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, size range, and manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure every pipe or tube bears the ISI mark and the supplier's CM/L number per Scheme-I of the BIS (Conformity Assessment) Regulations, 2018. The marking must appear on the product itself, not on packaging alone.

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

5
Check whether the bill of lading shipped-on-board date is on or before 31-03-2026 and whether this ITC HS code appears in Annexure I of the Ministry of Steel order F.No. S-20011/15/2024-Tech-Part(2) dated 20-11-2025. Consignments satisfying both conditions are exempted from mandatory QCO compliance for that shipment.

A word of counsel

The single most common error on this tariff line is assuming that SIMS registration exhausts the import-compliance obligation — consignees with a valid SIMS automatic registration number but a supplier whose CM/L licence does not extend to the specific outer-diameter range above 219.1 mm face detention and potential confiscation under the Steel Tubes (Quality Control) Order, 2020. IS 4270:2001 scope is water-well tube applications; confirm in writing that the consignment's end-use and specification fall squarely within that scope, or the CM/L licence presented at customs will be rejected as mismatched.

Frequently asked

Does HSN 7304 51 30 require BIS certification?

Yes. Conformity to IS 4270:2001 is mandatory under the ISI Mark Scheme by virtue of the Steel Tubes (Quality Control) Order, 2020 [S.O. 281(E)]; import is permitted only from manufacturers holding a current BIS CM/L licence covering the relevant outer-diameter range.

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 obligation. Fee ₹500, validity 75 days, apply no earlier than 60 days before expected arrival.

Is there any transitional exemption from the QCO for this HSN?

Potentially. The Ministry of Steel order F.No. S-20011/15/2024-Tech-Part(2) dated 20-11-2025 exempts listed ITC HS codes from mandatory QCO compliance where the bill of lading shipped-on-board date is on or before 31-03-2026; importers must verify whether this HSN appears in Annexure I of that order.

Does a single CM/L licence cover all outer-diameter variants and manufacturing facilities?

No. A CM/L licence is scope-specific by size range, product specification, and manufacturing facility; tubes above 219.1 mm outer diameter from a plant or size range outside the licensed scope are not covered, and customs will detain the consignment on a scope mismatch.
