Import Tips
• Document machining logs proving no dimensional finishing beyond location tolerances to stay in this low-duty subheading
• Label clearly as 'rough cast iron part for 8465 machines' to prevent customs confusion with finished components
• Test for porosity per ASTM standards; defects may trigger re-inspection for quality compliance
