# FCC · FCC authorisation

The mandatory US compliance requirement for radio-frequency emissions from electronic and electrical products. Depending on the category, the route is either Supplier's Declaration of Conformity (SDoC) or Certification, the latter granted by a TCB with an FCC ID.

| | |
|---|---|
| Issued by | SDoC is self-declared by the responsible party; Certification is granted by a TCB |
| Assessment route | Self-declaration |
| How it is obtained | Complete FCC Part 15 (or the applicable part) testing at a recognised laboratory. The Certification route requires an application with internal and external photos, block diagrams and the manual, and results in an FCC ID. The responsible party must be US-based. |
| Marking rules | SDoC products carry the compliance statement in the manual or on the product; Certification products must display the FCC ID. The FCC ID must not be used before authorisation is granted. |
| Validity and upkeep | Authorisations do not expire, but RF-relevant hardware or firmware changes require a permissive change or a new authorisation. |
