A friend is considering importing a 15 volt Lithium-Ion Battery (2600mAh) operated tool from China to sell to consumers in the USA.

The battery charger that comes with the sprayer has a stamp that says that it is certified and it plugs into the wall socket. (see attached image below)

enter image description here

But the battery itself does not have any certification stamps, or any markings on it at all.

So what I am trying to find out is do they need to get the battery, or the tool itself certified by UL or some other safety certification before it can be legally sold in the USA, or is the charger the only component that is required to be tested and certified?

If the answer is yes, what kind of testing and certification is required to import it from China and to sell it here in the USA?

  • \$\begingroup\$ AFAIK, the "ETL" mark is the certification mark of Intertek. It is "equivalent" to a UL mark in that both are NRTLs (nationally recognized testing labs), and it indicates certification to the same standards, but by a different company than UL. \$\endgroup\$ – The Photon Jul 7 '17 at 4:32
  • \$\begingroup\$ Second, there's no legal requirement to carry a UL (or other NRTL) mark to be sold in the US. But many retailers might require it to carry a product. Also, if you don't have it and your product catches somebody's house on fire, you'll have a hard time showing you did your due diligence to make sure your product was safe. \$\endgroup\$ – The Photon Jul 7 '17 at 4:34
  • \$\begingroup\$ Thanks Photon. So as long as the charger has the ETL mark, then your saying that it shows that the company importing the product has done the proper due diligence to make sure that the product is safe... Right? \$\endgroup\$ – Henry Bockman Jul 7 '17 at 13:45

Due diligence with appropriate certification test reports are necessary for hazardous goods like LiPo packs with all the UN 38.3 test requirements set forth by United Nations.

Even if shipped by sea, there are risks to damage and supplier packaging test reports must include 1.2m drop tests on all sides and corners. (which may not be enough for some shippers.!)

Also get the UL test report for http://industries.ul.com/consumer-technology/batteries.

I would demand an ongoing Quality reliability verification program with measurable performance and safety parameters and consider large 3rd party liability insurance costs.
