Compliance steps

1
Obtain and upload a valid CPCB type-approval certificate and certificate of conformity of production covering emission and noise norms for the specific fuel type (diesel, petrol, kerosene, LPG, or natural gas). Conformance labelling must be affixed to the unit in accordance with Schedule I of the Environment (Protection) Rules, 1986, Serial Nos. 88, 94, 95, 95A, 95B and 95C.

2
If the consignment comprises second-hand diesel generating sets, note that import is Restricted under Para 2.31 of the Foreign Trade Policy. Confirm compliance with General Note 2 to the Import Policy before filing the bill of entry; non-compliance results in consignment detention.

3
Verify that the bill of entry and supporting documents align with CBIC guidance issued jointly with CPCB. Customs officers are directed to check type-approval and conformance-labelling compliance at the out-of-charge stage per the CBIC letter.

A word of counsel

The most common error on this tariff line is presenting a type-approval certificate covering one fuel variant while importing a unit configured for a different fuel — CPCB type approvals are fuel-specific, and a petrol-configured set cannot be cleared on a diesel-variant certificate. Verify that the certificate of conformity of production matches the exact fuel type and power output of every unit in the consignment; a mismatch triggers consignment detention at customs and a referral back to CPCB for fresh type-approval, which can result in extended demurrage and ground rent at the port.

Frequently asked

Does HSN 8502 20 90 require BIS certification?

No, no BIS Quality Control Order covers spark-ignition generating sets under this tariff line. Import is governed by the Central Pollution Control Board under Schedule I of the Environment (Protection) Rules, 1986, with emission/noise type-approval and conformance-labelling requirements as the operative compliance framework.

Are second-hand spark-ignition generating sets freely importable under HSN 8502 20 90?

No. Import of second-hand diesel generating sets is Restricted under Para 2.31 of the Foreign Trade Policy, and compliance with General Note 2 to the Import Policy is required; importers must resolve the Restricted-import status before the bill of entry is filed.

What happens if the conformance label is missing from the unit at the port of import?

Absence of the CPCB-mandated conformance label is treated as non-compliance with Schedule I of the Environment (Protection) Rules, 1986, and the customs proper officer is directed under the CBIC letter dated 26-05-2023 to withhold out-of-charge clearance until the deficiency is rectified or the consignment is re-exported.
