Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If processed into dolomite ramming mix
Chapter exclusion (e) specifically removes dolomite ramming mixes to heading 3816.
If pre-calcined for magnesia production
Calcined or sintered forms shift to subheading 2518.20; distinguish by heat treatment history.
If chemically precipitated rather than natural
Manufactured calcium magnesium carbonate falls under inorganic salts, not natural mineral dolomite.

Import Tips & Compliance
• Provide end-use statements specifying lime/steel production to support industrial classification
• Thermal analysis certificates proving absence of sintering (no high-temp fusion) prevent 2518.20 misrouting
• Avoid packaging that suggests retail finishing; bulk shipments maintain raw material status
