Fish oil for feed manufacturers

When evaluating fish oil, the most critical factors are the EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) levels, which determine the nutritional value for the target species. You must also check the Acid Value (AV) and Peroxide Value (PV); a low PV (typically <5 meq/kg) indicates freshness and minimal oxidation. Additionally, ensure the Anisidine Value (AnV) is low to confirm the oil hasn't undergone secondary oxidation, which can cause rancidity and harm animal health.

Suppliers must adhere to strict safety standards. Look for GMP+ (Good Manufacturing Practices) or FAMI-QS certifications, which are the gold standards for specialty feed ingredients. For sustainability-conscious markets, IFFO RS (now MarinTrust) or MSC (Marine Stewardship Council) certifications are essential to prove the oil is sourced from responsible fisheries. Always request a Certificate of Analysis (COA) for every batch to verify heavy metal limits (like Arsenic, Lead, and Mercury) and Dioxin/PCB levels meet international safety thresholds.

The source fish (e.g., Anchovy, Menhaden, or Salmon) dictates the fatty acid profile. Anchovy oil is highly prized in Aquaculture (shrimp and carnivorous fish) for its high EPA/DHA ratio. For Poultry or Swine feed, crude fish oil is often used to improve caloric density and immune response. Ensure the supplier specifies the fish species and origin, as this impacts both the price and the biological efficacy of the feed.

Fish oil is highly susceptible to oxidation. Ensure the supplier adds Antioxidants (such as Ethoxyquin, BHA/BHT, or Natural Tocopherols) during production. For bulk shipping, the use of Flexitanks or ISO Tanks with nitrogen blanketing is recommended to displace oxygen. The product should be stored in a cool, dark environment to maintain a shelf life of typically 12 to 24 months.

Adulteration with cheaper vegetable oils or spent frying fats is a common risk. To prevent this, conduct Third-Party Inspections (such as SGS or Intertek) at the loading port to verify the Fatty Acid Profile via gas chromatography. Use Made-in-China.com’s secured trading services to ensure payment is only released after the quality inspection report is validated.

Fish oil prices are volatile and tied to global fish meal markets. Negotiate based on Total Omega-3 content rather than just gross weight. For long-term stability, consider Formula Pricing linked to market indices or lock in volumes during the peak fishing seasons (e.g., the Peruvian anchovy seasons) to secure lower rates. Always clarify Incoterms (FOB vs CIF) to understand who bears the risk during maritime transit.

Fish oil is classified as a biological product. You must ensure the supplier is registered with the customs authorities of the importing country (e.g., GACC registration for China or FDA for the USA). Verify that the Health Certificate issued by the exporting country's government matches the specific wording required by your local customs to avoid costly port delays or rejections.

Always verify the supplier's Business License and Export Permits. Utilize the Audit Reports and Diamond Member status on Made-in-China.com to identify reputable manufacturers. For first-time orders, use Letter of Credit (L/C) or Escrow-based payment terms to protect your capital against non-delivery or non-compliance.
