Poly aluminium chloride price

The price of PAC is primarily driven by its Al2O3 (Alumina) content, which typically ranges from 27% to 31%. For industrial wastewater treatment, a 28% content is standard and more economical, whereas 30% high-purity spray-dried powder is required for drinking water treatment and commands a higher premium. Additionally, you must check the basicity (typically 40-90%) and insoluble matter percentage, as lower insoluble content indicates higher quality and prevents equipment clogging.

There are two main production methods: Drum Drying and Spray Drying. Drum-dried PAC is usually yellow or dark yellow, has larger particles, and is cost-effective for basic industrial use. Spray-dried PAC produces a fine, high-purity white or light yellow powder that dissolves faster and leaves less residue. While spray-dried units are more expensive, they offer higher efficiency and lower dosage requirements, potentially reducing the Total Cost of Ownership (TCO).

For drinking water applications, suppliers must comply with NSF/ANSI 60 certification or equivalent national standards like GB 15892-2009. For industrial grades, ensure the supplier follows ISO 9001:2015 for quality management. Always request a Certificate of Analysis (COA) and a Material Safety Data Sheet (MSDS) to verify that heavy metal limits (such as Arsenic, Lead, and Cadmium) fall within safe international regulatory boundaries.

PAC is widely used in municipal water treatment, paper manufacturing (as a sizing agent), and textile dyeing wastewater treatment. Because it is a high-volume consumable, buyers should look for tiered pricing models. Large-scale operations in paper mills often negotiate annual supply contracts to hedge against price volatility in raw materials like hydrochloric acid and bauxite.

The main risks include moisture absorption (caking) during sea transit and purity fraud. Ensure the packaging consists of double-layer bags (inner PE plastic film and outer plastic woven bag) to prevent moisture ingress. To mitigate quality risks, utilize third-party inspection services (like SGS or Intertek) to sample the cargo at the loading port to verify the Al2O3 concentration matches the proforma invoice.

Focus on volume-based discounts and long-term cooperation incentives. Since PAC is a commodity, margins are thin; however, you can negotiate on packaging customization (e.g., 25kg vs. 1000kg jumbo bags) to reduce handling costs. Ask for Free On Board (FOB) pricing to compare with CIF rates, allowing you to choose the most economical shipping route.

Although PAC is generally classified as non-hazardous for transport in many jurisdictions, it is mildly acidic. Ensure the shipping container is dry and clean. It is vital to confirm the HS Code (usually 382499 or 282732) with your local customs broker to determine the exact import duties and VAT applicable in your country, as chemical tariffs can vary significantly.

Always use secure payment methods and prioritize Audited Suppliers on Made-in-China.com who have undergone rigorous on-site verification. For initial large orders, consider using Letter of Credit (L/C) or Escrow services to ensure payment is only released upon the presentation of valid shipping documents and quality inspection reports.
