For 35 years, William John Woods has made wooden toys for children. Each one of the 2,000 or so he makes each year passes through his hands at his shop in Ogunquit, Maine, and no child, he said, has ever been hurt by one of his small boats, cars, helicopters or rattles.

But now he and others like him  makers of small toys and owners of toy resale shops and boutique stores  say their livelihood is being threatened by federal legislation enacted in the last year to protect children from toxic toys through more extensive testing. Big toymakers, including those whose tainted imports from China led to the recall of 45 million toys and spurred Congress to take action, have more resources and are able to comply with the new law’s requirements.

“This is absurd,” said Mr. Woods, whose toys are made of maple, walnut and cherry and finished with walnut oil and beeswax from a local apiary. He estimates it would cost him $30,000  a figure he calculated from having to pay $400 in required tests for each of the 80 or so different items he produces  to show that they are not toxic.

“I use beeswax,” Mr. Woods said. “The law was targeted at large toymakers using lead. There was no exclusion for benign products.”
