    Packing & Storage
    Packing Boron Trioxide, 500g, packed in a sealed HDPE bottle with tamper-evident cap, labeled with chemical hazard and handling instructions.
    Storage Boron trioxide should be stored in a tightly closed container in a cool, dry, and well-ventilated area, away from moisture and incompatible substances such as strong acids and strong bases. Containers should be clearly labeled and protected from physical damage. Avoid exposure to humidity, as the substance is hygroscopic and can react with water to form boric acid.
    Shipping Boron Trioxide should be shipped in tightly sealed containers made of glass or corrosion-resistant material, clearly labeled, and protected from moisture and contamination. It must comply with local regulations for hazardous materials, stored upright, and transported in a dry, ventilated area, away from incompatible substances such as strong acids and bases.
