The safe answer is no (unless otherwise is specifically specified on the packaging).
There can be small parts, or parts could break off and be small enough to generate a choking hazard but that is not the only reason to keep these “toys” away from children.
Urban Vinyl or collectable art toys not sold to children (targeted at ages 14 and older) do not need to undergo testing. Those toys targeted for sale to children must undergo testing certification and the packaging specifically call out is has passed such certification (normally in the fine print). Specifically this is the Children’s Product Certification (CPC). As a consumer, it is pretty safe to look for the target age on the package to confirm it is suitable for children.
Some have concerns that chewing on PVC (vinyl) may be bad for a child, but this is not where vinyl gets its bad reputation. PVC is hazardous from production to disposal and that is why it is sometimes referred to as “poison plastic”. There’s no safe way to manufacture, use or dispose of PVC products. PVC’s lifecycle uses and releases highly hazardous chemicals including dioxins and furans, vinyl chloride, ethylene dichloride, phthalates, mercury and other chemicals. The International Council of Toy Industries provides very specific claims that vinyl toys are safe on their website.
The risk of vinyl collectable toys getting in the hands of children is more tied to the possibility of the paint used containing lead. Testing of lead in the paint of toys is costly so toys not intended for children, especially those made in China may contain trace amounts of lead that could be dangerous if ingested.
The bottom line is, that these toys are not meant to be put in one’s mouth. Such is universally true for blind boxed and blind bagged collectables!
