BIS QCO APPLICABLE · ISI MARK SCHEME · IS 1659

HSN 4411 94 21 (insulation board of a density not exceeding 0.5 g/cm³) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 3513 and the co-applicable wood-based-board standards is mandatory under the ISI Mark Scheme with effect from 11 February 2025, by virtue of the Wood Based Boards (Quality Control) Order, 2024. Phytosanitary Certificate upload to e-Sanchit applies as a separate customs-clearance overlay.

Compliance steps

1
Verify the foreign manufacturer's BIS CM/L licence number on the BIS online register against IS 3513 (covering insulation boards and hardboards from wood and lignocellulosic fibres) before placing the purchase order. Confirm the licensed scope covers the density grade, thickness range, and manufacturing facility of the consignment.

2
Confirm whether the consignment also triggers IS 3087:2005, IS 12406:2021, IS 1659:2004, IS 12823:2015, or IS 3097:2006 based on the board's density, construction, and surface treatment. Each standard requires a separate, current CM/L; a single licence does not automatically cover all co-listed standards.

3
Ensure every board bears the ISI mark and the supplier's CM/L number per Scheme-I of the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product or, where size prevents it, on each unit of packaging in a manner traceable to the individual board.

4
Upload the Phytosanitary Certificate (document code 851000) to e-Sanchit before the consignment arrives. The proper officer must verify its presence prior to granting out-of-charge; absence blocks clearance irrespective of BIS CM/L status.

5
Note the staggered enforcement dates: the BIS QCO obligation under S.O. 1307(E) applies to all importers from 11-02-2025, but small enterprises had until 11-05-2025 and micro enterprises until 11-08-2025. Verify the applicable date against the enterprise size classification for any retrospective clearance queries.

A word of counsel

The most consequential error on this tariff line is importing insulation board on the assumption that a single CM/L against any one co-listed standard satisfies all BIS obligations across the entire wood-based-boards cluster. IS 3513 governs insulation board specifically, but density, surface treatment, and core construction can simultaneously attract IS 3087, IS 12406, or IS 3097 — each requiring its own current CM/L. Consignments detained at port for standard-scope mismatch accrue demurrage and ground rent while the importer pursues either re-export or a retrospective testing-and-licensing cycle.

Frequently asked

Does HSN 4411 94 21 require BIS certification?

Yes. Insulation board at this density is mandatorily covered under the ISI Mark Scheme against IS 3513 with effect from 11 February 2025, under the Wood Based Boards (Quality Control) Order, 2024. Import is permitted only from a manufacturer holding a current BIS CM/L licence covering the specific product scope.

Can one CM/L licence cover all the wood-based-board standards listed for this HSN?

No. IS 3513, IS 3087, IS 12406, IS 1659, IS 12823, and IS 3097 are distinct standards; each requires a separate CM/L licence. The applicable standard depends on the board's density, construction, and intended use.

Do small and micro enterprises have different compliance deadlines?

Yes. Under S.O. 1307(E), the mandatory date was 11-02-2025 for all importers generally; small enterprises had a deferred date of 11-05-2025 and micro enterprises 11-08-2025. These deferrals apply to enterprise classification on the date of import.

Is the Phytosanitary Certificate requirement separate from the BIS QCO obligation?

Yes. The Phytosanitary Certificate (e-Sanchit document code 851000) is an independent customs-clearance requirement. The proper officer must confirm its upload before granting out-of-charge, and its absence will block clearance regardless of the BIS CM/L status.
