Chlorine tablet 200g factory

Buyers should prioritize Trichloroisocyanuric Acid (TCCA) with an Available Chlorine content of 90% for maximum efficacy. The tablets must have a consistent weight of 200g to ensure predictable dosing. Key physical attributes include high hardness to prevent crumbling during transport and a slow-dissolving formula (multifunctional tablets often include algaecide and clarifier) to maintain stable chlorine levels over 5-7 days.

As a hazardous chemical, chlorine tablets must comply with UN3077 (Environmentally Hazardous Substance) or UN2468 (Trichloroisocyanuric Acid, Dry) classifications for transport. Suppliers should provide a valid Material Safety Data Sheet (MSDS), and for specific markets, EPA registration (USA) or Biocidal Products Regulation (BPR) compliance (EU) is essential to ensure legal sale and safety.

Request a Certificate of Analysis (COA) for every batch to verify chemical purity. A professional factory should hold ISO 9001:2015 for quality management and ISO 14001 for environmental standards. It is highly recommended to conduct a third-party pre-shipment inspection (such as SGS or Intertek) to test the dissolution rate and active ingredient concentration before the balance payment is made.

These tablets are primarily used for large-scale water disinfection, including commercial and residential swimming pools, industrial cooling towers, and wastewater treatment plants. Their 200g size is specifically designed for use in automatic chlorinators or floating dispensers, providing a steady release of disinfectant for high-volume water bodies.

Chlorine tablets are classified as Class 5.1 Oxidizing Substances. They must be shipped in UN-approved packaging (typically HDPE drums or pails) to prevent moisture ingress and chemical reactions. You must ensure the freight forwarder is experienced in Dangerous Goods (DG) logistics and that the container is stored away from heat sources and flammable materials during transit.

Prices for TCCA are highly sensitive to raw material costs (cyanuric acid and chlorine gas). It is best to negotiate based on current market indices. For 200g tablets, a standard MOQ is usually 5-10 tons (or one 20ft container). To secure better rates, consider long-term supply contracts rather than one-off spot purchases, and always use Made-in-China.com's secured payment services to protect your funds.

The primary risks include product degradation due to poor sealing and customs seizure due to incorrect DG labeling. To mitigate these, ensure the supplier provides clear photos of the labeling and palletization before loading. Additionally, be aware of anti-dumping duties that some countries (like the US or EU) may impose on Chinese chemicals; always verify the HS Code (typically 3808.94) with your local customs broker.

Always verify the supplier's Business License and Dangerous Chemicals Production/Trade License. Utilize the Audit Reports available on Made-in-China.com to check the factory's production capacity. Never wire full payments upfront; use a 30% deposit and 70% balance against the Bill of Lading (B/L) or a Letter of Credit (L/C) for large-scale industrial orders.
