Expromet and JOSCAR: trusted certification for aerospace and defence buyers

How our JOSCAR accreditation helps OEMs and Tier 1 suppliers streamline procurement, reduce risk, and gain supply chain confidence

Introduction

Expromet Technologies Group is a precision manufacturing group serving global OEMs, Tier 1s and Primes with a wide range of casting, machining and engineering solutions. Each of our three sister companies — Haworth Castings, Investacast, and Metaltech Precision — has achieved JOSCAR accreditation. Expromet is one of the few precision engineering groups with all operating companies JOSCAR-certified — offering buyers unrivalled flexibility and assurance. This means that buyers can engage with any part of the group knowing that supplier assurance is already in place and recognised by leading aerospace and defence organisations.

What is JOSCAR certification?

The Joint Supply Chain Accreditation Register (JOSCAR) is an accreditation system used by the aerospace, defence and security sectors to simplify supplier assurance. Managed by Hellios, JOSCAR provides a centralised database of pre-qualified suppliers. It is supported by some of the industry’s most prominent Primes and buyers, including BAE Systems, QinetiQ, Leonardo, and Rolls-Royce.

Why JOSCAR matters to aerospace and defence buyers

Procurement efficiency

For buyers, JOSCAR reduces the administrative effort involved in supplier approval. Instead of repeating the same checks with each organisation, suppliers complete a single, standardised qualification process. Buyers can then access this shared record to confirm compliance, reducing duplication and accelerating procurement decisions without compromising due diligence: enabling quicker project kick-offs without compliance delays.

Compliance assurance

The system ensures that suppliers meet industry requirements covering quality, business continuity, health and safety, cyber security and more. Buyers benefit from greater confidence that their supply chains are compliant with regulations and sector standards.

Risk management

JOSCAR reduces supply chain risk by ensuring suppliers are pre-screened and meet stringent criteria. This is particularly important in aerospace and defence, where reputational and operational risks are high.

Cost and time savings

Because checks are centralised, JOSCAR reduces the need for duplicate audits and questionnaires. For both buyers and suppliers, this lowers administrative cost and improves efficiency.

Renewal and ongoing commitment

JOSCAR certification is not a one-off exercise. Suppliers are required to renew their accreditation annually to remain on the register. This ensures that buyers can always rely on up-to-date information and continued compliance.In short, JOSCAR is not just an accreditation — it is a procurement tool that enables faster, more reliable and more compliant decision-making.

JOSCAR accreditation across the Expromet group

Each of Expromet’s operating companies is individually registered and accredited within the JOSCAR system. This means buyers can work directly with any of our businesses, confident that JOSCAR approval has already been secured.

This group-wide accreditation reflects Expromet’s commitment to quality and compliance across all metal forming processes:

Haworth Castings: specialists in aluminium sand and gravity die cast defence components.
Investacast: experts in investment casting, pressure die casting and forging for mission-critical aerospace applications.
Metaltech Precision: providers of high-precision CNC machining and fabrication, including sliding-head machining of small complex parts for performance-critical systems.

For buyers, this translates into simpler approvals, reduced risk, and confidence in sourcing from any Expromet company.
