Sodium polyacrylate price

When sourcing Sodium Polyacrylate, the price is heavily influenced by its absorbency rate (g/g) and particle size distribution. For industrial grades, ensure the residual monomer content is below 500ppm, while for hygiene grades (SAP), it must be below 100ppm. You should also verify the pH value (typically 6.0-9.0) and the moisture content (usually <5%), as these factors directly impact the shelf life and performance efficiency of the polymer.

The price varies significantly based on the intended use. Hygiene Grade (SAP) for diapers requires high Absorbency Under Load (AUL) and commands a premium. Agricultural Grade focuses on water retention and soil conditioning, often priced lower but requiring biodegradability certifications. Industrial Grade used for thickening or wastewater treatment is generally the most cost-effective. Always specify your application scenario to the supplier to avoid paying for unnecessary high-spec performance.

To ensure safe cross-border trade, request the Material Safety Data Sheet (MSDS) and Technical Data Sheet (TDS). For food-contact or medical applications, compliance with FDA (21 CFR 173.310) or REACH (EU) is mandatory. If you are sourcing from Made-in-China.com, look for Audited Suppliers who hold ISO 9001 for quality management and ISO 14001 for environmental standards to ensure consistent batch quality.

Economic feasibility is best achieved through volume-based pricing tiers. Typically, ordering in Full Container Loads (FCL) can reduce the unit price by 15-20% compared to LCL. Additionally, consider the packaging format; sourcing in 25kg valve bags is standard, but 800kg-1000kg jumbo bags can further reduce labor and handling costs at your facility.

The biggest risk is moisture absorption during transit, which causes clumping and renders the product unusable. Ensure the supplier uses moisture-proof PE inner lining and palletized packaging with shrink wrap. Another risk is customs classification errors; ensure the correct HS Code (typically 390690) is used to avoid delays or incorrect duty applications.

Focus on long-term contract pricing rather than spot prices, as chemical raw material costs fluctuate with petroleum markets. Request a pre-shipment sample from the actual production batch and use Third-Party Inspection (like SGS or Intertek) to verify that the bulk cargo matches the sample's absorbency and purity levels before final payment.

Utilize Secured Payment services provided by reputable platforms like Made-in-China.com to ensure funds are only released upon proof of shipment. For large-scale orders, a Letter of Credit (L/C) is recommended. Always verify the supplier's Business License and Export Permit to ensure they are a legitimate manufacturer and not an unlicensed middleman.

Sodium Polyacrylate is generally classified as non-hazardous for transport, but you must provide a Non-Hazardous Chemical Declaration to the shipping line. For sea freight, choose FOB terms if you have a preferred forwarder to control costs, or CIF if you want the supplier to handle insurance. Ensure the container is stored away from heat sources and kept in a dry, ventilated area upon arrival.
