Compliance steps

1
Verify the foreign supplier's BIS Compulsory Registration Scheme R-number on the BIS portal against IS 60669 (Part 2, Section 1:2008) for LED dimmers or IS 15787:2008 for switch-socket-outlets. The R-number must be model-specific, current, and issued under Scheme-II or Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018 as applicable.

2
Confirm the applicable enforcement date for the product sub-category: IS 15787:2008 applies from 01-07-2024 for regular enterprises, from 01-10-2024 for small enterprises, and from 01-01-2025 for micro enterprises. Source only from a BIS-registered manufacturer whose R-number is valid as of the consignment's bill of entry date.

3
Ensure each unit bears the Standard Mark and the supplier's BIS R-number per the applicable scheme. For IS 60669 dimmers, marking must comply with Scheme-II of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018; for IS 15787:2008 switch-socket-outlets, marking must comply with Scheme-I.

4
Check whether the product falls within the Mandatory Testing and Certification of Telecom Equipment (MTCTE) list notified under the Indian Telegraph (Amendment) Rules, 2017. If listed, obtain MTCTE certification from the Telecommunications Engineering Centre in addition to BIS registration before filing the bill of entry.

5
Quote the BIS R-number on the bill of entry and ensure compliance with DGFT Notification 13/2024-25 and CBIC Instruction 27/2025-Cus. Customs verifies the R-number in real time against the BIS register; an absent, expired, or model-scope-mismatched registration triggers consignment detention.

A word of counsel

The single most common error on this tariff line is applying a single BIS R-number to a mixed consignment containing both LED dimmers and switch-socket-outlets without verifying that each model code carries its own separate registration. IS 60669 (Scheme-II, CRS) and IS 15787:2008 (Scheme-I, ISI Mark) are governed by two distinct Quality Control Orders with different scheme mechanics; a supplier's R-number under one standard does not extend to product variants falling under the other. Customs detention for model-code mismatch is the routine consequence of conflating the two registrations at the bill-of-entry stage.

Frequently asked

Does HSN 8536 90 90 require BIS certification?

Yes. LED dimmers require Bureau of Indian Standards registration under the Compulsory Registration Scheme against IS 60669 (Part 2, Section 1:2008) from 04 July 2019; switch-socket-outlets require registration against IS 15787:2008 under the ISI Mark Scheme from 01 July 2024 onward, with staggered dates for small and micro enterprises.

Do LED dimmers and switch-socket-outlets require separate BIS registrations?

Yes. IS 60669 and IS 15787:2008 are distinct standards governed by separate Quality Control Orders; each model requires its own model-specific R-number or CM/L licence issued under the applicable scheme.

What is the staggered enforcement timeline for IS 15787:2008 switch-socket-outlets?

Per S.O. 43(E), the IS 15787:2008 obligation applies from 01-07-2024 for regular enterprises, 01-10-2024 for small enterprises, and 01-01-2025 for micro enterprises as defined under the relevant MSME classification.

Does a single BIS R-number cover all variants of a product model from one manufacturer?

No. The R-number is model-specific and facility-specific; product variants outside the registered model code or manufactured at an unlicensed facility are not covered and will be detained at customs on a scope mismatch.
