CPCB CLEARANCE

HSN 8459 31 00 (Numerically controlled knee-type milling machines) is subject to Central Pollution Control Board (CPCB) Extended Producer Responsibility (EPR) authorisation under the E-Waste (Management) Rules, 2022, notified vide G.S.R. 801(E) dated 02-11-2022. The EPR obligation applies to importers of equipment for milling or similar processing of metal and other materials, with the exception of large-scale stationary industrial tools, and is waived only for micro-enterprises as defined under the MSME Development Act, 2006.

Compliance steps

1
Obtain EPR authorisation from the Central Pollution Control Board before importing numerically controlled knee-type milling machines. The machine category covered is equipment for milling or similar processing of wood, metal, and other materials, excluding large-scale stationary industrial tools, per Schedule I of the E-Waste (Management) Rules, 2022.

2
If the importing entity qualifies as a micro-enterprise under the MSME Development Act, 2006, retain the Udyam registration certificate confirming micro-enterprise status, as EPR authorisation does not apply to such entities and customs may seek documentary evidence of the exemption.

A word of counsel

The most common error on this tariff line is assuming that all numerically controlled machining centres are 'large-scale stationary industrial tools' and therefore outside EPR scope. The Schedule I exclusion is narrowly construed; unless the machine is explicitly classified as a large-scale stationary industrial tool, CPCB EPR authorisation is required, and importing without it exposes the consignment to detention and CPCB enforcement action independent of customs clearance.

Frequently asked

Does HSN 8459 31 00 require BIS certification?

No, no BIS Quality Control Order covers numerically controlled knee-type milling machines under this tariff line. The operative compliance obligation is Central Pollution Control Board Extended Producer Responsibility authorisation under the E-Waste (Management) Rules, 2022, notified vide G.S.R. 801(E) dated 02-11-2022.

Does the EPR authorisation requirement apply to every importer of HSN 8459 31 00?

No. Micro-enterprises as defined under the MSME Development Act, 2006 are exempt from EPR authorisation; all other importers, including small, medium, and large enterprises, must hold current CPCB EPR authorisation before filing the bill of entry.

Does the large-scale stationary industrial tool exclusion cover most numerically controlled milling machines?

Not automatically. The exclusion is product-specific and narrowly applied under Schedule I of the E-Waste (Management) Rules, 2022; importers should obtain a written classification determination from CPCB before relying on the exclusion, as an incorrect claim results in consignment detention and EPR non-compliance liability.
