We are a access reader manufacturer outside of US. Do we need to obtain UL approval for our reader in order to sell or install in US?

NRTLs include ETL, CSA and others in addition to UL. Consumers are strongly encouraged to buy only listed and labelled products. Retailers are strongly encouraged to sell only such items. –  Nov 25 '20 at 14:00
  • UL and other NRTLs have offices in many countries. Listing requires periodic inspection of the manufacturer's facility. –  Nov 25 '20 at 14:03
