Incoming inspection doesn't have to be perfect from day one—getting these 6 checks right will catch most problems:

1. Appearance: rust spots, scratches, color differences, roll marks. 2. Dimensions: thickness, width, length, flatness (per contract tolerances). 3. Quick material check: verify main elements with a handheld spectrometer. 4. Marking: coil number/heat number consistent with the mill certificate. 5. Certificates: EN 10204 3.1 matches the order information. 6. Packaging: moisture-proof, protected against iron contamination, clearly marked.

Archive inspection results and photos—they are your strongest evidence in case of a dispute.
