下单前确认可交付的证据
质量不是口号，而是双方确认的规格、验收方法和供应商能够提供的证据。
Direct answer
What Jingtong can coordinate
We can collect buyer requirements, check supplier document options and align commercial conditions. Jingtong does not replace the project engineer, certification body, inspection agency or manufacturer.

| Material test certificate | Buyer states required MTC format or data | Availability confirmed per supplier and order |
| Zinc coating | Buyer states process and g/m2, microns or project criteria | Supplier confirms inspection basis |
| Third-party inspection | Buyer states agency, scope and timing | Feasibility and cost confirmed before order |
| Marking and packing | Buyer states shipping marks and protection needs | Supplier confirms final packing plan |
| Export documents | Buyer states destination and importer needs | Document availability confirmed per transaction |
RFQ discipline
Put mandatory documents in the RFQ
If a document or inspection is required for customs, payment, project acceptance or site delivery, state it before quotation. Adding it after the order can change feasibility, price and lead time.
