How it works

Five steps from an inquiry to a registered certificate

Typical timeline6 to 16 weeks including FCC

  1. You send the request

    Product name, HS code and technical data, enough for us to scope the route.

    Your part
  2. We confirm the route

    A specialist confirms the regulations that apply and the document type your product needs.

    Our part
  3. Documents and contract

    You send the supporting documents; we sign a contract with fixed scope and timeline.

    Both sides
  4. Testing and inspection

    Laboratory testing, factory inspection and customs clearance, coordinated by us.

    Our part
  5. You receive the certificate

    Issued, registered, and delivered. We close the project.

    Your part
  • One named specialist One person owns your file from the first email to the registered certificate.
  • Route fixed before testing Scheme, standard and laboratory are settled before a sample is tested, which is where most re-testing starts.
  • Registered documents Certificates and declarations issued by accredited bodies and entered in the official register, where customs can look them up.
  • Measured by the document The engagement ends when the certificate is issued and registered, whatever the hours took.
The short answer

Safety listing and radio approval are separate files

UL certification is what buyers ask for; the legal requirement is listing by a Nationally Recognized Testing Laboratory. UL certification is what buyers ask for, but the legal requirement behind it is listing by a Nationally Recognized Testing Laboratory under OSHA rule 29 CFR 1910.7, and UL is one of several. An Intertek (ETL) or CSA listing to the same UL standard satisfies the same rule. Radio and electromagnetic behaviour is a separate federal obligation under 47 CFR Part 15, administered by the FCC, and a product with a radio needs both.

  • OSHA rule 29 CFR 1910.7 The requirement comes from OSHA, which recognises several such laboratories under this rule. UL is one of them.
  • ETL or CSA counts the same An Intertek (ETL) or CSA listing to the same UL standard satisfies the same rule.
  • Radio is a separate federal file Radio and electromagnetic behaviour is a separate federal obligation under 47 CFR Part 15, administered by the FCC.
  • A radio product needs both A product with a radio needs the NRTL listing and the FCC authorisation.
  • Any NRTL listing

    OSHA rule 29 CFR 1910.7 recognises several Nationally Recognized Testing Laboratories, and UL is one of them. An Intertek (ETL) or CSA listing to the same UL standard meets the same obligation.

    Check whether a customer contract names UL before you choose the laboratory.

  • The standard decides

    The standard fixes the test programme: UL 60335-1 for household appliances, UL 62368-1 for audio, video and IT, UL 61010-1 for laboratory equipment, UL 508A for industrial control panels.

    Confirm on the OSHA NRTL list that the laboratory is recognised for that standard.

  • FCC Part 15

    Wi-Fi, Bluetooth or cellular makes the product an intentional radiator under 47 CFR Part 15 Subpart C. It needs FCC certification through a TCB and an FCC ID, separately from any NRTL listing.

    A module grant carries over only inside its antenna, placement and output-power conditions.

Already started elsewhere

UL listing or FCC ID stuck halfway with another provider?

The laboratory may hold NRTL recognition for a different standard from yours, because OSHA grants recognition per standard and per site. Or a customer contract names UL, and the ETL listing already paid for does not meet it. A radio module fitted with a different antenna is no longer covered by its grant. And an appliance missing from California's MAEDbS database cannot be sold there whatever its federal status.

A listing has no fixed expiry. It continues while the product stays unchanged and the factory passes its follow-up inspections, four a year under the UL programme, and a change to a safety-critical component needs re-evaluation. A laboratory without recognition for your standard cannot list the product to it. The FCC side is separate: a module grant can be reused under 47 CFR 15.212 only within its written conditions, and outside them the authorisation is yours to obtain.

What we handle

  • Standard selection
  • NRTL testing
  • FCC authorisation
  • Factory audit

What to send us

Everything here is something to find before the project starts. The first reply says which of it can go into the file as it is.

  • The product, its schematics and the critical component list, as the laboratory last saw them
  • The UL standard the product was tested to, and the laboratory that tested it
  • The FCC ID or module grant, with the antenna and placement you used
  • Any customer contract clause or specification that names UL

What does "UL certification" mean?

Buyers, inspectors and specifications say "UL listed" as shorthand for any third-party safety listing. The requirement behind the phrase comes from OSHA. 29 CFR 1910.7 sets out how a laboratory becomes a Nationally Recognized Testing Laboratory, and 29 CFR 1910.303(a) requires electrical equipment in the workplace to be approved, which an inspector reads as listed by one of them. UL is the best known and wrote most of the standards tested against, but the listing can come from any NRTL recognised for that standard.

The standard is what fixes the test programme. A household appliance is tested to UL 60335-1 with its part 2, an audio, video or IT product to UL 62368-1 (UL 60950-1 was withdrawn in December 2020), laboratory and measuring equipment to UL 61010-1, and an industrial control panel to UL 508A. A manufacturer told they need "UL" can often meet the requirement sooner through another NRTL testing to the same UL standard. The mark differs; the legal standing does not. Where that stops working is a customer contract naming UL by name, and that is a commercial negotiation.

Do you also need FCC authorisation?

Anything that intentionally radiates radio frequency energy (Wi-Fi, Bluetooth, cellular, any transmitter) is an intentional radiator under 47 CFR Part 15 Subpart C. It needs FCC certification through a Telecommunication Certification Body before it is marketed in the United States, and it carries an FCC ID. This is federal and independent of any NRTL listing.

Digital devices that do not transmit fall under the unintentional radiator rules in Part 15 Subpart B, and most of them use the Supplier's Declaration of Conformity route under 47 CFR 2.906, with no FCC ID. Which route applies is decided by what the device does with radio frequency energy. Complexity has nothing to do with it. A product built on a pre-certified module can reuse the module grant under 47 CFR 15.212, but only inside the antenna, placement and output-power conditions written on that grant.

The parts nobody mentions until late

Energy efficiency is a real barrier for appliances and external power supplies. The Department of Energy sets minimum standards in 10 CFR Parts 430 and 431, the FTC runs EnergyGuide labelling under 16 CFR Part 305, and California adds its own Title 20 appliance regulations with a registration database, MAEDbS. A product missing from that database cannot be sold in California whatever its federal status.

There is also no single national authority for installed equipment. The authority having jurisdiction, usually a local electrical inspector applying the National Electrical Code (NFPA 70), decides whether an installation is acceptable, and the reference point in NEC 110.3(B) is the listing mark and the listing instructions. An unlisted product can be technically safe and still be rejected on site.

NRTL recognition under 29 CFR 1910.7 is granted per standard and per site. A laboratory recognised for one product standard is not automatically recognised for another; confirm scope on the OSHA NRTL list before booking testing.

Frequently asked questions

Is UL certification legally required in the United States?

UL specifically is not. What OSHA requires under 29 CFR 1910.303 for workplace and installed electrical equipment is approval by a Nationally Recognized Testing Laboratory, and OSHA recognises several under 29 CFR 1910.7. An ETL or CSA listing to the same UL standard meets the same obligation. The exception is a customer contract that names UL, which is a commercial term and has to be negotiated as one.

What is the difference between UL Listed and UL Recognized?

A Listed mark applies to a complete product ready for installation or use as it stands. A Recognized Component mark applies to a part intended to be built into something else, and carries conditions of acceptability describing how it may be used. A product assembled entirely from recognised components is still not itself listed; the finished assembly needs its own evaluation.

Do I need an FCC ID for a product with Bluetooth?

Yes. Bluetooth is an intentional radiator under 47 CFR Part 15 Subpart C, so the product needs FCC certification and an FCC ID. If it uses a pre-certified radio module you may rely on the module grant under 47 CFR 15.212, but only within the conditions the module maker specifies: the antenna type, its placement and firmware control of output power. Change any of those and the authorisation becomes yours to obtain.

How long does an NRTL listing stay valid?

There is no fixed expiry. The listing continues while the product is unchanged and the factory passes follow-up inspections, four a year under the UL programme. Design changes to safety-critical components need re-evaluation, which is far quicker than the original submission but is not optional.
