Compliance steps
  1. 1
    Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 4270:2001 for steel tubes used for water wells. Verify the supplier's CM/L number, licensed product scope, outer diameter 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. 2
    Ensure every tube in the consignment 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 itself, not on packaging alone.

  3. 3
    Register the consignment on the Steel Import Monitoring System portal not earlier than 60 days before the expected arrival date. Fee ₹500, registration valid for 75 days from issue; the registration must remain within validity on the date of arrival.

  4. 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 against the BIS register and the SIMS registration against the DGFT portal in real time; either being absent, expired, or scope-mismatched triggers consignment detention.

  5. 5
    Check whether the consignment qualifies for the QCO exemption under Ministry of Steel Order F.No.S-20011/15/2024-Tech-Part(2) dated 20-11-2025 for bills of lading with a shipped-on-board date on or before 31 March 2026. If exempt, retain the exemption documentation with the bill of entry.

A word of counsel

The single most common error on this tariff line is assuming that IS 4270:2001 covers all seamless cold-drawn steel tubes of this diameter range, when the standard's scope is specifically limited to steel tubes used for water wells. Importers sourcing tubes for structural, mechanical, or industrial fluid-conveyance applications — which may fall within the same 8-digit HSN — risk procuring product licensed only to a water-well specification that does not match the actual end-use requirements, or conversely, presenting tubes under a CM/L that customs finds scope-mismatched. Confirm in writing with the supplier that the licensed specification covers the intended application before the purchase order is placed.

Frequently asked
Does HSN 7304 51 20 require BIS certification?
Yes. Steel tubes for water wells classified under this tariff line require ISI Mark Scheme certification against IS 4270:2001 under the Steel Tubes (Quality Control) Order, 2020 [S.O. 281(E)], with effect from 21 January 2020. Import is permitted only from manufacturers holding a current BIS CM/L licence.
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, validity 75 days, apply no earlier than 60 days before the expected date of arrival.
Is there a transitional exemption from the QCO for shipments already on the water?
Yes, conditionally. Ministry of Steel 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 carries a shipped-on-board date on or before 31 March 2026. Verify whether this HSN appears in the Annexure and retain the documentation.
Does a single CM/L licence cover all tube dimensions and manufacturing facilities?
No. A CM/L licence is scope-specific by outer diameter range, specification, and manufacturing facility. Tubes outside the licensed size range or from an unlicensed plant are not covered and customs will detain the consignment on a scope mismatch.
