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, assuming a standard chemical import requires no additional declarations. CBIC Circular 23/2023-Cus is self-executing from 15 October 2023, and a missing qualifier is not a rectifiable labelling defect — it is an incomplete declaration that holds the consignment at the port, accumulating demurrage and ground rent until the entry is re-filed or amended.
