2 / 3 and employees act with high ethical standards and sound common sense in their daily activities to implement sound initiatives across the supply chain. This includes compliance with international norms and the laws of individual countries and/or regions, respect for human rights, safety for workers, and environmental conservation."

Casio Procurement Policy (https://world.casio.com/csr/social/materiality/procure/) states the following:

"2. Compliance with laws and social norms

Casio's procurement activities comply with all relevant laws, social norms, standards and treaties worldwide, including the protection of human rights, the prohibition of child labor, forced labor and discrimination, and avoiding the use of conflict minerals, and respect for freedom of association, the right to associate, and the right to collective bargaining, as well as ensure that absolutely no contact is made with organized criminal elements. Therefore, Casio requires its suppliers to observe the same legal and social requirements."

The company's statement and procurement policy does not seem to put the responsibility on suppliers beyond tier 1.
