Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 2403:2014 for precision roller and bush chains. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility address on the BIS online register before placing the purchase order.

2
Confirm the phased enforcement category that applies to your supplier: general enterprises from 01-10-2024, small enterprises from 01-01-2025, and micro enterprises from 01-04-2025. A micro or small enterprise supplier must hold a current CM/L on the applicable date of the shipment.

3
Ensure every roller chain 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 standard mark must appear on the product or its traceable packaging unit, not solely on commercial invoices.

5
Verify that the CIF value of the consignment meets or exceeds ₹235 per kilogram. Import of roller chains and parts with a CIF value below ₹235 per kilogram is restricted; consignments below this threshold require specific authorisation before the bill of entry is filed.

A word of counsel

The most common error on this tariff line is treating the enforcement date of S.O. 2174(E) — 03 June 2024 — as the single operative date for all importers, while overlooking the phased entry points for small and micro enterprises. An importer sourcing from a supplier that qualifies as a micro enterprise under the Micro, Small and Medium Enterprises Development Act, 2006 faces a different BIS CM/L deadline (01-04-2025) than a general enterprise supplier (01-10-2024); customs applies the enterprise-category-specific date, not the gazette date, when assessing whether the marking obligation has crystallised.

Frequently asked

Does HSN 7315 11 00 require BIS certification?

Yes. Precision roller and bush chains under this tariff line must conform to IS 2403:2014 and bear the ISI mark under a CM/L licence, by virtue of the Precision Roller and Bush Chains, Attachments and Associated Chains Sprockets (Quality Control) Order, 2024, notified as S.O. 2174(E).

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 arrival date.

Do the phased enforcement dates apply to the importer or to the foreign manufacturer?

The phased dates apply to the enterprise category of the manufacturer: general enterprises from 01-10-2024, small enterprises from 01-01-2025, and micro enterprises from 01-04-2025. The importer must verify which category covers the foreign supplier and confirm the CM/L was current on the applicable date.

Does a single CM/L licence cover all roller chain sizes and bush chain variants from one manufacturer?

No. A CM/L licence is scope-specific by chain type, pitch, and manufacturing facility; variants outside the licensed scope or produced at an unlicensed plant are not covered, and customs detains the consignment on a scope mismatch.
