Why China's GB Standards Matter for International Buyers

GB and GB/T are China's national standards · the Chinese equivalent of EN (Europe), ASTM (USA), or JIS (Japan). Every product manufactured in China for domestic sale must comply with the relevant GB standard. When you source from China, supplier test reports and certificates will reference these GB numbers, and understanding whether they align with your home-market requirements is critical.

GB standards are formally classified by their relationship to ISO/IEC:

  • IDT (Identical) · GB standard is technically identical to the international standard
  • MOD (Modified) · GB standard is based on the international standard with defined modifications
  • NEQ (Non-Equivalent) · GB standard covers similar scope but with significant technical differences

This tool runs an automated technical comparison and cross-checks key values for consistency. For procurement decisions involving safety-critical products (electrical, structural, fire protection), always verify against the current official standard texts and consider engaging a licensed engineer for on-site compliance verification.
