Compliance steps

1
At the time of filing the bill of entry, include all mandatory additional qualifiers for Chapter 28 commodities as specified in Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. Declarations filed without the requisite qualifiers are liable to be treated as incomplete entries, causing consignment detention.

2
Ensure the chemical description on the import declaration accurately identifies the compound as sodium tungstate, consistent with the Chapter 28 qualifier framework. Mismatches between the declared qualifier and the actual compound attract scrutiny and may trigger re-examination or assessment revision.

A word of counsel

The most common error on this tariff line is submitting a bill of entry with a generic Chapter 28 chemical description and omitting the compound-specific qualifiers required under CBIC Circular 23/2023-Cus. The qualifier mandate is not a post-clearance rectification option — an incomplete declaration at the time of filing triggers the proper officer's authority to detain the consignment, and ground rent and demurrage begin accruing immediately at the port of import.
