Product Overview
TOPSPOT is a functionally graded material (FGM) impact protection system combining silicon carbide ceramic strike face, gradient transition zone, and UHMWPE composite backing for superior threat defeat with optimized weight efficiency.
Technology Foundation: Hybrid composite FGM architecture delivers international standard 4569 Level 4 protection validated through independent testing at a major Turkish defence producer (Turkey) against 14.5mm B32 API at 911 m/s impact velocity.
Export Status: ITAR-free UK origin with ML13.a classification. Export to 37 OGEL nations permitted; SIEL required for non-OGEL destinations. Full compliance with UK Export Control Act 2002.

Export Control Notice
UK Export Control Classification: TOPSPOT impact protection systems are classified under ML13.a (Protectioned or protective equipment and components) of the UK Strategic Export Control Lists.
Export Requirements:
- OGEL Nations: Export to 37 specified nations permitted under Open General Export Licence (OGEL) without individual licence application
- Non-OGEL Nations: Standard Individual Export Licence (SIEL) required from UK Export Control Joint Unit (ECJU)
- Processing Time: SIEL applications typically 20 working days (OGEL: immediate)
- End-Use Certification: Customer must provide end-use documentation for all exports
ITAR-Free Advantage: UK origin eliminates U.S. State Department DDTC approval requirement, significantly reducing export timeline and administrative burden compared to ITAR-controlled alternatives.
Full compliance with UK Export Control Act 2002 and UK Export Control Order 2008. Belvyon provides export control support and documentation for all international orders.
