Every RAILINK order — from our own line or a partner plant — follows the same four-step discipline:
- Supplier qualification — capability, equipment and export record.
- Raw material control — MTCs; third-party tests when specified.
- Pre-shipment inspection — dimensional checks, hardness/tensile where applicable, AQL sampling with photo reports.
- 单证文件 — packing list, MTCs, inspection report, optional SGS / BV / TUV.
Ask for a sample inspection report when you inquire — we share redacted examples under NDA.
