post-filing rather than a pre-filing obligation. CBIC Circular 23/2023-Cus makes the qualifiers mandatory at the point of entry, and a deficient declaration can result in consignment detention and amendment delays that attract demurrage and ground rent before out-of-charge is granted.
