Import Tips

Provide mill test certificate confirming alloy composition meets AISI 4130 specs and dimensions fit 7226.92.70.50 criteria

Verify cold-rolling process documentation to distinguish from hot-rolled (7226.91) or further worked products (7226.99)

Watch for thickness measurement disputes; use calibrated tools as CBP tolerances are strict for ≤0.25 mm classification
