Quality Assurance Measures

Essentials for Ensuring Quality

Making Our Products

Raw Materials

We source our raw materials from trusted suppliers and use only those materials whose safety we can be sure of in accordance with Nissui standards.

Checks Using Raw Material Product Certificates

Using a format we developed ourselves, we check information about the raw materials in detail. This information is centrally managed in-house.

Checks of Raw Material Manufacturers

When we use a new raw material, we collect information about the production site beforehand to make sure that it is problem-free.
