INTERNATIONAL COMPANY CERTIFICATION→
ISO 9001:2000 Certification - International Service Organization (ISO) is a worldwide organization that sets technical standards for testing and quality purposes for various international industries. ISO 9001:2000 is the latest quality management system for businesses. It basically creates a unique structure, development and implementation of a QMS in order to increase the quality of business transactions, quality and customer satisfaction.

JAPANESE→
JWL- Japanese wheels must have a "JWL" logo on the wheel and "JWL" (Japan Light Wheel Alloy) is a compilation of standards defined by the Japanese Government to ensure the vehicle's safety for aluminum road wheels. Every wheel put to market must be tested to meet JWL standards before a wheel can be put out to market in Japan. These standards are generally accepted worldwide as acceptable for most road conditions. That is why you will see these marks on European and other Asian country wheels.

VIA Certification - Vehicle Inspection Association (VIA) is a third-party group in Japan which can test and verify whether or not any alloy wheels can meet JWL certification standards.

JAWA Certificate Sticker
The JAWA Quality Certificates: Since 1995, JAWA has introduced the “JAWA Quality Certificate” system to protect and develop consumer confidence in wheel safety and quality. The certificate guarantees that all products qualify to the JWL and JWL-T light alloy disc wheel standards approved by Japanese government.

VIA Mark
A third-party entity called the Vehicle Inspection Association verifies whether a product meets the requirements prescribed by the JWL or JWL-T standard. This association permits a product to bear a VIA mark if it passes rigorous quality and strength verification tests conducted in accordance with the JWL or JWL-T standard.

GERMAN→
TUV Certification - Technischer Uberwachungs-Verien (TUV) (Technical Examination Association) in Germany. This is another third-party testing group which began in Germany and now has locations worldwide. The TUV Certification is the highest performance and durability standard any product can hope to meet. To even be considered for testing, all companies must first be ISO 9001:2000.
