How do you calculate RoHS compliance coverage?

Divide confirmed-compliant parts by the total BOM count and multiply by 100. With 8 parts confirmed out of 250, coverage is 3.2%, leaving a 91.8-point gap to a 95% target.

What is a good RoHS coverage rate before shipping to the EU?

For a CE self-declaration you generally want 100% of in-scope components documented. Teams often set an internal gate like 95% to trigger final review, then close the last parts before release.

Does high RoHS coverage mean my product is compliant?

Not by itself. Coverage tracks how many parts have declarations on file. If a supplier declaration is wrong or a part exceeds a substance limit, the product can still be non-compliant despite showing full coverage.

What counts as a confirmed-compliant part?

A part backed by a valid supplier RoHS declaration, a compliant material declaration, or a test report against the RoHS substance limits. Verbal assurances or blank fields do not count toward the confirmed count.

RoHS coverage vs REACH coverage — what's the difference?

RoHS restricts ten specific substances in electrical and electronic equipment, while REACH covers a much broader SVHC list across all articles. Track them as separate coverage campaigns because the part scope and thresholds differ.

How do I close the gap to my RoHS target fast?

Prioritize parts by spend and by number of assemblies they touch, batch-request declarations from your highest-part-count suppliers, and accept manufacturer-level declarations where the part is on a documented compliant series.

Product Compliance, Labeling & Certification calculator

RoHS Compliance Coverage Calculator

RoHS Compliance Coverage tells you what share of the parts in a product's bill of materials have confirmed RoHS-compliant documentation, and how far that sits below your target. Compliance engineers, supply chain teams, and quality managers building EU-market electronics use it to track a declaration-collection campaign before a CE self-declaration or customer audit. RoHS (Restriction of Hazardous Substances) requires evidence that each component stays under limits for lead, cadmium, mercury, hexavalent chromium, and the phthalates added in RoHS 3. Since a single undocumented part can block a whole assembly from shipping to the EU, watching coverage climb toward 100% is a real gating metric.

What this calculator does

Estimate rohs compliance coverage for product compliance, labeling and certification using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.
Use it when rohs compliance coverage in product compliance, labeling and certification needs a clean rate and gap-to-target you can put on a tier board.
It computes confirmed-compliant parts as a percentage of the total BOM and reports the gap in percentage points to your target coverage rate.

Formula used

Rohs compliance coverage rate = rohs compliance coverage count ÷ total rohs compliance coverage population × 100
Rohs compliance coverage gap to target = rohs compliance coverage rate - target rohs compliance coverage rate

Inputs explained

Parts confirmed RoHS-compliant:
Total parts in the BOM:
Target RoHS coverage rate:

How to use the result

Use it while chasing supplier RoHS declarations to see how close a product is to full documented coverage before a CE declaration or audit.
It measures documentation coverage, not actual chemical compliance — a part counted as covered is only as trustworthy as the declaration or test report behind it.

Current U.S. benchmarks

The producer price index for paperboard and containers stands at 276.831 (BLS, May 2026), up 8.8% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 22,301 printing and related support establishments employing about 386,248 workers (Census County Business Patterns, 2023).
