In most cases, more than one ASTM standard (or parts) applies to a certain product. Here is one example:
ASTM F963-17-Toys-Mechanical Hazards
ASTM F963-17-Toys-Flammability of Solids
ASTM F963-17-Toys-Soluble Heavy Metals Content
CPSIA Section 101-Children’s Products-Total Lead (Pb) Content
The good thing is that you as an importer don’t need to make this assessment yourself. Instead, you can ask a CPSC approved lab testing company such as GIG for a quotation, in which case we present our assessment for your products (e.g. a list of ASTM standards).
