How It All Connects: The Compliance Landscape

A visual map of how international treaties, EU regulations, and data standards fit together, and how substance data flows from a supplier all the way to a CE mark.

Product compliance can look like an alphabet soup of RoHS, REACH, SCIP, POP, CLP, IEC and IPC. The underlying shape is simple. Law flows down, and data flows up to meet it.

The three tiers

International agreements set the direction. The EU turns them into binding regulations. Companies prove they comply by exchanging substance data through standard formats. Click any node to open its entry.

Tip

A few cross-links don't fit the neat tiers. CLP hazard classifications feed which substances become SVHCs under REACH, and the Waste Framework Directive is what created the SCIP database.

How substance data flows up to meet the law

Whatever the regulation, the underlying job is the same. Know what's in your product, declare it in a standard format, check it against the rules, and prove it.

1Know the composition
Suppliers report what's inside, ideally a full material declaration down to the homogeneous material.
2Declare in a standard format
Captured as IEC 62474 or IPC-1752A XML, declared against the right substance list.
3Check against the rules
Compare to RoHS limits, the REACH Candidate List, POP bans, and more.
4Prove it
CE mark and EU Declaration of Conformity (EN IEC 63000), plus a SCIP entry for any SVHC.
