Feed and feed inputs

Amino acids

Feed-grade amino acids bought on assay, form and active content.

How should amino acid offers be compared?

Compare them on active-substance content rather than product weight, with the product form (dry or liquid), a certificate of analysis per batch and the registration or authorisation status in the destination country.

Evonik Methionine (buying guide)
Most buyers searching for Evonik methionine are doing one of three things: confirming which grade sits behind a quoted brand name, checking what a compliant offer must document, or benchmarking a producer price against the other qualified methionine sources. This page covers the specification you should state in an RFQ, the alternatives that are genuinely comparable once you normalise to cost per kilogram of methionine, and the fields that make an offer straightforward to quote.

What a supplier must document

FeedMatch asks for these before an offer is presented to you. Anything a supplier has not documented stays marked as missing — it is never estimated.

Supplier-document review checklist

How to read this catalog. Each entry is a product type FeedMatch sources for commercial buyers, with an independent buying guide. It is not a listing of stock, prices or supplier offers. Nutrition values, formulations, origins, certifications and availability are shown only when a supplier has documented them, and stay labelled as supplier-declared until checked against the documents. FeedMatch is a sourcing intermediary — it does not manufacture, sell or export feed or equipment, and gives no veterinary or nutritional advice; ask your nutritionist or veterinarian about suitability.

Feed and ingredient requests have no minimum; assisted sourcing for plant and equipment projects applies from about USD 250,000. Requests go to the FeedMatch team, who contact suppliers and present responses — buyers and suppliers are not put in direct contact.

Availability and the ability to trade depend on the applicable law and on the licences and approvals required, which differ by product and country. Each participant is responsible for the rules that apply to its own role: suppliers for the products they offer and supply, buyers for their own import permissions and checks. FeedMatch is not a manufacturer, importer, exporter, seller or regulatory approver; it facilitates sourcing and screens requests before any supplier is contacted. Regulation & responsibilities.
