War, Tariffs, and Trade Disruption: Why FTZs Are Becoming a Supply Chain Lifeline

By Simran Sethi, Senior Industry Solutions Consultant, Global Trade Intelligence, Descartes

The last few years have changed the way many importers think about global trade. Previously predictable costs can now change overnight. Policy announcements, geopolitical events, trade lane disruptions, sanctions programs, forced labor enforcement and tariff volatility have all made it more difficult to forecast landed costs and plan inventory with confidence.

With that in mind, more and more companies are looking at Foreign Trade Zones (FTZs) to manage duty costs and create more flexibility when sourcing. In an environment where trade policy can change faster than business plans, the ability to delay key decisions can be just as valuable as the ability to reduce costs.

As trade compliance, logistics, and finance leaders looking for ways to enhance operational resilience, FTZs are attracting renewed attention across a wide range of industries.

When tariffs increase or inventory sits in storage longer than expected, companies often end up paying duties long before products are sold and revenue is generated. FTZs help by allowing businesses to defer duty payments until products enter U.S. commerce. For many importers, that means greater control over cash flow and more flexibility when market conditions or customer demand change. This flexibility allows companies to make inventory and sourcing decisions with more time and better information.

• FTZs can help companies improve cash flow by delaying duty payments until goods enter U.S. commerce and, in some cases, eliminating duty obligations altogether on merchandise that is ultimately exported.
• As tariffs, sanctions, and supply chain disruptions continue to reshape global trade, many companies are evaluating FTZs as a way to build greater flexibility into their operations.
• Organizations use FTZs to gain more control over inventory, support export activity, and better manage merchandise subject to customs oversight.
• Effective FTZ software provides the visibility and recordkeeping needed to manage inventory movements, support customs reporting requirements, and maintain confidence during internal reviews and external audits.
• The most successful FTZ programs extend beyond the trade compliance function. They typically involve close coordination among finance, logistics, operations, warehouse management, and technology teams to ensure both compliance and operational value.

A few years ago, most FTZ conversations focused primarily on cost savings. Companies wanted to understand how much duty could be deferred, reduced, or avoided. Many organizations are now asking how they can respond when, for example, tariffs change again, when inventory remains in storage longer than expected, or when sourcing strategies need to be adjusted with little notice. As trade conditions become less predictable, duty exposure, inventory management, and the timing of costs have become strategic business considerations rather than customs concerns.

These concerns have become more pressing as companies navigate an increasingly complex mix of trade measures. Section 301 tariffs, Section 232 tariffs, antidumping and countervailing duties, sanctions programs, forced labor requirements, and other trade restrictions have made duty planning far more challenging. At the same time, guidance affecting FTZ operations has reinforced the importance of understanding how merchandise is treated when admitted, particularly when privileged foreign status requirements apply. For many organizations, the challenge has become maintaining enough flexibility to adapt when trade requirements change.

Companies are increasingly evaluating FTZs through a broader lens. While inverted tariff opportunities remain important for some businesses, many organizations are focused on the wider benefits FTZs can provide. Duty deferral, export advantages, weekly entry savings, inventory visibility, and stronger oversight of customs-controlled merchandise all contribute to greater flexibility when business conditions change.

The main reason companies used to explore FTZs was to defer duty payments until products entered the U.S. market. Instead of paying duties when goods cross the border, with an FTZ, importers can hold inventory in the zone and pay only when products are sold in the domestic market.

Now, companies are investigating additional benefits. For instance, when goods enter into an FTZ and are exported instead of entering the domestic market, duties may be avoided. This can be especially beneficial for manufacturers and distributors relying on a single U.S. facility for both domestic and international customers. FTZ users can also consolidate withdrawals through weekly entry instead of filing each entry separately.

Beyond simple duty savings, an FTZ can also support postponement, kitting, light assembly, repair, quality inspection, relabeling, and redistribution. For many organizations, the operational flexibility provided by an FTZ can be just as valuable as the financial benefits.

As usage grows, FTZ operators often reach the point where manual processes are no longer sustainable. Companies are expected to maintain accurate records, know the status of their inventory, follow secure procedures, and track merchandise from admission through withdrawal, transfer, destruction, or export. It’s a level of control that’s difficult to manage with spreadsheets, disconnected warehouse systems, or manual processes, especially as inventory volumes grow.

For many compliance leaders, the biggest value of FTZ software is the ability to demonstrate exactly what happened. Companies need to show which goods entered the FTZ, what status they held, whether they were manufactured or manipulated, when they left the zone, what duty treatment applied, and whether system records align with physical inventory. Without reliable data, answering those questions can quickly become difficult. FTZ software helps bring this information into a single system of record, reducing the risk of inconsistencies while supporting reporting, exception management, and compliance requirements. Better visibility helps teams manage inventory, duty exposure, and day-to-day supply chain decisions with greater confidence.

Companies of many sizes use FTZ programs when the financial impact supports the investment. The starting point is usually a straightforward analysis of import volumes, duty costs, inventory levels, export activity, and merchandise processing fees. The goal is to determine whether the operational and financial benefits outweigh the cost of implementation and ongoing administration.

Once a company decides to move forward, the process typically involves coordination with an FTZ grantee, the Foreign Trade Zones Board, U.S. Customs and Border Protection (CBP), and technology providers. Depending on needs, a business may join an existing zone, pursue subzone designation, or seek production authority if manufacturing activities will take place within the FTZ.

However, obtaining approval is only one part of the process. CBP expects FTZ operators to maintain accurate inventory records, document merchandise movements, reconcile inventory balances, and demonstrate effective internal controls. As a result, successful FTZ projects typically involve multiple teams, including trade compliance, finance, logistics, warehouse operations, IT, and executive leadership.  Organizations that address these operational requirements early in the implementation process are often better positioned to realize the benefits of an FTZ program and avoid compliance or inventory management challenges later.

Tariff volatility affects everyday decisions across compliance, finance, logistics, and operations. A shipment may carry costs that were not part of the original forecast, or inventory may sit in a warehouse longer than expected.

This is where the timing benefit of an FTZ becomes important. Inventory can be admitted into the zone while the business determines whether products will be sold domestically, exported, assembled, or redistributed. When trade policy changes, having that additional time to decide can make a meaningful difference.

Modern FTZ software helps compliance, operations, and finance teams work from the same set of data, creating greater transparency across the organization. It reduces manual effort while providing the visibility needed to support audits, reporting requirements, and day-to-day decision making.

FTZs can give organizations more options when conditions change. For companies managing complex import programs, an FTZ supported by strong inventory controls and reliable software can provide the flexibility needed to make better decisions about inventory, duty exposure, and cash flow when uncertainty becomes the norm rather than the exception.
