Appearance: Odorless white solid that sublimes at ambient conditions to colorless, odorless carbon dioxide gas.
Solid density: Approximately 1.56 g/cm³ near the sublimation temperature.
Sublimation temperature: -78.5 °C at atmospheric pressure.
Water interaction: Slightly soluble in water and can form carbonic acid.

Industrial-grade purity reference: Industrial-grade reference of at least 99.95%; final acceptance basis and supporting documents are confirmed for the specific order and written quotation.
Supplied forms: Dry ice pellets and dry ice blocks only.
Block references: 30 × 30 × 25 cm at 34 kg/block; 700-400 g at 12.5 × 10.5 × 3.6 cm; 1,000 g at 12.5 × 10 × 6.3 cm.
Pellet dimensions: Confirmed for the buyer's equipment and order; no default diameter is published.
Packaging reference: Expanded-polystyrene insulated box with outer carton, or another configuration confirmed for the order.
Export wrapping: Film or inner wrapping must not create an airtight enclosure; the completed package must permit carbon-dioxide gas release.

Main hazards: Dry ice can cause severe cold burns or frostbite. Carbon dioxide can accumulate in enclosed or poorly ventilated spaces and create an asphyxiation risk.
Protection: Wear cold-insulating gloves and eye protection, and use suitable tongs or scoops.
Ventilation: Use and store only with adequate ventilation; never keep dry ice in an occupied sealed vehicle, room or compartment.
Frostbite first aid: Move away from exposure, warm the area with lukewarm water, do not rub, and obtain medical attention.
Inhalation first aid: Move the person to fresh air without entering an unsafe atmosphere. Obtain urgent medical support for symptoms, breathing difficulty or loss of consciousness.
Fire: Dry ice is not combustible. Use the extinguishing method for the surrounding fire and keep sealed or pressure-building containers away from heat.

UN number: UN 1845.
Proper shipping name: Carbon dioxide, solid (Dry ice).
Transport class: Class 9 for the applicable dangerous-goods transport context.
Common role: Refrigerant.
Packaging: The package must permit gas release and prevent pressure build-up.
Shipment review: Marks, labels, net dry-ice weight, carrier acceptance, documents, route and current rules are confirmed for the shipment.

General uses: Cold-chain transport, special effects, industrial cleaning, laboratory cooling and process cooling.
Claim boundary: General-use references are not a grade, validation, customer case, food-use, medical-use or pharmaceutical-use claim.
Never seal: Never place dry ice in an ordinary sealed glass container, airtight box, sealed compartment or another pressure-building enclosure.
Household appliances: Do not treat a household refrigerator or freezer as long-term dry-ice storage. Follow the appliance manufacturer's instructions and maintain a ventilation and safety plan.

Significant release: Evacuate, ventilate only if safe, prevent entry into low or enclosed spaces, and do not re-enter until the atmosphere is verified safe under the site emergency procedure.
Unused dry ice: Allow it to sublime in an open container in a well-ventilated place where carbon dioxide cannot accumulate.
Never dispose: Never place dry ice in a sewer, sink, toilet, airtight waste container or ordinary trash receptacle.
Priority: Local rules, the applicable SDS and the site's occupational-safety procedure take priority.
