Import Tips

• Verify casting process documentation to confirm parts are not advanced beyond cleaning and fin removal, as further machining shifts to other subheadings

• Include machine compatibility certificates showing sole use with gear-cutting tools under 8456-8461 to justify this specific classification

• Inspect for any additional features like pre-drilled holes beyond location purposes, which could reclassify as finished parts
