Adisseo: Supplier Profile for Feed Buyers

Adisseo is one of the small group of global producers that set the reference price for methionine. Most buyers arriving on this page are doing one of three things: verifying which product and specification sits behind a quoted brand name, checking what documentation a compliant offer must carry, or benchmarking a direct producer price against competing producers and traders. This profile covers all three, then hands you a structured RFQ so the comparison is on landed cost, not list price.

Short answer · who Adisseo is and what it means for your order

Adisseo is a French-headquartered feed additive producer (Antony, France), owned by Bluestar / China National Bluestar within the ChemChina group, and one of the few global producers of methionine — sold as dry DL-methionine and as a liquid hydroxy-analogue (OH-methionine, HMTBa) — alongside enzymes, antioxidants and specialty nutrition products. For buyers the practical question is not the brand but the grade: a ≥99% DL-methionine offer from any audited producer is comparable on assay, CoA and landed cost, which is what this profile and the linked grade pages let you check.

Manufacturing footprint — and why origin changes your offer

Publicly reported production sites. The plant behind a quote drives freight, lead time, duty treatment and import documentation, so ask for the producing site by name rather than accepting the brand alone.

Site	Location	Reported output	Buyer note
Commentry	Allier, France	Methionine and intermediates (historic French methionine site)	European-origin material; ask whether your parcel actually ships from a French site or from Asia.
Les Roches-Roussillon	Isère, France	Methionine chemistry and intermediates	French origin can matter for EU customers on duty, carbon reporting and lead time.
Burgos	Castile and León, Spain	Feed additive production for the European market	Often the shortest intra-EU lane; confirm pack format availability from the site.
Nanjing	Jiangsu, China	Liquid methionine (hydroxy-analogue) capacity serving Asia and export markets	Asian origin usually wins on freight to Asia and Africa; check import registration and labelling.

Site list compiled from public company information; confirm the producing plant on the offer and CoA before award.

Raw materials behind the product — and what moves the price

The feedstocks upstream of the finished additive explain most of the quarter-to-quarter movement in offers. Knowing them lets you challenge a price increase with a question instead of accepting it.

Input	Role in the product	Buyer note
Propylene → acrolein	Carbon backbone of the methionine molecule; acrolein is produced by catalytic oxidation of propylene.	Propylene tracks crude and naphtha, so oil-price swings feed into methionine offers with a lag of roughly one quarter.
Methanol + sulfur → methyl mercaptan	Supplies the sulfur group that makes methionine a sulfur amino acid.	Sulfur and methanol availability is the usual bottleneck cited when producers declare allocation.
Hydrogen cyanide (HCN) or ammonia/CO₂ route	Introduces the amino/nitrile function; the route chosen determines whether the plant yields DL-methionine or the hydroxy-analogue.	Hazardous-intermediate handling is why methionine capacity sits with a handful of producers rather than many small plants.
Energy and utilities (steam, power, cooling)	Continuous chemical process with high energy intensity per MT.	European energy prices moved EU-origin methionine cost materially in recent years — one reason to compare EU and Asian origin on the same RFQ.
Packaging and carriers	25 kg bags and 1 MT big bags for dry product; corrosion-rated IBC / ISO tank for the liquid analogue.	Pack format is a real cost line — ask for the price both in big bags and 25 kg bags before you compare.

How the product is manufactured, step by step

A simplified public description of the production route. Each stage leaves a trace on the certificate of analysis, so it tells you which numbers to check on an offer.

1 · Intermediates
Acrolein from propylene oxidation and methyl mercaptan from methanol plus sulfur are produced or bought in on site.
Why it matters: Integrated producers making their own intermediates are less exposed to spot intermediate prices, which shows up in contract stability.
2 · Addition and hydantoin / nitrile chemistry
The intermediates are combined and reacted with a cyanide or ammonia source to build the methionine skeleton.
Why it matters: This is the step that splits the product tree: hydrolysis of the hydantoin gives DL-methionine, the alternative route gives the hydroxy-analogue.
3 · Hydrolysis and neutralisation
The intermediate is hydrolysed and neutralised into crude methionine solution.
Why it matters: Residual salts from this stage drive the ash and chloride figures you should see on the CoA.
4 · Crystallisation, separation, drying
Dry DL-methionine is crystallised, centrifuged and dried to a free-flowing crystalline powder; the liquid line is instead concentrated to an aqueous solution.
Why it matters: Crystal habit and drying set bulk density, flowability and dust — the practical difference between a smooth and a troublesome mill intake.
5 · QC release and packing
Assay, moisture, ash, heavy metals and microbiology are tested per lot before the batch is released and packed.
Why it matters: Insist the CoA is lot-specific and testing methods are named; a typical-values data sheet is not a release document.

Standards, regulation and the documents that prove them

Standard / regulation	What it requires	How to verify it on an offer
EU Regulation (EC) No 1831/2003	Methionine is an authorised nutritional feed additive; the label must carry the additive number, active content and the approval holder or authorised producer.	Ask for the EU authorisation reference used on the label and check the additive appears in the EU Register of Feed Additives.
FEEDAP / EU Catalogue purity criteria	Minimum assay ≥ 99.0% DL-methionine on a dry basis with defined limits on loss on drying, ash and residues.	The spec sheet should state each limit as a maximum or minimum, not a 'typical value'.
AAFCO / US feed-grade practice	Equivalent assay definition and labelling for material sold into the United States.	For US delivery ask which standard the CoA is issued against — EU and US spec sheets are not always identical.
Reference test methods (HPLC / titration, Karl Fischer, ICP-MS)	Assay by HPLC or titration, moisture by loss on drying or Karl Fischer, heavy metals (Pb, Cd, As, Hg) by ICP-MS or AAS.	A compliant CoA names the method next to each result; unmethoded numbers cannot be arbitrated in a dispute.
Undesirable substances — Directive 2002/32/EC	Heavy metals, dioxins and dioxin-like PCBs within the maximum levels for feed materials and additives.	Request the dioxin and heavy-metal statement for the shipping lot, plus the monitoring frequency behind it.
FAMI-QS / GMP+ FSA	The producing site — not only the head office — must be inside the certificate scope.	Match the site address on the certificate to the origin declared on the offer and the CoA.

Regulatory references are given for orientation; confirm the current authorisation and limits applicable in your import market before contracting.

Volume and capacity reality per line

Publicly reported scale, translated into what it means for a mill placing a real parcel. Figures are indicative orders of magnitude, not company disclosures.

Global methionine market

Publicly reported industry demand is on the order of 1.5–2 million MT per year, supplied by a small group of producers of which Adisseo is one of the largest.

A concentrated supply base means allocation, not price alone, is the real risk in a tight quarter — qualify a second producer before you need one.

Dry DL-methionine

Multi-hundred-thousand-MT annual capacity across the group's European and Asian assets, sold in FCL parcels upward.

Volumes below one container usually route through a distributor at a premium; consolidate quarterly demand into a single tender.

Liquid OH-methionine (HMTBa)

Dedicated liquid capacity including the Nanjing site serving Asia and export markets.

Liquid only pays back when you already have corrosion-rated storage and a calibrated dosing line — otherwise compare on dry equivalent.

Enzymes, antioxidants and specialties

Pallet-to-part-container volumes rather than bulk chemical scale.

These lines are formulation-specific; ask for the technical data sheet and a trial quantity before contracting annual volume.

Product lines and buyer specifications

Product	Specification to state in the RFQ	Packaging	Typical parcel	Buyer note
Dry DL-methionine	≥ 99.0% DL-methionine, free-flowing powder/crystalline, moisture ≤ 0.5%, heavy metals per feed-grade limits	25 kg bags, 1 MT big bags	1 × 20' FCL (approx. 20–22 MT) upward; blended into premix or dosed directly	The most widely traded form. Directly comparable across producers on assay, moisture and residue limits.
Liquid OH-methionine (hydroxy-analogue, HMTBa)	Typically 88% activity in aqueous solution; corrosive handling class; dosing requires calibrated liquid line	Drums, IBCs, bulk ISO tank	IBC lots up to bulk tank; requires on-site liquid storage and dosing	Not a 1:1 substitution with dry methionine — convert on bio-efficacy and adjust inclusion before comparing price per MT.
Feed enzymes	Activity units per gram declared on CoA; thermostability class matters for pelleting temperature	20–25 kg bags	Pallet lots; often ordered alongside premix	Compare on declared activity retained after your actual conditioning temperature, not label activity.
Antioxidants and specialty nutritional additives	Active content, carrier and shelf life per product data sheet	Bags and drums	Pallet to part-container	Highly formulation-specific — request a technical data sheet before treating any offer as equivalent.

Adisseo versus a multi-supplier tender

Criterion	Adisseo direct	Qualified alternatives	What it means for you
Product assurance	Global producer with consistent assay and well-documented CoA history	Other majors (Evonik, Novus, Sumitomo, CJ Bio for adjacent amino acids) plus qualified regional producers	For ≥99% DL-methionine the specification is the contract — brand alone should not carry a large premium
Price discovery	One quote, usually a list or contract price via a distributor	Parallel bids from several producers and traders on the same spec	Multi-supplier tenders typically surface the real market level on the quarter
Lead time flexibility	Depends on local stock and allocation during tight markets	Alternative origins can cover a gap when one producer is allocated out	A second qualified source protects mill continuity
Landed cost visibility	Often quoted EXW or FCA — freight, duty and clearing added later	FeedMatch normalises every bid to CIF/landed cost per MT	Apparent price gaps often reverse once freight, duty and payment terms are included
Documentation and compliance	Strong certification package as standard	Varies — must be verified per producer and per lot	Make CoA, FAMI-QS/GMP+ and import documentation a mandatory bid condition for every bidder

Buyer checklist before you award

Fix the specification first: product form, minimum assay, moisture and residue limits.
State the delivery term you want compared — CIF named port beats EXW for like-for-like evaluation.
Require batch CoA and a valid FAMI-QS or GMP+ certificate covering the producing site.
Convert liquid OH-methionine offers to a dry-equivalent basis before comparing price per MT.
Ask for the origin and producing plant, not just the brand name on the offer.
Define parcel size and shipment schedule — spot single-container pricing differs from a quarterly contract.
Agree payment terms and inspection (SGS/Bureau Veritas) before award, not after.
Run at least three qualified bidders on the same document set.

Brand-neutral grade specifications

The exact grades buyers order, specified independently of any producer — assay, documents, packaging and Incoterms — so a Adisseo offer can be compared like for like.

Frequently asked questions

Does FeedMatch Group sell Adisseo products?

No. We are an independent procurement platform and not a reseller or agent. We take your specification to audited producers and traders — specialist additive groups included where they choose to quote — and return every bid normalised to landed cost.

What does Adisseo actually supply for feed buyers?

The range centres on methionine — dry DL-methionine and a liquid hydroxy-analogue (OH-methionine / HMTBa) — plus enzymes, antioxidants and specialty nutritional additives. Availability, pack formats and route to market differ by region.

Is dry DL-methionine from another producer equivalent?

For ≥99% feed-grade DL-methionine the material is defined by specification, so offers from other qualified producers are comparable when assay, moisture, residue limits and certification match. Verify the producing site and batch CoA rather than assuming equivalence from the label.

How do I compare liquid OH-methionine against dry methionine?

Convert to a dry-methionine-equivalent basis using the bio-efficacy assumption your nutritionist accepts, then add handling costs — liquid product needs corrosion-rated storage and a calibrated dosing line. Comparing headline price per MT without that conversion is misleading.

Which suppliers are alternatives to Adisseo for methionine?

Other global producers include Evonik, Novus International and Sumitomo, with CJ Bio, Meihua and Ajinomoto strong in adjacent amino acids such as lysine and threonine. Qualified regional producers and traders can also be competitive on specific lanes.

What lead time should I plan for?

Roughly 2–4 weeks intra-Europe, 3–6 weeks CIF Asia, 4–8 weeks CIF Latin America and 5–9 weeks to most African ports, driven by sailing schedules, permits and pre-shipment inspection. Build a buffer during allocation periods.

What documents should I demand with every offer?

Batch certificate of analysis, valid FAMI-QS or GMP+ certificate covering the producing site, heavy-metal and dioxin statements where applicable, packing and origin details, and any import permit support your country requires.

Can FeedMatch benchmark a price I already have?

Yes. Send the specification, parcel size, delivery term and destination port and we will run the same document set through competing suppliers so you can see where your existing quote sits on landed cost.
