Changes to the rules governing lead content in children’s products have been unveiled by the US Consumer Product Safety Commission (CPSC).

Under the Consumer Product Safety Improvement Act of 2008, consumer products designed for children aged 12 and younger with a lead content of more than 100 parts per million (ppm) are considered banned hazardous substances under the Federal Hazardous Substances Act (FHSA).

Now the regulations provide for exception from the lead content limits under certain circumstances – if it is not practicable or technologically feasible to make the product without infringing the limits, or if the product is not likely to be put in the mouth of ingested, taking into account normal and reasonably foreseeable use.

However, the product in question must still have “no measurable adverse effect on public health or safety”, the CPSC said.
