Best and most trusted BIS Consultant in Thailand – Sun Certifications India

Thailand and India share more than just geography — they share one of the most dynamic and fast-growing trade relationships in Asia. As a leading manufacturing hub for electronics, automotive components, rubber products, food processing machinery, and petrochemicals, Thailand is home to thousands of manufacturers who are actively looking to expand into new markets. India, with its 1.4 billion consumers and rapidly growing industrial base, is an increasingly attractive destination.

But selling products in India is not as simple as finding a local distributor. India has a mandatory product certification framework governed by the Bureau of Indian Standards (BIS) — and for most regulated product categories, BIS certification is a legal requirement before your product can be imported, sold, or distributed anywhere in India.

At Sun Certifications India, we have been helping foreign manufacturers navigate India's BIS certification requirements since 2016. We understand the documentation expectations, the overseas factory audit process, and the specific challenges that Thai manufacturers face when entering the Indian regulatory system for the first time.

If you are a manufacturer based in Thailand looking to access the Indian market, this page gives you everything you need — and shows you exactly how we make the process manageable.

Why Thailand-based manufacturers are prioritising India:

• The ASEAN-India Free Trade Agreement (AIFTA) is already in force — Thai goods benefit from reduced or zero import duties on thousands of product lines, making India cost-competitive for Thai exporters
• India's infrastructure boom is driving massive demand for construction materials, electrical equipment, and industrial machinery — areas where Thai manufacturers are globally competitive
• Thailand's position as a major hub for Japanese and Korean OEM manufacturing means many Thai factories already produce to international quality standards — making BIS compliance more achievable than manufacturers expect
• India's automotive sector — one of the largest in the world — is a major buyer of Thai-manufactured components, rubber parts, and precision assemblies
• The Indian government's PLI (Production Linked Incentive) schemes are drawing global supply chain investment, creating new procurement opportunities for foreign suppliers

BIS Certification Overview — What Thailand companies need to know

BIS (Bureau of Indian Standards) is India's national standards body, established under the BIS Act, 2016, and operating under the Ministry of Consumer Affairs. Every product regulated under a Quality Control Order (QCO) must carry a valid BIS certification before it can be legally sold or imported into India.

Key facts every Thai manufacturer must understand:

• BIS certification is product-specific and scheme-specific — there is no single blanket approval for your company
• The mandatory product list is continuously expanding — categories that were unregulated two years ago may be mandatory today
• Foreign manufacturers cannot apply to BIS directly — you must appoint an Authorized Indian Representative (AIR) who acts as your official liaison with BIS in India
• For ISI Mark products, BIS conducts overseas factory audits — a BIS officer travels to your Thai manufacturing facility to verify compliance
• Products imported into India without valid BIS certification in regulated categories can be detained at customs, resulting in costly delays, penalties, or destruction of goods
