Compliance steps

1
Verify the foreign manufacturer holds a current BIS CM/L licence against IS 17876:2022 on the BIS online register before placing the purchase order. Confirm the licensed scope covers the specific pipe grade, dimensional range, and manufacturing facility from which the consignment will be sourced.

2
Ensure each pipe bears the ISI mark under licence per Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. The marking must appear on the product itself; packaging-only marking does not satisfy the BIS QCO requirement.

3
Obtain and accompany the consignment with two test certificates: (a) a test certificate for the finished stainless steel pipes and tubes; and (b) a test certificate bearing the ISI standard mark for the stainless steel input material, issued by a BIS-certified manufacturer.

4
Register the consignment on the Steel Import Monitoring System portal no earlier than 60 days before the expected arrival date. Pay the registration fee of ₹500 and obtain the automatic registration number, which remains valid for 75 days from issue.

5
Check whether the consignment qualifies for the BIS QCO exemption under MoS Order F.No.S-20011/15/2024-Tech-Part(2) dated 20-11-2025: ITC HS codes listed in Annexure I with a bill of lading shipped-on-board date on or before 31 March 2026 are exempt from mandatory QCO compliance. If no exemption applies, also comply with CBIC Instructions 16/25-CUS and 23/25-CUS requiring SIMS portal registration for the input material Indian Standard.

A word of counsel

The most common compliance failure on this tariff line is treating IS 17876:2022 as covering only the finished pipe while overlooking the mandatory dual test-certificate requirement — one for the finished stainless steel pipe and a separate certificate for the stainless steel input material from a BIS-certified mill. Customs has authority to detain the consignment solely for absence of the input-material test certificate even where the finished-pipe CM/L and ISI marking are in order. Importers should obtain both certificates from the supplier before the shipment departs the origin port.

Frequently asked

Does HSN 7305 31 90 require BIS certification?

Yes. Longitudinally welded large-diameter stainless steel pipes and tubes under this tariff line require conformity to IS 17876:2022 under the ISI Mark Scheme with effect from 01 August 2025; import is permitted only from manufacturers holding a current BIS CM/L licence covering the relevant grade, size, and facility.

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; the registration fee is ₹500, the automatic registration number is valid for 75 days, and registration may be applied for no earlier than 60 days before the expected arrival date.

Is there any exemption from the BIS QCO obligation for this tariff line?

Yes, conditionally. The MoS Order dated 20-11-2025 exempts ITC HS codes listed in Annexure I where the bill of lading carries a shipped-on-board date on or before 31 March 2026; importers must verify whether HSN 7305 31 90 appears in that Annexure and retain documentary evidence of the shipped-on-board date.

Does a single CM/L licence cover all pipe grades and sizes from the same manufacturer?

No. A CM/L licence is scope-specific by grade, dimensional range, and manufacturing facility; pipes outside the licensed scope or from an unlicensed plant are not covered and will be detained at customs.
