NATRAX discusses Budget impact on auto industry
The National Automotive Test Tracks (NATRAX), one of the state-of-the-art testing and certification centres under NATRiP, and a flagship project of the Ministry of Heavy Industries, Govt of India, recently discussed the impact of India’s Union Budget 2021-22 in the country’s automotive industry. The webinar was attended by customers of NATRAX/auto industry professionals. The purpose was to make the auto industry professionals aware of the new avenues proposed in this budget for the growth of the auto industry.
The expectation from the Union Budget speech was very high, especially as Finance Minister Nirmala Sitharaman had promised to deliver a "first of its kind" and historic budget, the delegates observed.
NATRAX welcomed and appreciated the budget. There were seven presentations presented in the webinar wherein the speakers shared their knowledge on the budget pertaining to the auto industry and emphasised how NATRAX can support the requirements of testing and certification.
Dr N. Karuppaiah, Additional Director & Head, NATRAX delivered the welcome address and presented an overview of the budget focusing on six pillars- Health and Wellbeing, Physical & Financial Capital, and Infrastructure, Inclusive Development for Aspirational India, Reinvigorating Human Capital, and Minimum Government and Maximum Governance, of this budget. He also highlighted the subjects relevant to Auto Industry and outlined the plans of NATRAX orienting to the Budget as under.
Sagar Bendre, Asst. The manager (T&D) at NATRAX, presented his paper on Budget Allocation for Highway Infrastructure.The proposed investment, he said, will boost construction equipment sales and the heavy truck and tipper industry and eventually also result in better demand from the rural and wage-earning community in the country. "Highways are coming up at a rapid pace, and accordingly, the crash barriers are also being installed along the highways. To maintain quality and standard requirements, specification in the crash barrier testing will be an important contribution from NATRAX. NATRAX is now known for the crash barrier testing facility. This is a unique test facility which NATRAX has performed independently and indigenously," said Bendre.
This year’s budget has allocated INR 18,000 crore to support augmentation of bus transport services for public. Srihari SJ, Asst Manager (T&D), NATRAX, said this scheme will facilitate deployment of innovative PPP models to enable private sector players to finance, acquire, operate and maintain over 20,000 buses. “The scheme will boost automotive sector, provide fillip to economic growth, create employment opportunities for youth and enhance ease of mobility for urban residents,” said Srihari.
The emerging electric vehicles mobility paradigm is an important opportunity to foster Make–in-India for the advanced chemistry cells or EV batteries and their components, said Umesh Raghuwanshi, Asst. Manager (T&D) of NATRAX. Speaking on EV infrastructure, Raghuwanshi said, "GOI is providing modified special incentive package scheme and tax incentives that will help develop the indigenous testing and development ecosystem. Towards this NATRAX is working on the EV battery testing and development facility to work for the prospective EV makers to become self-reliant in the field of battery technology reducing the dependence on the import from China, Thailand and Japan."
"The budget outlay for the MSME sector has been doubled compared to last year. MSME dominates the auto component industry, and this will provide them with the necessary succour as the industry recovers," said Tulika Mazumdar, Sr. Engineer (P&TC) at NATRAX. He said start-ups in the automobile and allied industries can get immensely benefitted from NATRAX as the centre is equipped with state-of-the-art test tracks supplemented by the test laboratories for the components and system-level tests.
The government has also allocated INR 50,000 crore for National Research Foundation in this budget. JK Chakrabarty, Technical Advisor, said, "NATRAX, in association with prospective OEMs, will be working out projects in the areas of vehicle dynamics, Electric vehicle battery technology and vehicle testing. Suitable projects will be taken up in association with the National Research Foundation for funding. (TT)

Retreading Hangs In Balance Over Regulatory Conundrum
- By Gaurav Nandi
- December 30, 2025
A population of over 1.4 billion people catapulting into the world’s third largest automobile market with four million trucks plying across a road network of 6.3 million kilometres supported by a USD 13.4 billion tyre market and a mining sector contributing around 2–2.5 percent of the country’s GDP demonstrate the strength of India’s automobile, freight and tyre sectors.
The story doesn’t end there as the Central Government adopts a strategic approach on reducing carbon emissions across these verticals, especially automobile and tyres, with targets such as the Net Zero Carbon Emissions by 2070, battery electric vehicles target by 2030, zero-emission truck corridors, Extended Producer Responsibility for the tyre sector; the list just goes on.
Amidst all such statistics and targets, a silent spectator remains the old and varied sector of tyre retreading. In a recent news story reported by Tyre Trends, the Indian Tyre Technical Advisory Committee (ITTAC) had made a proposal to Tyre Retreading Education Association (TREA) for mandating certain standards that will improve the quality of retreads. ITTAC has made recommendations to the BIS committee. TREA is part of the same committee. ITTAC and TREA are recommending different standards.
These standards included BIS retread standards, namely IS 15725, IS 15753, IS 15524 and IS 9168. The ITTAC had partially aligned Indian requirements with ECE R109, the European regulatory benchmark.
In a reply to the proposal, which was accessed by Tyre Trends, TREA urged the Indian Tyre Technical Advisory Committee to seek a deferment or non-applicability of BIS standard IS 15704:2018 for retreaded commercial vehicle tyres, warning that mandatory enforcement could cripple the sector.
In the letter, TREA argued that IS 15704:2018 is largely modelled on new tyre manufacturing norms and is technically unsuitable for retreading, which is a restoration and recycling process.
The standard mandates advanced laboratory tests such as spectrometer-based rubber analysis, endurance testing and compound uniformity checks, requirements that most retreading units, particularly small and medium enterprises, are not equipped to meet
The association highlighted that even large retreaders lack the infrastructure and skilled manpower needed for BIS-grade testing, while the sheer number of retreading units would make inspections and certifications operationally unmanageable for regulators.
TREA warned that compliance costs linked to machinery upgrades, audits and quality control could force 70–80 percent of units to shut down, leading to job losses, higher fleet operating costs and adverse environmental outcomes due to reduced recycling
Instead, TREA proposed that BIS prioritise retreading-specific standards such as IS 13531 and IS 15524, which focus on materials, process control, safety and quality consistency.
The body has also called for a phased transition roadmap, MSME support and industry training before any stricter norms are enforced, stressing that abrupt implementation would undermine the sector’s role in India’s circular economy.
The conundrum
India has a total of 36 administrative divisions comprising 28 states and 8 union territories. The tyre retreading sector has been continuously supporting circularity goals since the early 1970s across the world’s largest economy without getting mainstream recognition.
Even after five decades in service, the industry battles different bottlenecks including fragmentation, manpower shortage, tax pressures brought about by the recent GST revisions and now the implementation of such standards, just to name a few.
The sole practice that can simultaneously reduce carbon emissions from tyres and extend tyre life is assumed the nemesis of an ‘infamous and dangerous practice’ in some states of the country.
However, the industry has been drawing its techniques and quality parameters from the world’s oldest retreading economy, Europe.
“Big retreaders in India already have the necessary processes in place that conform to IS 15524 standards. However, as the standard is not yet mandated, we have voiced support for it because it is process-oriented and outlines how retreading should be carried out, including buffing and building procedures,” said TREA Chairman Karun Sanghi.
He added, “This standard focuses on how the work is done rather than imposing product-level testing that cannot be practically implemented. The current debate on IS 15704 stems from it being fundamentally incompatible. The standard includes requirements such as sidewall marking and destructive testing of retreaded tyres, which are impractical in a retreading environment where each tyre differs in brand, size, application and usage history,” he added.
Destructive testing, he argued, assumes uniform batch sizes. In retreading, where every casing is unique, testing even a single tyre would mean destroying finished products without yielding representative results. Applying such a framework would effectively require the destruction of every tyre in a batch, making compliance unviable.
“We have submitted our response to ITTAC and are awaiting feedback from the committee. We remain open to continued dialogue and will engage further once the committee responds to our submission,” said Sanghi.
According to him, a typical retreader processes about 300 tyres a month across multiple brands including MRF, JK Tyre, Apollo and Michelin and applications ranging from buses and trucks to mining vehicles. These casings vary widely in load cycles, operating conditions and duty patterns, often across several models from the same manufacturer.
The committee has cited European standard ECE R109, but Sanghi points to structural differences: “Europe is a global retreading hub where tyre manufacturers such as Michelin and Bridgestone dominate operations, collect their own tyres, retread them and return them to fleets, making batch-based destructive testing relevant. A similar model exists in US, where large tyre companies lead retreading and largely self-regulate without a single overarching standard. The Indian scenario is different, especially with a fragmented market.”
He stressed that the industry is not opposed to standards but to those that cannot be practically applied, warning that adopting European manufacturing-oriented norms without accounting for India’s market structure and operating realities would be counter-productive.
The debate is no longer about whether standards are needed but whether they are fit for purpose. Without accounting for India’s fragmented retreading ecosystem, enforcing impractical norms could dismantle a circular industry in the name of compliance.

- December 29, 2025
Dunlop (company name: Sumitomo Rubber Industries, Ltd.) has made its way to the annual A-List of CDP for climate change and water security. This premier designation, awarded for the first time to the company in the 2025 evaluation, recognises world-leading performance in transparency, risk management and environmental action. CDP’s annual assessment is a key benchmark for corporate sustainability across climate, water and forests.
This achievement stems from the Group’s integrated approach to material issues outlined in its corporate philosophy. It treats the interconnected challenges of climate change, biodiversity and the circular economy holistically, advancing concrete initiatives under its long-term ‘Driving Our Future’ sustainability policy.
On climate, the Group’s science-based emission reduction targets for 2030 are validated by the Science Based Targets initiative. Operational efforts include pioneering green hydrogen production at its Shirakawa Factory and developing tyres made entirely from sustainable materials by 2050. The company also works to reduce emissions across its supply chain, lowers tyre rolling resistance to improve vehicle fuel economy and extends product life through retreading.
For water security, the strategy is driven by localised risk assessments at global production sites. In seven facilities identified as high-risk, the goal is to achieve 100 percent wastewater recycling by 2050. Progress is already evident, with the company’s Thailand factory reaching full wastewater recycling in 2024.
These coordinated actions on multiple environmental fronts formed the basis for the Group’s simultaneous top-tier recognition in both critical categories from CDP.
