Fixed mica dielectric capacitors for AC power systems

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 2993

HSN 8532 29 10 (fixed capacitors of mica dielectric) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 2993, IS 13340, and 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
Verify the foreign manufacturer holds a current Bureau of Indian Standards CM/L licence against the applicable Indian Standard — IS 2993 for AC motor capacitors, IS 13340 for self-healing power capacitors up to 650 V, or IS 13585 (Part 1) for non-self-healing shunt power capacitors up to 1000 V. Confirm the licensed scope covers the specific capacitor type and facility before placing the purchase order.

2
Ensure every capacitor in the consignment bears the ISI mark and the supplier's CM/L number. Marking must appear on the product itself; packaging-level marking alone does not satisfy the BIS (Conformity Assessment) Regulations, 2018 Scheme-I requirements.

3
Obtain and retain the supplier's test reports confirming conformity to the relevant Indian Standard. IS 2993 governs AC motor capacitors; IS 13340 applies to self-healing type power capacitors; IS 13585 (Part 1) covers non-self-healing shunt power capacitors, including testing, rating, and safety requirements.

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

A word of counsel

The single most common error on this tariff line is assuming a single CM/L licence covering one capacitor type extends to all three product families at HSN 8532 29 10. IS 2993 (AC motor capacitors), IS 13340 (self-healing power capacitors to 650 V), and IS 13585 (Part 1) (non-self-healing shunt capacitors to 1000 V) are distinct standards with distinct licensed scopes; a consignment mixing capacitor types sourced from a manufacturer licensed only under IS 2993 will face detention on the IS 13340 and IS 13585 items regardless of the IS 2993 compliance.

Frequently asked

Does HSN 8532 29 10 require BIS certification?

Yes. Fixed mica dielectric capacitors under this tariff line require conformity to IS 2993, IS 13340, or IS 13585 (Part 1) under the ISI Mark Scheme, mandatory with effect from 01 August 2017 under the Electrical Capacitors (Quality Control) Order, 2017 notified via S.O. 2434(E).

Which Indian Standard applies to my specific capacitor type?

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 and including 1000 V.

Does a CM/L licence for one Indian Standard automatically cover capacitors governed by the other two standards?

No. Each CM/L licence is standard-specific and product-scope-specific; a licence granted against IS 2993 does not authorise import of capacitors that fall within IS 13340 or IS 13585 (Part 1).

Is the CM/L licence facility-specific?

Yes. A BIS CM/L licence is tied to the specific manufacturing facility declared in the application; capacitors produced at an unlicensed plant, even by the same corporate entity, are not covered and cannot lawfully bear the ISI mark.
