Calcium gluconate monohydrate powder wholesale refers to the bulk purchase of the white, crystalline calcium salt of gluconic acid, typically used in pharmaceutical, food, and nutraceutical applications. Buying in wholesale quantities requires attention to purity, particle size, and regulatory compliance to ensure consistent production outcomes.
What specifications matter when buying calcium gluconate monohydrate powder wholesale?
Key specifications include assay (typically 98.5–102.0% on a dried basis), loss on drying (7.5–9.5% for the monohydrate), heavy metal limits, and microbial counts. Particle size distribution also affects flowability and dissolution, so confirm mesh or micron ranges before ordering.
Pharmaceutical-grade material should meet USP, EP, or BP monographs, while food-grade follows FCC or E-number standards. Request a Certificate of Analysis (COA) for each lot to verify these parameters.
How do you choose a reliable calcium supplier in China?
China is a major producer of calcium salts, with many manufacturers concentrated in provinces like Shandong and Jiangsu. When vetting a calcium manufacturer or calcium supplier, check GMP, ISO 9001, and halal/kosher certifications if relevant. Ask for samples, audit reports, and references from existing bulk buyers.
For calcium gluconate monohydrate powder wholesale, a supplier with stable production capacity and transparent quality documentation reduces supply-chain risk. Confirm lead times, minimum order quantities, and packaging options (e.g., 25 kg fiber drums with food-grade liners).
What factors influence wholesale pricing?
Pricing depends on order volume, purity grade, packaging, and shipping terms (FOB, CIF, or DDP). Market demand for calcium salts and raw material costs for gluconic acid also shift quotes. Always compare landed cost, not just unit price, and clarify payment terms and inspection rights.
常见问题
What is the typical minimum order quantity for calcium gluconate monohydrate powder wholesale?
Minimum order quantities vary by supplier, but many manufacturers set MOQs between 100 kg and 1,000 kg for bulk powder. Smaller trial orders may be possible at a higher unit cost. Always confirm MOQ and packaging details before requesting a quote.
How should I store calcium gluconate monohydrate powder in bulk?
Store in a cool, dry, well-ventilated area away from moisture and strong oxidizers. Keep containers tightly sealed to prevent caking or microbial growth. Shelf life is typically 2–3 years when stored properly.
Can I get a sample before placing a wholesale order?
Yes, most reputable suppliers offer small samples (e.g., 100 g to 1 kg) for evaluation, sometimes free or at a nominal cost plus shipping. Use samples to verify assay, particle size, and solubility against your requirements before committing to bulk.
