We don't certify your product — we help you assemble the compliance evidence file buyers, platforms and customs actually ask for: a Declaration of Conformity, a risk assessment, and a required-marks checklist. Electronics-first (CE / EMC / RoHS / WEEE / GPSR / FCC).
The blue mark is a free visual byproduct once your files are assembled. It is NOT a certification claim — ListingGood is not a certification body, and the mark never goes on your Amazon product image (Amazon policy Error 18729).
ListingGood assembles your evidence files; it does not certify products. Final responsibility for accuracy rests with the manufacturer / importer.
