India Expands Legal Metrology Rules to Include Hydrogen and Clean Fuel Dispensers
India’s Department of Consumer Affairs has expanded the scope of Government Approved Test Centres (GATCs) under the Legal Metrology Rules, enabling the verification and re-verification of hydrogen, LNG and CNG fuel dispensers as the country accelerates the rollout of cleaner transport fuels.
The reforms, announced by the Ministry of Consumer Affairs, Food and Public Distribution on 24 May 2026, are designed to strengthen India’s legal metrology system, improve nationwide verification capacity and support the development of clean fuel infrastructure.
Under the amended framework, five additional categories of fuel dispensing systems have been brought within the GATC system: petrol and diesel dispensers, CNG dispensers, LPG dispensers, LNG dispensers and hydrogen dispensers. The inclusion of hydrogen technology marks a significant step in preparing India’s regulatory infrastructure for emerging low-carbon transport systems.
The government said the move is intended to ensure accurate fuel measurement, improve transparency in commercial transactions and increase consumer confidence as adoption of alternative fuels grows across the country. Government Approved Test Centres, which include qualified private laboratories and industrial facilities, are authorised to verify and re-verify specified weights and measuring instruments under India’s legal metrology framework.
Officials said expanding the role of GATCs would improve service delivery and reduce delays by increasing the availability of technical verification services. With the latest amendments, GATCs are now authorised to verify 23 categories of weights and measures.
The revised rules also give state governments greater flexibility to notify additional categories of instruments for verification under their own legal metrology regulations. At the same time, officers of Joint Secretary rank and above have been granted expanded authority to process approvals and related matters more quickly.
New verification fees have also been introduced under the amended rules. Petrol and diesel dispensers will attract a fee of ₹5,000 per nozzle, while CNG, LPG, LNG and hydrogen dispensers will be charged ₹10,000 per nozzle for verification services.
The Department of Consumer Affairs said the reforms support broader government objectives around technology-driven governance, transparency in trade practices and the “Atmanirbhar Bharat” initiative. The ministry added that the updated framework aligns India’s metrology system more closely with international standards and recommendations set by the International Organization of Legal Metrology.
The expansion of the GATC system comes as India continues investing in cleaner mobility and alternative fuel infrastructure, with hydrogen increasingly viewed as a long-term component of the country’s industrial and transport decarbonisation strategy.
