The Consumer Product Safety Commission (CPSC) is issuing a final rule determining that certain unfinished manufactured fibers do not contain the ASTM F963 elements or specified phthalates that exceed the limits set forth under the CPSC's statutes and regulations for children's toys and child care articles. Based on these determinations, the specified unfinished manufactured fibers would not be required to have third party testing for compliance with the requirements of the ASTM F963 elements or phthalates for children's toys and child care articles.
