Compliance steps

1
Verify the foreign manufacturer holds a current BIS CM/L licence against the Indian Standard specified in Schedule 1 of the Steel and Steel Products Quality Control Order, 2024 for this product category. Confirm the licensed scope covers the hollow section dimensions and facility of manufacture before placing the purchase order.

2
Ensure the consignment is accompanied by two test certificates: one for the finished hollow section itself (Schedule 2, serial number 2) and one bearing the BIS standard mark for the stainless steel input material, issued by the BIS-certified input manufacturer.

3
Register the consignment on the SIMS portal not earlier than 60 days before the expected arrival date, paying the ₹500 registration fee. The automatic registration number is valid for 75 days; confirm it remains within validity on the date of arrival.

Ensure strict compliance with CBIC Instruction 16/25-CUS dated 18-06-2025 as modified by CBIC Instruction 23/25-CUS dated 15-07-2025 regarding the Indian Standard of the respective input material of steel products intended for import as notified and mapped in the QCO, and requiring mandatory SIMS portal registration.

5
If the consignment does not carry BIS certification, apply for and obtain clarification on the TCQCO portal before arrival. Quote the BIS CM/L number, SIMS registration number, and both test certificates on the bill of entry; any one absent or scope-mismatched triggers consignment detention.

A word of counsel

The most frequent compliance failure on this tariff line is treating the finished-product CM/L as the sole documentation requirement while overlooking the mandatory dual test-certificate obligation — one for the hollow section and one for the BIS-marked input material. Customs officers check both certificates independently at port; arrival with only the finished-product certificate, or with an input-material certificate from a non-BIS-certified mill, results in consignment detention regardless of the validity of the finished-product CM/L licence. Confirm input-material BIS certification in the supplier's mill test reports at order stage, not at port.

Frequently asked

Does HSN 7306 61 00 require BIS certification?

Yes. Square and rectangular hollow section tubes under this tariff line require a Bureau of Indian Standards CM/L licence under the ISI Mark Scheme against the Indian Standard specified in Schedule 1 of the Steel and Steel Products Quality Control Order, 2024 notified vide S.O. 3716(E).

Is SIMS 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; fee ₹500, validity 75 days, application permitted no earlier than 60 days before the expected arrival date.

Are there any carve-outs from the SIMS registration requirement?

Yes. Re-import of steel goods solely for packaging purposes and SEZ-to-DTA movements (with or without value addition) are exempt from SIMS registration per DGFT policy circular 38/2015-20 dated 19-01-2022; the BIS QCO obligation is not waived by either carve-out.

Does a single CM/L licence cover all hollow section sizes and all manufacturing facilities of the supplier?

No. A CM/L licence is specific to the licensed product scope, dimensional range, and manufacturing facility; hollow sections outside the licensed dimensions or produced at an unlicensed plant are not covered and will be detained at port.
