We previously covered the difference between RoHS and REACH. This article focuses specifically on how the RoHS Directive itself has evolved — many clients aren't clear on the difference between the "2.0" and "3.0" version labels.
Why RoHS Gets Version Updates
RoHS (Restriction of Hazardous Substances) isn't static — the EU periodically revises the restricted substance list and scope of application based on new scientific assessments and industry developments, and each major revision is typically accompanied by a version number update.
The Core Content of RoHS 2.0
RoHS 2.0 (corresponding to Directive 2011/65/EU), compared to the original RoHS 1.0, expanded the scope of applicable products (from a partial list of electrical/electronic products to nearly all electrical and electronic equipment), and required RoHS compliance as one of the prerequisites for a product to carry the CE mark.
The Core Change in RoHS 3.0
RoHS 3.0 (implemented via the amending Directive 2015/863), building on RoHS 2.0, primarily added 4 new restricted substances. Previously, RoHS restricted 6 substances (lead, mercury, cadmium, hexavalent chromium, PBB, PBDE) — RoHS 3.0 added 4 phthalates (DEHP, BBP, DBP, DIBP), bringing the total restricted substance count from 6 to 10.
Which Version Should You Test Against
RoHS 3.0 is the currently effective version for the EU market. New products exported to the EU should be tested against RoHS 3.0's requirements (10 restricted substances), not just the original 6. If the test report you have on hand only covers the older 6-substance version, it's worth checking whether it still meets current requirements.
Frequently Asked Questions
Q: Which types of products are most affected by RoHS 3.0's new phthalate restrictions? A: Phthalates are mainly found in plastic softeners (plasticizers), so products with significant plastic components (like cable sheathing or plastic housings) should pay particular attention to testing for these 4 newly added substances.
Q: Can an older product's old RoHS report still be used? A: If the report only covers the 6 substances from the RoHS 2.0 era and doesn't cover the 4 newly added phthalates, it's incomplete from a compliance standpoint — supplementary testing or a new report meeting RoHS 3.0 requirements is recommended.
If you're unsure whether your existing RoHS report meets current requirements, send it to us and we'll help check whether supplementary testing is needed.
