Compliance steps

1
Identify the exact product type in the consignment — stainless steel butt hinges (IS 12817:2020), steel butt hinges (IS 1341:2018), non-ferrous butt hinges (IS 205:1992), tee and strap hinges (IS 206:2010), parliament hinges (IS 362:1991), continuous/piano hinges (IS 3818:1992), steel back flap hinges (IS 3843:1995), double-acting spring hinges (IS 453:1993), or cabinet hinges (IS 18297:2023) — before procuring from the supplier.

2
Verify the foreign manufacturer's BIS CM/L licence number on the BIS online register against the specific IS standard governing the product type. The CM/L must cover the exact hinge or tower-bolt specification, material class, and manufacturing facility before the purchase order is placed.

3
If the consignment includes tower bolts, confirm the applicable standard: IS 204 (Part 1):1991 for ferrous tower bolts, IS 204 (Part 2):1992 for non-ferrous tower bolts, or IS 15833:2009 for stainless steel tower bolts. Each material class requires a separate CM/L covering that specific IS.

4
Ensure every article in the consignment bears the ISI mark and the supplier's CM/L number in accordance with Scheme-I of Schedule-II to the Bureau of Indian Standards (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself; packaging-only marking does not satisfy the requirement.

5
Quote the supplier's BIS CM/L number and the applicable IS reference on the bill of entry. Customs verifies CM/L validity and product-scope coverage in real time against the BIS register; an absent, expired, or scope-mismatched CM/L triggers consignment detention.

A word of counsel

The most consequential error on this tariff line is importing under a single CM/L that covers one hinge specification while the consignment contains multiple product types governed by different Indian Standards — for example, combining stainless steel butt hinges (IS 12817:2020) and cabinet hinges (IS 18297:2023) under a CM/L issued only for the former. Customs may examine the consignment at line-item level, and any article without a matching licensed CM/L is liable to detention, re-export, or confiscation regardless of the remaining articles being compliant. Verify that the supplier holds a separate, current CM/L for each IS standard applicable to every product type in the shipment.

Frequently asked

Does HSN 8302 41 90 require BIS certification?

Yes. Articles falling within this tariff line — including hinges and tower bolts suitable for buildings — require a Bureau of Indian Standards CM/L licence under the ISI Mark Scheme against the applicable Indian Standard, with effect from 01 July 2025 for hinges under S.O. 1368(E) and from the enforcement date of S.O. 2771(E) for tower bolts.

Which Indian Standard applies to my product under this HSN?

The applicable IS depends on the product type and material: IS 12817:2020 (stainless steel butt hinges), IS 1341:2018 (steel butt hinges), IS 205:1992 (non-ferrous butt hinges), IS 206:2010 (tee and strap hinges), IS 362:1991 (parliament hinges), IS 3818:1992 (continuous/piano hinges), IS 3843:1995 (steel back flap hinges), IS 453:1993 (double-acting spring hinges), IS 18297:2023 (cabinet hinges), IS 204 (Part 1):1991 or IS 204 (Part 2):1992 or IS 15833:2009 for tower bolts by material.

Does the Hinges (Quality Control) Order, 2025 cover tower bolts as well?

No. Tower bolts under this HSN are regulated separately by the Bolts, Nuts and Fasteners (Quality Control) Order, 2024 under S.O. 2771(E). A consignment mixing hinges and tower bolts must demonstrate CM/L compliance under both Quality Control Orders.

Does a single CM/L licence cover all hinge types and materials from the same manufacturer?

No. A CM/L is issued against a specific IS standard covering a defined product type and manufacturing facility; different hinge specifications — for example, stainless steel butt hinges under IS 12817:2020 versus cabinet hinges under IS 18297:2023 — require separate CM/L licences even from the same supplier.
