Spirulina powder

When evaluating Spirulina Powder, the most critical factor is the Protein Content, which should ideally be between 60% and 70%. Additionally, check for the Phycocyanin levels (the active antioxidant), which typically range from 10% to 18% in high-quality batches. The powder should have a deep, dark green color and a fine, uniform texture without clumps. Ensure the moisture content is below 7% to prevent microbial growth and ensure a shelf life of at least 24 months.

For global trade, suppliers must provide ISO 22000 or HACCP certifications to guarantee food safety management. If you are importing into the US, FDA Registration and GRAS (Generally Recognized as Safe) status are essential. For the EU market, compliance with EC No. 1881/2006 regarding heavy metal limits (Lead, Mercury, Cadmium) is mandatory. Furthermore, Organic Certifications (USDA Organic or EU Organic) and Kosher/Halal certificates significantly increase marketability and consumer trust.

Request a Certificate of Analysis (COA) for every batch. Specifically, look for third-party lab results testing for Heavy Metals (Lead < 2ppm, Arsenic < 1ppm) and Microbiological contaminants (Salmonella, E. coli, and Yeast/Mold). Because Spirulina is grown in water, it is vital to confirm the absence of Microcystins (cyanotoxins), which can occur if the cultivation ponds are contaminated with wild algae.

The most common and preferred method is Spray Drying, which preserves the heat-sensitive nutrients and pigments. Ensure the supplier uses a closed-loop cultivation system or strictly monitored open raceway ponds to minimize environmental pollutants. Ask if the supplier uses Low-Temperature Drying technology, as this better maintains the bio-activity of enzymes and vitamins compared to high-heat industrial drying.

The primary risk is Adulteration or Dilution with cheaper fillers or low-grade algae. To mitigate this, use Made-in-China.com's Secured Trading services and request a Pre-shipment Inspection (PSI) by agencies like SGS or Intertek. Another risk is Oxidation during transit; ensure the product is vacuum-sealed in aluminum foil bags and packed in fiber drums to protect it from light and moisture.

Standard MOQs for Spirulina Powder usually start at 25kg (one drum). For bulk orders exceeding 500kg to 1 ton, you can typically negotiate a 10-15% discount. When negotiating, focus on the Phycocyanin grade; higher grades command premium prices. It is advisable to request a paid sample (100g-500g) first to verify quality before committing to a large-scale contract.

Spirulina is classified under HS Code 210220 (Single-cell micro-organisms). Ensure your customs broker confirms the specific Import Duties in your country, as health supplements can attract higher tariffs. Because it is a food product, ensure the Labeling complies with destination country regulations, including ingredients, net weight, and 'Country of Origin' markings, to avoid customs seizures.

Always prioritize Audited Suppliers on Made-in-China.com who have undergone comprehensive on-site factory inspections. Use Escrow-based payment terms where funds are only released upon confirmation of shipping documents (Bill of Lading). Avoid direct wire transfers to private accounts; always ensure the beneficiary name matches the company name on the business license and proforma invoice.
