UL 498 Buyer Checklist (PDF)
A one-page screening tool for North American distributors, contractors, and import buyers reviewing receptacle orders ahead of the June 20, 2026 effective date.
Why this exists: UL 498 changes take effect June 20, 2026. Listing reports not reviewed against the new revision are withdrawn on that date. This one-page checklist is what buyers send their suppliers this week to make sure July shipments still have valid paperwork.
