Short answer · reviewed August 2026
What is DL-Methionine 99% Feed Grade?
DL-methionine 99% feed grade is the crystalline synthetic form of the first limiting amino acid in poultry diets, traded at a minimum assay of 99.0% on a dry basis. It is normally dosed at 0.5–3.0 kg per tonne of finished feed depending on species, phase and the crude protein level of the formula. A comparable offer must state assay, moisture, form (crystalline powder vs the liquid MHA-FA alternative, which is not equivalent on a product-for-product basis), packaging, production date, Incoterm and named loading port.
DL-Methionine 99% — commercial specification
| Metric | Value | Unit | Basis |
|---|---|---|---|
| Assay (DL-methionine) | ≥ 99.0 | % w/w | CoA — state the analytical method |
| Loss on drying | ≤ 0.5 | % | CoA |
| Residue on ignition (ash) | ≤ 0.5 | % | CoA |
| Physical form | White to pale-yellow crystalline powder | — | Sample / photo of lot |
| Heavy metals (as Pb) | ≤ 10 | mg/kg | Test report |
| Arsenic | ≤ 2 | mg/kg | Test report |
| pH (5% solution) | 5.6–6.1 | — | CoA |

Documents a compliant offer must carry
- Certificate of Analysis (CoA) per batchThe only document that ties the delivered lot to the specification you contracted.
- GMP+ B2, FAMI-QS or equivalent feed-safety certificationRequired by most EU and Gulf buyers and by many mills' own HACCP plans.
- Certificate of OriginDrives duty treatment and, in several markets, import permit eligibility.
- Heavy-metal and dioxin/PCB statement or test reportFeed-safety limits are enforced at import; a missing report stops the container.
- Packing list with lot numbers and production dateLets you trace a claim to a specific lot and check remaining shelf life on arrival.
Packaging, Incoterms and container maths
- Packaging
- 25 kg multi-wall paper bag · 1,000 kg big bag (FIBC) · Palletised and shrink-wrapped
- Common Incoterms
- FOB · CFR · CIF · DAP for regional lanes
- Minimum order
- Commonly one full pallet for trial volume; producers and traders usually quote from 5 t
- Container loading
- 20 ft ≈ 20–22 t on pallets; 40 ft ≈ 24–25 t (volume-limited, not weight-limited)
- Lead time
- Ex-stock traders 1–3 weeks; direct producer allocation 4–10 weeks depending on plant
- Shelf life and storage
- 24 months from production in sealed original packaging, dry storage
Ask for production date, not just shipment date — bagged material that has sat in a hot warehouse cakes and complicates dosing. On CFR offers confirm whether demurrage and detention free time is included.
Who produces it
FeedMatch Group is independent and does not represent any producer. The landscape below is descriptive, not a ranking.
- Global integrated producersA handful of plants in Europe, Asia and North America set the reference price; they typically sell on allocation and quote annual or quarterly frames.
- Regional producersAdditional capacity in Asia competes hard on specific lanes and can be materially cheaper delivered, with the same 99% assay.
- Traders and distributorsHold local stock, sell in pallet quantities, and add a margin in exchange for short lead time and small lots.
