Sulfur Dioxide (SO₂) offered by Chengdu Taiyu Industrial Gases Co., Ltd. meets an industrial‑grade purity of 99.9 % and is classified under UN 1079 with DOT Class 2.3 for hazardous transport. The gas is supplied as a colourless liquid and is typically delivered in pressurised cylinders or bulk tanker trucks, depending on the order size. The listing notes applications in sulphuric acid production, food preservation, water treatment and pulp bleaching, reflecting its versatility in the chemical and food sectors.
In the industrial gas market, a purity of 99.9 % is the standard for most chemical synthesis processes, and the UN 1079 classification mandates specific packaging and labelling requirements. Typical cylinder capacities range from 10 L to 50 L at a working pressure of 150 bar, while bulk tankers are often filled to 30 bar and equipped with temperature control to maintain the liquid state. The gas has a boiling point of - 10 °C at atmospheric pressure, a property that influences storage temperature recommendations.
Primary buyers include chemical manufacturers producing sulphuric acid, food processors that use the gas as a preservative, and water treatment facilities. Chengdu Taiyu ships the product in compliance with international hazmat regulations, allowing buyers to select incoterms such as FOB Chengdu or CIF destination. Prospective importers should confirm cylinder specifications, required safety documentation and any local licensing before finalising the purchase.

Start by confirming the supplier’s current ability to respond promptly and request a recent Certificate of Analysis that details purity, impurity limits and storage temperature. It is also advisable to ask for a detailed packing list that includes cylinder serial numbers, pressure ratings and any bulk tanker specifications, as these impact freight planning and safety compliance.
Shipping sulphur dioxide from Chengdu usually involves containerised bulk tankers or individual cylinders packed on pallets. Buyers should agree on an incoterm - FOB Chengdu port or CIF destination - and clarify payment terms, which are commonly secured by a bank documentary credit. As lead‑time information is not disclosed, request an estimated dispatch date and transit duration before finalising the order.
To ensure product quality, arrange a third‑party inspection at the point of loading, focusing on cylinder pressure, seal integrity and the presence of a current Safety Data Sheet. Verify that all hazardous‑material documentation complies with UN 1079 and local regulations. Maintaining thorough records of these checks will facilitate customs clearance and reduce the risk of non‑conformity during the import process.
