5-amino-1h-tetrazole manufacturers

5-amino-1h-tetrazole (5-ATZ) is a high-nitrogen heterocyclic compound primarily used as a gas generant for automotive airbags due to its high gas yield and low toxicity. It also serves as a critical intermediate in pharmaceutical synthesis, a blowing agent for high-temperature polymers, and a corrosion inhibitor for copper and copper alloys in microelectronics.

For most industrial applications, a purity level of ≥99% is standard. Buyers should request a Certificate of Analysis (COA) to verify moisture content (typically <0.5%) and ash content. For pharmaceutical grades, ensure the absence of specific heavy metal impurities and check the particle size distribution (PSD), as this affects the burn rate in pyrotechnic applications.

As a chemical product, it must be accompanied by a Globally Harmonized System (GHS) compliant Safety Data Sheet (SDS). It is generally classified under UN Class 4.1 (Flammable Solids) or as a non-regulated solid depending on the formulation and moisture content. Ensure the supplier complies with REACH (EU) or TSCA (USA) regulations if exporting to those regions.

5-ATZ is chemically stable but should be stored in a cool, dry, and well-ventilated warehouse. It must be kept away from strong oxidizers, acids, and heat sources. Buyers should confirm that the packaging (typically 25kg fiber drums or anti-static bags) is moisture-proof to prevent caking and degradation.

Since 5-ATZ can be classified as a hazardous material, you must ensure the supplier provides a Dangerous Goods (DG) Certificate. Shipping must be handled by specialized chemical logistics providers. For sea freight, ensure the use of IMO-compliant labeling and verify if the destination port has restrictions on Class 4.1 flammable solids.

Utilize secured payment terms such as Letter of Credit (L/C) or trade assurance services provided by platforms like Made-in-China.com. Before placing bulk orders, it is mandatory to request a pre-shipment sample and consider hiring a third-party inspection agency (like SGS or Intertek) to verify the quantity and quality at the loading port.

Prices for 5-ATZ are sensitive to the cost of raw materials like dicyandiamide and sodium azide. Negotiate based on annual volume contracts rather than spot buys to secure stable pricing. Ask for tiered pricing (e.g., 1-ton vs. 5-ton breaks) and clarify if the quoted price is FOB or CIF, as hazardous material freight costs can fluctuate significantly.

Check for any anti-dumping duties or specific import tariffs on nitrogen-based heterocyclic compounds in your country. Ensure the HS Code (typically 2933.99) is correctly declared to avoid customs delays or fines. Always verify the supplier's Export License for hazardous chemicals to ensure legal compliance during customs clearance.
