What is RoHS?

RoHS stands for Restriction on the use of Hazardous Substances. Currently, there are two major regional RoHS initiatives in effect:

  • European Directive 2011/65/EU - published in the Official Journal of the European Union.
  • Chinese Ministry of Information Industry Order #39 Management Methods for Controlling Pollution by Electronic Information Products, in effect on March 1, 2007.

These RoHS directives provide preventive measures on a legal basis to restrict the use of certain hazardous substances in various types of new electronic and electrical equipment.

Siemon Position

Siemon has achieved  compliance to these RoHS requirements. Specifically:

  • All Siemon products shipped to EU Member States from Siemon factories are fully RoHS compliant
  • Beginning March 1, 2007 all products shipped from Siemon factories to China comply to Chinese RoHS marking requirements
  • All Siemon products are shipped in packaging marked with the rhos-leaf-smallto signify EU RoHS compliance (when it applies) and the rhos-e-smallor rhos-fifty-smallto signify China RoHS status.
  • Some Siemon products are not electrical equipment. These items are not in the scope of RoHS and are not legally allowed to carry the CE logo. Packaging for these products will be marked with a leaf rohs-bw-leafor an arrow rohs-arrow, representing that these products do not contain any hazardous substances, as identified in the RoHS or REACH directives.

In respect to the vast quantity of part number databases owned and operated by our distributors, installers and customers and because many of our products have never contained these substances, we have decided not to change finished good part numbers to reflect compliant product. Specific compliancy requests can be directed to any regional Siemon sales office. For a list of regional contact information, please click here.

Restricted Substances

RoHS directives list the following six substances identified for restriction:

  • Lead (Pb)*
  • Mercury (Hg)
  • Cadmium (Cd)
  • Hexavalent Chromium (Cr-VI)
  • Polybrominated Biphenyls (PBB)
  • Polybrominated Diphenyl Ethers (PBDE)

*The EU RoHS directive provides an exemption for lead in solders for network infrastructure equipment for switching, signaling, transmission as well as network management for telecommunication. All EU RoHS compliant Siemon products being manufactured today do not use this exception and are 100% lead-free.

Siemon RoHS Compliant Product Labeling

Chinese Ministry of Information Industry Order #39 Management Methods for Controlling Pollution by Electronic Information Products, in effect on March 1, 2007 institutes marking requirements for product sold in China. Siemon markings are in compliance with these requirements

European Union Directive 2011/65/EU of the European Parliament restricts the use of certain hazardous substances in electrical and electronics equipment being sold into Europe. Siemon utilizes the CE mark to signify EU RoHS compliant product.
