New rules around testing and labelling of children's products sold the US are set to come into force from 8 February.

The Consumer Product Safety Commission will require "representative samples" of a product to be tested, replacing the previous need for "random sampling".

It also establishes a record keeping requirement associated with the testing of representative samples.

The new law also requires products to be tested periodically and when there has been a material change in the the product's design or manufacturing process, including the sourcing of component parts.

The manufacturer must document the procedure used to select representative product samples - as well as keep records documenting the testing of the samples, including the number of samples selected and the procedure used to select them.
