A Case of Hidden Cost Drivers
Two companies built nearly identical smart access control devices. Both used the same components, sourced from the same region, and targeted the same U.S. market. On paper, the designs were indistinguishable.
But when the shipments arrived at U.S. customs, one company was charged a 25% import duty. The other paid nothing.
The difference? Country of Origin.
This isn’t a rare edge case. It’s a common issue for electronics companies that focus solely on BOM and assembly cost—without factoring in how COO and landed cost affect total cost per unit.
The Same BOM, Two Import Paths
Company A assembled its entire product in mainland China. That included firmware flashing, final assembly, testing, and packaging—all handled in the same location.
Company B followed the same design and sourced from the same suppliers. However, they changed one critical part of the process.
Instead of completing everything in China, they shipped the assembled PCBAs to Taiwan. There, they handled the firmware installation, calibration, and final packaging before exporting to the U.S.
Because the final transformation occurred in Taiwan, customs recognized Taiwan as the Country of Origin for Company B. That shipment entered tariff-free. Company A’s product, assembled entirely in China, fell under Section 301 duties, adding 25% to the landed cost.
The designs were the same. But their import costs were not.
Why Country of Origin Isn’t Where Your Parts Come From
Many assume COO is based on the source of most components. But that’s not how customs evaluates it. The real test is whether the product undergoes substantial transformation—a change in name, character, or use—before export.
As outlined by U.S. Trade regulations, transformation can include steps like firmware loading, sensor calibration, and final testing. But simply moving boxes through a warehouse or adding a label doesn’t qualify.
Companies that misdeclare COO, intentionally or otherwise, may be flagged for “origin washing”, leading to fines, shipment delays, or audits.
BOM Savings Won’t Save You Here
Company A had worked hard to reduce its Bill of Materials. But once Section 301 tariffs applied, the product’s landed cost increased by more than 15%. The extra duties erased the savings achieved through careful sourcing.

By contrast, Company B paid slightly more for logistics and regional assembly, but protected their margins by avoiding unnecessary tariffs.
This isn’t just about compliance—it’s about maintaining pricing power and margin predictability at scale.
How to Get COO Right from the Start
The solution isn’t just about moving factories. It’s about understanding which processes determine COO and designing your production flow accordingly.
To reduce risk and cost:
- Identify which transformation steps could shift COO (firmware loading, final testing, etc.)
- Consider relocating those steps to countries with better trade access, such as Taiwan, Colombia, or Mexico
- Align your design-for-manufacturing (DFM) choices with regional compliance strategies
- Maintain clear documentation of assembly and transformation steps to support COO claims

Final Thought
These two companies made the same product, with the same parts and the same specs. But one lost margin and time due to a preventable mistake in COO handling.
In today’s trade environment, Country of Origin is a financial variable—not just a label.
Getting it wrong will cost you.
Getting it right gives you an edge.
At Titoma, we help clients design electronics with the full picture in mind—including COO, testing location, and landed cost. By coordinating design and manufacturing across Taiwan, Colombia, and China, we make it easier to optimize both cost and compliance from day one.
