Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer whose licence covers pilfer-proof caps made from tin plate or tin-free steel as input materials, conforming to the Indian Standards at Serial Numbers 108 and 109 in Schedule 1 of the Steel and Steel Products QCO 2024. Verify the CM/L number, product scope, and licensed facility on the BIS online register before placing the purchase order.
Steel and Steel Products (Quality Control) Order, 2024 · S.O. 3716(E) dated 29-08-2024 · Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018
2
Ensure that each consignment is accompanied by the Test Certificate of the input material (tin plate or tin-free steel). This certificate must confirm the input material conforms to the Indian Standard specified in Column (2) of Schedule 1 of the QCO and is ISI-marked under a BIS licence.

3
Ensure each pilfer-proof cap bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product or its immediate packaging where direct product marking is physically impracticable.

4
Register the consignment on the Steel Import Monitoring System (SIMS) portal and obtain the SIMS registration number. Compliance with CBIC Instruction No. 16/25-CUS dated 18-06-2025, as modified by CBIC Instruction No. 23/25-Cus dated 15-07-2025, is mandatory for the Indian Standard of the respective input material of steel and steel products requiring SIMS registration.

5
Where the consignment is imported without BIS licence or certification, apply for and obtain clarification on the TCQCO portal before import, per the Ministry of Steel Circular dated 20-10-2023. Quote the BIS CM/L number and SIMS registration number on the bill of entry; absent or mismatched references trigger consignment detention.

A word of counsel

The critical error on this tariff line is focusing solely on the finished-article BIS marking while overlooking the input-material certification requirement. The Steel and Steel Products QCO 2024 mandates that the tin plate or tin-free steel used as input material itself bears the ISI standard mark under a separate BIS CM/L licence, and the consignment must be accompanied by the Test Certificate of that input material — a consignment with a correctly marked finished cap but an uncertified input material is non-compliant and liable to detention at port.

Frequently asked

Does HSN 8309 90 10 require BIS certification?

Yes. Pilfer-proof caps of base metal are subject to the ISI Mark Scheme under the Steel and Steel Products (Quality Control) Order, 2024, S.O. 3716(E); import from manufacturers without a current BIS CM/L licence covering the applicable Indian Standard has been prohibited with effect from 29 August 2024.

Is SIMS registration required separately from BIS QCO compliance?

Yes. Steel Import Monitoring System registration is a separate customs-clearance requirement administered through the SIMS portal, mandatory for the input materials of steel and steel products as notified under CBIC Instruction No. 16/25-CUS dated 18-06-2025 and CBIC Instruction No. 23/25-Cus dated 15-07-2025.

What is the input-material certification requirement under the QCO?

Articles falling under Serial Numbers 3 to 7 of Schedule 2 of the QCO must be made from ISI-marked tin plate or tin-free steel as specified at Serial Numbers 108 and 109 of Schedule 1; a Test Certificate of the input material must accompany each consignment.

Does a single CM/L licence cover all cap variants and washers or fittings from the same manufacturer?

No. The CM/L licence is scope-specific by product specification, input-material grade, and manufacturing facility; cap variants, fitment combinations, or material configurations outside the licensed scope are not covered and customs will detain any consignment where the bill of entry specification falls outside the licensed scope.
