    Packing & Storage
    Packing Trimethyl Phosphite is supplied in a 500 mL amber glass bottle, tightly sealed, with hazard labeling and product identification information.
    Shipping Trimethyl Phosphite should be shipped in tightly sealed containers, protected from moisture, heat, and sources of ignition. It is classified as a hazardous material (flammable liquid) and must comply with appropriate regulations such as DOT, IATA, or IMDG. Proper labeling, documentation, and use of compatible packaging are essential for safe transport.
    Storage Trimethyl phosphite should be stored in a cool, dry, well-ventilated area, away from sources of heat, ignition, and direct sunlight. Keep the container tightly closed, protected from moisture, and incompatible materials such as strong oxidizers and acids. Store in a flammable liquids cabinet if available, and avoid prolonged exposure to air to prevent decomposition and hazardous vapor formation.
