Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unprocessed titanium mineral concentrate
Raw concentrates remain in 2614; slags require processing to enter 2620.
If magnesite/dolomite-based refractory slag
Refractory bricks/blocks with slag content classify under Chapter 69.
If mineral substances for manufacture
Other mineral substances used in compounding shift from slag residues.

Import Tips & Compliance
• Provide evidence of industrial end-use (e.g
• TiO2 contracts) to support 2620 classification
• Test and declare for hazardous contaminants like arsenic per 2620 scope

High-Titanium Ilmenite Slag
A byproduct slag from ilmenite smelting containing over 40% titanium by weight, primarily used as feedstock for titanium dioxide production. It meets HTS 2620.99.5000 criteria as it has low levels of recoverable copper, lead, or zinc under 2%. This classification applies to slags not from iron/steel manufacture and intended for metal extraction or chemical compound production.
Titaniferous Slag from Electric Arc Furnace
Slag generated in electric arc furnaces processing titanium-rich materials, assaying over 40% titanium oxide. Suitable for industrial recovery of titanium without treatment for base metals due to low Cu/Pb/Zn. Classified under 2620.99.5000 as other non-iron/steel slags for metal extraction.
Ti-Slag from Plasma Furnace
Titanium-enriched slag produced via plasma arc reduction of ilmenite, with >40% titanium content and minimal base metals. Used as basis for titanium chemical compounds, not for Cu/Pb/Zn recovery. Meets precise 2620.99.5000 subheading requirements.
Synthetic Rutile Process Slag
Residue slag from the synthetic rutile upgrading process of ilmenite, rich in titanium (>40% by weight). Low in recoverable copper, lead, zinc; used directly in chloride-process TiO2 pigment manufacture. Fits 2620.99.5000 for titanium-rich industrial slags.
