Our History

NAT Cargo Enterprise Ltd was founded at Unit B & C, Ladfordfields Industrial Estate, Seighford, Stafford (ST18 9QE) – a strategic base from which we now deliver AUS40, EFFINOX, and DEF SOLUTIONS to over 200 ports across six continents.

World Experts

We are not just a supplier. We are a technical partner – from the first fill of a new-build SCR system to the 500th just-in-time delivery at a congested global port.

Local Knowledge

NAT Cargo Enterprise Ltd delivers to over 200 ports across six continents. Every delivery is backed by local agents, customs expertise, and real-time vessel tracking.

Nat Cargo Enterprise Ltd

Three Services. Nine Processes. One Standard.

At NAT Cargo Enterprise Ltd, every delivery of AUS40, EFFINOX-certified reagents, or DEF SOLUTIONS follows a disciplined workflow – from temperature-controlled storage to on-vessel verification. Below, we break down the key processes behind each service, so you can see exactly how we deliver certainty, not just chemicals.

Climate-Controlled Warehousing

Before any AUS40 leaves our Stafford headquarters, it rests in our temperature-controlled facility. Maintained strictly between 5°C and 25°C, every ISO tank is monitored 24/7 to prevent freezing or degradation.

Pre-Delivery Catalyst Verification

EFFINOX-certified reagents meet stricter purity tolerances than standard AUS40. Before any EFFINOX batch leaves our facility, we verify compatibility with leading SCR catalyst manufacturers – including MAN, Wärtsilä, and WinGD.

Depot & Facility Supply

For truck fleets, bus depots, and industrial facilities, we supply DEF Solutions in bulk – delivered directly to your storage tanks. Our dedicated dispensing systems ensure clean, contamination-free transfer every time.

FAQ

Got questions? We've got answers.

Here are answers to the most common questions about AUS40, EFFINOX, and DEF SOLUTIONS. Need more? Contact our technical team – we’re happy to help.

AUS40 contains 40% high-purity urea, while standard DEF (AdBlue) contains 32.5%. AUS40 is specifically formulated for marine Selective Catalytic Reduction (SCR) systems on ocean-going vessels, offering higher efficiency for larger engines. DEF (ISO 22241) is designed for road vehicles, auxiliary engines, and off-road machinery. Both are high-purity products, but they are not interchangeable. NAT Cargo supplies both – so you get the right product for your application, every time.
