RoHS 2 or RoHS 3: What’s the Difference (and which Certificate Should you Accept)?
If you’ve ever received a supplier declaration labeled “RoHS 3” and wondered whether it’s “newer” (or more valid) than RoHS 2, you’re not alone.
Here’s the key point:
So, in practice, “RoHS 3” is not a separate, standalone directive—it’s commonly shorthand for an important update within the RoHS 2 framework.
-
RoHS 1: 2002/95/EC (legacy directive, replaced)
-
RoHS 2: 2011/65/EU (the main directive you comply with today)
-
“RoHS 3”: common industry nickname for Directive (EU) 2015/863, which amended RoHS 2 by expanding the restricted substances list
-
For supplier declarations: you don’t need a document literally titled “RoHS 3” as long as it clearly demonstrates compliance with the current restricted substances list under 2011/65/EU (as amended).
EU RoHS compliance is anchored in Directive 2011/65/EU. Over time, that directive has been updated through multiple amendments. The amendment most people remember is 2015/863, because it expanded the restricted substances list—so people started saying “RoHS 3.” But legally speaking, you’re still operating under the RoHS 2 framework (2011/65/EU), just with amendments applied.
Why do People Say “RoHS 3” at All?
RoHS Timeline (Simple)
RoHS 1 — the Starting Point
The original restriction framework came from the first RoHS directive (commonly referred to as RoHS 1), which was later replaced.
RoHS 2 — the Core Directive in Force
Directive 2011/65/EU is the current legal backbone of EU RoHS compliance and is often called RoHS 2 (recast).
“RoHS 3” — a Major Amendment to RoHS 2
Commission Delegated Directive (EU) 2015/863 updated RoHS 2 by amending Annex II (restricted substances list).
What Substances are Restricted under EU RoHS Today?
Under RoHS 2 (as amended), the commonly referenced Annex II list includes 10 restricted substances. The limits apply at the homogeneous material level (i.e., the smallest material you can mechanically separate).

Does EU RoHS Apply to your Product?
EU RoHS targets electrical and electronic equipment (EEE) placed on the EU market, and the European Commission summarizes the directive’s purpose as reducing risks to health and the environment by restricting certain hazardous substances in EEE.

So… Should you Require a “RoHS 3” Certificate?
Not necessarily.
What you actually want is a declaration that confirms compliance with:
A supplier document titled “RoHS 2” can still be acceptable if it clearly covers the current restricted substances list and is written in a way that aligns with EU RoHS compliance expectations.
Supplier must confirm compliance with EU RoHS Directive 2011/65/EU, as amended (including Directive (EU) 2015/863), at the homogeneous material level, and provide supporting technical documentation upon request.
What RoHS Actually Stands for (Quick Refresher)
RoHS is shorthand for: Restriction of Hazardous Substances in electrical and electronic equipment—i.e., limiting certain substances used in EEE to reduce environmental and health risks.

Need Help Validating Supplier RoHS Declarations?
If you’re unsure whether a certificate is sufficient (or you want to audit the supply chain and back up compliance with solid documentation), we can help you verify RoHS status—especially when suppliers use inconsistent “RoHS 2 / RoHS 3” wording.
