A source-linked European profile of propulsion-grade ammonium perchlorate synthesis, conditioning, upstream dependence, qualification and expansion evidence.
Where can Europe synthesize and condition propulsion-grade ammonium perchlorate, and what evidence would establish qualified, expandable and uncommitted supply?
SB-SMP-0003Version 0.1.0MOVING CURRENTEvidence cutoff 2026-08-28EU-27 + United Kingdom + Norway + Switzerland + Serbia + Türkiye
A reported production baseline is visible; comparable capacity and available tonnes are not.
As of 2026-08-28
Comparable current AP capacityUNKNOWN
Current synthesis is directly evidenced at Toulouse and a June 2026 investigation reports a 5,000 t/y annual production baseline, but that output-like figure is not recast as current nameplate capacity.
→
Current merchant-oriented AP capacityUNKNOWN
ArianeGroup advertises AP products and logistics services, which establishes merchant orientation but not annual external capacity, uncommitted allocation or programme interchangeability.
→
Uncommitted qualified APUNKNOWN
The retained sources do not quantify current output, commitments, inventories, accepted alternative sources or allocatable customer-grade tonnage.
Capacity composition unavailableUNKNOWN
Comparable current annual AP capacity. Current synthesis is evidenced and a secondary source reports a 5,000 t/y annual-production baseline, but no retained source establishes a comparable current AP nameplate figure.
Inference boundary. Current synthesis is evidenced and a secondary source reports a 5,000 t/y annual-production baseline, but no retained source establishes a comparable current AP nameplate figure. The 5,000 t/y figure is secondary reporting of annual production, not independently observed output or confirmed capacity. The planned 3,000 t/y increment, historic 2012 observations, sodium-perchlorate consumption basis, destruction throughput and downstream propellant tonnage remain outside current capacity and available supply.01 · Material role
The strategic object is qualified AP, not undifferentiated perchlorate tonnage.
The useful chain runs through precursor continuity, synthesis, particle control, formulation and motor acceptance.
02 · SynthesisReaction + crystallisationControlled synthesis and crystal-size production at an authorised site.
03 · ConditioningGrinding + blendingParticle size, shape and distribution prepared for a qualified formulation.
04 · Qualified outputAP → composite propellant → motorMixing, casting, curing and programme-specific motor qualification.
Propulsion-grade AP
Ammonium perchlorate is the oxidiser in conventional composite solid propellants used in civil launchers and military rocket motors; particle size, distribution, purity and accepted source remain part of the usable material definition.
Adjacent but distinct states
Commodity perchlorate salts, laboratory AP, waste AP, destruction throughput and downstream propellant tonnage are excluded from current propulsion-grade AP production. Synthesis, grinding, blending, storage, formulation and motor qualification remain distinct industrial states.
Profile scopeEU-27 + United Kingdom + Norway + Switzerland + Serbia + Türkiye. Exclusions: Russia; Belarus; Distributors without evidenced production or conditioning; Downstream motor or propellant plants unless needed to establish the AP dependency; Waste-treatment throughput presented as production capacity; Historic capacity values presented as current capacity. This is a bounded public-source map, not a complete census. Absence from the profile does not establish absence of capability, imports or qualified alternatives.
02 · European production base
Current synthesis is evidenced at Toulouse; conditioning and storage are separate nodes.
The map preserves each industrial function and keeps all undisclosed current quantities null.
ACTIVE_MERCHANT
Active merchant-facing Current production or conditioning is evidenced and external sale or service is explicit; uncommitted volume is not implied.
ACTIVE_CAPTIVE
Active integrated or strategic Current capability is evidenced inside an integrated or sovereign chain; exclusive captive use is not implied.
CONVERSION
Conversion An existing industrial asset has a sourced conversion plan but accepted output is not yet evidenced.
PLANNED
Planned A sourced project or programme exists without evidenced commissioned output.
LEGACY_INACTIVE
Legacy or inactive Historic capability is retained for lineage but is excluded from the current footprint.

REPORTED
Capacity reading rule Current synthesis is evidenced and a secondary source reports a 5,000 t/y annual-production baseline, but no retained source establishes a comparable current AP nameplate figure. All current annual-capacity groups remain null/undisclosed. A June 2026 secondary report of 5,000 t/y annual production is retained as a claim rather than relabelled as nameplate. The reported 3,000 t/y planned increment and historic 2012 observations remain outside the current total.
03 · Market structure
Merchant orientation is visible, but allocation and qualified alternatives are not.
Product marketing, integrated programme use and uncommitted supply answer different questions.
Current merchant-oriented AP capacityUNKNOWN
ArianeGroup publishes a product specification, export-licensing support and transport services. The sources do not quantify external allocation or customer commitments.
Current integrated or strategic AP capacityUNKNOWN
The same industrial chain also supports Ariane and M51 applications and includes integrated conditioning and storage in Gironde; programme allocation is undisclosed.
Current strategic finding · INFERRED
The bounded current map identifies one directly evidenced propulsion-grade AP synthesis site at Toulouse and separate conditioning or storage infrastructure around Saint-Médard and Sainte-Hélène. A June 2026 investigation reports a 5,000 t/y annual-production baseline, but it is not independently confirmed as current output or nameplate and says nothing about allocation. The evidence supports a concentration signal, not a quantified shortage finding.
The producer search is bounded rather than exhaustive.
The strongest Europe-wide producer statement in the official source is rooted in historic evidence.
Product availability and internal programme use do not disclose allocatable tonnes.
Could reverse: Current authoritative evidence of additional qualified European AP synthesis
Could reverse: Current capacity and allocation records demonstrating diversified accepted headroom
Could reverse: Programme evidence showing rapid, low-friction substitution across motor formulations
Nearest disclosed intervention surfaceTwo intervention surfaces are visible but not commissioned in the retained evidence: a reported Toulouse annual-production rise from 5,000 to 8,000 t/y alongside an official construction permit, and a Sainte-Hélène proposal for two months of sodium-perchlorate decoupling stock based on 28 t/day consumption. Neither can yet be counted as accepted additional AP supply.
04 · Expansion pipeline
Toulouse has a reported 3,000 t/y expansion path and a separate upstream buffer project.
Permit existence, reported target capacity, commissioning and qualified output remain separate evidence states.

UNDISCLOSEDUNDISCLOSED
Not an AP sale
The project is an internal raw-material buffer and does not itself create merchant AP capacity.
REPORTED
Pipeline boundary A June 2026 investigation reports a Toulouse rise from approximately 5,000 to 8,000 t/y and an official April 2026 permit records new industrial surface, but neither source establishes commissioning. Separately, the 2024 Sainte-Hélène sodium-perchlorate filing is an upstream buffer, not AP nameplate.
05 · Dependencies & bottlenecks
Particle control and qualification sit between chemical tonnes and a usable motor grain.
Historic source qualification and current product specifications show why substitution cannot be reduced to formula identity.
REPORTED DEPENDENCY
Sodium-perchlorate continuity
ArianeGroup's 2024 filing describes sodium perchlorate as necessary to Toulouse AP production and proposes a two-month buffer; Arkema's current Jarrie profile separately identifies sodium perchlorate for Ariane rocket fuel.
The product sheet distinguishes crystallised and ground sizes, controlled particle shape and custom distributions; formula identity alone does not establish formulation interchangeability.
The Toulouse site operates under authorisation and Seveso upper-tier status, and an April 2026 permit records new industrial construction; neither source establishes commissioning or qualification lead time.
No European AP sufficiency scalar emittedThe retained evidence does not join current nameplate, actual output, imports, inventories, formulation compatibility, programme commitments and dated demand. One evidenced synthesis site is not itself proof of shortage, surplus or non-substitutability.
06 · Strategic assessment
The evidence supports a concentration finding, not a quantified shortage claim.
The next decision value comes from current capacity, allocation, accepted-source and transfer-time evidence.
V0.1 verdict · INFERRED
The bounded current map identifies one directly evidenced propulsion-grade AP synthesis site at Toulouse and separate conditioning or storage infrastructure around Saint-Médard and Sainte-Hélène. A June 2026 investigation reports a 5,000 t/y annual-production baseline, but it is not independently confirmed as current output or nameplate and says nothing about allocation. The evidence supports a concentration signal, not a quantified shortage finding.

Current strategic finding
The bounded current map identifies one directly evidenced propulsion-grade AP synthesis site at Toulouse and separate conditioning or storage infrastructure around Saint-Médard and Sainte-Hélène. A June 2026 investigation reports a 5,000 t/y annual-production baseline, but it is not independently confirmed as current output or nameplate and says nothing about allocation. The evidence supports a concentration signal, not a quantified shortage finding.
Two intervention surfaces are visible but not commissioned in the retained evidence: a reported Toulouse annual-production rise from 5,000 to 8,000 t/y alongside an official construction permit, and a Sainte-Hélène proposal for two months of sodium-perchlorate decoupling stock based on 28 t/day consumption. Neither can yet be counted as accepted additional AP supply.
Confidence HIGH ON PROJECT EXISTENCE LOW ON COMMISSIONING
No Europe-wide AP surplus, deficit, bottleneck quantity or twelve-month motor-output loss is emitted because current supply, imports, qualified interchangeability, inventories, commitments and dated demand are not joined.
AP substitution is not safely modelled as tonne-for-tonne chemistry. Current product evidence exposes particle-size and distribution choices, while ESA's historic Ariane account shows a new European AP source passing through motor qualification before it enabled dual procurement.
Confidence HIGH ON MECHANISM LOW ON CURRENT DURATION
Resolve construction and commissioning of the reported Toulouse 3,000 t/y increment and the Sainte-Hélène sodium-perchlorate store, including accepted output and usable inventory policy.
Decision value: Separates permitted or proposed interventions from twelve-month qualified supply.
Map AP source, particle distribution, conditioning route and qualification status by European motor family without publishing sensitive formulation detail.
Decision value: Identifies where a chemically available tonne is not a qualified tonne.
Can Toulouse's reported 5,000 t/y annual-production baseline be independently confirmed, and what are nameplate, current output and utilisation by particle distribution?
Would change: The current supply baseline and expansion headroom.
02
How much current output is committed to Ariane, M51, tactical propulsion and external customers?
Would change: The uncommitted merchant-supply finding.
03
Which non-European sources and AP grades are already qualified for which European motor families?
Would change: The concentration and substitution assessment.
04
Was the Sainte-Hélène sodium-perchlorate decoupling store commissioned and filled?
Would change: The upstream interruption-resilience finding.
05
Which sodium-perchlorate suppliers, transport routes and inventory policies support Toulouse?
Would change: The location and recoverability of the upstream constraint.
06
When will the permitted Toulouse expansion commission, and what part of the reported 3,000 t/y increment will become accepted output?
Would change: The expansion timeline, qualified increment and twelve-month intervention value.
07
What AP inventories exist at conditioning, propellant and motor sites, with what shelf-life and acceptance state?
Would change: The twelve-month disruption counterfactual.

The INERIS substance profile, updated in 2024, retains an economic-data statement that predecessor Herakles was the only European AP manufacturer and produced at Toulouse.
REPORTED · Scope: Historic Europe-wide producer statement retained by an official technical portal
Limitation: The underlying manufacturer evidence is from 2012–2013; it does not prove that no other producer exists in 2026.
The same INERIS profile reports historic Toulouse installation capacity above 3,500 t/y and production around 3,000 t/y in 2012, while also citing a separate 4,000 t/y industry estimate.
REPORTED · Scope: Historic Toulouse capacity and output evidence
Limitation: The values are old, differ in scope and are not current capacity; the profile excludes them from current headline signals.
The 2024 Sainte-Hélène filing says sodium perchlorate is necessary for Toulouse AP production and proposes a two-month decoupling stock based on consumption of 28 tonnes per day.
REPORTED · Scope: Reported upstream resilience project and planning basis
Limitation: The 28 t/day value is a sodium-perchlorate consumption assumption, not AP output, and the source does not establish commissioning.
ESA reported in 1995 that an Ariane 5 solid-booster engine developed with a European SNPE AP source passed a qualification test, enabling dual procurement for future launches.
REPORTED · Scope: Historic AP source-change qualification mechanism
Limitation: The event does not quantify present-day qualification time or prove the same process for every missile motor.
