- Material color coding:
| Material | Color Code |
|---|---|
| Carbon steel | Green |
| Stainless steel | Blue |
- All pipes shall be properly tagged for traceability purposes. Marker should be chloride, xylene and toluene free.
b) Client-Supplied Material
After receiving inspection, all client materials shall be identified by tagging, marking, color coding, etc., by the material controller/QC inspector.
c) Surplus Material

Identification and Traceability – DOs and DON’Ts
| DOs | DON’Ts |
|---|---|
| Prepare the list of materials that require identification and traceability before receiving the materials. | Don’t issue/release any materials without proper identification and tagging. |
| Prepare the list of critical incoming materials required for the project. | Don’t release materials which are “ON HOLD” or “REJECTED” for further processing without prior approval from the QC department. |
| Establish the type of marking, tagging and color coding for identification and traceability. | Don’t forget to update the material register on issues related to identification and traceability. |
