 Concrete technological capabilities demanded by the world.

New High-Quality, High-Efficiency "Total Assembly" Production System.

TOA's "total assembly" production system helps us more efficiently produce our wide range of products while maintaining the highest quality. In this system, several workers form a work station, and each station completes the entire assembly of their assigned product, taking responsibility for all production processes, from parts purchasing to the supply of the finished product. This has resulted in a significant increase in product precision, greatly minimized waste and heightened production efficiency, while increasing the speed with which our products can be shipped to market. 

Quality And Vision Recognized Around The World. 

TOA has received certification under ISO9001 international standards for quality assurance, in recognition of TOA's establishment of a total quality control system for manufacturing activities ranging from product planning to development, production, installation and after-sales service. Moreover, TOA has been focusing on protecting the Earth's environment as one of its key management themes, and actively promotes the development of technologies and products that reduce our impact on the earth. As a result of these efforts, TOA has also received ISO14001 certification, the international standards for environmental management systems. Further, TOA has achieved Level 2 of the CMMI (Capability Maturity Model Integration) international index for businesses involved with railway vehicles, which evaluates software development processes to ascertain the degree of capability attained. Continuous efforts are being made to improve our development capabilities and quality.

Prudent System For Quality Maintenance.

To ensure the confident, long-term use of its products, TOA has established a well-organized customer support system, including an Information Center. These facilities are always prepared to quickly respond to all technical questions and provide consultations on acoustics and sound, as well as to answer inquiries about our products. All comments and suggestions received are studied and passed on to corresponding departments as a means of ensuring better products in the future.

Proposition 65 

What is Proposition 65?

The State of California enacted California’s Safe Drinking Water and Toxic Enforcement Act of 1986, better known as Proposition 65 (Prop 65) for addressing California consumers’ concerns over possible exposure to toxic chemicals. Prop 65 requires the State of California to maintain a list of chemicals believed by the State to cause cancer or reproductive harm at certain levels of exposure. That list has grown to around 900 substances. If a product contains any of these chemicals, a warning label may be required. 

Note that Prop 65 is a “right to know” law that advises if certain chemicals are present; it does not ban or prohibit use of any of the 900 listed chemicals. Many of the chemicals on the list (such as Vitamin A, testosterone and estrogen) are necessary to human life but can have deleterious effects at certain exposure levels. 

Prop 65 requires businesses with 10 or more employees to provide a “clear and reasonable warning” before exposing individuals in California to the regulated chemicals.  

How TOA Electronics, Inc. Reacts?

To meet this requirement, TOA Electronics, Inc., a subsidiary company of TOA Corporation headquartered in Japan carries an approved short-form Prop 65 warning on our products, regardless of where they might be sold. We do this out of an abundance of caution and to ensure compliance with the complex Prop 65 notice requirements.

We are committed to providing safe products and believe we do so. Our products are designed to meet or exceed all applicable laws regulating product safety and content. This includes our internal Environmental Quality Standard which is designed to satisfy the European Union’s Restriction of Hazardous Substances (RoHS) Directive, which applies specifically to the electronics industry.
