Zeolite 4a price

The price of Zeolite 4A is primarily driven by its Calcium Ion Exchange Capacity (≥295 mg CaCO3/g) and Whiteness (≥95%). Buyers should also verify the Particle Size (D50), which typically ranges from 3 to 5 microns for detergent applications. A lower Liquid Carrying Capacity or high Grit Content (>0.1%) can significantly reduce the product's value and performance in automated production lines.

Zeolite 4A is most commonly used as an eco-friendly builder in detergents to replace phosphates. It is also utilized in PVC stabilizers and molecular sieves. Because it is a bulk commodity, prices are sensitive to the cost of raw materials like Sodium Aluminate and Sodium Silicate. Procurement professionals should monitor these upstream chemical markets to time their bulk purchases effectively.

Suppliers should provide ISO 9001:2015 certification for quality management. For environmental safety, ensure the product is REACH compliant (for EU markets) and has a valid Material Safety Data Sheet (MSDS). Since it is often used in household chemicals, verifying that the product is heavy metal-free (Lead, Arsenic, Mercury) is critical for consumer safety and regulatory approval.

Buyers should perform a Cost-to-Performance analysis. While 'Detergent Grade' is cheaper, 'Molecular Sieve Grade' requires higher purity and specific pore sizes, commanding a premium. Requesting a Certificate of Analysis (COA) for every batch is essential to ensure the Loss on Ignition (LOI <20%) is within limits, as excess moisture means you are paying for water weight rather than active material.

The most significant risk is moisture absorption during sea transit, which can cause caking and reduce ion-exchange efficiency. Ensure the supplier uses moisture-proof PP woven bags with PE inner liners or Jumbo bags (500kg-1000kg) with UV protection. Another risk is quality inconsistency between the sample and the bulk shipment; always use a third-party inspection service (like SGS or Intertek) to test the cargo at the loading port.

Negotiate based on Annual Volume Commitments rather than one-off spot buys to secure a 5-10% discount. For payment, utilize Trade Terms like FOB or CIF and prioritize Letter of Credit (L/C) or Escrow services provided by reputable platforms like Made-in-China.com to ensure payment is only released upon proof of shipment. Ask for 'Tiered Pricing' where the unit price drops as the number of containers increases.

Zeolite 4A is generally classified as non-hazardous cargo, but it requires dry, ventilated storage. When shipping to countries with high humidity, request desiccants inside the container. Ensure the supplier provides a Non-Hazardous Chemical Declaration to avoid customs delays. For cost-efficiency, aim for Full Container Load (FCL) shipments, as Less than Container Load (LCL) increases the risk of contamination from other goods.

Look for the 'Audited Supplier' badge, which indicates the supplier has undergone a physical factory audit. Check their Export Experience—suppliers who have exported to your specific region for over 5 years are more likely to understand your local customs requirements. Review their Transaction History and response rate to ensure they have the operational capacity to handle large-scale industrial orders.
