In December 2013, the U.S. Consumer Product Safety Commission (CPSC) issued a consumer product safety standard for hand-held infant carriers. The standard incorporated by reference the applicable ASTM voluntary standard, with one modification in the definition of the product, to clarify that semi-rigid carriers fall within the scope of the standard. We are publishing this direct final rule revising the CPSC's mandatory standard for hand-held infant carriers to incorporate by reference the most recent version of the applicable ASTM standard.
