RoHS certification is required for exporting, manufacturing and importing goods in RoHS compliant regions, such as Asian nations (including China, Japan, and South Korea) as well as versions of it in North America. RoHS certification is especially essential for companies involved with RoHS compliant or RoHS parallel importing. RoHS compliance requirements also apply to all product suppliers, including original equipment manufacturers (OEMs), original design manufacturers (ODMs) and subcontractors.
