FTZ Production Activity: Four Key 2026 Decisions

FTZ production activity can create meaningful duty-management opportunities, but authority is never automatic or unlimited. The 2026 outcomes involving Heidtman Tubular Products, Hypertherm, Turbocam, and Super Micro demonstrate why manufacturers must align proposed inputs, finished products, tariff exposure, and operational controls before relying on Foreign-Trade Zone benefits.

What the Four FTZ Production Outcomes Signal

FTZ production authority is highly specific to the company, location, inputs, finished products, and activity presented to the Foreign-Trade Zones Board. Authorization for one production model does not establish blanket permission for other merchandise or processes, even when they operate within the same activated zone or subzone.

Heidtman Advances a Steel Production Proposal

Heidtman Tubular Products, LLC notified proposed production of steel row tubes, steel tubes, and steel brackets at Subzone 70AF in Erie, Michigan. The proposed foreign-status inputs include flat-rolled steel coils and zinc-coated flat-rolled steel coils. Both the inputs and identified finished products generally carry duty-free ordinary tariff rates, but that does not eliminate the need for a complete tariff analysis.

Certain steel inputs may remain subject to Section 232 duties depending on origin and other applicable conditions. Merchandise subject to those duties generally must be admitted in privileged foreign status. That status preserves the tariff classification and duty treatment applicable at admission, rather than allowing the finished product's classification to determine the duty outcome.

The Heidtman notice is scheduled for publication on November 5, 2026. The 40-day comment period produces an expected December 15, 2026 deadline. Interested manufacturers, suppliers, and other affected parties should confirm the official deadline and submit substantive comments before it closes.

Authorization Can Be Limited, Withheld, or Withdrawn

Hypertherm received limited one-year authority for plasma cutting equipment production at Subzone 81H in Hanover and Lebanon, New Hampshire. Precision-cut hafnium wire was excluded as a foreign-status component pending further review.

Turbocam's proposed turbine system components activity in Ladson, South Carolina, was not authorized because further review was warranted. Pursuing the activity would generally require a production authority application. Super Micro Computer, meanwhile, withdrew its proposed high-performance computing systems notification for FTZ 18 facilities in California. Together, these outcomes illustrate that notification can lead to full authorization, conditional authority, additional review, or no further action.

Operational Controls Required After an FTZ Decision

An authorization is the beginning of the compliance process, not the end. FTZ operators and manufacturers generally must ensure that actual production remains within the scope of the approved activity. That requires controls connecting purchasing, admissions, inventory records, bills of material, production processes, and withdrawals into U.S. commerce.

Match Every Input and Output to the Approved Scope

A manufacturer should maintain an authorization matrix that identifies each approved foreign-status material, relevant tariff classification, finished product, production location, and applicable restriction. Under the FTZ production framework, authorized activity generally must match the specific materials and products reviewed by the Board.

This control becomes especially important when product engineering or sourcing teams introduce substitute materials. A new grade of steel, precision component, coating, electronic module, or supplier-origin combination may affect the tariff analysis even if the commercial description appears similar. The compliance team should review such changes before the merchandise is admitted or used in production.

Hypertherm's limited authorization provides a clear example. The company may conduct the authorized plasma cutting equipment activity, but precision-cut hafnium wire cannot simply be treated as another approved foreign-status component. The exception must be reflected in admission procedures, inventory controls, bills of material, and internal instructions.

Preserve the Correct Status for Section 232 Merchandise

Ordinary customs duty rates are only one part of the FTZ calculation. Section 232 duties may apply independently to covered steel or aluminum products. For affected steel inputs, privileged foreign status generally locks in the applicable classification and duty treatment at the time of admission under 19 CFR 146.41.

Operators should therefore validate origin, product scope, exclusion eligibility, and status designation before admission. Incorrect status treatment can undermine the expected FTZ benefit and create exposure during entry review, reconciliation, or audit. Broker instructions should clearly distinguish ordinary duty treatment from additional tariffs and other trade remedies.

Building an Integrated Duty-Management Strategy

The growing use of FTZ production procedures reflects the pressure that tariffs place on manufacturing supply chains. However, an FTZ should not be evaluated as a stand-alone customs program. Companies generally achieve better results when FTZ operations are considered alongside duty drawback, bonded movement, sourcing decisions, tariff engineering, and export planning.

Duty-Free Rates Do Not End the Analysis

The Heidtman proposal illustrates why a zero ordinary duty rate can still require significant compliance work. The listed steel coils and finished products may be duty-free under the general tariff schedule, yet Section 232 treatment can materially alter the financial result. Similar issues can arise from antidumping and countervailing duty exposure, country-specific tariffs, or future changes in trade policy.

Trade directors should model multiple scenarios, including domestic consumption, exportation, scrap, destruction, rejected materials, and changes in supplier origin. The analysis should also account for the administrative cost of maintaining FTZ status controls and the possibility that a requested input or process will be excluded from authorization.

Corrections involving power plant facilities in FTZ 252 and FTZ 155 reinforce the importance of accurate rate data. The corrected notices added duty rates of 2.5 percent and 2 percent, respectively. Even relatively modest rates can become material when applied to capital-intensive energy projects with high import values.

FTZ Procedures and Drawback Serve Different Transactions

FTZ procedures generally manage duty treatment before merchandise formally enters U.S. customs territory for consumption. Duty drawback generally recovers eligible duties, taxes, and fees that were already paid when qualifying merchandise is later exported or destroyed.

A company should not assume that operating in an FTZ automatically creates a refund for past imports. Conversely, merchandise outside an FTZ may still qualify for drawback when the statutory and documentary requirements are satisfied. An integrated review can identify which transaction flows are better suited to FTZ treatment, drawback, or another customs strategy without treating the programs as interchangeable.

Frequently Asked Questions

What Is FTZ Production Activity?

FTZ production activity generally involves substantial transformation, assembly, or processing of foreign-status merchandise within an activated Foreign-Trade Zone or subzone. A manufacturer typically must obtain production authority covering the relevant inputs, finished products, facilities, and operations before conducting the proposed activity under FTZ procedures.

Does Filing a Production Notification Guarantee Authorization?

No. The Board may authorize the proposed activity, limit the authorization, exclude specific foreign-status components, determine that further review is required, or take no further action after a withdrawal. A company should avoid building financial projections around an assumed approval until the scope and conditions of the final decision are understood.

What Does Privileged Foreign Status Mean for Steel Inputs?

Privileged foreign status generally preserves the tariff classification and duty rate applicable to foreign merchandise when it is admitted to the zone. For steel subject to Section 232 duties, this status can prevent the processing operation from changing the applicable duty treatment when the finished merchandise enters U.S. commerce.

Can an FTZ Operator Use Materials Not Listed in an Authorization?

Not automatically. Production authority is generally limited to the inputs, products, locations, and activity reviewed by the Board. New materials or materially different operations should undergo compliance review. Depending on the circumstances, the company may need a new notification, a production authority application, or another form of approval before proceeding.

How Is Duty Drawback Different From FTZ Treatment?

FTZ procedures generally defer, reduce, or eliminate certain duties based on how merchandise is admitted, processed, entered, or exported. Duty drawback generally refunds eligible duties already paid on imported merchandise associated with qualifying exports or destruction. The programs can support the same broader duty-management strategy, but they apply through different legal and operational mechanisms.

How Stable Software Can Help

Customs brokers can help importer clients evaluate duty recovery opportunities that remain separate from FTZ admission and production authority. DrawbackAI is Stable Software's flat-license duty drawback software for U.S. customs brokers. Brokers can white-label the software for importer clients and file drawback claims under their own filer code.

Stable Software charges a flat software license and never takes a percentage of the refund. This structure allows brokers to retain control of the client relationship and filing process while offering duty drawback as a complementary option for eligible duties associated with exported or destroyed merchandise. Brokers reviewing FTZ supply chains can consider whether drawback may address qualifying transactions outside the zone or duties paid before an FTZ strategy was implemented.
