Hplc fucoxanthin price manufacturers

When sourcing Fucoxanthin, the purity level (typically ranging from 1% to 50%) is the most critical factor affecting price. You must ensure the product is tested via High-Performance Liquid Chromatography (HPLC) rather than UV-VIS to guarantee accuracy, as UV-VIS often overestimates concentration. Additionally, verify the physical form (oil vs. powder) and the source material (e.g., Undaria pinnatifida or Laminaria japonica), as these impact bioavailability and application suitability.

For B2B buyers, ensuring the supplier holds ISO 22000 or HACCP certifications is essential for food-grade safety. If the product is intended for the US market, FDA registration and GRAS (Generally Recognized as Safe) status are vital. For European markets, compliance with Novel Food regulations may be required. Always request a Certificate of Analysis (COA) and a Material Safety Data Sheet (MSDS) for every batch.

Fucoxanthin is highly sensitive to light, heat, and oxidation. To maintain potency, it must be stored in airtight, light-proof containers at low temperatures (typically <5°C or frozen). During cross-border transit, you should negotiate cold-chain logistics or vacuum-sealed aluminum foil packaging to prevent degradation, which could otherwise lead to a significant drop in active ingredient concentration upon arrival.

The price is primarily driven by the extraction efficiency and the concentration of the active compound. Bulk orders (e.g., >25kg) typically see a price reduction of 15-25% compared to small lab samples. Buyers should also account for the extraction solvent used (ethanol is preferred over hexane for 'clean label' requirements), as high-purity, solvent-residue-free products command a premium price but offer better marketability.

To ensure quality, always request a pre-shipment sample for independent third-party testing (e.g., SGS or Eurofins). Utilize Made-in-China.com's Secured Trading services to hold payment in escrow until the lab results confirm the HPLC purity matches the contract specifications. Avoid suppliers who refuse to provide batch-specific chromatograms.

Focus negotiations on long-term supply stability and purity consistency rather than just the lowest unit price. Ask for tiered pricing based on annual volume commitments and negotiate for 're-test' clauses, where the supplier bears the cost of return or replacement if the product fails your internal QC within 15 days of receipt.

For high-value extracts like Fucoxanthin, Air Freight (via DHL, FedEx, or specialized chemical couriers) is recommended to minimize transit time. Ensure the commercial invoice uses the correct HS Code (typically 3203.00 or 2932.99) to avoid customs delays. For large volumes, ensure the supplier provides temperature-controlled containers (reefers) if sea freight is used.

Always conduct supplier audits to verify if the company is a manufacturer or a middleman; manufacturers on Made-in-China.com with 'Audited Supplier' status provide higher reliability. Use Letter of Credit (L/C) or Telegraphic Transfer (T/T) with a deposit/balance split (e.g., 30/70) to maintain leverage until the Bill of Lading is provided.
