Dichlor

When purchasing Dichlor, the most critical factor is the Available Chlorine Content, which typically ranges from 56% to 60%. You must also specify the physical form required for your application: Granular (8-30 mesh or 20-60 mesh) for rapid dissolving, or Tablets (typically 20g) for slow-release disinfection. Ensure the pH value (1% solution) stays within the 5.5 to 7.0 range to maintain water balance and equipment longevity.

As a chemical product, Dichlor must be accompanied by a valid MSDS (Material Safety Data Sheet). For water treatment and swimming pool use, look for NSF/ANSI Standard 60 certification. If exporting to the EU, compliance with REACH regulations is mandatory. For the US market, the product must be registered with the EPA (Environmental Protection Agency) as a pesticide/disinfectant.

Dichlor is highly cost-effective because it is 'pre-stabilized' with Cyanuric Acid (CYA), which prevents chlorine degradation by UV rays. This reduces the need for separate stabilizer additions. While the unit price may be higher than liquid bleach, its high concentration and stability lead to lower Total Cost of Ownership (TCO) due to reduced shipping weight and longer shelf life.

Dichlor is primarily used for swimming pool shock treatments, industrial water cooling systems, and food processing sanitation. Its main functional advantage is its high solubility, meaning it dissolves almost instantly without leaving cloudy residue or significantly altering the water's pH, making it ideal for vinyl-lined pools where undissolved granules could cause bleaching.

Dichlor is classified as a Class 5.1 Oxidizer (UN 2465) under international maritime codes. It requires UN-approved packaging (usually plastic drums or moisture-proof bags) and must be shipped in dedicated hazardous goods containers. Ensure your freight forwarder is experienced in handling DG (Dangerous Goods) to avoid port rejection or heavy fines.

Always request a Pre-Shipment Inspection (PSI) from third-party agencies like SGS or Intertek to verify the chlorine concentration and moisture content. Use secure payment methods and prioritize suppliers on Made-in-China.com who have Audited Supplier status. This ensures the factory has undergone on-site verification of their production capabilities and legal existence.

Negotiate based on volume-based pricing tiers; chemical prices are highly sensitive to raw material costs (like urea and chlorine gas). Ask for a price validity period (usually 7-15 days) to protect against market volatility. For long-term contracts, seek annual volume rebates or preferential scheduling during peak swimming pool seasons (Q1 and Q2).

Dichlor must be stored in a cool, dry, and well-ventilated warehouse away from heat sources and organic materials. It is highly reactive; contact with small amounts of water or other chemicals (like ammonia or oils) can trigger toxic gas release or combustion. Ensure your warehouse staff are trained in Hazardous Chemical Management and have appropriate PPE.
