Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the Indian Standard mapped in Schedule 1 of the Steel and Steel Products Quality Control Order 2024. Verify the supplier's CM/L number, licensed product scope, pipe dimensions, and manufacturing facility address on the BIS online register before placing the purchase order.

2
Ensure each consignment is accompanied by a test certificate bearing the standard mark, issued by the BIS-licensed manufacturer. The test certificate and the ISI mark on the product must both be traceable to the specific CM/L licence number and the manufacturing facility.

3
Register the consignment on the Steel Import Monitoring System portal not earlier than 60 days before the expected date of arrival. Fee ₹500; the automatic registration number is valid for 75 days. Strict compliance is required under CBIC Instruction 16/2025-CUS and its modification by CBIC Instruction 23/2025-CUS with respect to the Indian Standard of the input material.

4
Quote both the supplier's BIS CM/L number and the SIMS automatic registration number on the bill of entry. Customs cross-verifies each against the BIS register and the DGFT SIMS portal; either being absent, expired, or scope-mismatched triggers consignment detention.

If the bill of lading shipped-on-board date is on or before 31 March 2026, verify whether this ITC HS code is listed in Annexure I of MoS Order F.No. S-20011/15/2024-Tech-Part(2) dated 20-11-2025, which exempts specified HSN codes from mandatory QCO compliance for that shipment cohort. Document the exemption basis on the bill of entry where applicable.

A word of counsel

The single most common error on this tariff line is assuming that SIMS registration satisfies the full compliance obligation — it does not. The BIS QCO under S.O. 3716(E) requires that every pipe bear the ISI mark under a current CM/L licence, and that each consignment carry a manufacturer-issued test certificate bearing the standard mark; a consignment with a valid SIMS registration but from an unlicensed manufacturer, or without the prescribed test certificate, is liable to detention and disposal as scrap under clause (b) of sub-section (1) of Section 17 of the BIS Act, 2016. Verify the CM/L scope against pipe dimensions before the purchase order, not at the port gate.

Frequently asked

Does HSN 7304 51 10 require BIS certification?

Yes. Seamless cold-drawn or cold-rolled alloy steel pipes and tubes up to 114.3 mm diameter fall within Schedule 1 of the Steel and Steel Products Quality Control Order 2024 and must be imported only from manufacturers holding a current Bureau of Indian Standards CM/L licence under the ISI Mark Scheme, with effect from 29 August 2024.

Is SIMS registration required separately from BIS QCO compliance?

Yes. Steel Import Monitoring System registration is administered by the Directorate General of Foreign Trade and is independent of the BIS QCO obligation; fee ₹500, registration valid 75 days, apply no earlier than 60 days before the expected date of arrival.

Is there a temporary exemption from the mandatory QCO requirement for this tariff line?

Possibly. MoS Order F.No. S-20011/15/2024-Tech-Part(2) dated 20-11-2025 exempts ITC HS codes listed in its Annexure I from mandatory QCO compliance where the bill of lading shipped-on-board date is on or before 31 March 2026; importers must confirm whether this HSN code appears in that Annexure and document the exemption basis.

Does a single CM/L licence cover all pipe dimensions and manufacturing facilities?

No. The CM/L licence is scope-specific by pipe dimension range, specification, and manufacturing facility; pipes outside the licensed dimensional range or from a different plant are not covered and attract detention at port.
