The reality
International trade is operationally brutal
Your team should be focused on customers and growth — not drowning in admin.
Each one is a financial landmine. Miss one on a Chinese steel shipment and you're looking at 300%+ duties. No tool helps you check — until now.
Each one requires 30-50 data fields keyed manually from shipping documents. At a 2-5% error rate, that's millions of wrong entries reaching CBP.
The customs broker license exam pass rate. There aren't enough brokers to go around — and the ones you have are spending their time on data entry, not compliance.

Frequently Asked Questions
Everything you need to know about Tandom and how it works.
Tandom is a set of tools built specifically for freight forwarders and customs brokers. Each tool handles a different part of trade compliance — duty calculation, AD/CVD intelligence, HTS classification, and entry preparation. Use one tool or use them all. They work standalone and get better together.
Absolutely. Every Tandom tool works independently. Most customers start with the free duty calculator, then add AD/CVD intelligence or HTS classification as they see the value.
We're currently working with our first pilot customers. During this phase, we work closely with each team to make sure the tools deliver value before we formalize pricing. Book a demo to discuss what makes sense for your operation.
Tandom is API-first and designed to connect to the systems you already use — TMS platforms, ERPs, email, carrier portals, and customs software. We also offer web apps that work without any integration, and an Excel plugin for teams that live in spreadsheets.
The calculator covers the full US tariff stack including MFN rates, Section 301, Section 232, IEEPA, and case-level AD/CVD with Federal Register citations. Every rate is verified against primary sources, and 42 monitoring agents keep the data current. It's the same engine we provide through our API.
A 20-minute call where we learn about your operation, show you the tools most relevant to your pain points, and discuss whether a pilot makes sense. No pressure, no commitment — just a conversation about what's slowing your team down.
No. Tandom is designed to work alongside your existing tools, not replace them. The web apps require zero integration. The APIs and Excel plugin embed directly into your current workflow. No migration required.
