The IRISO Group is committed to complying with the environmental laws and regulations of each country, such as the EU RoHS Directive and EU REACH Regulation, as well as to meeting the requirements of our customers. Our product chemicals management is based on practices at the supply chain level, and we have set up our "Green Procurement Standards" to ensure we and our suppliers play a part in the supply chain sustainable management. We are dedicated to the production of eco-friendly products by managing the green process from purchasing raw materials, and components and parts through manufacturing and shipping products. .
We have also installed an array of chemical analyzers and conducted periodic inspections to prevent the inflow and outflow of prohibited substances.
We ensure chemicals in products (CIP) are effectively managed across the entire supply chain. We are committed to communicating reliable information on chemicals in products.
We are committed to reducing risks associated with using chemicals, in compliance with environmental laws and policies in countries around the world, such as the EU RoHS Directive and the EU REACH Regulation.
・100% Ozone Depleting Chemical (ODC) Free Production
We started reducing the ODC substances in 1990 and achieved 100% DDC-free production by 1993. Since then, we have not used any ozone depleting chemicals (ODC) in manufacturing processes or for materials used in manufacturing.
・EU RoHS Compliance
In response to the EU RoHS Directive, aside from solder plating products requested by some of our customers, we have already demonstrated RoHS compliance. Four new restricted phthalates were added to the RoHS list in 2019, and we have not manufactured any products by using any of them since then.
・EU REACH Compliance
Since official REACH SVHC was published in November 2008, we have kept up to date with the latest REACH SVHC, which is updated once or twice a year. We also communicate information on chemicals in our products to customers on their request.
・Transition to Lead-Free Products
We started manufacturing lead-free products in 2000 and were already prepared to use lead-free alternatives for existing products by 2003. Since then, we have gradually shifted to lead-free manufacturing (excluding products requested by some of our customers). All products that have been newly developed since 2006 are lead-free. Consequently, 99.9% of the products delivered to our customers during the fiscal year 2022 are lead-free.
Since 2006, the group plants have started purchasing X-ray fluorescence analyzers (EDX), and all of them have it now. They use it for incoming and outgoing goods inspections. Other analyzers are owned by the IRISO group.
These analyzers enable us to confirm the non-inclusion of any RoHS 10 substances in the products so that we can ensure that harmful substances are not brought into the group plants during incoming inspections, to establish a quality assurance system that can build customer trust in the products, as well as performing a quick primary analysis when a product defect is found.

We ensure that all chemicals included in the PRTR (Pollutant Release and Transfer Register) list are properly managed through identifying and aggregating them based on the PRTR system to estimate chemicals handlings, emissions, and transfers, etc. Among chemicals in the PRTR list, nickel and nickel compounds, which are used in plating at the Ibaraki plant, are subject to legal reporting.
