Why Import Certifications Are Becoming a Bigger Factor in Lighting Purchase Decisions

As more and more US commercial and industrial buildings transition to LED, certification has become an important consideration before placing an order. Buyers often ask "What certifications are needed for LED lights imported from China to the USA?" before moving ahead, especially because utility rebate programs and local building codes can tie eligibility to specific certification standards.

UL listing is still the most recognizable safety certification for lighting products entering the US market. UL testing includes electrical safety, fire safety and construction requirements. Most electrical inspectors and building departments require fixtures to be UL listed before an installation is approved – whether or not the project qualifies for any rebate program.

DLC certification is managed by the Design Lights Consortium and has become as important for commercial and industrial projects as it directly ties to utility rebates. DLC's Qualified Products List has a standard listing and a Premium tier, which usually requires a higher level of efficacy and more stringent performance thresholds. This certification is not only a technical consideration, but a financial one as well, as many utility rebate programs across the country will only reimburse for fixtures that are listed on the DLC QPL.

FCC certification is a whole other matter: electromagnetic interference. LED drivers, especially dimmable drivers, can produce electrical noise that can interfere with radio equipment or other electronics, and FCC compliance ensures a fixture's emissions are within acceptable limits for the U.S. market.

ETL certification is very similar to UL in that it is a nationally recognized testing laboratory mark and is accepted as an equivalent alternative in most jurisdictions. Some buyers think ETL is a lower standard than UL. They're actually part of the same OSHA Nationally Recognized Testing Laboratory program and either mark is acceptable for code compliance purposes.

While more commonly associated with the European Union, RoHS compliance is increasingly being requested by US buyers, especially those working with corporate sustainability requirements or California's own restrictions on hazardous substances in electronics. RoHS certifies that a product does not contain more than certain levels of substances like lead, mercury and cadmium in its construction.

Energy Star certification is for a smaller number of residential fixtures and some commercial fixtures. Energy Star is not required for most commercial projects but it can help qualify for more rebates in some programs where there is overlap between Energy Star and DLC requirements.

Import documentation is not just the product certification. US Customs and Border Protection requires correct classification of products, and buyers should make sure that shipping documents, including any FCC supplier's declaration of conformity, are properly prepared to avoid delays at the port of entry.

Industry observers say buyers who check these certifications before placing an order — not after a shipment arrives — avoid the most common and costly compliance problems: customs delays, rejected rebate applications and installations that don't pass local electrical inspection. As commercial lighting procurement becomes more standardized around these requirements, certification documentation has effectively become as important a factor in supplier selection as price or lead time.
