A new sense of thrift is on the rise as house prices and bank balances fall. It seems to have prompted people to cash in their unwanted stuff. So it’s no surprise that, anecdotally anyway, there seem to be more garage, tag and stoop sales than ever.

Good for thrifty consumers on both sides of the cash box, you might say. True, but one caution for sellers: The same law that bars manufacturers from peddling a million lead-tainted toys applies to the tag-sale host selling just one. And it’s now illegal to sell any product that has been recalled.

The Consumer Product Safety Commission, which is in charge of enforcing the new safety law, (Consumer Product Safety Improvement Act) is offering buyers and sellers some guidance in the form of an illustrated booklet they can download.

Among the items that you cannot sell:

• Toys and other articles  intended  for  use  by  children, or any  furniture,  with  paint  or  other  surface  coatings  containing  lead  over  specified  amounts. 
• Products primarily intended for children age 12 or younger with lead content over a specific amount.
• Certain toys or child-care articles that contain any one of six prohibited chemicals known as phthalates.

The CPSC won’t be patrolling garage sales; a sense of responsibility should keep consumers from knowingly selling an item that could hurt someone, especially a child. So before you slap price stickers on the stash in your basement, check www.recalls.gov.

And if you’re shopping, we caution you not to buy a used crib, particularly one with drop sides or made before 1999. Also steer clear of car seats, play yards and any kids’ clothing with drawstrings.
