Safety is the highest priority in children's apparel. You must ensure products comply with CPSIA (USA), REACH (EU), or GB standards (China). Specifically, verify that all fabrics are OEKO-TEX Standard 100 certified to ensure they are free from harmful chemicals. For infants, pay close attention to small parts (buttons, sequins) which must pass pull-tests (typically 90N for 10 seconds) to prevent choking hazards, and ensure drawstrings are removed from neck and waist areas in accordance with EN 14682 to prevent strangulation.
