Gluconate calcium

Calcium Gluconate is primarily categorized into Pharmaceutical Grade (USP/BP/EP), Food Grade (FCC), and Injection Grade. For medical applications, it must meet USP (United States Pharmacopeia) or EP (European Pharmacopoeia) standards. For the food industry, it is used as a mineral supplement and firming agent, requiring FCC (Food Chemicals Codex) compliance. Always verify the Assay value (typically 99.0% to 102.0%) and limits on heavy metals (Lead ≤ 2ppm, Arsenic ≤ 3ppm).

Buyers should focus on solubility parameters, as Calcium Gluconate is slowly soluble in cold water but more soluble in boiling water. Check the pH value (6.0 to 8.0 in a 5% solution) and Loss on Drying (not more than 0.5% for anhydrous forms). For liquid formulations, the clarity and color of the solution are vital indicators of purity. Ensure the supplier provides a detailed Certificate of Analysis (COA) for every batch.

A professional manufacturer must hold GMP (Good Manufacturing Practice) certification for pharma-grade products. For food-grade exports, ISO 22000 or HACCP certifications are essential. If targeting specific markets, look for HALAL and KOSHER certifications. For European market entry, ensure the supplier is compliant with REACH regulations.

The mesh size (typically 20-80 mesh for granules or 100+ mesh for powder) significantly impacts the dissolution rate and blending uniformity. Fine powders are preferred for tablet compression and fortifying beverages, while granular forms are often used in capsule filling to improve flowability and reduce dust.

Utilize Secured Trading Services provided by reputable platforms like Made-in-China.com to ensure payment safety. Always conduct a Third-Party Factory Audit (e.g., SGS or Intertek) to verify the supplier's production capacity and quality management system before placing large orders.

Focus on Volume-Based Pricing Tiers; for Calcium Gluconate, price breaks often occur at 1 ton, 5 tons, and 10+ tons (FCL). Negotiate for Free Samples (50g-100g) to conduct lab testing before bulk commitment. Request Price Protection Clauses in long-term contracts to hedge against raw material price fluctuations.

Standard packaging is usually 25kg paper bags or fiber drums with PE inner liners. Since it is sensitive to moisture, ensure the container is shipped in a dry environment and request palletization with shrink wrap to prevent damage during transit. For sea freight, clarify the Incoterms (FOB or CIF) to define responsibility for insurance and local port charges.

Verify the HS Code (typically 291816) to check for specific import duties or anti-dumping taxes in your country. Ensure all documentation, including the Commercial Invoice, Packing List, COA, and Bill of Lading, matches perfectly to avoid Customs clearance delays.
