OUR TECHNOLOGY
DRAWBACK INTELLIGENCE: BUILT ON EXPERTISE, ENHANCED BY AI™
The People and Technology Behind Every Claim.
At Charter, our people lead and our technology follows their expertise. Hamilton, our proprietary drawback platform, was built by our own team of drawback experts, data scientists, and programmers. It is operated, validated, and continuously improved by those same people every day.

OUR PROPRIETARY PLATFORM
Meet Hamilton — custom built for drawback, by drawback experts.
Hamilton is a custom-developed, proprietary drawback program built from the ground up to deliver the most accurate and substantial claims possible for Charter’s clients. Every feature, every workflow, and every output reflects decades of drawback expertise translated directly into technology.
Hamilton was built to grow. As drawback regulations evolve and our clients’ needs change, Hamilton adapts alongside them. It is a dynamic platform designed to remain as current as the industry it serves.

THE TECHNOLOGY TEAM BEHIND THE PLATFORM
Every role on this team starts from the same foundation: duty drawback expertise.
Our data scientists, programmers, and integration specialists are not technologists who learned drawback – they are drawback practitioners who built the technology. This team includes people with over 30 years in the field and people who helped write the regulations themselves.
Our dedicated data integrations team works directly alongside each client to determine the most efficient method of data delivery and retrieval for their specific operation. Every engagement starts with understanding your business first, then building the process around it.
- Data Scientists: Analytics that maximize every claim filed on your behalf.
- Programmers: Proprietary systems built and owned entirely in-house.
- Integration Team: Seamless, systemic data delivery tailored to your operation.
Building an effective technology product for duty drawback requires more than engineering talent. It requires knowing drawback itself, the regulations, the edge cases, the filing nuances, that only come from years of working in the field. Hamilton was built by people who have spent their careers in this industry, and that depth of knowledge is embedded in everything it does. That is a foundation that has to be earned.
How We Work
A systemic, validated approach to every claim.
Charter’s people make every decision. The tools we have built make those decisions faster, sharper, and more defensible. Hamilton is a precision instrument, operated entirely by our team, to support the expert judgment that Charter’s clients have always relied on.
Here is exactly how we approach every claim:
- Document Processing — Hamilton processes large volumes of trade documents systematically, reducing manual data entry and the errors that come with it. Our team configures and validates every document type it handles.
- Data Validation and Integrity Checks — Every data set is run through rigorous validation protocol checks before any claim is filed, surfacing the details our experts need to make the strongest possible decision. Every detail clears our compliance standards before moving forward.
- Analytics and Claim Optimization — Validated data is analyzed to identify the maximum defensible return available on every claim. Our people review, confirm, and make the final call.
- Tracking and Transparency — Every claim is tracked from the moment raw data is received through final filing, creating a complete audit trail with compliance backing at every step. Charter's team and our clients have full transparency from start to finish.
How it works
From raw data to filed claim, step by step.
Charter’s process is built around one goal: filing the largest, most defensible return on behalf of every client. That requires discipline, validation, and transparency at every step.

Every piece of technology Charter builds exists to make our people more effective. Our customs attorneys, licensed brokers, compliance specialists, and data experts are the foundation of everything Hamilton does. They set the standards. They validate the outputs. They are accountable to every client, on every claim.
Hamilton makes Charter faster. Our people make Charter better. And that combination is something truly special.
