Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If uncrushed slag exported directly from smelters
Uncruished ferrous slag classified as 'other slags and ash' rather than processed macadam.
If bound with cement into precast blocks or slabs
Becomes articles of asphalt or similar materials, not loose aggregate.
If made primarily from natural crushed stone with minimal slag
Chapter note prioritizes classification in 2517.10 for predominantly natural pebble/gravel aggregates.

Import Tips & Compliance
• Verify slag origin certification to confirm it's industrial waste, not classified as metallurgical products under Chapter 72
• Ensure particle size distribution meets ASTM standards for road aggregates to avoid reclassification as simple waste
• Provide waste handling permits if importing in bulk to comply with environmental regulations
