As India moves to BS6 norms from BS4, many of us wonder: Is my car compliant, and why should I care?<\/p>\n\n\n\n<p>The good news is that it\u2019s not difficult to check if your car is compliant. This guide will help you assess if your automobile is compliant with BS6 vehicles starting year 2020 or not. Getting to know this not just keeps you on the right side of the law, but also helps you play a part in a cleaner environment.<\/p>\n\n\n\n<p>Go through this article to answer a big question for yourself: How to check Bharat Stage of vehicle?<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"what-is-the-bs4-launch-date-in-india\">What is the BS4 Launch Date in India?<\/h2>\n\n\n<p>Let&#8217;s first know about the official launch date for BS4 across India. BS4 launch date in India is April 1, 2017.<\/p>\n\n\n\n<p>If your vehicle was produced or registered in India after this date, then please be sure that it adhere to BS-IV standards. However, these norms were introduced in multiple states in 2010. Hence, you should keep reading further to learn to check your car&#8217;s compliance. <\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-check-bharat-stage-of-vehicle-bs4-or-bs6\">How to Check Bharat Stage of Vehicle: BS4 or BS6?<\/h2>\n\n\n<p>Knowing if your car is BS4 or BS6 will help you stay within legal limits and contribute to a cleaner India. So how do you figure out if your car is compliant?<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"locating-compliance-stickers-or-documentation\"><strong>Locating Compliance Stickers or Documentation<\/strong><\/h3>\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Windshield or Engine Bay Stickers:<\/strong> Look for stickers near the top corners of the windshield or inside the engine bay. These often mention the BS standard your car complies with.<\/li>\n\n\n\n<li><strong>Driver-Side Door Frame:<\/strong> Some manufacturers place compliance labels inside the driver-side door frame or on the chassis plate.<\/li>\n\n\n\n<li><strong>Fuel Cap or Engine Block:<\/strong> Check the fuel cap or engine block for manufacturer labels specifying the emission norms.<\/li>\n<\/ul>\n\n\n<h2 class=\"wp-block-heading\" id=\"key-aspects-of-bs6-vehicles\">Key Aspects of BS6 Vehicles<\/h2>\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Reduced Emissions:<\/strong> BS6 engines significantly decrease harmful pollutants-particularly nitrogen oxides (NOx)-in both diesel and petrol vehicles, resulting in cleaner urban air relative to BS4 standards.<\/li>\n\n\n\n<li><strong>Fuel Requirements:<\/strong> BS6 compliance necessitates the use of ultra\u2011low\u2011sulfur fuel; utilizing BS4\u2011grade petrol or diesel may contravene statutory emission regulations.<\/li>\n\n\n\n<li><strong>Adoption Timeline:<\/strong> Although the regulatory deadline was April&nbsp;2020, numerous manufacturers introduced BS6\u2011compliant models well in advance, often several months or years prior.<\/li>\n\n\n\n<li><strong>Impact on Vehicle Performance:<\/strong> BS6 technology frequently enhances fuel efficiency and lowers tailpipe emissions, although it may require adjustments to driving habits and adherence to more rigorous maintenance schedules.<\/li>\n\n\n\n<li><strong>Government Initiatives:<\/strong> The Government of India has actively endorsed BS6 technology as part of its strategy to mitigate air pollution and fulfil its commitments under the Paris Climate Agreement.<\/li>\n<\/ul>\n\n\n<h2 class=\"wp-block-heading\" id=\"what-is-bharat-stage-in-hsrp\">What is Bharat Stage in HSRP?<\/h2>\n\n\n<p>The <strong>Bharat Stage (BS) <\/strong>mentioned in the <strong>HSRP (High-Security Registration Plate)<\/strong> context refers to the emission standard that a vehicle complies with in India. These standards are set by the Government of India to regulate the output of air pollutants from vehicles.<\/p>\n\n\n\n<p>When applying for or updating an HSRP, you may be asked to <strong>select or enter the Bharat Stage (BS)<\/strong> of your vehicle. This is used for <strong>vehicle verification and record-keeping<\/strong>, and ensures that the HSRP is assigned correctly based on the vehicle&#8217;s emission standard.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"common-bharat-stage-categories\">Common Bharat Stage Categories<\/h3>\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>Bharat Stage<\/strong><\/td><td><strong>Common for Vehicles Manufactured in<\/strong><\/td><\/tr><tr><td>BS-I<\/td><td>Before 2005 (very rare now)<\/td><\/tr><tr><td>BS-II<\/td><td>2005\u20132010<\/td><\/tr><tr><td>BS-III<\/td><td>2010\u20132017<\/td><\/tr><tr><td>BS-IV<\/td><td>2017\u20132020<\/td><\/tr><tr><td>BS-VI<\/td><td>April 2020 onwards (BS-V was skipped)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n<h2 class=\"wp-block-heading\" id=\"impact-on-bs4-vehicles\">Impact on BS4 vehicles:<\/h2>\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Insurance Implications:<\/strong> Owners of BS4 vehicles may incur higher premiums or face restricted coverage options owing to the vehicle\u2019s age and heightened regulatory scrutiny.<\/li>\n\n\n\n<li><strong>Resale Challenges:<\/strong> The increasing prevalence of BS6\u2011compliant models may make it more difficult to sell a BS4 vehicle.<\/li>\n\n\n\n<li><strong>Operational Restrictions:<\/strong> Stricter emission norms could lead to bans or other limitations on BS4 vehicles in certain areas.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.spinny.com\/sell-used-car\/?utm_source=BSIVupgrade&amp;utm_medium=Blog\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1160\" height=\"653\" src=\"https:\/\/www.spinny.com\/blog\/wp-content\/uploads\/2025\/01\/BSIV-Upgrade-2-1160x653.webp\" alt=\"BSIV Upgrade\" class=\"wp-image-528614\" srcset=\"https:\/\/www.spinny.com\/blog\/wp-content\/uploads\/2025\/01\/BSIV-Upgrade-2-1160x653.webp 1160w, https:\/\/www.spinny.com\/blog\/wp-content\/uploads\/2025\/01\/BSIV-Upgrade-2-800x450.webp 800w, https:\/\/www.spinny.com\/blog\/wp-content\/uploads\/2025\/01\/BSIV-Upgrade-2-150x84.webp 150w, https:\/\/www.spinny.com\/blog\/wp-content\/uploads\/2025\/01\/BSIV-Upgrade-2.webp 1200w\" sizes=\"(max-width: 1160px) 100vw, 1160px\" \/><\/a><\/figure>\n\n\n<h3 class=\"wp-block-heading\" id=\"decoding-vehicle-documentation\"><strong>Decoding Vehicle Documentation<\/strong><\/h3>\n\n<h4 class=\"wp-block-heading\" id=\"registration-certificate\"><strong>Registration Certificate<\/strong><\/h4>\n\n\n<p>When a car is bought, a registration certificate comes with it. In the past it may have been a one-page document, but now it often is a small card at that small size. Most of the RC cards now carry the emission compliance at the name of the manufacturer\u2019s class or in the model section.<\/p>\n\n\n<h4 class=\"wp-block-heading\" id=\"rto-form-21\"><strong>RTO Form 21<\/strong><\/h4>\n\n\n<p>To register a car, the state&#8217;s RTO will require submitting the form 21 fully filled in. The form itself also indicates where the vehicle meets emission compliance; either besides its make and model name, before lines for &#8216;fitted with\/fitted without&#8217;.<\/p>\n\n\n<h4 class=\"wp-block-heading\" id=\"manufacturing-date\"><strong>Manufacturing Date<\/strong><\/h4>\n\n\n<p>Both above-mentioned documents can reveal the car&#8217;s production date.

VIN LOOKUP<\/strong><\/h3>\n\n\n<p>Your Vehicle Identification Number (VIN) is a unique 17 character code containing important info about your vehicle, such as its emissions standard. You can use the VIN to find out whether it complies if you don\u2019t have car documents.<\/p>\n\n\n\n<p>Find the vehicle identification number on the dashboard, in the engine bay, in the boot, or on the driver\u2019s door. The focus is on the ninth and tenth digits, which represent the month and year of manufacture. All cars before April 2020 had to follow BS4 norms and those launched afterwards follow BS6 prevalent rules.<\/p>\n\n\n\n<p>This is a simple solution that guarantees accurate checking of emission compliance without the need for paperwork.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"what-is-bs4-and-bs6-emission-standards\"><strong>What is BS4 and BS6 Emission Standards<\/strong>?<\/h2>\n\n\n<p>The Bharat Stage (BS) is an emission standard instituted by the Government of India, which limits the output of air pollutants from internal combustion engine equipment, including motor vehicles. These norms, introduced in 2000, are modeled after European emission standards and are periodically updated to limit vehicular pollution. BS4 (Bharat Stage 4) has been introduced in the country since 2010, while BS6 (Bharat Stage 6), an advancement over BS5, was introduced on 1 April 2020.<\/p>\n\n\n\n<p>BS6 not only makes the vehicle comply with norms, this transition also means stronger hold on Nitrogen oxides (NOx), particulate matter (PM), carbon monoxide (CO), and hydrocarbons (HC) emissions.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"differences-between-bs4-and-bs6\"><strong>Differences Between BS4 and BS6<\/strong><\/h3>\n\n<div class=\"wptb-container-legacy\" data-table-id=\"520872\">\n    <table class=\"wptb-preview-table wptb-element-main-table_setting-520872\" style=\"border-spacing: 3px 3px;

Which Bharat stage is my car?<\/h3><p class=\"saswp-faq-answer-text\">Ans: You can find your car&#8217;s Bharat Stage (BS) norm by checking your RC (Registration Certificate), PUC certificate, or by visiting the Vahan portal. It is usually based on your car\u2019s manufacturing or registration year &#8211; for example, most cars sold after April 2020 are BS6.<\/p><li style=\"list-style-type: none\"><h3 class=\"\">Q. How to find BS from RC?<\/h3><p class=\"saswp-faq-answer-text\">Ans: Check the \u201cFuel Norms\u201d, \u201cEmission Norms\u201d, or \u201cNorms Type\u201d section in your RC. It will mention something like BS-IV or BS-VI. If it&#8217;s not visible on the physical RC, you can also check the digital RC on the Parivahan Vahan Portal.<\/p><li style=\"list-style-type: none\"><h3 class=\"\">Q. Which year car is the BS4?<\/h3><p class=\"saswp-faq-answer-text\">Ans: BS4 (Bharat Stage IV) norms were applicable to vehicles manufactured and sold between April 2017 and March 2020. If your car was registered during this period, it is likely a BS4 vehicle.<\/p><li style=\"list-style-type: none\"><h3 class=\"\">Q. Is 2017 BS4 or BS6?<\/h3><p class=\"saswp-faq-answer-text\">Ans: A car registered in 2017 is most likely BS4, as BS6 only became mandatory from April 1, 2020. However, a few premium BS6-compliant models were introduced early in late 2019\u20132020.<\/p><li style=\"list-style-type: none\"><h3 class=\"\">Q. How to know BS3 or BS4?<\/h3><p class=\"saswp-faq-answer-text\">Ans: To distinguish between BS3 and BS4 you can check the RC book or Vahan portal for the &#8220;Norms Type&#8221;. You can also note that the cars registered between 2010 and 2017 are usually BS3 or BS4. Also, BS4 cars have stricter emission controls and may feature OBD (On-Board Diagnostics) systems.<\/p><li style=\"list-style-type: none\"><h3 class=\"\">Q. Which Bharat stage is now?<\/h3><p class=\"saswp-faq-answer-text\">Ans: As of 2025, the current standard for new vehicles in India is BS6 (Bharat Stage VI). All vehicles sold after April 1, 2020 must comply with BS6 norms, which are significantly stricter than previous stages.<\/p><\/ul><\/div>","protected":false},"excerpt":{"rendered":"<p>Confused between BS4 and BS6?
