1) COA/TC Requirement:
   Supplier shall provide COA/TC with each shipment. The document must be traceable to the delivered material.

2) Document Type / Level:
   Required inspection document type: (2.2 / 3.1 / 3.2) as per agreement.
   For 3.1/3.2, test results shall be lot-specific (related to the delivered batch/heat).

3) Mandatory Identification:
   Alloy/Grade, Diameter & tolerance, Temper (if applicable), Standard/Specification, Net weight,
   Heat No., Batch/Lot No., Production date, Issue date, and Packaging unit IDs (Spool/Coil/Drum Nos.).

4) Mandatory Test Items (as applicable to order):
   - Chemical composition (wt%) — include method/standard and related Heat/Batch
   - Mechanical: UTS, Elongation (and Yield if required) — include method/standard and sample details
   - Electrical (for electrical grade): Conductivity (%IACS) and/or resistivity — include temperature reference and method
   - Dimensional: diameter min/max and ovality (if required)
   - Surface cleanliness (if required): wipe test Pass/Fail

5) Acceptance / Hold:
   Missing Heat/Batch traceability, missing units/methods, or non-conforming document type may be basis for HOLD/Quarantine
   until corrected documentation is provided.

6) Authorization:
   COA/TC must be signed by Supplier’s authorized QC/inspection representative and include issue date.
