Full Breakdown

A used goods dealer under Chapter 41, Article VII covers stores, shops, and flea markets that buy, sell, barter, or exchange secondhand articles: separate license schemes cover junk dealers, pawnbrokers, precious metal dealers, scrap metal dealers, and used vehicle dealers. Licensed dealers must record every purchase in ink, including the seller's driver's license or state ID number, and hold that book open to police and BSEED inspection at any time. Dealers must tag each purchased item, hold it at least 15 days before resale, and post "Licensed Used Goods Dealer" over the shop door. Shops must not open before 7:00 a.m. or after 9:00 p.m. (11:00 p.m. Saturdays).

Violations & Fines

Violating any provision is a misdemeanor, punishable by up to $500 and 90 days in jail per violation; each day a violation continues can bring a separate charge, per Sec. 41-7-2.
