Recent changes to U.S. tariffs are reshaping the landscape of cross-border shipping, impacting both the cost and compliance requirements for businesses involved in international trade. We’re monitoring these developments closely to understand how they affect duties, de minimis thresholds, and broader logistics. For the most up-to-date and official information, we recommend referring to the White House’s fact sheet here.
In this blog, we’ll break down the fundamentals of tariffs and duties, their role in cross-border shipping, and the challenges businesses must navigate in an evolving trade landscape.
Shipping internationally—even between the U.S. and Canada—comes with its own unique hurdles. Terms like “tariffs,” “duties,” and “de minimis thresholds” can be confusing, but understanding them is critical for managing costs and ensuring smooth delivery. We’ll break down these core concepts so you can ship across borders with greater confidence.
Tariffs are government-imposed fees on imported goods from specific countries, often applied for a set period. Unlike duties, which are typically fixed and based on the product’s value and classification, tariffs are strategic tools used to influence trade behavior or protect domestic industries. Because they can be introduced or changed at any time, they add a layer of uncertainty to international shipping.
Tariffs influence everything from consumer prices to supply chain planning, making them a central issue in global commerce.
The term de minimis refers to a minimum value threshold under which import duties and tariffs are waived. If your shipment’s declared value falls below this threshold, your customer typically won’t owe additional import charges. This is especially beneficial for companies shipping smaller, lower-value goods—whether you’re a small apparel brand or a global retailer.
It’s important to remember that de minimis values aren’t universal. Some countries have generous thresholds, while others set them low—or don’t offer them at all. That’s why it’s essential to research the import rules of each destination country before shipping there.
These terms are often confused, but they refer to different types of charges:
While both are taxes, understanding the difference helps ensure accurate pricing and smoother communication with customers.
