Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 2835:1987 for flat transparent sheet glass. Verify the supplier's CM/L number, licensed product scope, and licensed manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure each sheet or batch bears the ISI mark and the supplier's CM/L number under licence per Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product or on primary packaging in a manner traceable to the licensed batch.

3
Obtain from the supplier the test reports demonstrating conformity to IS 2835:1987 parameters covering dimensions, thickness tolerances, and optical quality. Retain these with the import documentation for customs verification.

4
Quote the supplier's BIS CM/L number on the bill of entry. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or scope-mismatched licence triggers consignment detention, demurrage, and potential re-export or confiscation.

A word of counsel

The most common error on this tariff line is importing unworked drawn or blown sheet glass under HSN 7004 90 99 from a supplier whose CM/L licence is scoped to a different glass product family — most often toughened or laminated safety glass classified under heading 7007. IS 2835:1987 covers flat transparent sheet glass as a base material; a CM/L held against a safety-glass standard does not satisfy the QCO obligation here, and customs will detain the consignment on a scope mismatch regardless of the supplier's overall BIS registration history.

Frequently asked

Does HSN 7004 90 99 require BIS certification?

Yes. Flat transparent sheet glass under this tariff line must conform to IS 2835:1987 under the ISI Mark Scheme; import is permitted only from manufacturers holding a current BIS CM/L licence scoped to IS 2835:1987, with effect from 07 October 2021.

Does a CM/L licence for safety glass or toughened glass under heading 7007 satisfy the IS 2835:1987 requirement for HSN 7004 90 99?

No. IS 2835:1987 governs flat transparent sheet glass as a base material; a CM/L held against a different standard or product family does not cover this tariff line, and customs will reject the consignment on a scope mismatch.

When did the IS 2835:1987 QCO obligation come into force for this HSN?

The Flat Transparent Sheet Glass (Quality Control) Order, 2021, notified under S.O. 4144(E) dated 07-10-2021, brought the obligation into force on 07 October 2021.

Does a single CM/L licence cover all sheet sizes and thicknesses from the same manufacturing facility?

No. The CM/L is scope-specific by product specification and manufacturing facility; sheet dimensions or thicknesses outside the licensed scope, or production from an unlicensed plant, are not covered.
