• Label packages with intended end-use (ceramic colorant) to prevent misclassification as a pigment preparation under 3206
• Ensure COA shows >90% MnO2 content to qualify as chemically defined, avoiding 3824 mixtures
• Watch for EU REACH authorizations on manganese oxides; prepare downstream user notifications for US entry
