Compliance is critical as these products often fall under both 'toys' and 'collectibles' categories. For the US market, products must meet ASTM F963-17 and CPSIA standards regarding lead content and small parts. For the EU, EN71 (Parts 1, 2, and 3) and CE Marking are mandatory. If the models include electronic components (like LED lights or sound), they must also comply with RoHS and WEEE directives. Always verify that the manufacturer holds official licensing agreements from car brands (e.g., Ferrari, Toyota, Ford) to avoid intellectual property infringement and customs seizures.
