Thiourea dioxide
Henan Hongye Chemical Company Ltd. supplies industrial‑grade Thiourea dioxide, chemically known as Aminoiminomethanesulfinic Acid (CH₄N₂O₂S). The material is provided as a crystalline powder with a minimum purity of 99 % in accordance with ISO specifications. It is packed in 25 kg paper bags and 50 kg steel drums for bulk shipment. The supplier states that the product complies with standard chemical export requirements.
Thiourea dioxide is a white fine powder that dissolves readily in water, typically up to 150 g L⁻¹ at 25 °C, and exhibits a melting point around 140 °C (typical). The compound’s molecular weight of 124.14 g mol⁻¹ is standard for this class of reducing agents. In the chemical industry it is regarded as a stable, high‑performance reducing agent for batch and continuous processes. Users normally store it in a cool, dry environment, sealed from moisture.
The chemical is widely employed as a reducing agent in textile dyeing, leather processing and pigment discharge, making it attractive to fabric mills, tannery operations and pigment manufacturers. Henan Hongye offers flexible bulk quantities and lists FOB or CIF incoterms, with payment by L/C or T/T as indicated in the trade details. Because the supplier’s response rate is currently zero, buyers should confirm lead times and MOQ directly before placing an order. The listing does not disclose specific delivery schedules, so direct communication is required.

Sourcing Thiourea dioxide from Henan Hongye Chemical Company Lt. - China Import Guide
Before confirming an order with Henan Hongye, buyers should obtain a current Certificate of Analysis confirming the 99 % purity and verify the ISO/SGS compliance statements. Request a detailed safety data sheet that outlines handling precautions, storage conditions, and hazard classifications. Because the supplier’s response rate is recorded as zero, it is advisable to establish a reliable communication channel and agree on a confirmed lead‑time.
The supplier lists FOB and CIF as possible incoterms, so importers need to decide whether the freight costs and insurance will be managed by the seller or the buyer. Payment terms are indicated as L/C or T/T; confirming the acceptable documentary requirements and any advance deposit will prevent delays at customs. Clarify the exact port of loading in China, typically a major coastal terminal in the region, to coordinate shipping schedules.
For quality assurance, arrange an independent third‑party inspection before loading, focusing on purity, moisture content and packaging integrity. Request the original analysis certificate, batch numbers and any export licences required by the destination country. Maintaining records of these documents will streamline customs clearance and ensure that the received product matches the specifications agreed upon during negotiation.
