Some IT/AV power products want to export to the United States for UL certification, but are troubled by not understanding the relevant certification requirements? The GTG editor has sorted out the relevant UL certification materials for you.
Is it mandatory certification
Not mandatory, but highly recognized in the United States.
Whether to detect the electromagnetic compatibility part
No, you can apply for FCC certification separately.
Do you need a local agent
Whether factory inspection is required
UL certification requires factory inspection. After applying for UL certification for the first time, an enterprise needs to conduct the first factory inspection before arranging shipments. The purpose is to ensure that the products continue to meet the requirements of UL certification and that all products produced are consistent with the test samples.
Subsequent certification does not require factory inspection before shipment. UL annual inspection is once a quarter, and a total of four factory inspections a year.
Information required for UL certification in the United States:
(1) CDF (Critical Parts List)
(2) Schematic diagram
(3) PCB Layout
(5) Transformer specifications, inductance specifications
(5) Model list/difference table
(6) Instructions for use or installation of the product, etc.
Note on product structure:
As for the cost of UL certification for the power supply products you are most concerned about, we need our colleagues in charge of certification to evaluate your products and quote you a price, and give you a reply within 15 minutes. Provide one-stop comprehensive services such as product evaluation, forecasting, testing, rectification, and factory inspection.
