Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 1239 (Part 1):2004 for steel tubes and tubulars. Verify the supplier's CM/L number, licensed product scope, size range, and manufacturing facility on the BIS online register before placing the purchase order.
Steel Tubes (Quality Control) Order, 2020 · S.O. 281(E) dated 21-01-2020
2
Ensure every pipe and tube in the consignment bears the ISI mark and the supplier's CM/L number. Marking must appear on the product itself; marking only on outer packaging does not satisfy the BIS (Conformity Assessment) Regulations, 2018.

3
Register the consignment on the Steel Import Monitoring System portal not earlier than 60 days before the expected arrival date. The registration fee is ₹500 and the automatic registration number is valid for 75 days from issue.

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

5
If the consignment is a re-import of steel for packaging purposes, or an SEZ-to-DTA movement without or with value addition, document the applicable SIMS exemption basis in writing. The BIS QCO obligation under IS 1239 (Part 1):2004 is not waived by any SIMS carve-out — the ISI-marked tube requirement continues to apply.

A word of counsel

The most common misclassification error on this tariff line involves octagonal steel columns for lamp posts, which are classifiable under HSN 7308 90 90 and not under HSN 7306 30 10 — importing them under this heading attracts a BIS QCO obligation that does not apply to the correct heading, while simultaneously misrepresenting the product's tariff classification. Customs officers apply Central Board of Indirect Taxes and Customs Circular 17/13-CUS dated 11-04-2013 when reviewing consignments; a misdeclared lamp-post column triggers reclassification, re-assessment of applicable duties and BIS obligations, and potential monetary penalty.

Frequently asked

Does HSN 7306 30 10 require BIS certification?

Yes. Conformity to IS 1239 (Part 1):2004 is mandatory under the ISI Mark Scheme pursuant to the Steel Tubes (Quality Control) Order, 2020; import is permitted only from manufacturers holding a current BIS CM/L licence covering the relevant tube size and manufacturing facility.

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. The registration fee is ₹500, the automatic registration number is valid for 75 days, and application may be made no earlier than 60 days before arrival.

Are octagonal steel columns for lamp posts classifiable under this HSN?

No. Per Central Board of Indirect Taxes and Customs Circular 17/13-CUS dated 11-04-2013, octagonal steel columns for lamp posts are classifiable under HSN 7308 90 90, not HSN 7306 30 10.

Does a single CM/L licence cover all tube sizes and specifications of IS 1239 (Part 1):2004?

No. The CM/L is scope-specific by size range, tube class, and manufacturing facility; tubes outside the licensed scope or from an unlicensed plant are not covered and customs detains the consignment on a scope mismatch.
