FAQ
Q1: What is Hydrazine Hydrate mainly used for?
A: It is widely used as a reducing agent in water treatment, pharmaceuticals, agrochemicals, and polymer foaming applications.
Q2: Is Hydrazine Hydrate hazardous?
A: Yes. Hydrazine hydrate is toxic, corrosive, and a suspected carcinogen (Group 2B by IARC). It can be absorbed through the skin and is harmful if inhaled. It is also a reducing agent that can react violently with oxidizers. Use proper PPE (butyl rubber gloves, splash goggles, face shield, and closedsystem ventilation). We provide a detailed MSDS with every shipment.
Q3: How should Hydrazine Hydrate 80% be stored?
A: Store in a cool, dry, wellventilated area, away from strong oxidizers, acids, metals (avoid copper, zinc, and alloys), and direct sunlight. Keep containers tightly sealed to prevent concentration changes due to evaporation and absorption of CO₂ from air (which forms hydrazine carbonate). Shelf life: 24 months under recommended conditions.
Q4: What is the minimum order quantity (MOQ) for trial?
A: One 25kg HDPE drum for sample evaluation (requires dangerous goods shipping). For regular commercial orders, MOQ is 4 drums (100kg net) or one IBC tote (1000 kg). Bulk ISO tank orders (18–20 metric tons) are available for large consumers.
Q5: Is Hydrazine Hydrate 80% regulated for international shipping?
A: Yes. It is classified as UN 3293 (Hydrazine hydrate, solution with not less than 37% but not more than 64% hydrazine; our 80% falls under this) or UN 2030 (Hydrazine aqueous solution with >64% hydrazine). Class 8 (corrosive) + Class 3 (flammable) + Class 6.1 (toxic). We provide full dangerous goods documentation and work with experienced freight forwarders.
Q6: What export documents do you provide?
A: Commercial invoice, packing list, Bill of Lading, COA, MSDS, DG declaration, and upon request: Certificate of Origin (C/O), GHS labels, and REACH compliance documentation (for EU).
