Compliance steps

1
Verify the foreign manufacturer holds a current BIS CM/L licence against the specific IS applicable to the product: IS 710:2010 for marine plywood, IS 709 for aircraft plywood (hull/deck/structural aerospace panels), or IS 4859 for aircraft shuttering plywood. The CM/L must cover the licensed manufacturing facility and the exact panel specification being imported.

2
Ensure each panel bears the ISI mark and the supplier's CM/L number in accordance with the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the panel or its wrapping in a manner traceable to the licensed lot — marking on the outer pallet alone is insufficient.

3
Upload the Phytosanitary Certificate (document code 851000) in e-Sanchit before the bill of entry is filed. The proper officer is required to verify its upload before granting out-of-charge; absence of the PSC in the e-Sanchit portal stalls customs clearance regardless of BIS compliance.

4
Quote the supplier's BIS CM/L number on the bill of entry and confirm the IS scope aligns with the tariff description. Per the supplementary notes to Chapter 44, marine plywood must conform to IS 710 and aircraft plywood to IS 709 and IS 4859; a CM/L issued against IS 303 (general-purpose plywood) does not satisfy this obligation.

5
If the manufacturer is an Indian small enterprise, the deferred enforcement date is 28 May 2025; for micro enterprises, 28 August 2025. Confirm the enterprise classification of the manufacturer before relying on any deferred-date exemption, as the standard enforcement date of 28 February 2025 applies to all other suppliers.

A word of counsel

The single most common error on this tariff line is presenting a BIS CM/L licence issued against IS 303 (general-purpose plywood) or IS 4990 (concrete-shuttering plywood) as satisfying the marine or aircraft plywood obligation. The Chapter 44 supplementary notes are explicit: marine plywood must conform to IS 710 and aircraft plywood to IS 709 and IS 4859. A scope-mismatched CM/L triggers detention at port and exposes the importer to confiscation proceedings under the BIS Act, 2016, irrespective of the panel's actual physical quality.

Frequently asked

Does HSN 4412 33 30 require BIS certification?

Yes. Marine and aircraft plywood under this tariff line must bear the ISI mark under a BIS CM/L licence — IS 710:2010 for marine plywood and IS 709 or IS 4859 for aircraft plywood — with effect from 28 February 2025 under the Plywood and Wooden Flush Door Shutters Quality Control Order, 2024.

Which Indian Standard applies to marine plywood and which to aircraft plywood?

Per the supplementary notes to Chapter 44, marine plywood must conform to IS 710 and aircraft plywood to IS 709 and IS 4859. A CM/L licence under any other IS does not satisfy the obligation for these specific product descriptions.

Do deferred enforcement dates apply to foreign manufacturers of marine or aircraft plywood?

The deferred dates (28 May 2025 for small enterprises; 28 August 2025 for micro enterprises) apply based on the enterprise classification of the manufacturer. The standard enforcement date of 28 February 2025 applies to all other manufacturers; an importer relying on a deferred date must document the supplier's enterprise classification.

Does a single CM/L licence cover all plywood grades from the same manufacturing facility?

No. The CM/L is IS-specific and facility-specific; a licence for IS 710 (marine) does not cover IS 709 or IS 4859 (aircraft) grades, and panels manufactured at an unlicensed plant are not covered regardless of the group company's licence.
