BIS QCO APPLICABLE · ISI MARK SCHEME · IS 1363 · SIMS OVERLAY

HSN 7318 19 00 (other threaded fasteners of iron or steel) is covered by two Bureau of Indian Standards Quality Control Orders: the Bolts, Nuts and Fasteners QCO 2024 (S.O. 2771(E)) and the Cross Recessed Screws QCO 2025 (S.O. 3927(E)). Conformity to the applicable Indian Standard is mandatory under the ISI Mark Scheme, with general-category enforcement from 01 November 2025 and staggered dates for small and micro enterprises. Steel Import Monitoring System registration administered by the Directorate General of Foreign Trade applies as a separate customs-clearance overlay.

Compliance steps

1
Identify the specific fastener type and map it to the applicable Indian Standard before placing the purchase order. The two QCOs collectively cover IS 1363 (parts 1–3), IS 1364 (parts 1–2), IS 3757, IS 4621, IS 5187, IS 6623, IS 7483, IS 7485, IS 7486, IS 10238, IS 12427, IS 15833, IS 18471, IS 18476, IS 18480, IS 18507, IS 18508, and IS 18509.

2
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the relevant IS number, size range, property class, and manufacturing facility. Verify the CM/L number and licensed product scope on the BIS online register before shipment.
Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018 · S.O. 2771(E) · S.O. 3927(E)
3
Ensure each fastener bears the ISI mark and the supplier's CM/L number. Marking must appear on the product or its smallest commercial packaging unit traceable to the licensed manufacturing facility, not on the outer carton alone.

4
Register the consignment on the Steel Import Monitoring System portal before arrival; fee ₹500, registration valid for 75 days. The minimum 15-day advance registration requirement has been abolished, but the registration must be current on the date of arrival.

5
Verify the CIF-value threshold before import: the import policy for screws under HSN 7318 19 00 is prohibited unless the CIF value is ₹129 or above per kg. Confirm compliance with policy conditions 2 and 3 of Chapter 73, and quote the BIS CM/L number and SIMS registration number on the bill of entry.

A word of counsel

The most common error on this tariff line is presenting a single CM/L licence as covering all fastener variants in a mixed consignment. A CM/L is IS-number-specific, part-specific, size-range-specific, and property-class-specific; a licence against IS 1363 (Part 1) for M5–M64 hexagon head bolts does not cover cross recessed screws governed by IS 18471 or IS 18480, even if both products travel on the same invoice. Customs verifies scope at the line-item level, and a single scope mismatch triggers detention of the entire consignment pending re-export or confiscation.

Frequently asked

Does HSN 7318 19 00 require BIS certification?

Yes. Threaded fasteners under this tariff line are subject to the ISI Mark Scheme under the Bolts, Nuts and Fasteners QCO 2024 (S.O. 2771(E)) and the Cross Recessed Screws QCO 2025 (S.O. 3927(E)); import is permitted only from manufacturers holding a current BIS CM/L licence against the applicable Indian Standard.

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, and the registration must be current on the date of arrival.

Are there staggered enforcement dates for small and micro enterprises under the Cross Recessed Screws QCO 2025?

Yes. General enforcement began 01 November 2025; small enterprises must comply from 01 February 2026; micro enterprises from 01 May 2026. Exemptions are set out in paragraph 2 of S.O. 3927(E) dated 27-08-2025.

Does one CM/L licence cover all fastener types and sizes in a shipment?

No. Each CM/L is specific to the IS number, part, size range, property class, and licensed manufacturing facility; mixed consignments require verification of a separate CM/L for each fastener variant against its governing Indian Standard.
