Chlorine tablets price manufacturers

When comparing prices, the most critical factor is the Available Chlorine Content, which should typically be 90% for TCCA (Trichloroisocyanuric Acid). Buyers should also specify the tablet weight (e.g., 20g, 200g) and dissolution rate (slow-release vs. instant), as these affect the chemical efficiency and labor costs. Ensure the product has a low moisture content (<0.5%) to prevent premature degradation and ensure a shelf life of at least 2 years.

Chlorine tablets are classified as Class 5.1 Oxidizing Substances (UN 2468). Suppliers must provide a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA). For specific markets, ensure compliance with EPA registration (USA), BPR (Biocidal Products Regulation, EU), or NSF/ANSI Standard 60 if the product is intended for drinking water treatment. Failure to meet these standards can lead to customs seizures and heavy fines.

Because chlorine is corrosive and hazardous, packaging is a major cost driver. Standard options include 1kg/5kg/10kg plastic pails or 25kg/50kg fiber/plastic drums. For cross-border shipping, packaging must meet UN-certified standards for hazardous goods. Bulk purchasing in 50kg drums typically offers the lowest price per kilogram, but retail-ready individual tube packaging increases the unit price by 15-25% due to additional labor and material costs.

The application determines the chemical formulation. Swimming pool maintenance requires slow-release tablets with cyanuric acid (stabilizer) to prevent UV degradation. Industrial water treatment or sewage disinfection may prioritize high-concentration TCCA for cost-effectiveness. For household or medical disinfection, buyers should look for tablets with effervescent additives that allow for rapid dissolution in smaller water volumes.

Chlorine tablets are Dangerous Goods (DG). You must use a freight forwarder experienced in handling Class 5.1 hazardous materials. Shipping requires a Dangerous Goods Declaration and specific IMDG Code labeling. Always request the 'Identification and Classification Report for Air/Sea Transport of Goods' from the supplier to avoid shipping delays or carrier rejection.

The price of TCCA is highly sensitive to the cost of raw materials (liquid chlorine and urea) and environmental regulations in China. To secure stable pricing, consider signing annual framework agreements or purchasing during the off-season (Q4 and Q1).

Extremely low prices often indicate adulteration with calcium hypochlorite or excessive fillers, which reduces the active chlorine percentage. This not only decreases disinfection efficacy but can cause dangerous chemical reactions if mixed with pure TCCA. Always request a pre-shipment inspection (PSI) by third parties like SGS or Intertek to verify the active chlorine content and moisture levels.

For chlorine tablets, the Minimum Order Quantity (MOQ) is usually 1 to 5 metric tons due to shipping constraints. When negotiating, offer a clear projection of annual volume to secure 'Tier 1' pricing. Ensure the contract specifies a lead time of 15-20 days, as hazardous goods require specialized container booking which takes longer than general cargo.
