This document is a list of “Prohibited and Controlled Substances in Packaging” attached tothe Green Procurement Guidelines. Please confirm that none of these substances arecontained in materials used for packaging (bags, steel drums, plastic drums, etc.). Othersubstances may also be prohibited or controlled for specific destinations.
If any of the following substances are contained in the packaging, please consult Nihon
Parkerizing in advance.

Note: This Guideline covers azo dyes and pigments that produce some aromatic amines. Thismeans azo compounds that create the amines listed in Appendix Table 1 by reductive
decomposition of the azo groups.
In addition, the threshold value of 30 ppm specified in the scope of coverage applies not to azo
dyes and pigments, but to amines listed in Appendix Table 1.
