RoHS Compliance Checker
Free RoHS compliance checker: paste a product's substance data and get an instant pass/fail against the 10 RoHS-restricted substances. Runs in your browser.
Use this RoHS compliance checker to paste a product’s declared substance concentrations and get an instant read on whether it stays within the RoHS restricted-substance limits. It is built for distributors enriching supplier records who need a fast, repeatable sanity check before a compliance flag goes into the catalog.

The checker evaluates a homogeneous material against the restricted substances defined by the EU RoHS Directive (2011/65/EU, as amended) and flags anything over the maximum concentration value tolerated by weight.
- All ten currently restricted substances: lead, mercury, cadmium, hexavalent chromium, PBB, PBDE, and the four added phthalates (DEHP, BBP, DBP, DIBP).
- Each declared concentration against its threshold, expressed as a percentage by weight in homogeneous material.
- The lower cadmium threshold, which is stricter than the limit applied to the other nine substances.
- Unit and format consistency, so a value entered in ppm is compared correctly against a percentage limit.
- Missing or unparseable substance rows, so an incomplete declaration is surfaced rather than silently passed.
- A plain-language pass, fail, or “insufficient data” verdict per substance and an overall result for the record.
How the RoHS compliance checker works
RoHS restricts the concentration of specific hazardous substances in electrical and electronic equipment. Nine substances share one maximum concentration ceiling; cadmium carries a lower one. The limits apply at the level of homogeneous material — a single material that cannot be mechanically separated — not at the level of the finished product, which is why a supplier sheet usually lists values per component or per material.
- 1Paste your declarationEnter substance names and concentrations from a supplier’s RoHS declaration, lab report, or material data sheet.
- 2Normalize the unitsThe tool converts ppm and percentage values to a common basis before comparison.
- 3Compare to thresholdsEach value is checked against the limit for that substance, applying the stricter ceiling for cadmium.
- 4Read the verdictYou get a per-substance and overall pass/fail, plus a note on any row that could not be evaluated.
Everything runs locally in your browser. Nothing is uploaded, so you can run confidential supplier declarations — whether for industrial MRO components, a furniture range with electronic fittings, or a CPG item with a powered accessory — without the data leaving your machine. The same logic generalizes beyond electrical-only catalogs: any record claiming a RoHS status, from a powered tool to a battery-equipped consumer good, can be screened the same way.
| Substance group | Concentration ceiling |
|---|---|
| Lead, mercury, hexavalent chromium, PBB, PBDE, DEHP, BBP, DBP, DIBP | 0.1% by weight in homogeneous material |
| Cadmium | 0.01% by weight in homogeneous material |

FAQ
What substances does RoHS restrict?
RoHS currently restricts ten substances: lead, mercury, cadmium, hexavalent chromium, two brominated flame retardants (PBB and PBDE), and four phthalates (DEHP, BBP, DBP and DIBP). Nine share a 0.1% ceiling by weight in homogeneous material; cadmium is held to a stricter 0.01%.
What is the maximum concentration value for RoHS compliance?
For nine of the ten substances, the maximum tolerated concentration is 0.1% by weight in any homogeneous material. Cadmium has a lower limit of 0.01%. The threshold applies to each separable material, not to the average across the whole product.
Is RoHS the same as REACH?
No. RoHS restricts a fixed list of hazardous substances in electrical and electronic equipment. REACH is a broader chemicals regulation with an evolving SVHC candidate list and separate notification duties. A product can satisfy RoHS and still carry REACH obligations, which is why many distributors screen against both. Use the SVHC Candidate List Checker for the REACH side.
Does the checker upload my supplier declarations?
No. All processing happens client-side in your browser. Your pasted or uploaded substance data is never sent to a server, so confidential supplier sheets stay on your machine.
Can a RoHS pass be applied to a whole catalog automatically?
Screening one record at a time is useful for spot checks, but applying a verified RoHS status across thousands of SKUs needs source documents, unit normalization, and a provenance trail on every field. That is the kind of enrichment Claro automates, keeping a link back to the supplier declaration behind each compliance value.
