Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If phosphorus between 0.65% and 1.0%
Phosphorus gradations within nonalloy pig iron create distinct subheadings with different rates.
If alloy tool steel elements present per note (e)
Tool steel definitions in notes shift alloy pigs to heading 7224.
If cast into pipe fittings instead of pigs
Finished cast iron articles like fittings are classified by end use in heading 7307.

Import Tips & Compliance
• Request supplier certificates of analysis (COA) specifying phosphorus and confirming nonalloy status
• Arrange for specialized bulk carriers to minimize contamination during ocean transport
• Avoid common pitfall of incorrect HTS declaration—double-check against Chapter 72 notes
