What Toll and Contract Manufacturing Means at Synthite
Synthite provides the manufacturing, technical expertise and regulatory framework.
The customer retains ownership of the formulation.
No Capital Investment
Access industrial-scale reactor capacity without the cost or complexity of owning and operating a regulated chemical manufacturing site.
Customer IP & Confidentiality
Customers retain complete ownership of their formulation and finished product. No proprietary information is shared beyond what’s operationally necessary, and full confidentiality is maintained throughout.
UK Manufacture & Logistics
Manufacturing and dispatch from a single site in Mold, North Wales, via Synthite’s own ADR-certified tanker fleet or as packed goods, reducing lead times and supply chain risk.
Hazardous Chemical Capability
COMAH upper-tier designation reflects the ability to safely handle hazardous and reactive chemistry.
Supported Chemistries, Blending and Processes
Synthite’s hazardous chemical manufacturing experience, specialist process personnel and reactor infrastructure make it a practical partner for many chemistries.
A lab-scale pilot plant mirroring full-scale reactor systems allows customers to develop and validate processes before committing to industrial production, reducing development risk and shortening the path to full-scale manufacture.
Facilities and Processing Capacity
Synthite’s toll manufacturing capability is built on industrial-scale reactor assets, controlled storage infrastructure and a lab-scale pilot plant.
All assets are operated under ISO 9001 and ISO 14001 certified management systems at a COMAH upper-tier regulated site.

Active Toll Manufacturing Operations
Synthite holds long-term toll manufacturing contracts with multinational companies. Active areas of established capability are oilfield chemicals and animal feed additives.
Toll Manufacture of Oilfield Chemicals Including H₂S Scavengers
Synthite undertakes toll manufacture of hydrogen sulphide scavengers and other oilfield chemicals on behalf of third-party customers. This activity is operationally and commercially distinct from Synthite’s own Syncide® product range. Customers retain full ownership of their formulations and intellectual property.
This capability is supported by Synthite’s backward integration into formaldehyde, the key raw material for triazine-based scavengers, providing a level of raw material security and quality assurance that many toll manufacturers cannot offer.
Toll manufacturing in this area is supported by:
- Controlled handling of hazardous and reactive chemistries
- Experience with amine-based and non-amine systems
- Operation within a regulated manufacturing environment
- Defined process controls supporting consistent batch quality at industrial scale
- In-house logistics for finished product dispatch
FEMAS Certified Toll Manufacture of Animal Feed Additives
Synthite undertakes toll manufacture of liquid animal feed additives on behalf of third-party customers, including acid blend formulations used in gut health and feed hygiene applications. Customers retain full ownership of their formulations and intellectual property throughout the manufacturing process.
This capability is supported by FEMAS certification, providing the quality and compliance framework required for manufacture and transport into regulated animal feed markets. FEMAS-certified transport ensures compliant supply chain handling from production through to delivery at the customer’s facility or end market.
Toll manufacturing in this area is supported by:
- UK-based manufacture within a regulated production environment
- FEMAS-compliant manufacture and FEMAS-certified transport
- Controlled handling of acidic and aqueous feed-related formulations
- Defined process controls supporting batch consistency and full traceability
- ISO 9001 and ISO 14001 management systems throughout
