A word of counsel

The most common error on this tariff line is filing the bill of entry without completing the Chapter 28 mandatory qualifiers, treating them as optional supplementary data. CBIC Circular 23/2023-Cus makes these qualifiers a condition of out-of-charge from 15 October 2023; a declaration with missing qualifiers is treated as an incomplete entry and attracts detention and ground rent while reassessment is pending.

Frequently asked
Does HSN 2849 20 90 require BIS certification?
No, silicon carbides under this residual tariff line are not covered by any BIS Quality Control Order. Import compliance is governed solely by CBIC Circular 23/2023-Cus, which mandates mandatory additional qualifier declarations in the bill of entry for all Chapter 28 commodities.
What are the mandatory qualifiers required under CBIC Circular 23/2023-Cus for Chapter 28 entries?
Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus specify the qualifier fields that must be completed for Chapter 28 import declarations; importers should consult the circular directly for the current field-level requirements applicable with effect from 15 October 2023.
Does the same circular apply to related chemical chapters, or is it limited to Chapter 28?
CBIC Circular 23/2023-Cus extends to commodities under Chapters 28, 29, 32 and 39, and CTH 3808; the mandatory qualifier regime is therefore broader than Chapter 28 alone, but only the Chapter 28 requirements apply to HSN 2849 20 90.
