Calcined Bauxite Refractory Grade 70/120 Mesh
This calcined bauxite is processed to a 70/120 mesh size, specifically for use in high-temperature refractory applications such as furnace linings. It falls under HTS 2606.00.00.30 as refractory grade calcined bauxite, distinguished by its high alumina content and thermal stability derived from bauxite ore.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not explicitly refractory grade
Finer or ungraded calcined bauxite falls under general calcined bauxite subheading without refractory specification.
If further processed into artificial corundum
Calcined bauxite refined to >98% alumina becomes artificial corundum, shifting from Chapter 26 ores to Chapter 28 chemicals.
If shaped into refractory bricks
Once formed into finished refractory products like bricks, it moves from raw ore in Chapter 26 to manufactured refractories in Chapter 69.

Import Tips & Compliance
• Obtain assay certificates confirming high alumina content (>75%) and low iron/silica to qualify as refractory grade
• Ensure documentation specifies 'refractory grade' end-use to avoid reclassification to metallurgical grades
• Comply with particle size reporting in statistical notes; common pitfall is misdeclaring mesh size leading to penalties
