It's not just about GCC's ...............

The visible implications of the CPSIA act are many and often expensive for many organizations: GCC's, labels, use of independent lab testing etc.

But much of the act is based on science, engineering and shop floor manufacturing. For example see
"Interpretative Rule on Inaccessible Component Parts" and "Testing of Component Parts".
To operate profitably and compliantly under CPSIA, organization with need understand the science and engineering implications of their processes. This means upgrading the skills of their staff or engaging consulting expertise as required.
