Ceramic dielectric, single layer

Single-layer ceramic dielectric fixed capacitors (AC motor, power capacitors)

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 2993

HSN 8532 23 00 (single-layer ceramic dielectric fixed capacitors) 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 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 the precise capacitor type before sourcing: AC motor capacitors require CM/L against IS 2993; self-healing power capacitors for AC systems up to 650 V require CM/L against IS 13340; non-self-healing shunt power capacitors for AC systems up to 1000 V require CM/L against IS 13585 (Part 1). Verify the supplier's CM/L on the BIS online register, confirming the licensed standard matches the product type.

2
Confirm the supplier's CM/L covers the specific rated voltage range, capacitance value, and manufacturing facility of the consignment. Capacitors outside the licensed voltage or product scope are not covered, even if the manufacturer holds a valid CM/L against the correct IS number.

3
Ensure every capacitor in the consignment bears the ISI mark and the supplier's CM/L number. Marking must appear on the product itself; marking only on packaging or carton labels does not satisfy the BIS Act, 2016 marking requirement.

4
Quote the supplier's BIS CM/L number and the applicable IS standard (IS 2993, IS 13340, or IS 13585 Part 1) 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.

A word of counsel

The single most common error on this tariff line is treating the three applicable IS standards as interchangeable and quoting a CM/L against IS 2993 (AC motor capacitors) on a bill of entry covering self-healing power capacitors that legally require IS 13340 — or vice versa. Each standard maps to a distinct product type and rated-voltage envelope; a CM/L held against the wrong standard renders the consignment non-compliant regardless of the manufacturer's overall BIS standing, and customs will detain the shipment pending fresh certification evidence.

Frequently asked

Does HSN 8532 23 00 require BIS certification?

Yes. Single-layer ceramic dielectric fixed capacitors are subject to the ISI Mark Scheme under the Electrical Capacitors (Quality Control) Order, 2017 with effect from 01 August 2017; 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 to the product type.

Which Indian Standard applies to my capacitor shipment?

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 correct standard is determined by the product's technical specification, not the importer's preference.

Does a single CM/L licence cover all capacitor variants a manufacturer produces?

No. A CM/L is standard-specific and scope-specific; it covers only the product type, rated voltage range, and manufacturing facility stated in the licence. Variants outside the licensed scope require a separate CM/L, and customs detains consignments on any scope mismatch.

Is there any customs-clearance overlay registration required in addition to BIS compliance?

No separate overlay such as SIMS or EPR registration applies to HSN 8532 23 00. BIS CM/L compliance under the Electrical Capacitors (Quality Control) Order, 2017 is the primary and sole mandatory pre-import requirement for this tariff line.
