Cod liver oil

When evaluating Cod Liver Oil, the most critical factors are the EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) content, as well as the levels of natural Vitamin A and Vitamin D3. High-quality oil should be extracted using cold-pressing or molecular distillation to preserve nutrient integrity and ensure the removal of heavy metals. Ensure the Total Oxidation Value (TOTOX) is below 26 to guarantee freshness and prevent rancidity.

For global trade, the product must adhere to GOED (Global Organization for EPA and DHA Omega-3) voluntary monographs. Depending on the target market, look for FDA registration (USA), EFSA compliance (EU), or TGA approval (Australia). Additionally, certifications like HACCP, ISO 22000, and GMP (Good Manufacturing Practice) are non-negotiable for food safety and quality management.

Request a Certificate of Analysis (COA) for every batch. This document should confirm that levels of mercury, lead, cadmium, and PCBs are well below international safety limits. Third-party testing from organizations like IFOS (International Fish Oil Standards) provides the highest level of transparency regarding purity, potency, and freshness.

Cod Liver Oil is highly sensitive to light and oxygen. It should be stored in amber glass bottles or opaque HDPE plastic containers with induction seals. For bulk shipments, nitrogen flushing is essential to displace oxygen in the headspace, preventing oxidation during long-transit times. Ensure the outer cartons are UV-protected and temperature-controlled if shipping through tropical climates.

Always request a pre-shipment sample from the same production lot you intend to purchase. Use Made-in-China.com's audit services to verify the supplier's production environment. It is also wise to include a clause in the contract stating that the TOTOX value must be verified by a third-party inspector (like SGS) at the port of loading.

Focus on long-term volume commitments rather than one-off purchases to secure better pricing. Negotiate based on the active ingredient concentration (EPA/DHA levels) rather than just the gross weight of the oil. Ask for tiered pricing where the unit cost decreases as your annual procurement volume grows.

Check the HS Code (typically 150410) for specific import duties in your country. Be aware that some regions require Health Certificates or Phytosanitary Certificates issued by the exporting country's authorities. Ensure all labels comply with local language requirements and include mandatory allergen warnings (e.g., 'Contains Fish').

Utilize secured payment terms such as Letter of Credit (L/C) or the Trade Assurance services provided by Made-in-China.com. Avoid making full payments upfront; a standard 30% deposit and 70% balance against the Bill of Lading (B/L) is a common and safer practice for established B2B buyers.
