Sodium gluconate price manufacturers

When sourcing Sodium Gluconate, you must prioritize purity levels, typically requiring a content of ≥99.0% for industrial or food-grade applications. Pay close attention to the heavy metal content (Pb ≤10ppm) and arsenic levels (As ≤2ppm) to ensure safety. Additionally, verify the pH value (6.5-7.5) and loss on drying (≤0.5%), as these factors directly impact the chemical's stability and performance in concrete admixtures or cleaning agents.

The price is heavily influenced by the grade: Technical Grade is cost-effective for construction (as a high-efficiency retarder) and water treatment, while Food Grade or Pharmaceutical Grade commands a premium due to stricter FCC (Food Chemicals Codex) or USP compliance. For B2B buyers, selecting a Tech Grade with high chelating power is usually the most economically feasible choice for large-scale industrial use.

A reputable supplier should hold ISO 9001:2015 for quality management and ISO 14001 for environmental standards. If you are importing for food or beverage industries, ensure the supplier provides HACCP, KOSHER, or HALAL certifications. For European markets, REACH registration is mandatory to ensure the chemical meets regional safety and environmental regulations.

Sodium Gluconate is widely used as a set retarder and water reducer in the construction industry to improve concrete workability. It is also a superior chelating agent in industrial cleaning (bottle washing, metal surface cleaning) and textile dyeing, where it prevents scale formation and metal ion interference. Understanding your specific end-use concentration requirements will help in negotiating the right particle size (fine powder vs. granular) with the supplier.

The price of Sodium Gluconate is sensitive to raw material costs (glucose/corn starch) and energy prices. To secure a stable supply, consider long-term framework agreements or formula-based pricing tied to market indices. Always request a Proforma Invoice (PI) that specifies the validity period of the quote to avoid sudden price hikes during the negotiation phase.

Always use secure payment methods such as Letter of Credit (L/C) for large volumes or Escrow services provided by reputable platforms like Made-in-China.com. Before full payment, insist on a Pre-shipment Inspection (PSI) by third parties like SGS or Intertek to verify the Certificate of Analysis (COA) against the actual cargo.

Sodium Gluconate is generally classified as non-hazardous, but it is hygroscopic. Ensure the supplier uses moisture-proof packaging, such as 25kg PP bags with PE inner liners or 1000kg jumbo bags. For sea freight, request palletized loading with shrink wrap to prevent bag breakage and moisture ingress during transit, especially for long-haul cross-border shipping.

Verify the HS Code (typically 2918160000) with your local customs office to determine the applicable import tariffs and VAT. Check if your country has anti-dumping duties on Chinese chemicals. Utilizing a supplier on Made-in-China.com who is an Audited Supplier can help ensure that all export documentation, including the Country of Origin certificate, is accurate to facilitate smooth customs clearance.
