Tantalum

Fixed tantalum capacitors for electrical circuits

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 2993

HSN 8532 21 00 (fixed tantalum capacitors) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 2993, IS 13340, or IS 13585 (Part 1) — as applicable to the specific capacitor type — is mandatory under the ISI Mark Scheme with effect from 01 August 2017, pursuant to the Electrical Capacitors (Quality Control) Order, 2017. No separate customs-clearance overlay applies beyond the BIS obligation.

Compliance steps

1
Identify the precise capacitor sub-type before sourcing: IS 2993 governs AC motor capacitors; IS 13340 governs self-healing power capacitors for AC systems up to 650 V; IS 13585 (Part 1) governs non-self-healing shunt power capacitors for AC systems up to 1000 V. Source only from a Bureau of Indian Standards CM/L-licensed manufacturer whose licence explicitly covers the applicable standard and the relevant voltage and specification range.

2
Verify the supplier's BIS CM/L licence number on the BIS online register before placing the purchase order. Confirm that the licensed product scope covers the exact capacitor type, voltage rating, and manufacturing facility being supplied.

3
Ensure every unit in the consignment bears the ISI mark and the supplier's CM/L number in accordance with Scheme-I of the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself; packaging-only marking is insufficient.

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; a licence that is absent, expired, or whose product scope does not cover the consignment's capacitor type and voltage rating triggers detention of the consignment.

A word of counsel

The single most common error on this tariff line is supplying a single CM/L licence number without confirming that it covers the specific capacitor sub-type and voltage class being imported. IS 2993, IS 13340, and IS 13585 (Part 1) are distinct standards with non-overlapping scopes; a CM/L issued against IS 2993 for AC motor capacitors does not authorise import of self-healing power capacitors governed by IS 13340, and customs detention follows when the consignment product specification falls outside the licensed scope.

Frequently asked

Does HSN 8532 21 00 require BIS certification?

Yes. Fixed tantalum capacitors classified under this tariff line require Bureau of Indian Standards CM/L certification under the ISI Mark Scheme, with effect from 01 August 2017, pursuant to the Electrical Capacitors (Quality Control) Order, 2017.

Which Indian Standard applies to a given tantalum capacitor import?

IS 2993 applies to AC motor capacitors; IS 13340 applies to self-healing power capacitors for AC systems rated up to 650 V; IS 13585 (Part 1) applies to non-self-healing shunt power capacitors for AC systems rated up to 1000 V. The applicable standard is determined by the technical specification of the product, not by the importer's preference.

Does one CM/L licence cover all three capacitor types under this HSN?

No. A CM/L licence is standard-specific and product-scope-specific; a licence against IS 2993 does not cover capacitors within the scope of IS 13340 or IS 13585 (Part 1). Separate licences are required where a supplier manufactures across sub-types.

Is the CM/L licence facility-specific?

Yes. A BIS CM/L licence is tied to the specific manufacturing facility declared at the time of licensing; capacitors produced at an unlicensed plant, even under the same brand or group entity, are not covered by the licence.
