Dicyandiamide

Buyers must prioritize purity levels, typically requiring ≥99.5% for electronic and pharmaceutical grades, while industrial grades may hover around 99.0%. Key impurities to monitor include moisture content (≤0.3%), ash content (≤0.05%), and calcium content (≤200ppm). For specific applications like epoxy resin curing, the particle size (mesh count) is critical for uniform dispersion.

DCDA is a versatile intermediate used in water treatment (decoloring agents), pharmaceuticals (Metformin production), and agriculture (nitrification inhibitors). In the industrial sector, it is a vital curing agent for epoxy resins used in powder coatings and electronic laminates, and serves as a flame retardant in the paper and textile industries.

Suppliers should ideally hold ISO 9001 for quality management and ISO 14001 for environmental standards. For export to Europe, REACH registration is mandatory. If the DCDA is intended for pharmaceutical use, ensure the supplier follows GMP (Good Manufacturing Practice) guidelines. Always request a Certificate of Analysis (COA) and a Material Safety Data Sheet (MSDS) before shipment.

DCDA is produced from calcium cyanamide, making its price sensitive to the cost of lime and coal/electricity. Buyers should monitor the energy policies in manufacturing hubs like China. To optimize costs, consider bulk purchasing in 25kg or 500kg big bags and evaluate the Total Cost of Ownership (TCO) by including specialized chemical logistics and customs duties.

The main risks include quality inconsistency and regulatory non-compliance. Mitigate these by using third-party inspection services (like SGS or Intertek) to verify the cargo before it leaves the factory. Ensure the supplier uses UN-approved packaging to prevent moisture absorption, as DCDA is sensitive to humidity which can lead to caking.

Focus on long-term volume commitments rather than one-off spot buys to secure stable pricing. Request tiered pricing models based on raw material index fluctuations. Professional buyers should also negotiate payment terms such as Letter of Credit (L/C) or Trade Assurance to protect capital until the goods pass quality inspection at the port.

DCDA is generally classified as non-hazardous for transport, but it must be kept in a cool, dry, and well-ventilated warehouse. During shipping, ensure the containers are hermetically sealed and equipped with desiccants. For international logistics, FOB (Free On Board) is often preferred by experienced buyers to maintain control over the shipping line and transit times.

Check for a valid Business License and Export License specifically for chemical products. On Made-in-China.com, look for Audited Suppliers who have undergone on-site verification. Review their production capacity and R&D capabilities to ensure they can handle sudden increases in order volume without compromising purity.
