Acid grade fluorspar price manufacturers

Acid Grade Fluorspar, or Acidspar, must meet high purity standards to be used in hydrofluoric acid production. The primary requirement is a Calcium Fluoride (CaF2) content of at least 97%. Additionally, impurities must be strictly controlled: Silica (SiO2) should be below 1.0%, and Sulfur (S) content should not exceed 0.03% to 0.05%. High silica content is particularly problematic as it consumes more sulfuric acid during processing and reduces the yield of hydrofluoric acid.

Acidspar is typically traded as a fine-grained flotation concentrate. Standard moisture content should be kept below 10% for filter cake or below 0.5% for dried powder. Excessive moisture increases shipping costs and can cause handling issues in cold climates (freezing). Buyers should specify if they require dried powder or wet filter cake, as the drying process adds to the energy cost and final price.

The most critical application is the production of Hydrofluoric Acid (HF), which serves as the precursor for fluorocarbons (refrigerants), fluoropolymers (like PTFE/Teflon), and lithium battery electrolytes (LiPF6). It is also used in the aluminum industry to produce aluminum fluoride, which acts as a flux to lower the melting point of alumina during smelting.

Suppliers must provide a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) from a reputable third-party inspector like SGS or Intertek. Since fluorspar is a mineral product, it must comply with IMDG codes if classified as hazardous during maritime transport, and buyers should ensure the supplier has a valid export license, especially in regulated markets like China.

Mineral quality can vary between batches. It is essential to mandate pre-shipment inspection (PSI) at the loading port. Use Made-in-China.com's Secured Trading services to ensure that payment is only released upon the presentation of a clean inspection report confirming the CaF2 purity and impurity thresholds.

Fluorspar prices are sensitive to environmental regulations and mining quotas. Buyers should negotiate formula-based pricing linked to market indices or secure long-term off-take agreements to stabilize costs.

Acidspar is often shipped in 1.5-ton jumbo bags (FIBCs) or in bulk carriers. If shipping in containers, ensure the use of container liners to prevent contamination and moisture ingress. For cross-border logistics, clarify the Incoterms (typically FOB or CIF); given the weight of the product, ocean freight volatility can significantly impact the landed cost.

China is a major producer, and the government often adjusts export duties or VAT rebate policies on mineral resources to protect domestic supply. Buyers must confirm whether the quoted price includes the export tax and ensure the supplier has the necessary environmental permits, as 'green' inspections can lead to sudden factory shutdowns and supply force majeure.
