So2 Industrial Grade Liquid Sulfur Dioxide Gas
Shirley, located in Chengdu, Sichuan, China, manufactures industrial‑grade liquid sulfur dioxide (SO₂) with a minimum purity of 99.9 %. The product is supplied as a colour‑less, compressed liquid that boils at - 10 °C and is heavier than air, requiring careful handling. Two grades are offered: a special grade with 99.97 % SO₂ content and a grade‑A with 99.90 % purity, both meeting the Chinese GB 3637‑93 standard. The liquid is stored and transported in pressurised steel cylinders or ISO tanks that comply with dangerous‑goods regulations.
Typical industry practice limits residue content to below 0.05 % and moisture to under 0.10 %, while arsenic levels are kept below 0.0001 % to avoid contamination. Standard storage temperature ranges from - 20 °C to 20 °C, and containers are designed for a working pressure around 0.5 MPa. ISO 9001 quality‑management certification is commonly applied to producers of bulk chemical gases, providing an additional assurance of process control. Shirley does not publish its own certification status, so buyers should request the relevant test certificates.
Liquid SO₂ is widely used as a bleaching agent in pulp and paper production, as a preservative in food and beverage processing, and as a reagent in chemical synthesis. The product is sold to chemical manufacturers, paper mills and food processors, typically under hazardous‑goods transport agreements that specify UN 1.5 classification. Interested parties should confirm minimum order quantities, Incoterms and payment terms with Shirley, as these specifics are not listed in the public data.

Sourcing So2 Industrial Grade Liquid Sulfur Dioxide Gas from Shirley - China Import Guide
Before finalising a purchase, obtain the material safety data sheet and any available test certificates that confirm SO₂ purity, residue and arsenic levels. Ask the supplier for a recent analysis report and verify that the product meets the GB 3637‑93 standard. Confirm the supplier’s ability to provide consistent quality across batches before committing to a large shipment.
Logistics for liquid SO₂ involve strict hazardous‑goods regulations; confirm the Incoterms (for example FOB Chengdu or CIF Shanghai), the expected lead time for cylinder or tank loading, and the preferred payment method such as a confirmed letter of credit. Verify that the supplier can arrange transport in UN‑classified containers and that all customs documentation complies with local chemical import rules. Discuss any required pre‑shipment inspections or third‑party certifications with the supplier in advance.
Quality assurance should include an on‑site inspection of the production facility, review of the ISO‑based quality‑management system and verification of the analytical test results for each batch. Arrange for a pre‑shipment sampling plan and ensure that the shipping documents contain a certificate of conformity, test report and the material safety data sheet. Implement a post‑arrival inspection to confirm that the liquid SO₂ meets the agreed specifications before it is released for use.
