This one was difficult.

"The Supplier Code makes reference to the Nidec Group Corporate Social Responsibility Charter ( https://www.nidec.com/en/sustainability/principle/charter/) and more specifically to: ethical behaviour, anti-corruption, conflicts of interest, conditions of employment, discrimination, freedom to associate, humane treatment, child labour, working and living conditions, the environment, management systems and supply chain management"

1. From this, I chose the answers Supplier Code of Conduct has clauses on slavery. 
2. Although child labour is mentioned, it is not written that it is prohibited, so I did not choose it. When one opens the link, there is a clause "We strive to achieve a work environment based on mutual respect for individuality and human rights and free from abusive labor practices, such as forced and child labor", but I answered this based on what could be found in the statement.
3. I ended up choosing the "labour rights" as freedom to associate, conditions of employment, and working and living conditions are mentioned

I chose tier 1 suppliers only. There is a sentence in the statement "Suppliers have a responsibility to adhere to the Supplier Code and to promote human rights within their own supply chains", but I would not interpret responsibility to promote human rights within one's own supply chain as binding.

p.1,2

"The Supplier Code clearly communicates Nidec’s expectations with regard to suppliers. !n the 2021 Financial Year, the Nide c Group's Basic Policy on Human Rights ( https://www.nidec.com/en/sustainability/social/hum anrights/ )was established. We expect that not only our officers and employees but also our bu siness partners and suppliers will support and comply with this policy, and we will promote coll aborative efforts to respect human rights. The Supplier Code makes reference to the Nidec Gro up Corporate Social Responsibility Charter ( https://www.nidec.com/en/sustainability/princip! e/charter/ ) and more specifically to: ethical behaviour, anti-corruption, conflicts of interest, co nditions of employment, discrimination, freedom to associate, humane treatment, child fabou r, working and living conditions, the environment, management systems and supply chain man agement. Suppliers have a responsibility to adhere to the Supplier Code and to promote huma nrights within their own supply chains. The breadth of Nidec’s supply chain has posed a challe

nge to Nidec within the 2022 Financial Year with respect to ensuring compliance by all supplier 5 with the Code. Nidec continues to encourage suppliers to comply with the Supplier Code. Nidec makes it a part of its fundamental policy to comply with all the rules and regulations promulgated under the Responsible Business Alliance Code of Conduct (the “RBA Code of Conduct”), which covers both slavery and human trafficking, and expects its suppliers to do the same."
