INMETRO Certification for Automotive Components

INMETRO (The National Institute of Metrology, Quality and Technology) is the official Brazilian government body responsible for regulating product conformity, safety, and quality. Automotive components, whether manufactured in Brazil or imported, must meet INMETRO requirements before entering the Brazilian market.

TÜV Rheinland, as a globally recognized Certification Body (CB), offers end-to-end support for INMETRO certification, ensuring your automotive products comply with Brazilian standards and reach the market efficiently and confidently.

INMETRO certification is mandatory for a wide range of automotive parts and is based on comprehensive testing, inspection, and factory audits. The products must bear both the INMETRO mark and the mark of the recognized CB, confirming their compliance.

• Mandatory for Market Access: Certification is legally required for both locally produced and imported auto parts sold in Brazil.
• Product Safety and Quality: Ensures that your components meet the minimum safety and performance standards.
• Brand Trust and Compliance: Demonstrates commitment to international best practices and Brazilian regulatory requirements.
• Avoid Fines and Rejection: Non-compliance can lead to customs clearance issues, product recalls, and legal penalties.

INMETRO regulations are designed to:

• Ensure consumer safety
• Promote fair market competition
• Reduce technical barriers to trade
• Guarantee product reliability and quality

INMETRO regulations cover a broad and evolving list of automotive components, including:

• Wheels and Tires: Automotive Wheels, New Tires
• Lighting and Glass: Lamps, Laminated Safety Glass, Tempered Safety Glass
• Mechanical Components: Brake Linings, Axel Shafts, Rod Bearings, Retaining Rings, Link Rods
