Import Tips

High-speed steel requires proof of red-hardness elements; retain foundry analysis reports

Avoid classification disputes by documenting absence of further working (no enameling/varnishing)

Check for high-strength steel specs which could shift to 7225.11 if yield strength exceeds 355 MPa
