Kites are often classified as toys or sporting goods. For the US market, they must comply with ASTM F963 (Standard Consumer Safety Specification for Toy Safety), specifically regarding string strength and small parts. For the EU, EN71-1, 2, and 3 certifications are mandatory to ensure mechanical safety, flammability resistance, and the absence of toxic chemicals in dyes. Additionally, ensure the kite line does not contain metallic components to prevent electrical conductivity risks, which is a major regulatory requirement in many regions.
