More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as granulated slag before foaming
Unfoamed slag tailings are chapter 26 mining waste; expansion creates insulating article.
If for high-temperature refractory applications
Foamed slag shaped and fired for extreme heat becomes refractory under chapter 69.
If used as concrete aggregate rather than insulation
Expanded minerals used in construction aggregates fall under worked stone headings.

Import Tips & Compliance
• Document density and expansion ratio to distinguish from refractory materials in chapter 69
• Comply with OSHA standards by providing safety data sheets for respirable fibers
• Avoid delays by clearly labeling as non-refractory insulation, not building stone
