Who pays for HDMI certification — the factory or the brand?
Certification is applied per model by whoever owns the model; in OEM deals this must be written into the contract, not assumed.
Answer: the party that owns the model applies for its certification — so in a private-label deal, which side becomes the applicant (and pays for the ATC test) has to be agreed in writing.
Brand as applicant — the brand holds the certificate; changing factories does not require re-certification.
Factory as applicant — the factory holds it; if you switch suppliers, you may have to start again.
Either way, ask for the test report for the specific model, and check whose name is on it.
Cost figures vary by model and test scope — ask for a quote rather than a rule of thumb.
