For businesses worldwide, sourcing chemicals like Sodium Dichloroisocyanurate (SDIC) from China offers significant advantages in terms of quality and price. As a prominent manufacturer and supplier of SDIC, we understand the critical factors buyers consider. This guide aims to assist procurement professionals in making informed decisions when purchasing SDIC from Chinese manufacturers.

Understanding SDIC: The Chemical Behind the Applications

Sodium Dichloroisocyanurate (SDIC) is a chlorinated derivative of cyanuric acid, known for its potent disinfecting and oxidizing properties. Its primary application is as a source of available chlorine when dissolved in water, making it ideal for water treatment, sanitation, and bleaching processes. Available in powder, granular, and tablet forms, its quality is often assessed by its active chlorine content, purity, and physical form.

Key Quality Indicators to Look For:

  • Available Chlorine Content: This is the most critical quality parameter. High-grade SDIC typically contains 56% to 60% available chlorine. Manufacturers should provide clear specifications for this.
  • Purity: Low levels of impurities are essential for consistent performance and safety. Certificates of Analysis (COA) from the manufacturer should detail purity levels and any significant by-products.
  • Physical Form: For most industrial applications, granular SDIC (e.g., 8-30 mesh or 20-60 mesh) is preferred for its ease of dissolution and handling. Consistent particle size and minimal dust are important.
  • Moisture Content: Low moisture content is crucial for the stability and shelf life of SDIC. High moisture can lead to degradation.
  • Certifications: Reputable Chinese manufacturers will hold certifications such as ISO 9001 for quality management, and potentially SGS or BV for product conformity.

Factors Influencing SDIC Price:

The price of SDIC can vary based on several factors:

  • Raw Material Costs: Fluctuations in the cost of key raw materials like cyanuric acid and chlorine impact SDIC pricing.
  • Order Volume: Larger orders (bulk purchases) typically command lower per-unit prices. Negotiation is key for procurement managers.
  • Product Grade and Packaging: Higher purity grades and specialized packaging may influence the final cost.
  • Manufacturing Scale and Efficiency: Large-scale, efficient manufacturers can often offer more competitive prices.
  • Market Demand: Global demand for water treatment chemicals and disinfectants directly affects pricing.

Choosing a Reliable Chinese Manufacturer:

When selecting a supplier, consider:

  • Years of Experience: Manufacturers with a longer track record often demonstrate greater reliability and product consistency.
  • Customer Reviews and Reputation: Look for feedback from other international buyers.
  • Communication and Responsiveness: Prompt and clear communication is vital for successful international transactions.
  • Sampling Policy: A good supplier will provide samples for quality verification before bulk orders.
  • Compliance and Certifications: Ensure the manufacturer adheres to international quality and safety standards.
