When sourcing Eva Gun Toys, the primary concern is the chemical composition of the EVA (Ethylene-Vinyl Acetate) foam and the plastic body. You must ensure the products are BPA-free, non-toxic, and phthalate-free. For the US market, compliance with ASTM F963 is mandatory, while the EU market requires EN71 (Parts 1, 2, and 3) certification. Always request Material Safety Data Sheets (MSDS) to verify that the foam projectiles do not contain hazardous substances that could be harmful if they come into contact with skin or are accidentally ingested.
