Import Tips

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
