The Restriction of Hazardous Substances Directive 2011/65/EC ( RoHS 2)

As of June 8, 2011 certain heavy metals and brominated fire retardants have been restricted in electronic and electrical equipment marketed in the European Union. On March 31, 2015 this list was amended to include some phthalates used in medical devices. Lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers, Bis(2-ethylhexyl) phthalate, Butyl benzyl phthalate, Dibutyl phthalate and Diisobutyl phthalate are subject to threshold levels established by Directive 2011/65/EU of the European Parliament and of the Council of June 8, 2011 with amendment 2015/863 of the Commission of March 31, 2015 on the restriction and use of certain hazardous substances in electrical, electronic equipment, and medical devices.

The term 'RoHS Compliant' has been popularized to refer to products that comply with the restrictions. The overwhelming majority of wire products produced and supplied by MWS Wire Industries are in compliance with the EC directive. We will continue to supply solder plated wire containing lead and cadmium plated and cadmium copper alloy wire to our customers that want and need these products. All products sold exceeding RoHS threshold levels of lead or cadmium carry a RoHS non-compliance statement on the packing slip, certification and invoice so any MWS customer can determine if they have purchased a product containing lead or cadmium above the threshold level. A guide including key words and specification indicators is also available in this section. Select the link 'Products Containing Cadmium or Lead' at the bottom of this page to access this guide.

RoHS compliance certifications are supported with compliance declarations and data from suppliers. MWS has also submitted samples of magnet wire insulating materials to an independent NELAP certified laboratory for analyses for restricted substances. The results of these analyses may be accessed by selecting the 'Analytical Data' link at the end of this page.

If you need a RoHS Certificate of Compliance for the products you purchase from MWS, please contact our sales department for a prompt response to your request or e-mail:
