Terahertz Wellness Devices: A Certifications and Compliance Checklist for Importers

If you are planning to import terahertz or thermal wellness devices into a new market, the checklist goes well beyond customs classification. This is a starting point — always confirm specifics with a licensed customs broker or regulatory consultant in your target market, since requirements vary by country and can change.

Electrical safety certification

Most markets require some form of electrical safety certification before a powered device can be sold at retail — CE in the EU, UKCA in the UK, FCC in the US (for electromagnetic emissions specifically, separate from electrical safety), and equivalents elsewhere. Confirm your supplier's certificates cover your specific product model and voltage configuration, not just a similar model in their lineup — a certificate issued for a 110V version does not automatically cover a 220V variant of the same product family, even if the internal design is nearly identical.

It is also worth confirming who the certificate is issued to. A certification issued directly to your supplier's factory, versus one issued to a trading company reselling that factory's output, can matter if the certification is ever questioned by a customs authority — request a copy of the actual certificate, not just a claim that "we are certified."

Health-product advertising rules

Many countries regulate what can be claimed about health and wellness products in advertising, independent of the device's electrical safety certification. Claims about "curing," "treating," or "preventing" medical conditions are heavily restricted or prohibited in most jurisdictions unless the product has gone through medical-device clearance — and that clearance process is a categorically different (and typically far more expensive and time-consuming) undertaking than electrical safety certification. Stick to descriptive, physical claims (temperature, ion output, wattage) rather than therapeutic outcomes in your own market's advertising, as covered in our sales team training guide.

This applies to more than your own website copy — it extends to how your sales team talks about the product verbally, how resellers downstream of you describe it, and any translated marketing material. A claim that would be flagged in English does not become safe simply because it is translated into another language for a different market.

Documentation to request from your supplier

• Certificate of Conformity (CE/UKCA/FCC/equivalent) with the specific model number listed
• Third-party lab test report (frequency output, noise level, rated lifespan)
• Material safety information, especially for any component in direct skin contact
• Patent registration documents, if you plan to reference "patented technology" in your own marketing
• A copy of the product's own user manual and safety warnings, which customs in some markets will ask to review directly

Working with a customs broker

Wellness devices sometimes get classified differently depending on how they are described on import paperwork (as a "personal care appliance" vs. a "medical device," for example, or under different HS code headings depending on function and construction — see our in-depth HS code classification article) — the classification affects duty rates and which certifications customs will ask to see. This is worth getting right with professional advice before your first shipment, not after a shipment is held at customs while the classification gets sorted out retroactively.

Building a per-market compliance file

Rather than treating compliance as a one-time check before your first order, it is worth keeping a simple per-market file: which certifications apply, which your supplier currently holds (with copies), what advertising language is restricted, and who your customs broker contact is. This becomes genuinely useful the moment you add a second product or expand to a second market, since you are not starting the research from zero each time.
