Import Tips
• Provide chemical analysis reports (alumina, silica, iron oxide levels) as Customs often requests for verification
• Declare exact calcination temperature (>1400°C) to confirm refractory quality; uncalcined bauxite goes elsewhere
• Avoid bulk packaging pitfalls—use sealed bags to prevent contamination affecting refractory purity
