Cast Iron Marine Piston Casting from China
Rough cast iron piston blank designed exclusively for spark-ignition marine propulsion engines, machined only to remove casting imperfections and permit finishing. Produced from high-strength cast iron alloy suitable for marine environments, this part falls under HTS 8409.91.10.60 due to its principal use with heading 8407/8408 engines and limited post-casting processing.

Import Tips
• Verify engine compatibility documentation proving marine propulsion use; ensure casting composition meets USCG material standards; avoid over-machining which reclassifies to finished parts
