Vitamin a 500 feed grade

The '500' typically refers to a potency of 500,000 IU/g. You must verify the activity level through a Certificate of Analysis (COA). Key forms include Vitamin A Acetate or Palmitate, usually provided as cross-linked beadlets (micro-encapsulated) to ensure stability against heat, moisture, and oxidation during the feed premixing and pelleting processes.

Suppliers must hold FAMI-QS (Feed Additives and Pre-Mixtures Quality System) or ISO 22000/HACCP certifications. For entry into the EU, EFSA compliance is required, while the US market requires FDA registration and adherence to the FSMA (Food Safety Modernization Act). Always request a Material Safety Data Sheet (MSDS) to confirm handling protocols.

Feed grade Vitamin A should have excellent flowability and low dust content to ensure uniform mixing in premixes. The particle size distribution should be consistent to prevent segregation. Cold-water dispersible (CWD) or starch-coated versions are preferred depending on whether the application is for dry feed or liquid supplements.

Vitamin A is highly sensitive to light and air. Standard shelf life is 24 months from the date of manufacture if stored in unopened original packaging. It must be kept in a cool (below 15°C), dry, and dark environment. Once the seal is broken, the degradation rate increases significantly, affecting the nutritional potency.

Request vacuum-sealed aluminum foil bags inside fiber drums to provide a barrier against oxygen and moisture. For trans-equatorial shipping, utilize reefer containers (refrigerated) or ensure the cargo is stowed below the waterline on the vessel to avoid extreme temperature fluctuations that cause thermal degradation.

Vitamin A prices are volatile due to raw material costs (like citral). Negotiate based on volume-based pricing tiers and consider long-term supply contracts with a price-adjustment formula. Always verify if the supplier is a primary manufacturer or a trader; sourcing directly from manufacturers on platforms like Made-in-China.com can reduce costs by 10-15%.

Use Letters of Credit (L/C) for large volumes to ensure payment is only released upon presentation of valid shipping documents and third-party inspection reports (e.g., SGS or Intertek). For initial smaller orders, utilize secured payment services provided by reputable B2B platforms to protect your funds until delivery confirmation.

Beyond the standard Invoice and Packing List, you will need a Health Certificate, a Certificate of Origin, and a Non-GMO Declaration if applicable. Ensure the HS Code (typically 2936.21) is correctly declared to avoid tariff penalties or customs seizures.
