Dielectric of paper or plastics

Fixed capacitors with paper or plastics dielectric (AC motor, power, shunt capacitors)

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 2993

HSN 8532 25 00 (fixed capacitors with dielectric of paper or plastics) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 2993, IS 13340, or IS 13585 (Part 1) is mandatory under the ISI Mark Scheme with effect from 01 August 2017, by virtue of the Electrical Capacitors (Quality Control) Order, 2017. No separate customs-clearance overlay applies beyond the BIS obligation.

Compliance steps

1
Identify which Indian Standard governs the specific capacitor variant being imported: IS 2993 for AC motor capacitors, IS 13340 for self-healing power capacitors for AC systems up to 650 V, or IS 13585 (Part 1) for non-self-healing shunt power capacitors for AC systems up to 1000 V. The CM/L licence must correspond to the correct standard for the product.

2
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the applicable IS (2993, 13340, or 13585 Part 1). Verify the CM/L number, licensed product scope, rated voltage range, and licensed manufacturing facility on the BIS online register before placing the purchase order.

3
Ensure each capacitor bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself; packaging-only marking does not satisfy the statutory requirement.

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

A word of counsel

The single most common error on this tariff line is treating the three applicable standards as interchangeable and sourcing a CM/L licence against IS 2993 (AC motor capacitors) to cover a shipment of self-healing power capacitors that should be licensed under IS 13340. Each standard maps to a distinct capacitor type and voltage regime; a CM/L licence issued against one standard provides no statutory cover for product falling within another, and customs will detain the consignment on a standard-to-product mismatch at port regardless of whether the supplier otherwise holds a valid BIS licence.

Frequently asked

Does HSN 8532 25 00 require BIS certification?

Yes. Fixed capacitors with dielectric of paper or plastics are subject to the Electrical Capacitors (Quality Control) Order, 2017 under the ISI Mark Scheme; import is permitted only from manufacturers holding a current BIS CM/L licence against IS 2993, IS 13340, or IS 13585 (Part 1), as applicable, with effect from 01 August 2017.

Which Indian Standard applies to a specific capacitor variant under this HSN?

IS 2993 governs AC motor capacitors; IS 13340 governs self-healing power capacitors for AC systems with rated voltage up to 650 V; IS 13585 (Part 1) governs non-self-healing shunt power capacitors for AC systems with rated voltage up to and including 1000 V.

Can a single CM/L licence cover all three capacitor types within a single consignment?

No. A CM/L licence is standard-specific and scope-specific; a manufacturer must hold separate CM/L licences against each applicable IS for each capacitor type and voltage range. A consignment mixing capacitor types requires verification of a corresponding CM/L for each type.

Is the CM/L licence facility-specific?

Yes. The CM/L licence is tied to the licensed manufacturing facility; capacitors produced at a plant not covered by the licence are outside scope, and customs detains consignments where the facility on the shipping documents does not match the licensed facility on the BIS register.
