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

HSN 7318 14 00 (self-tapping screws of iron or steel) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to the applicable Indian Standards — principally IS 18480, IS 18471, IS 7483, IS 7485, IS 7486, and related fastener standards — is mandatory under the ISI Mark Scheme with effect from 27 August 2025 under the Cross Recessed Screws Quality Control Order, 2025. Steel Import Monitoring System registration administered by the Directorate General of Foreign Trade, and a price-floor import policy condition, apply as separate customs-clearance overlays.

Compliance steps
  1. 1
    Verify the foreign manufacturer's BIS CM/L licence on the BIS online register against the specific Indian Standard covering the self-tapping screw variant being imported — IS 18480 (cross-recessed tapping screws), IS 18471 (drilling screws with tapping thread), IS 7483 (pan-head tapping screws), IS 7485 (countersunk-head tapping screws), IS 7486 (raised countersunk), IS 18507 (drywall screws), IS 18508 (chipboard screws), or IS 18509 (wood screws). Confirm the licence covers the specific head form, drive recess type, and manufacturing facility.

  2. 2
    Confirm the applicable enforcement date for the supplier's enterprise category: general enterprises from 01-11-2025, small enterprises from 01-02-2026, and micro enterprises from 01-05-2026. Consignments shipped before the applicable date but arriving after it must bear ISI marking; verify the supplier's CM/L was valid on the date of manufacture.

  3. 3
    Ensure every self-tapping screw in the consignment bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product or, where product size makes direct marking impractical, on the smallest unit packaging traceable to the batch.

  4. 4
    Register the consignment on the Steel Import Monitoring System portal, paying the ₹500 registration fee, no earlier than 60 days before the expected date of arrival. The automatic SIMS registration number is valid for 75 days; it must remain within validity on the date of arrival. The minimum 15-day advance registration requirement has been abolished.

  5. 5
    Confirm the CIF value of the consignment meets or exceeds ₹129 per kg before filing the bill of entry. Import of self-tapping screws under HSN 7318 14 00 is prohibited unless the CIF value is ₹129 per kg or above, subject to policy conditions 2 and 3 of Chapter 73. Quote the BIS CM/L number and the SIMS registration number on the bill of entry.

A word of counsel

The single most common error on this tariff line is sourcing from a CM/L-licensed supplier whose licence covers the fastener heading broadly but does not extend to the specific IS standard governing the imported screw variant — for example, a licence issued against IS 18480 (Part 1) for pan-head tapping screws does not cover IS 18480 (Part 3) raised countersunk oval-head screws, let alone IS 18471 drilling screws or IS 18509 wood screws. Customs verification is model-specific; a scope mismatch between the shipped product and the licensed standard triggers consignment detention even where the CM/L itself is current and the SIMS registration is valid. Map every screw variant in the purchase order to its governing IS part before confirming the supplier.

Frequently asked
Does HSN 7318 14 00 require BIS certification?
Yes. Self-tapping screws of iron or steel require ISI Mark Scheme certification under the Cross Recessed Screws Quality Control Order, 2025. The CM/L licence must be held against the specific Indian Standard governing the screw variant imported, with effect from 27 August 2025 per S.O. 3927(E).
Is there a price-floor restriction on importing self-tapping screws?
Yes. Import of screws under HSN 7318 14 00 is prohibited unless the CIF value is ₹129 per kg or above, per S.O. 55(E) and DGFT Notification 55/2023, both dated 03 January 2024. The BIS QCO obligation applies in addition to, and independently of, this price-floor condition.
Do different enterprise categories have different BIS QCO enforcement dates?
Yes. General enterprises must comply from 01-11-2025, small enterprises from 01-02-2026, and micro enterprises from 01-05-2026, per S.O. 3927(E) dated 27-08-2025. Exemptions for specific cases are set out in paragraph 2 of that statutory order.
Does a single CM/L licence cover all self-tapping screw variants from the same manufacturer?
No. The CM/L is issued against a specific Indian Standard and product scope; a licence against IS 18480 (Part 1) pan-head screws does not cover IS 18471 drilling screws, IS 18507 drywall screws, or IS 18509 wood screws. Each variant must be within the licensed scope and manufacturing facility covered by the CM/L.
