Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the applicable Indian Standard for the specific fastener type being imported. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure every consignment is accompanied by a test certificate bearing the BIS standard mark issued by the CM/L-licensed manufacturer. Each product must bear the standard mark under the CM/L licence; sub-standard or defective product must be disposed of as scrap in accordance with Section 17(1)(b) of the BIS Act, 2016.

3
Register the consignment on the Steel Import Monitoring System portal not earlier than 60 days before the expected date of arrival. Fee ₹500; the automatic registration number is valid for 75 days. Re-imports for packaging only and SEZ-to-DTA movements without value addition are exempt from SIMS registration.

4
If importing without a BIS licence or certification, apply for and obtain a clarification on the TCQCO portal before shipment, as mandated for all steel importers. Ensure compliance with the Central Board of Indirect Taxes and Customs clarification on this requirement, including CBIC Instructions 16/2025-Customs and 23/2025-Customs.

5
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; an absent, expired, or scope-mismatched CM/L or SIMS registration triggers consignment detention.

A word of counsel

The single most common failure on this tariff line is treating the SIMS registration as sufficient while overlooking that this residual HSN maps to multiple distinct Indian Standards — IS 3298 for mild steel rivet bars, IS 1363, IS 1364, IS 3757, IS 6623, IS 12427, IS 15833, and others — each licence being scope-specific to fastener type, size range, and product grade. A CM/L licence held by the supplier against IS 3757 (high-strength structural bolts) does not cover rivets under IS 3298; importing outside the exact licensed product scope exposes the consignment to detention and disposal as scrap under Section 17(1)(b) of the BIS Act, 2016, regardless of a valid SIMS registration.

Frequently asked

Does HSN 7318 29 90 require BIS certification?

Yes. The Steel and Steel Products (Quality Control) Order, 2024 mandates conformity to the applicable Indian Standard under the ISI Mark Scheme with effect from 18 June 2025; import is permitted only from manufacturers holding a current BIS CM/L licence covering the specific fastener type and size 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 QCO obligation. Fee ₹500, validity 75 days; apply no earlier than 60 days before the expected date of arrival.

Which Indian Standard applies to this tariff line?

Multiple standards apply depending on fastener type: IS 3298 for mild steel rivet bars, IS 1363 (Parts 1–3) and IS 1364 (Parts 1–2) for hexagon fasteners of product grades C and A/B respectively, IS 3757 for high-strength structural bolts, IS 6623 for high-strength structural nuts, IS 12427 for transmission tower bolts, IS 15833 for stainless steel tower bolts, and others. The CM/L must match the exact product being imported.

Does a single CM/L licence cover all fastener types and sizes under this HSN?

No. Each CM/L licence is scope-specific by Indian Standard, fastener type, size range, property class, and manufacturing facility; fasteners outside the licensed scope — even from the same manufacturer — are not covered and are liable to detention.
