FCC certification for products entering the US

Certification, for intentional radiators. Anything that deliberately transmits goes this way: the product is tested by a recognised laboratory and the authorisation is granted by an accredited certification body. The result is an FCC ID, which is published and searchable, along with the filing.

Supplier's Declaration of Conformity, for devices that emit only incidentally. The responsible party arranges testing to the applicable standards and declares conformity, keeping the documentation. There is no FCC ID and no public filing, which is exactly why buyers of hubs, docks, keyboards and stands are so often confused about what to ask for.

So the first question is which one applies to your product — and for a product with both a radio and high-speed digital circuitry, the answer can be both, covering different aspects.

What to ask for in each case. For a certified product: the FCC ID, and then look up the grant and the filing, because they are public. For a declared product: the test report against the applicable standard, the declaration, and the identity of the responsible party — who must be a party that can be reached in the United States.

Rule parts, emission limits, fees and timelines are deliberately not published here. They are procedural, they change, and a guide that reproduces them is a guide that becomes wrong quietly. What is stable is the structure above.

An FCC ID is composed of a grantee code assigned to a specific company followed by a product code chosen by that company. That means the identifier is a statement about who holds the grant, and it is public — the grant and its filing can be looked up, which makes this one of the very few compliance claims a buyer can verify independently in a few minutes.

Do that lookup. Search the ID, read the grantee name, and check it against the company you are buying from and the brand you intend to sell under. A mismatch is not automatically a problem — it is very often a module maker or a contract manufacturer — but it is a question you should be able to answer before you print anything.

Modular approval. A certified radio module can carry its own grant, and a host product using it is typically labelled to say it contains that module's FCC ID. What that permits depends on the module's approval conditions: some are granted on the basis that they may be integrated broadly, others carry conditions about antennas, enclosures, host circuitry or installation that must be met for the grant to apply.

So "the module is certified" is the beginning of the answer. Ask for the module's grant conditions and confirm that your product meets them, because a host that violates them is not covered by the module's grant and needs its own authorisation.

And a design change can break it. Changing the antenna, moving it, changing the enclosure material or altering the radio's configuration can all take a product outside the conditions of the grant it was relying on — which is another reason the antenna and enclosure belong in a specification with a change-notification clause.

The marking has to be on the product where practical, and it has to be legible and durable. Where the physical product is too small, the rules provide for alternatives, but "we could not fit it" is not one of them — decide the marking approach at the design stage rather than at packing.

A host containing a certified module is labelled to indicate the module's FCC ID. That label is a statement about which grant the product relies on, so it should match the grant you actually checked.

There has to be a responsible party who can be reached. For a declared product in particular, the declaration names a party responsible for compliance, and that party has to be locatable — which for a business outside the United States is a structural decision rather than a form.

And packaging and marketing claims are part of it. A product marketed with a capability that its authorisation does not cover — a frequency band, a power level, a mode — is a product whose paperwork and marketing disagree, and the marketing is what a customer buys.

As always, the obligation follows the brand: selling under your own name generally makes you the party answerable for what you place on the market, whatever the factory holds.

At quotation: ask which route the product is on, and for the FCC ID if it is certified. Look the ID up and read the grantee name.

Before the order: if a module is involved, ask for the module's grant conditions and confirm your product meets them — antenna type and placement, enclosure, host configuration. If it does not, budget for your own authorisation and for the time it takes.

In the specification: name the radio module and the antenna, and require notification of any change to either. This is the single clause that prevents a silent cost-down from invalidating your authorisation.

Before shipment: confirm the marking on the actual production units, not on a pre-production sample, and confirm that any "contains" labelling names the grant you verified.

And keep the documents. A marketplace, a customer or an enforcement enquiry arrives with a deadline, and a grant number you have not looked up is not evidence you hold.
