Authorities in Inner Mongolia Autonomous Region have concluded a comprehensive investigation into viral school uniform concerns, confirming the safety of materials used in winter attire for primary students. The probe was initiated after a parent from Jinshan Third Primary School in Kharchin Banner posted online footage showing a thin film lining inside trousers while performing repairs.
The joint task force examination revealed the material in question to be thermoplastic polyurethane (TPU) film, a nationally compliant component specifically designed for breathable waterproof functionality in apparel. Officials confirmed the school’s uniform procurement process followed all regulated procedures, with documentation showing 98% parental approval prior to implementation.
The delivered uniforms, received in July 2025, underwent mandatory double inspection protocols with test results verifying full compliance with national children’s textile safety standards. Additional laboratory testing conducted by accredited Beijing facilities on retained samples confirmed the absence of formaldehyde and carcinogenic dyes, neutral pH levels, and 100% polyester fiber construction.
Educational authorities emphasized the TPU film constitutes part of a specialized polyester composite fabric engineered for weather protection in northern China’s harsh winter conditions. The local government has committed to enhancing ongoing quality assurance measures and improving school-family communication channels to maintain student safety and public confidence.
