BIS QCO APPLICABLE · ISI MARK SCHEME · SIMS OVERLAY

HSN 7304 59 20 (seamless alloy steel pipes and tubes above 114.3 mm but up to 219.1 mm outer diameter) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 4270:2001 is mandatory under the ISI Mark Scheme with effect from 21 January 2020, by virtue of the Steel Tubes (Quality Control) Order, 2020 vide S.O. 281(E). Steel Import Monitoring System registration administered by the Directorate General of Foreign Trade applies as a separate customs-clearance overlay.

Compliance steps

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
Ensure every pipe or tube bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. The marking must appear on the product itself and not solely on packaging or documentation.

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

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 number against the DGFT portal; either being absent, expired, or scope-mismatched triggers consignment detention.

5
Check whether the consignment qualifies for the transitional QCO exemption under MoS Order F.No.S-20011/15/2024-Tech-Part(2) dated 20-11-2025. Consignments with a bill of lading shipped-on-board date on or before 31 March 2026 may be exempt if the HSN code is listed in Annexure I of that order; retain documentary evidence of the bill of lading date.

A word of counsel

The single most common error on this tariff line is treating IS 4270:2001 as a general-purpose seamless-alloy-steel-tube standard when its scope is specific to steel tubes used for water wells. Importers sourcing seamless alloy steel tubes for structural, mechanical, or process-plant applications in the 114.3–219.1 mm diameter band often present a CM/L licence issued for a different IS number; customs verifies scope specificity against the BIS register and detains consignments where the licensed scope does not cover water-well tube applications.

Frequently asked

Does HSN 7304 59 20 require BIS certification?

Yes. Steel tubes within this outer diameter band require conformity to IS 4270:2001 under the ISI Mark Scheme with effect from 21 January 2020, pursuant to the Steel Tubes (Quality Control) Order, 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. The fee is ₹500, the registration is valid for 75 days, and application may be made no earlier than 60 days before the expected date of arrival.

Does the transitional MoS exemption relieve the BIS QCO obligation for this HSN?

Only if the specific ITC HS code appears in Annexure I of MoS Order F.No.S-20011/15/2024-Tech-Part(2) dated 20-11-2025, and the bill of lading shipped-on-board date is on or before 31 March 2026. Importers must retain the bill of lading as evidence; the BIS obligation continues for all subsequent consignments outside that window.

Does a single CM/L licence cover seamless alloy steel tubes across all applications in this diameter range?

No. IS 4270:2001 is scoped to steel tubes for water wells; a CM/L licence issued under a different IS number, even for a physically identical tube dimension, does not satisfy the QCO obligation. The licence must expressly cover IS 4270:2001 and the relevant outer diameter range.
