We devised standard guidelines on green procurement to reduce the environmental impact of our products. To work for environmental conservation with our customer in mind, we wish to create and sustain a culture of recycling both in terms of supply and demand.
For RoHS restricted substances and Threshold Limits, please consult the following list.
| RoHS Restricted Substance | Threshold Limit |
| Lead and compounds | 1,000ppm or less |
| Mercury and compounds | 1,000ppm or less |
| Cadmium and compounds | 100ppm or less |
| Hexavalent chromium and compounds | 1,000ppm or less |
| Polybrominated biphenyls (PBB) | 1,000ppm or less |
| Polybrominated diphenyl ethers (PBDE) | 1,000ppm or less |
Most of our products are RoHS compliant. However, there are some products that contain environmental impact substances with no alternative, since we manufacture products handling heat.
When ordering, please notify us as “RoHS product.”

The data mentioned above was compiled in July, 2006. |
Some of the glass material previously used for our sheath heaters contained lead, restricted under RoHS. Currently, however, newly developed glass sealing materials do not contain lead at all.
Please note that some products are not compliant with RoHS depending on the types of attached bushings and flanges. When ordering them, please mention this.
