Compliance steps

1
Where the carbonate is imported for insecticidal, fungicidal, herbicidal, or rodenticidal use, obtain a valid registration certificate or import permit from the Central Insecticides Board and Registration Committee under Section 9 of the Insecticides Act, 1968. Import is restricted to the source specified on the certificate or permit; sourcing from any other origin constitutes a breach of registration conditions.
Section 9 of the Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · CBIC Circulars 35/2011 dated 09-08-2011 and 7/2014 dated 07-03-2014
2
Where the carbonate falls within a food-grade application, upload the FSSAI Import Licence (document code 911001), Specimen Copy of Label (document code 0110FS), and any required Certificate of Analysis (document code 0010dc) in e-Sanchit before filing the bill of entry. Route the consignment only through a designated food-import entry point in compliance with General Note 4(D) of Schedule I of the ITC (HS) 2022.
CBIC Instruction 10/2022-Cus dated 28-06-2022 · CBIC Instruction 09/2023-Cus dated 07-03-2023 · FSSAI order dated 18-11-2022 under F.No.Import/TFM/Apex/2022-FSSAI
3
Include all mandatory additional qualifiers for Chapter 28 commodities in the import declaration with effect from 15 October 2023, as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. Where the substance is a specified hazardous chemical imported in excess of notified threshold quantities, obtain a Public Liability Insurance policy under S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this residual tariff line is misidentifying the applicable regulatory track: importers shipping carbonates for industrial or chemical purposes assume neither the CIB&RC nor the FSSAI regime applies, only to face detention when the customs proper officer identifies an agricultural or food-adjacent end-use. The intended end-use governs which PGA registration must be produced at the bill of entry; a mismatch between the declared end-use and the actual application can attract seizure and prosecution under the Insecticides Act, 1968, independently of any FSSAI contravention.

Frequently asked

Does HSN 2836 99 90 require BIS certification?

No, residual carbonates and peroxocarbonates are not within the BIS Quality Control Order regime. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where insecticidal use is intended, and by the Food Safety and Standards Authority of India under the Food Safety and Standards Act, 2006 for food-grade applications.

Are the Chapter 28 additional qualifiers in the import declaration mandatory, and from what date?

Yes. Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30 September 2023 require mandatory additional qualifiers for all import declarations covering Chapter 28 commodities, with effect from 15 October 2023.

What happens if a carbonate is imported for a non-insecticidal purpose without a CIB&RC permit?

An import permit from the Registration Committee under the Department of Agriculture and Cooperation is still required for non-insecticidal purposes under the Insecticides Act, 1968; importing without it exposes the consignment to seizure and the importer to prosecution, as affirmed in the Supreme Court order reported at 2002 (146) ELT 19 (SC).
