What should a l-threonine RFQ specify?
State the chemical form, assay, activity or bio-equivalence basis, moisture, physical form, carrier where applicable, destination authorisation and the formulation basis used for comparison.
Also known as: L-Thr 98.5%
Third-limiting amino acid in swine and poultry after Lys and Met. 98.5% purity crystalline.
Compare origins on the same delivered basis for your discharge port and shipment window with the landed-cost calculator, then request offers through a reviewed RFQ.
Schemes buyers often ask suppliers to document for this ingredient — not a statement that any supplier holds them. FeedMatch asks for the current certificate in the RFQ; check that its scope covers the product and activity in the scheme's own register (see GMP+ and FAMI-QS).
These questions turn a broad market search into a comparable procurement brief. Values, doses, substitutions and performance expectations must be approved by the buyer's qualified nutrition, veterinary, feed-science, safety and regulatory advisers.
State the chemical form, assay, activity or bio-equivalence basis, moisture, physical form, carrier where applicable, destination authorisation and the formulation basis used for comparison.
Compare delivered cost per kilogram of active equivalent on the same formulation basis. Account for assay, product form, handling, freight, testing and any supplier-proposed equivalence factor.
Request a current specification, technical and safety data, recent batch certificates of analysis, manufacturing and feed-safety certification, destination registration where required, allergen or GMO status where relevant, traceability details, shelf-life evidence and a clear procedure for non-conforming lots. Verify documents and claims before approval.
The quoted result can change with feedstock or active-material availability, production concentration, plant outages, energy and freight costs, packaging, order size, Incoterm, destination registration, testing requirements and delivery window. FeedMatch does not publish a live price; buyers should request a firm, time-bound quotation against one controlled specification.
L-Threonine is bought inside the additives category, where specification discipline — not price per kilogram — decides the real cost. Our feed additives procurement guide covers how to write a quotable specification, which certifications and registrations to demand (FAMI-QS, GMP+, EU Reg. 1831/2003), when a premix beats buying straights, and how to normalise offers to delivered cost per unit of active.
Confirm the current rule for the exact product, target species and destination market before contracting. Private assurance schemes may support supplier qualification but do not replace applicable law.
Purity covers everything that should not be in the cargo — foreign matter, other-grain admixture, hulls, soil, packaging debris and deliberate adulterants — and is verified by physical inspection plus targeted analysis.
Every analytical result carries measurement uncertainty; contractual tolerances define how much variation is accepted before a price adjustment, rejection or claim is triggered.
The amino-acid profile — and above all digestible lysine, methionine, threonine and tryptophan — is what protein ingredients are actually bought for in modern formulation.
Shelf life is the period over which an ingredient retains its declared specification under defined storage conditions; it is a conditional statement, not a fixed property of the material.
Each parameter is explained in the specification library — what it measures, how it is tested and what to verify.
| Test | Why buyers run it |
|---|---|
| Assay / purity of the declared amino acid | Purity is the product; declared content drives least-cost inclusion |
| Loss on drying | Moisture dilutes the active and drives caking |
| Heavy metals and residual solvents where applicable | Safety compliance in the destination market |
| Particle size / bulk density | Dosing accuracy and segregation control |
Commonly 24 months or more when stored dry and sealed; hygroscopic forms such as liquid or hydrochloride salts have shorter, condition-dependent lives.

Purchase specification and commercial terms
Short answer: suppliers can only quote like-for-like when the specification and the commercial terms are written down. Use the two checklists below. Your nutritionist sets the nutrient values; this page does not suggest any limits, prices or tolerances.
| Product identity | Exact name, origin and process (e.g. solvent-extracted soybean meal), not a generic category. |
|---|---|
| Analytical specification | Parameters with limits and basis: protein, moisture, fat, fibre, ash or the key nutrient for that ingredient. |
| Contaminant limits | Mycotoxins, salmonella, heavy metals and residues under your local feed regulation. |
| Sampling and test method | Who samples, where (loading or arrival), how many samples, which laboratory and method. |
| Packaging and handling | Bulk, big bag or bags; storage and handling conditions in transit. |
| Documents per lot | Certificate of analysis, phytosanitary or health certificate and certificate of origin, as required. |
| Price basis | Price per tonne in one currency with an Incoterms® 2020 rule and named place (e.g. CIF named port). |
|---|---|
| Quantity and tolerance | Contract tonnage, delivery schedule and the agreed quantity tolerance. |
| Payment terms | Deposit, letter of credit or open account, and the documents that trigger payment. |
| Quality acceptance | Which analysis is final (loading or arrival), how a referee sample is resolved, and price adjustment or rejection rules. |
| Claims window | How many days after delivery a quality or quantity claim can be raised, and what evidence is needed. |
| Delivery and delay | Delivery window, who bears late-delivery costs and force majeure wording. |
| Validity | How long the offer stays valid and how price changes are handled for later deliveries. |
Compare offers on cost per kg of output, not price per tonne alone: a cheaper ingredient that worsens feed conversion can cost more per kg produced.
Calculators and checklists are free. Plant and equipment projects start from USD 250,000; ingredient and feed supply has no such minimum. Our team reviews each request before contacting suppliers. Incoterms® is a trademark of the International Chamber of Commerce.

What exactly am I buying?
How much, and at what landed cost?
Is this supplier and lot acceptable?
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.
≥98.5% purity, dust content <5%, free-flowing crystalline.
Mucin (goblet-cell glycoprotein) is ~30% Thr — adequate supply supports intestinal barrier.
Thr trades at 1.1–1.4× Lys HCl per kg.

How it works
| L-Threonine | Evidence to request |
|---|---|
| Product-specific specification | L-threonine identity and assay; fermentation traceability, moisture, impurities and mixing uniformity. |
Turn the product checks into a written specification approved by your technical team. Separate guaranteed contractual values from typical information; state units, moisture basis, analytical methods and tolerances. Request a dated, lot-linked certificate of analysis and representative sampling plan. Agree who releases the lot, what happens after an out-of-spec result, and how retained samples and claims are handled. A generic technical sheet is not evidence for the shipment you receive.
Use the same grade, quantity, named delivery place, Incoterm, currency and quote date. Separate product, freight, insurance, duties, testing, handling and payment costs; never count included freight twice or unknown charges as zero. Concentrates require an agreed active-content or activity basis. Moisture correction and nutritional equivalence must use measured analysis and qualified approval, not a kilogram-for-kilogram swap. Ask for quote validity and confirm inclusions before comparing totals.
State quantity and units per shipment, frequency, requested arrival window, packaging and unloading constraints. Record warehouse temperature/humidity needs, remaining shelf life at arrival, segregation and traceability requirements. Ask the team to obtain dated lead-time proposals and contingency terms; this is not a stock or supplier-availability claim. Product eligibility and import documents must be checked for the actual destination and animal species, not inferred from another market.
A lower ingredient invoice does not prove a lower cost of animal production. Use the FCR calculator with your own feed consumed, liveweight gain and complete-feed cost over the same period. Keep species, phase, feed basis and measurement method consistent. Do not attribute an FCR change to an additive without comparable evidence; the calculator evaluates inputs, not product efficacy. Any inclusion or reformulation decision belongs to your qualified nutritionist.
Buyer use is free. Ingredient and recurring feed supply are assessed by specification, viable volume/frequency, destination and logistics—not the plant/equipment capital minimum. FeedMatch reviews your request, contacts suitable suppliers and presents responses through the team; no direct buyer–supplier handoff and no guaranteed offers.
Send your specification, quantity and destination for human review; the US$250,000 minimum applies only to plant and equipment projects. FeedMatch reviews and organises your brief before contacting suitable suppliers, then presents responses through FeedMatch—not through direct buyer-to-supplier contact.
