Sodium chloride salt price manufacturers

Sodium Chloride is categorized by purity and additives. Industrial Grade (96-97% purity) is used for de-icing and chemical manufacturing; Food Grade (99% min purity) must meet FCC or Codex Alimentarius standards and often contains anti-caking agents like Sodium Ferrocyanide; Pharmaceutical Grade (99.9% purity) requires strict GMP certification and compliance with USP/EP/BP pharmacopoeia for use in IV fluids or dialysis.

The price is primarily driven by purity levels, moisture content (ideally <0.1% for high grade), and particle size distribution (fine, medium, or coarse). Additionally, the presence of water-insoluble matter and heavy metals (like Lead or Arsenic) significantly affects the valuation, especially for food and medical applications.

For international trade, ensure the supplier provides an ISO 9001 for quality management. If purchasing for food use, HACCP, ISO 22000, or Halal/Kosher certifications are essential. For industrial use, a comprehensive COA (Certificate of Analysis) and MSDS (Material Safety Data Sheet) are mandatory for customs and safety handling.

Vacuum Salt (refined from brine) offers the highest purity and uniform grain size, making it ideal for chemical and food industries. Sea Salt (solar evaporation) contains more trace minerals but may have higher impurities. Rock Salt (mined) is generally the most cost-effective for large-scale industrial applications like water softening or road de-icing.

Sodium Chloride is highly corrosive and hygroscopic (absorbs moisture). You must ensure the use of moisture-proof PE/PP woven bags (typically 25kg or 1000kg jumbo bags). For sea freight, verify that the container is dry and clean to prevent caking or contamination, and consider FOB terms to maintain better control over the shipping environment.

Always utilize Trade Assurance services or Letters of Credit (L/C) for large volume orders. Before full payment, hire a third-party inspection agency like SGS or Intertek to perform pre-shipment inspection (PSI) to verify the weight and chemical purity against the agreed-upon specifications.

Check for anti-dumping duties or specific import quotas on salt in your destination country. Some regions have strict iodization mandates for edible salt; importing non-iodized salt for food use may lead to customs rejection. Consult with a customs broker on Made-in-China.com to clarify the HS Code (typically 250100) requirements.

Salt is a low-margin commodity where logistics costs often exceed the product value. Negotiate based on annual volume commitments rather than spot buys to secure a lower unit price. Ask for tiered pricing and explore suppliers on Made-in-China.com who are located near major ports to minimize inland transit costs.
