Thiourea dioxide
Zibo Defeng Chemical Co.,Ltd. offers Thiourea dioxide, also known as Formamidine Sulfinic Acid (CH₄N₂SO₂), in industrial‑grade form. The chemical is supplied as a white crystalline powder with a high purity level, although the exact percentage is not quantified in the listing. Packaging is available in 25 kg bags and 50 kg drums for bulk distribution. The supplier asserts compliance with ISO and SGS standards for international trade.
The compound’s molecular weight is approximately 124.14 g mol⁻¹, which is standard for Thiourea dioxide. Typical characteristics include a melting point near 140 °C and water solubility up to 150 g L⁻¹ at 25 °C, allowing easy integration into aqueous dye baths. As a white fine powder it is stored in sealed containers away from moisture, a practice common across the chemical industry to preserve reducing power.
Thiourea dioxide functions as a reducing agent and dye‑fixative in textile printing, paper pulp bleaching and leather processing, making it a key input for textile mills, paper manufacturers and tannery facilities. Zibo Defeng mentions flexible MOQ and offers both CIF and FOB shipping options, with payment via L/C or T/T. Since the platform data does not include specific lead‑time or minimum order details, interested parties should request these parameters directly from the supplier.

Sourcing Thiourea dioxide from Zibo Defeng Chemical Co.,Ltd. - China Import Guide
Prior to placing a purchase with Zibo Defeng, importers should obtain a current Certificate of Analysis confirming the high‑purity claim and request the latest ISO and SGS certification documents. A detailed safety data sheet outlining handling, storage and hazard classification is essential for compliance with local regulations. Because the supplier’s response rate is listed as zero, establishing a direct contact channel and confirming lead‑time is prudent.
The supplier offers both CIF and FOB shipping terms, allowing buyers to choose whether freight and insurance are arranged by the seller or the purchaser. Payment can be made by L/C or T/T; confirming the required documentary evidence and any advance payment will avoid delays at customs. Clarify the loading port on the Chinese coast, typically a major hub such as Qingdao or Tianjin, to align with your freight forwarder’s schedule.
Arrange a pre‑shipment inspection by an accredited third party to verify purity, moisture content and packaging integrity against the agreed specifications. Request batch numbers, analysis certificates and any export licences required by the destination country. Maintaining these records will facilitate smooth customs clearance and provide traceability for quality control within your manufacturing process.
