2.1.3 European Union Restriction of Hazardous Substances (RoHS)
The European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemical sub-
stances, including Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE, in electronic products, effective
July 2006. This drive is manufactured with components and materials that comply with the RoHS Directive.
A number of parts and materials in Seagate products are procured from external suppliers. We rely on the representa-
tions of our suppliers regarding the presence of RoHS substances in these parts and materials. Our supplier contracts
require compliance with our chemical substance restrictions, and our suppliers document their compliance with our
requirements by providing material content declarations for all parts and materials for the disk drives documented in
this publication. Current supplier declarations include disclosure of the inclusion of any RoHS-regulated substance in
such parts or materials.
Seagate also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws and reg-
ulations which restrict chemical content in electronic products. These systems include standard operating procedures
that ensure that restricted substances are not utilized in our manufacturing operations, laboratory analytical valida-
tion testing, and an internal auditing process to ensure that all standard operating procedures are complied with.
