India Tightens PMP Rules for E-Truck Components Under PM E-DRIVE Scheme

India has introduced stricter localization mandates for electric truck components by revising the Phased Manufacturing Programme under the PM E-DRIVE scheme. The update specifically targets N2 and N3 category e-trucks and focuses on key electronic systems such as Battery Management Systems, DC-DC converters, and Vehicle Control Units. The move signals a clear policy push toward strengthening domestic manufacturing capabilities and reducing dependence on imports in the rapidly expanding electric commercial vehicle segment. The revised framework lays out phased timelines with increasing levels of localization requirements for manufacturers operating in the country.

Stricter BMS Localization Requirements from 2026

Under the revised PMP framework, Battery Management Systems will face the most stringent localization norms. From September 1, 2026, domestic manufacturing must include full assembly of electronic components, semiconductors, and connectors directly on the PCB. Additionally, manufacturers must perform wiring, connector fitment, heatsink integration, enclosure assembly, and complete software or firmware flashing within India. Until August 31, 2026, imports of BMS units will still be permitted, providing a transition window for suppliers to align with the new requirements and build localized production capabilities.

Two-Stage Localization Plan for DC-DC Converters and VCUs

The amendment introduces a phased localization roadmap for DC-DC converters and Vehicle Control Units. The first stage, effective from September 1, 2025, mandates domestic integration of assembled PCBs along with associated components. This requirement is already in force and establishes the foundation for localized assembly. The second stage, beginning September 1, 2026, raises the bar significantly by requiring complete assembly of electronic components, semiconductors, and connectors on the PCB within India, along with associated mechanical and software integration processes.

Component Localization Timeline Overview

The updated PMP framework defines clear timelines for transitioning from partial to full localization of key electronic systems in e-trucks.

Policy Push to Strengthen Domestic EV Supply Chain

The revised PMP guidelines are designed to accelerate localization across the electric vehicle ecosystem, particularly in high-value electronic components. By mandating in-country assembly of semiconductors, connectors, and software integration, the policy aims to foster local supplier ecosystems and encourage investment in advanced manufacturing. This shift is expected to enhance supply chain resilience while also aligning with broader national objectives of reducing import dependency and boosting domestic industrial capabilities in the EV sector.

Frequently Asked Questions

What changes have been introduced in India’s PMP for e-trucks?
The revised PMP introduces stricter localization requirements for critical electronic components used in N2 and N3 electric trucks under the PM E-DRIVE scheme. From September 2026, manufacturers must perform complete PCB-level assembly, including semiconductors and software integration within India. Imports of Battery Management Systems will be restricted after August 2026, while DC-DC converters and VCUs must follow a two-stage localization roadmap. These changes aim to boost domestic manufacturing and strengthen the EV supply chain.

When will the new localization rules for BMS and other components take effect?
The localization rules will be implemented in phases, with key deadlines already defined under the PMP amendment. For DC-DC converters and VCUs, the first stage began on September 1, 2025, requiring PCBA integration. The second stage starts on September 1, 2026, mandating full PCB-level assembly. For Battery Management Systems, imports are allowed only until August 31, 2026, after which complete domestic manufacturing becomes compulsory, including hardware assembly and software integration.
