Mounted piezo-electric crystals

Mounted piezo-electric crystals for oscillators and electronic resonators

BIS QCO APPLICABLE · CRS SCHEME · IS 14286

HSN 8541 60 00 (Mounted piezo-electric crystals) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 14286 (Part 1):2023 and IS/IEC 61730:2016 series is mandatory under the Compulsory Registration Scheme with effect from 27 July 2025, by virtue of the Solar Systems, Devices and Components Goods Order, 2025. No separate customs-clearance overlay beyond the BIS obligation is recorded for this tariff line.

Compliance steps

1
Verify the foreign manufacturer's Bureau of Indian Standards Compulsory Registration Scheme R-number on the BIS portal before placing the purchase order. The R-number must be registered against the applicable IS 14286 (Part 1):2023 or IS/IEC 61730:2016 series and must be current on the bill of lading date.

2
Confirm the applicable standard for the module technology: IS 14286 (Part 1):2023 series applies to crystalline-silicon (Si wafer-based) terrestrial PV modules; IS/IEC 61730-1:2016 and IS/IEC 61730-2:2016 apply to thin-film terrestrial PV modules (CdTe, a-Si, Cu(In,Ga)(S,Se)2). The R-number must match the specific module technology being imported.

3
Ensure each module or assembly bears the BIS standard mark under licence from the Bureau as per Scheme-II of the BIS (Conformity Assessment) Regulations, 2018. The standard mark must appear on the product itself; marking on packaging alone does not satisfy the statutory requirement.

4
Quote the supplier's BIS R-number, the applicable IS reference, and the CRS registration model code on the bill of entry. Customs verifies the R-number in real time against the BIS portal; an absent, expired, or technology-mismatched registration triggers consignment detention and potential re-export.

A word of counsel

The most consequential error on this tariff line is the classification mismatch between product description and applicable standard: HSN 8541 60 00 carries the product descriptor 'Mounted piezo-electric crystals', yet the QCO operative under S.O. 492(E) mandates compliance against IS 14286 (Part 1):2023 and IS/IEC 61730 series — standards written for crystalline-silicon and thin-film terrestrial photovoltaic modules, not electronic oscillator crystals. An importer of genuine piezo-electric crystals used in oscillators or resonators who nonetheless imports under this HSN faces a BIS CRS obligation tied to PV-module standards, and should seek a formal tariff ruling before shipment to avoid detention on a standard that does not technically apply to the goods.

Frequently asked

Does HSN 8541 60 00 require BIS certification?

Yes. Goods under HSN 8541 60 00 require Bureau of Indian Standards registration under the Compulsory Registration Scheme, with effect from 27 July 2025, pursuant to the Solar Systems, Devices and Components Goods Order, 2025 notified by S.O. 492(E).

Which Indian Standard applies to crystalline-silicon modules versus thin-film modules under this HSN?

IS 14286 (Part 1):2023 series applies to crystalline-silicon (Si wafer-based) terrestrial PV modules. IS/IEC 61730-1:2016 and IS/IEC 61730-2:2016 apply to thin-film modules (CdTe, a-Si, Cu(In,Ga)(S,Se)2). The BIS R-number must be registered against the standard that matches the module technology.

Why do photovoltaic module standards apply to a tariff line described as mounted piezo-electric crystals?

The Solar Systems, Devices and Components Goods Order, 2025 maps IS 14286 and IS/IEC 61730 to this CTI as recorded in the BIS QCO schedule. Importers of products that are genuinely piezo-electric oscillator crystals should obtain a formal tariff classification ruling before shipment.

Does a single CRS R-number cover all module variants and technology types from one manufacturer?

No. The R-number is model-specific and technology-specific; crystalline-silicon and thin-film variants each require separate registration, and modules outside the registered model code are not covered by the existing R-number.
