Supplier Selection Standards

The Yamaha Group opens its doors to suppliers from around the world, applying the following standards comprehensively in the selection and evaluation of suppliers as business partners.


Suppliers should have a quality assurance system in place and be able to guarantee suitable levels of quality and safety. Moreover, suppliers should be able to provide a comprehensive level of service after purchase to address any problems such as product liability.

Delivery timing

Suppliers should be able to meet scheduled delivery times, address manufacturing changes flexibly, and reduce lead times.


Suppliers should consistently provide market-competitive pricing.


Suppliers should be able to build relationships with Yamaha that ensure the precise and prompt provision of information and responses between both parties.


Suppliers should possess sound management status, and have social credibility.


Suppliers should be able to offer improvement proposals through VA/VE activities, including development of new materials and new technology.

Legal compliance

Suppliers should be in compliance with the laws and provisions, ordinances, and social norms of each relevant country and region.

CSR initiatives

Suppliers should work toward management that gives sufficient consideration to human rights, health and safety, the environment, fair trade, quality, safety, information security, and social contribution.

Combating conflict minerals

Mineral resources such as tin, tantalum, tungsten, gold and others mined in the Republic of the Congo and neighboring countries are called “conflict minerals” as they may be the source of funds for armed groups violating human rights through inhumane acts including violence and plunder. Aiming to procure minerals that play no part in the violation of human rights or environmental destruction, Yamaha promotes efforts to stop the use of conflict minerals. To satisfy our business partners procuring Yamaha products who demand that we investigate the origin of raw materials, from fiscal 2013, Yamaha started examining the status of conflict mineral utilization, mostly focusing on products comprised of electronic components. If, as a result of this examination, conflict minerals that are associated with environmental destruction or in violation of human rights are discovered to be included in certain products, we will implement measures to eliminate them. We ask that suppliers understand the aims of our initiatives with regard to these types of minerals and cooperate with our examinations regarding their use.
