I'm pretty sure that dolls are called dolls if they have real cloth clothing instead of sculpted clothing.
So shit like OP and Hot Toys are called dolls by pretty much everyone.
Purely plastic toys like ML, Revoltechs, NECAs, Figmas, Transformers, Black Series, and such are all called action figures. So even figures that feature cloth goods are called dolls, because that cloth part is usually extraneous and overlaps the sculpted parts underneath.
Technically, every toy modeled after a human is considered a doll, even non-articulated green plastic men.
But no one knows about an early 1900 century tariff law that protected American made dolls because Europoors were making dolls for much cheaper.
The only toys not considered dolls in the US are XMen and other disgusting muties like Spider-Man.
>Toy Biz v. United States was a 2003 decision in the United States Court of International Trade that determined that for purposes of tariffs, Toy Biz's action figures were toys, not dolls, because they represented "nonhuman creatures".[1] This decision effectively halved the tariff rate, from 12 percent tax to 6.8 percenthttps://en.wikipedia.org/wiki/Toy_Biz,_Inc._v._United_States
