Machine screws

Machine screws of iron or steel (coach screws, hexagon and cross-recessed types)

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

HSN 7318 11 10 (machine screws 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 Standards — spanning IS 1363, IS 1364, IS 12427, IS 18471, IS 18480, IS 18507, IS 18508, IS 18509, and related standards — is mandatory under the ISI Mark Scheme, with the Cross Recessed Screws QCO effective from 27 August 2025. Steel Import Monitoring System registration administered by the Directorate General of Foreign Trade and a CIF-value-floor import-policy condition apply as separate customs-clearance overlays.

Compliance steps

1
Identify which Indian Standard governs the specific screw type being imported — IS 1363 (product grade C hexagon head, M5–M64), IS 1364 (product grades A and B, M1.6–M64), IS 18480 (cross-recessed tapping screws), IS 18507 (drywall screws), IS 18508 (chipboard screws), IS 18509 (countersunk head wood screws), or other applicable standards under the two QCOs. Verify the supplier's BIS CM/L licence covers that specific standard, size range, and licensed manufacturing facility on the BIS online register before placing the purchase order.

2
Confirm the phased enforcement schedule for the Cross Recessed Screws QCO 2025: general importers from 01-11-2025, small enterprises from 01-02-2026, and micro enterprises from 01-05-2026. For enterprises claiming micro or small status, retain documented Udyam registration as evidence of the applicable phase.

3
Ensure every screw in the consignment bears the ISI mark and the supplier's CM/L number per Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself; marking only on packaging does not satisfy the QCO requirement.

4
Verify that the CIF value of the consignment is ₹129 or above per kilogram. Imports of screws under ITC(HS) 7318 11 10 are otherwise prohibited; the free-import channel is conditional on meeting this CIF-value floor and compliance with policy conditions 2 and 3 of Chapter 73.

5
Register the consignment on the Steel Import Monitoring System portal before the expected date of arrival — the minimum 15-day advance-registration requirement has been abolished, but advance registration remains mandatory. Fee ₹500, SIMS registration valid for 75 days. Quote the SIMS registration number and the BIS CM/L number on the bill of entry.

A word of counsel

The single most consequential oversight on this tariff line is treating the two QCOs as one obligation with one IS number. The Bolts, Nuts and Fasteners QCO 2024 and the Cross Recessed Screws QCO 2025 carry distinct IS standards, distinct scope boundaries, and distinct enforcement dates; a CM/L licence covering IS 1363 does not cover IS 18480 or IS 18507 cross-recessed types. Importers who verify only the primary IS against the BIS register — and miss a mismatched or absent licence for the specific screw sub-type in the consignment — face detention and re-export at port even where the SIMS registration and CIF-value floor are fully satisfied.

Frequently asked

Does HSN 7318 11 10 require BIS certification?

Yes. Machine screws under this tariff line require conformity to the applicable Indian Standard and a current BIS CM/L licence under the ISI Mark Scheme, by virtue of the Bolts, Nuts and Fasteners QCO 2024 (S.O. 2771(E)) and, for cross-recessed types, the Cross Recessed Screws QCO 2025 (S.O. 3927(E)).

Is there a CIF-value floor that governs import of screws under this HSN?

Yes. Imports of screws under ITC(HS) 7318 11 10 are prohibited unless the CIF value is ₹129 or above per kilogram, per S.O. 55(E) and DGFT Notification 55/2023 both dated 03-01-2024. The BIS QCO obligation is additional and is not waived by the CIF condition.

Do micro and small enterprises have different compliance dates under the Cross Recessed Screws QCO 2025?

Yes. The phased dates under S.O. 3927(E) are: general importers from 01-11-2025, small enterprises from 01-02-2026, and micro enterprises from 01-05-2026. Enterprises claiming a later date must retain Udyam registration documentation as evidence of their enterprise classification.

Does a single CM/L licence cover all screw types and size ranges in a mixed consignment?

No. The CM/L is specific to the Indian Standard, product variant, size range, and manufacturing facility; a licence against IS 1363 does not cover cross-recessed screws governed by IS 18480, IS 18507, or IS 18509, and each out-of-scope item triggers a compliance breach.
