Thomas G Limited Global Operations
Hong Kong HQ & European Liaison

Founded by CEO Thomas Goeminne, delivering European engineering rigor with real-time Asian factory access.

Our Heritage

From Hands-on Sourcing to a Digital Production Network

Fifteen years ago, Western companies faced persistent communication breakdowns, counterfeit certifications, and opaque subcontracting in overseas manufacturing. Thomas G Limited was established to offer an uncompromising alternative: direct on-ground engineering accountability, transparent factory audits, and reliable global fulfillment.

2010 — Founded in Hong Kong

Initiated supply chain operations, direct factory sourcing, and multi-lingual technical liaison for European brands.

2016 — Taiwan Precision & Tooling Expansion

Formed technical alliances in 5-axis CNC machining, micro-tolerances, aluminum die casting, and electronics integration.

2021 — Multi-Factory Ocean Freight Consolidation

Established cross-docking facilities to pack multiple suppliers into unified 20ft/40ft containers, saving up to 35% in logistics overhead.

2026+ — The Digital Production Powerhouse

Proprietary online PLM management, automated DFM checks, shopfloor MES production tracking, and secure milestone escrow.

Frequently Asked Questions

Clear, transparent answers on how we protect your project, funds, and intellectual property.

All files uploaded to TSG Limited are safeguarded under bilateral non-disclosure agreements enforceable in Hong Kong, the US, and Europe. Furthermore, when subcontracting specialized processes, we partition CAD components so no single factory holds the complete assembly files, preventing unauthorized cloning or market leakage.

Yes. Our multi-supplier consolidation hub is one of our flagship advantages. We cross-dock goods from Taiwan, Shenzhen, and Vietnam into our central consolidation warehouse, conduct final carton drop tests, pack optimized Full Container Loads (20GP / 40HQ), and issue a single unified Bill of Lading.

Under TSG’s escrow milestone contract, the manufacturing partner does not receive final payment until an ISO 2859-1 Level II Pass Certificate is generated. If a batch exceeds defect thresholds, the factory is contractually required to perform 100% screening and rework at their expense before re-inspection.

Because we operate across multiple production tiers, we support projects from rapid prototyping (1 – 50 units) to pilot production runs (500 units) and high-volume mass production (100,000+ units). Each process has optimal tooling thresholds which our DFM review highlights immediately.
