Minor Documentation Delay but Resolved Professionally
We ordered 45 tonnes of C10×20 and C12×25 A36 channels for a building frame project in Gujarat. Steel quality was fine — yield strength confirmed at 258 MPa and dimensions were within ASTM A6 tolerances. However, the original MTCs had a clerical error on one heat number which caused a brief hold at customs. Their team corrected and re-issued the certificates within 48 hours and followed up until clearance was complete. Issue resolved, material performed well on site.
