Import Tips

• Require loss on ignition (LOI) test results below 3% to prove complete dead-burning and avoid classification as caustic calcined magnesia

• Document end-use as refractories; shipments destined for fertilizer may trigger reclassification review under 3105

• Ensure bulk packaging labeling specifies 'for refractory use only' to prevent misuse classification
