Direct Answer
Only say "UL Certified" for a CCS1 to Tesla adapter if that exact model holds a valid, current UL certification issued through a recognized testing body, and you can produce the certificate and inspection report on request.
Available public documentation for some CCS1 to NACS/Tesla adapters may show FCC and CE evidence rather than UL certification. This is not a rule for all products. UL status must be verified for the exact model, market, and sales channel.
For the YIYANG SHENDA CCS1 to NACS adapter model ST-E007, available product documentation lists FCC and CE marks. UL status is not documented for that model. A "UL Certified" claim should not be made for ST-E007 without a valid UL certificate tied to the specific model and market.

Key Takeaways
- Marketplace and channel rules - online platforms, retailers, and distributors may ask for certification documents tied to the exact model.
- Import and liability - an unsupported "UL Certified" claim can create compliance, insurance, and liability exposure for the importer or brand owner.
- Project and installer requirements - charging operators, fleet buyers, and public projects often require documented certification before approving a product.
- Brand trust - overstating certification is one of the fastest ways to lose channel confidence once a buyer requests the certificate number.

Detailed Answer
"UL Certified" is not a generic quality label. It refers to a specific North American safety certification process.
Key distinctions buyers and sellers should keep separate -
For a DC high-power adapter such as a CCS1 to Tesla/NACS unit, commonly referenced North American standards in the industry may include UL 2251 for connectors, UL 2594 for EV supply equipment, and UL 2231 for protective devices. Which standard applies depends on the product function and the route to market. These are general industry references only. The correct standard and certification pathway must be confirmed for the specific adapter, market, and sales channel.

A certification claim affects sourcing risk, not just marketing.
Buyers should treat certification wording as a verification item, not a marketing phrase.

FAQ
Is FCC the same as UL certification?
No. FCC relates to electromagnetic compatibility. UL certification is a separate safety listing process.
Can I say "UL Certified" if my supplier has a UL certificate for a different product?
No. The claim should only apply to the specific model listed on the certificate.
Can I say "UL compliant" or "UL tested" instead?
Only if you can support that wording with an actual inspection report or assessment. Vague substitutes can still create compliance risk.
What is a safe way to describe a CCS1 to Tesla adapter's certification?
A conservative expression is - "FCC and CE documents are available for selected models. UL status should be confirmed by model, market, and sales channel."
Does every CCS1 to Tesla adapter require UL?
Not necessarily for every market or channel. The requirement depends on the target country, the buyer type, and the platform or project rules. This should be confirmed case by case.
Does the adapter work with all Tesla vehicles and all CCS1 chargers?
No. Compatibility depends on the vehicle-side connector, vehicle year, the charger-side output, and the DC scenario. It should be verified, not assumed.
What if my target market is Europe, not North America?
Certification framing changes by region. European buyers typically review CE-related documents. North American buyers focus on UL, ETL, or other NRTL listings depending on the channel. ---
