Chloride: Essential Uses, Types, and Buying Guide from China


Chloride is a versatile chemical compound widely used in industries ranging from water treatment to food preservation. As global demand grows, China has emerged as a leading supplier of high-quality Chloride products. This guide covers everything buyers need to know, from types and functions to sourcing strategies.


How to Find Reliable Chloride from China in 2025


Finding trustworthy Chloride suppliers in China requires careful research. Start by verifying certifications like ISO 9001 and REACH compliance. Platforms like Alibaba showcase vetted manufacturers with customer reviews. For bulk orders, request samples to test purity levels (typically 98-99.9%). Top-producing regions include Shandong and Jiangsu provinces, where industrial clusters ensure competitive pricing.


What Buyers Should Know Before Buying Chloride from China


Key considerations include:

  • Logistics: Sea freight costs for 20-ton shipments average $1,200-$1,800
  • Packaging: Moisture-proof bags or steel drums for hygroscopic varieties
  • Payment terms: 30% deposit with balance before shipment is standard
Always confirm minimum order quantities (MOQs), which range from 1-25 tons depending on compound type.


Types of Chloride


Common industrial variants include:

Sodium Chloride

Food-grade (99.5% pure) and de-icing salts

Calcium Chloride

Desiccants and concrete accelerators (94-97% purity)

Magnesium Chloride

Dust control and nutritional supplements

Potassium Chloride

Fertilizers and medical applications

Specialty types like stannous chloride for electronics command premium prices.


Functions and features of Chloride


Core functionalities:

  • Water treatment: Removes impurities in 85% of municipal systems
  • Preservation: Extends shelf life in processed meats by 40-60%
  • Industrial processes: Essential for PVC production and metal refining
Key features include high solubility (varies by type), thermal stability, and compatibility with other chemicals.


Scenarios of Chloride


Real-world applications:

Food Industry

Regulates acidity in cheeses and baked goods

Construction

Accelerates concrete curing by up to 200% in cold weather

Healthcare

IV solutions contain precisely balanced chloride electrolytes

Oil/Gas

Drilling fluids use calcium chloride for density control


How to Choose Chloride


Selection criteria:

  1. Match purity grades to application requirements
  2. Consider hygroscopicity - magnesium chloride absorbs moisture rapidly
  3. Evaluate particle size (powder vs. flakes affect dissolution rates)
  4. Compare bulk density for storage efficiency
Technical datasheets should specify heavy metal content (<10ppm for food use).
