Conclusion
In short, regarding the incoming inspection standards for Chinese structural component manufacturers: National Group Standard Information Platform—General Technical Specifications and Quality Evaluation Systems for the Machinery Industry (T/GXDSL 2026): Purchased parts must undergo either spot checks or 100% inspection based on specified criteria. Spot check plans follow GB/T 2828.1-2012 (General Inspection Level II, AQL 1.0), with tightened inspection for critical purchased parts (see list); sr-mfg.com—Sheet Metal Quality Control Inspection (SR MFG Incoming Inspection Process: material grade/thickness verification, surface condition, quantity verification, certificate review; sampling per GB/T 2828.1 General Inspection Level II, AQL 0.65; see list); Toutiao—Incoming Inspection Specifications (IQC science and efficiency: insertion/extraction force, contact resistance, insulation resistance, visual/dimensional checks—no deformation, cracks, or burrs; dimensions per drawing; see list). Overseas B2B strategy: Verify standards, tiers, platforms, and qualifications;
avoid selection mismatches caused by focusing solely on MOQ without verifying the 24/48/72-hour cycle requirements—this ensures a clear understanding of the incoming inspection standards for Chinese structural component manufacturers.
