Screw hooks and screw rings

Screw hooks and screw rings of iron or steel

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

HSN 7318 13 00 (screw hooks and screw rings of iron or steel) is covered by two Bureau of Indian Standards Quality Control Orders. Conformity to the applicable Indian Standards is mandatory under the ISI Mark Scheme — the Bolts, Nuts and Fasteners (Quality Control) Order, 2024 (S.O. 2771(E)) and the Cross Recessed Screws (Quality Control) Order, 2025 (S.O. 3927(E)) govern this tariff line, with effect from 27 August 2025 for the latter. Steel Import Monitoring System registration administered by the Directorate General of Foreign Trade applies as a separate customs-clearance overlay.

Compliance steps

1
Determine which Indian Standard governs the specific screw hook or screw ring being imported — IS 12427:2001 for coach screws and screw hooks, IS 18509:2023 for cross-recessed wood screws and screw rings, or the relevant IS 1363/IS 1364 part for hexagon-head variants. Verify the supplier's BIS CM/L licence number covers the exact standard, part, and size range on the BIS online register before placing the purchase order.

2
Ensure every product 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 mark must appear on the product itself; marking on packaging only does not satisfy the statutory requirement.

3
Register the consignment on the Steel Import Monitoring System portal before arrival; the advance minimum-15-day requirement has been abolished. Fee ₹500, automatic registration valid for 75 days. The registration must be live on the date the consignment arrives.

4
Verify that the CIF value of the consignment is ₹129 per kg or above before import. The import policy for HSN 7318 13 00 is otherwise prohibited; the free-import window opens only at or above this CIF threshold, subject to policy conditions 2 and 3 of Chapter 73.
S.O. 55(E) dated 03-01-2024 · DGFT Notification 55/2023 dated 03-01-2024
5
Ensure compliance with Central Board of Indirect Taxes and Customs Instruction 01/2026-Customs dated 17-01-2026 and the Ministry of Steel Order dated 13-01-2026. Quote the BIS CM/L number and SIMS registration number on the bill of entry; customs verifies both in real time.

A word of counsel

The most common error on this tariff line is treating IS 1363 or IS 1364 as the universal applicable standard for all screw hooks and screw rings, while overlooking IS 18509:2023 and IS 12427:2001, which specifically govern screw hooks and screw rings under the Cross Recessed Screws QCO 2025. A CM/L licence against IS 1363 (hexagon head bolts) does not cover screw hooks supplied under IS 18509 or IS 12427; a scope mismatch at the border triggers detention regardless of whether the licence itself is current and valid.

Frequently asked

Does HSN 7318 13 00 require BIS certification?

Yes. Screw hooks and screw rings must conform to the applicable Indian Standard and bear the ISI mark under a CM/L licence issued by the Bureau of Indian Standards, mandatory under the Bolts, Nuts and Fasteners (Quality Control) Order, 2024 and the Cross Recessed Screws (Quality Control) Order, 2025.

Is SIMS registration required separately from BIS QCO compliance?

Yes. Steel Import Monitoring System registration is administered by the Directorate General of Foreign Trade independently of the BIS QCO obligation. The ₹500 fee applies and the automatic registration number is valid for 75 days from issue.

What is the phased enforcement timeline under S.O. 3927(E)?

The Cross Recessed Screws QCO 2025 takes effect from 27 August 2025 as the date of publication; general importers (other than micro and small enterprises) must comply from 01 November 2025, small enterprises from 01 February 2026, and micro enterprises from 01 May 2026.

Does a single CM/L licence cover all screw hook and screw ring variants from one manufacturer?

No. A CM/L licence is standard-specific and scope-specific by IS number, part, size range, and manufacturing facility. Screw hooks or rings outside the licensed IS number or size range, or from an unlicensed plant, are not covered and face detention at port.
