Toys safety specifications

Seeking everyones help with this.

Firstly I want to start selling under this said category: Toys & Games > Stuffed Animals & Plush Toys. Is this specific category gated? And If so what are my actions as a seller to ungate said category, who wants to bring my own product onto the market?

Going further with gating and safety specifications. What is the main difference between gating and compliance? How frequently is CPC needed when dealing with compliances? How consistently or on what occasions does the product have to be tested for CPSIA and ASTM F963-17?
