Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the Indian Standard mapped to HSN 7304 31 19 in Schedule 1 of the Steel and Steel Products Quality Control Order, 2024. Verify the CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure every pipe or tube bears the ISI standard mark under the supplier's CM/L licence in accordance with Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself; marking on packaging alone does not satisfy the requirement.

3
Obtain a test certificate bearing the standard mark from the BIS-certified manufacturer and ensure it accompanies each consignment. Sub-standard or defective product that does not conform to the specified standard must be disposed of as scrap in compliance with Section 17(1)(b) of the BIS Act, 2016.

4
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. Re-imports for packaging purposes and SEZ-to-DTA movements without value addition are exempt from SIMS registration.

Verify whether the consignment qualifies for the transitional exemption under MoS Order F.No. S-20011/15/2024-TECH-Part(2) dated 20-11-2025: consignments with bill of lading shipped-on-board date on or before 31 March 2026 and listed in Annexure I of that order are exempt from mandatory QCO compliance. Additionally, confirm strict compliance with CBIC Instruction 16/2025-CUS dated 18-06-2025 as modified by CBIC Instruction 23/2025-CUS dated 15-07-2025 on input-material Indian Standard mapping on the SIMS portal.

A word of counsel

The most consequential error on this tariff line is conflating the SIMS registration date — which has been enforced since September 2020 under DGFT Notification 33/2015-20 — with the BIS QCO enforcement date under S.O. 3716(E), which is 29 August 2024. Importers who relied on SIMS-clean consignments before August 2024 without a CM/L-marked product now face retrospective scrutiny under the 2024 QCO at port. The transitional exemption under the MoS Order dated 20 November 2025 is conditional on the shipped-on-board date and Annexure I coverage — both must be confirmed before the bill of entry is filed, not after customs queries the consignment.

Frequently asked

Does HSN 7304 31 19 require BIS certification?

Yes. Seamless cold-drawn or cold-rolled circular tubes and pipes under this tariff line must conform to the Indian Standard in Schedule 1 of the Steel and Steel Products Quality Control Order, 2024 under the ISI Mark Scheme; import is permitted only from manufacturers holding a current BIS CM/L licence.

Is Steel Import Monitoring System registration required separately from BIS QCO compliance?

Yes. SIMS registration is administered by the Directorate General of Foreign Trade and is independent of the BIS QCO obligation. Fee ₹500, validity 75 days, apply no earlier than 60 days before expected arrival; re-imports for packaging purposes and SEZ-to-DTA movements without value addition are exempt.

Does the transitional exemption under the MoS Order dated 20 November 2025 waive the BIS QCO requirement?

Only for consignments whose bill of lading carries a shipped-on-board date on or before 31 March 2026 and whose ITC HS code is listed in Annexure I of that order. All other consignments must comply with the full QCO obligation under S.O. 3716(E).

Does a single CM/L licence cover all pipe dimensions and specifications under HSN 7304 31 19?

No. A CM/L licence is scope-specific by Indian Standard, size range, and manufacturing facility; pipes outside the licensed specification or from an unlicensed plant are not covered, and a scope mismatch at customs triggers consignment detention.
