The most plug-specific category there is: national plug laws are hard requirements, and USB models add charger rules.
Socket-outlet products are regulated closer to components than to consumer gadgets: national plug and socket standards are legally binding in their home markets, and a wrong plug type is a customs problem before it is a safety problem. The UK's fused-plug law is the classic example.
Modern strips are also chargers: USB-C PD outputs bring the external-power-supply and efficiency rules into scope alongside the socket standards.
| Market | Typical requirements | Notes |
|---|---|---|
| United States | UL/ETL listing to UL 1363 (portable power strips) or UL 1449 (surge protectors); FCC Part 15 Subpart B for electronic models | NRTL listing is the de-facto retail requirement for anything with mains outlets |
| European Union | CE: LVD with socket/plug standards (EN 60884 family for plugs and socket-outlets); USB outputs per EN 62368-1; EMC; RoHS | Adapters sold as travel accessories still need destination-market plug conformity |
| United Kingdom | BS 1363 fused plug requirements under the Plugs and Sockets (Safety) Regulations - legally mandatory | Non-compliant plugs are a customs seizure, not a fine-tuning item |
| USB-equipped models | External power supply rules (DOE Level VI for the US, ErP 2019/1782 for the EU) where applicable | The USB output is a charger in the eyes of the regulator |
Selling power strips or travel adapters into the US, EU or UK? Send the plug types and USB configuration - we will build the scope across socket, charger and surge requirements.
The Plugs and Sockets (Safety) Regulations make BS 1363 conformity (including the fused plug and approved plug design) legally mandatory for plugs intended for UK sockets. Non-conforming plugs are stopped at the border - there is no 'fix it later' path.
Functionally yes: the socket side follows plug/socket standards and the USB side follows charger rules - safety (62368-1), EMC and efficiency (DOE/ErP where applicable). A complete quotation covers both.
Yes - surge-protective models are assessed to UL 1449 (US) or the equivalent route elsewhere, with let-through voltage and clamping performance verified, not just the mechanical socket tests.
