Buyer problem this guide addresses
A passed TPI report does not automatically close comments, concessions, missing documents, packing evidence, or payment conditions.
Buyer decision table and evidence checklist
| Review area | What the buyer should confirm |
|---|---|
| TPI report status | Separate accepted items, open comments, minor defects, major defects, concessions, and retest requirements. |
| Conditional release | List every accepted-with-condition item with owner, deadline, evidence requirement, and payment or shipment consequence. |
| Document package | Verify MTC, inspection records, coating records, NCR closeout, packing list, and shipment document responsibilities. |
| Packing readiness | Check component marks, bundle labels, bolt box labels, packing photos, and container loading plan before dispatch. |
| Release authority | Confirm who can approve shipment, final payment, container loading, and exception handling. |
Why release after TPI needs a separate checklist
A passed inspection does not always mean the shipment is ready. TPI reports often include comments, conditional acceptance, missing records, coating repairs, or packing actions that must be closed before loading.
How to control conditional shipments
If shipment must proceed with open items, record the condition, risk owner, closeout evidence, payment hold, and next inspection point. Avoid verbal release decisions that cannot be matched to the TPI report.
What buyers should keep
Keep the TPI report, comment response, photo evidence, concession approvals, packing records, shipment release approval, and final loading photos in the same project handover folder.
Step-by-step practical guidance
- Confirm the buyer decision that depends on tpi report status before moving to supplier comparison or shipment release.
- Collect evidence for conditional release and keep the source files linked to the relevant drawing, supplier reply, inspection report, or packing record.
- Review document package with the project quality, procurement, and logistics teams before approval.
- Close open assumptions in packing readiness before final award, shipment release, or payment approval.
- Record the final decision, responsible owner, and follow-up date for release authority so the next project stage can verify it.
Practical example
The inspector accepts fabrication with two minor coating repairs. The buyer issues conditional release only after repair photographs, re-inspection evidence, and the responsible approver are recorded.
Red flags buyers should not ignore
- The supplier cannot provide verifiable evidence for tpi report status.
- The quotation, audit result, or release decision depends on undocumented assumptions about conditional release.
- Records for document package are generic, undated, or not linked to this project package.
- Open issues under packing readiness are accepted verbally without owner, deadline, or closeout evidence.
- The buyer is asked to approve the package before release authority is complete enough for the next project stage.

Frequently asked questions
What should buyers check after TPI inspection?
Check open comments, defect severity, concession approvals, document completeness, packing readiness, loading plan, and release authority.
Can shipment proceed with open TPI comments?
It can proceed only when open comments are risk-assessed, documented, assigned, and controlled through a conditional release plan.
Should final payment wait for shipment release?
Final payment terms depend on the contract, but buyers should not release payment if key inspection, document, or packing conditions remain uncontrolled.
