A word of counsel

The most frequent error on Chapter 32 dye imports is filing a generic product description at the bill of entry and appending the mandatory qualifiers only after a customs query. CBIC Circular 23/2023-Cus requires the qualifiers to be present in the original declaration; a post-facto amendment triggers reassessment, demurrage, and potential ground rent liability for the period of detention pending correction.
