Fixed electrical capacitors for AC power systems (motor, self-healing, non-self-healing types)

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 2993

HSN 8532 29 90 (fixed electrical capacitors for AC power systems) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 2993, IS 13340, or IS 13585 (Part 1) — depending on capacitor type — is mandatory under the ISI Mark Scheme with effect from 1 August 2017, by virtue of the Electrical Capacitors (Quality Control) Order, 2017. No additional customs-clearance overlay applies beyond the BIS obligation.

Compliance steps

1
Identify the capacitor 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 BIS CM/L-licensed manufacturer whose licence specifies the applicable standard and the relevant voltage or reactive-power rating.

2
Verify the supplier's BIS CM/L number on the BIS online register before placing the purchase order. Confirm the licence scope covers the specific IS number, rated voltage, reactive-power class, and manufacturing facility for the consignment being imported.
Electrical Capacitors (Quality Control) Order, 2017 · S.O. 2434(E) dated 01-08-2017 · BIS (Conformity Assessment) Regulations, 2018
3
Ensure every 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 is non-compliant.

4
Quote the supplier's BIS CM/L number on the bill of entry, supported by the test certificate or conformity documentation for the applicable IS standard. Customs verifies the CM/L against the BIS register in real time; an absent, expired, or standard-scope-mismatched licence triggers consignment detention.

A word of counsel

The single most common error on this tariff line is presenting a CM/L licence that covers one IS standard while the consignment contains capacitors governed by a different one — for example, a licence against IS 2993 (AC motor capacitors) tendered for a shipment of IS 13340 self-healing power capacitors. Because three distinct Indian Standards map to this HSN, Customs verifies the licence scope down to the IS number and voltage rating; a standard mismatch constitutes a non-compliant import regardless of whether a BIS CM/L licence otherwise exists, and the consignment faces detention pending re-export or destruction.

Frequently asked

Does HSN 8532 29 90 require BIS certification?

Yes. Fixed electrical capacitors under this tariff line require an ISI Mark Scheme CM/L licence against IS 2993, IS 13340, or IS 13585 (Part 1) — depending on capacitor type — with effect from 1 August 2017 under the Electrical Capacitors (Quality Control) Order, 2017.

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

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 bill of entry must reflect the correct standard for the consignment.

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

No. A CM/L licence is standard-specific and voltage-rating-specific; a licence against IS 2993 does not authorise import of IS 13340 or IS 13585 (Part 1) products, and capacitors outside the licensed IS scope are treated as uncertified goods.

Is a separate customs overlay such as SIMS or EPR registration required for this HSN?

No separate customs overlay applies. The sole mandatory requirement is BIS ISI Mark Scheme compliance under the Electrical Capacitors (Quality Control) Order, 2017 referenced by S.O. 2434(E).
