How an FTZ Builds More Flexibility Into Pharmaceutical Inventory Strategy

Pharmaceutical companies importing into the U.S. must decide when to bring inventory into the country, how much to commit to domestic demand and when to pay applicable duties. Those decisions become more difficult when demand forecasts, transportation schedules and trade conditions are changing.

Foreign-trade zones (FTZs) allow companies to separate some of those commitments. Eligible imported inventory can be held in a zone before entering U.S. commerce, with applicable duties generally payable when products are withdrawn for domestic consumption. Goods directly re-exported from the zone generally avoid U.S. import duties.

This creates an opportunity to complete international transportation while preserving options over the inventory’s release and destination.

The Case for Earlier U.S. Arrival

Positioning inventory domestically can support product launches, seasonal demand and preparations for transportation interruptions. Having stock already in the country removes the need to wait for a new international shipment when that inventory is required, although customs, regulatory and quality-release requirements still apply.

An FTZ adds a financial dimension to that positioning strategy. Companies can hold eligible products closer to U.S. demand without immediately paying applicable duties on the full imported allocation. The benefit is duty deferral rather than an automatic exemption from tariffs.

The pharmaceutical industry has also used FTZs to prepare inventory ahead of regulatory authorization. A 2023 U.S. International Trade Commission study documented Pfizer’s use of an FTZ to store its vaccine and other COVID-19 pharmaceuticals pending FDA emergency use authorization.¹ Pfizer reported saving days of transit time through the arrangement, supporting rapid distribution after authorization.

The example illustrates how the customs framework can support operational readiness: international movement takes place before authorization, leaving fewer transportation steps once distribution is permitted.

Why Keep Market Allocation Open?

Bringing inventory into an FTZ does not necessarily commit it to the U.S. market. Eligible foreign merchandise can remain in the zone while companies determine what quantities will enter domestic commerce and what may be re-exported.

That distinction matters for companies serving multiple markets. Rather than entering an entire shipment for U.S. consumption on arrival, they can make release decisions closer to when demand becomes clear.

The financial significance of export treatment is documented in the USITC study, which estimated hundreds of millions of dollars in export-related duty savings in 2021 for pharmaceutical firms producing in U.S. FTZs, with some firms reinvesting those savings in expanding and modernizing their operations.¹ These findings include manufacturing benefits beyond those available through storage alone, but demonstrate the program’s established role in pharmaceutical operating economics.

Case Study: Frontier’s Wilmington Facility

Frontier Scientific Solutions’ Wilmington, North Carolina facility provides an example of how FTZ capabilities can be incorporated into pharmaceutical storage and distribution.

The facility combines its FTZ capabilities with temperature-controlled storage, documented handling, inventory management and coordinated distribution. Eligible imported products can be held before entering U.S. commerce, allowing companies to plan domestic releases or re-exports while maintaining the required storage conditions.

“For pharmaceutical companies, the value of an FTZ goes well beyond when duties are paid,” said Michelle D’Angelo, chief commercial officer at Frontier Scientific Solutions, in a statement to Pharmaceutical Commerce.² “It gives supply chain teams more control over inventory that is already located in the U.S. At our Wilmington facility, companies can position product closer to U.S. demand while maintaining flexibility over when and where that inventory is ultimately distributed.”

The Wilmington approach brings the customs and physical handling requirements into the same operation. FTZ procedures determine the treatment of eligible inventory, while storage controls, inventory records and distribution arrangements support its eventual release.

For a company importing ahead of anticipated demand, that means product can complete its international journey without the full allocation immediately entering domestic commerce. Quantities can subsequently be released for U.S. distribution or directly re-exported, subject to the applicable requirements.

How Do FTZs Assist Disruption Planning?

The same approach can support continuity planning. Holding a defined amount of inventory domestically reduces reliance on overseas replenishment if normal shipping patterns are interrupted. An FTZ adds flexibility around duty payment while eligible inventory remains in storage.

Its usefulness depends on the products involved, their duty exposure, expected storage period and destination markets. For temperature-sensitive pharmaceuticals, those considerations must also align with shelf life, storage conditions and release requirements.

An FTZ therefore forms one part of an inventory strategy. Its practical value comes from allowing companies to bring products closer to demand while keeping certain financial and allocation decisions open until more information is available.
