Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 10116:2015 for boric acid. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility address on the BIS online register before placing the purchase order.
Bureau of Indian Standards (Standards for Boric Acid) Order, 2019 · S.O. 1766(E) dated 16-05-2019 · General Note 2(a) of the ITC (HS) Import Policy
2
Ensure each consignment of technical-grade boric acid is packed in jute bags with a suitable liner inside and that polishing compounds comprising sulphate and chloride are present within the range specified by CBIC. Non-compliant packing or composition is a standalone ground for consignment detention at port.
CBIC Instruction 03/2024-Cus dated 19-02-2024
3
Obtain an import permit from the Central Insecticides Board and Registration Committee for boric acid intended for non-insecticidal use. Note that import of insecticides is restricted to specified ports under Rule 45 of the Insecticides Rules, 1971; confirm the port of entry is permitted before booking the shipment.

4
Upload the mandatory documents in e-Sanchit before out-of-charge: certificate of analysis (0010DC), batch release certificate (0030DC), label of consignment (0110DC), registration certificate for drugs (101DC1), import licence for drugs (9111DC), and the CIB&RC import permit for non-insecticidal use (911CI3). Customs verifies each document code before granting clearance.

5
Include mandatory additional qualifiers in the import declaration for Chapter 28 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, applicable from 15 October 2023. Quote the supplier's BIS CM/L number on the bill of entry; absence, expiry, or scope mismatch triggers consignment detention.

A word of counsel

The single most common error on this tariff line is treating the BIS QCO as a back-office formality while focusing compliance attention on the CIB&RC import permit. The permit governs the end-use category; the ISI mark under IS 10116:2015 is what permits the consignment to physically clear customs — an unlicensed or out-of-scope CM/L will ground the consignment regardless of the CIB&RC permit status. Separately, the CBIC Instruction 03/2024-Cus packing specification (jute bags with liner, sulphate and chloride within range) is enforced at the point of physical examination and cannot be remedied after arrival.

Frequently asked

Does HSN 2810 00 20 require BIS certification?

Yes. Conformity to IS 10116:2015 is mandatory under the ISI Mark Scheme from 15 October 2023 by virtue of S.O. 1766(E); import is permitted only from manufacturers holding a current BIS CM/L licence covering the relevant product scope and facility.

Is a CIB&RC import permit required separately from BIS QCO compliance?

Yes. An import permit from the Central Insecticides Board and Registration Committee is required for non-insecticidal use of boric acid and is independent of the BIS QCO obligation. Import for insecticidal use is additionally subject to port restrictions under Rule 45 of the Insecticides Rules, 1971.

What packing and composition requirements apply to technical-grade boric acid?

CBIC Instruction 03/2024-Cus requires technical-grade boric acid to be packed in jute bags with a suitable liner and mandates that polishing compounds comprising sulphate and chloride be present within a specified range. Non-compliance with either condition is an independent ground for detention.

Does a single CM/L licence cover all grades and manufacturing facilities of a supplier?

No. A CM/L licence is scope-specific by product grade and manufacturing facility; boric acid grades or plants outside the licensed scope are not covered, and a scope mismatch with the consignment triggers detention at the port of import.
