FTZ Production Decisions: What Six Rulings Mean

FTZ production authority can deliver meaningful customs benefits, but authorization is neither automatic nor always permanent. Six decisions involving Tesla, Baker Hughes, Coroplast, StandardAero, Stadler, and AuroraTe illustrate how authorization scope, time limits, and further review can reshape a manufacturer’s duty strategy.

Six Decisions Show Different FTZ Authorization Outcomes

The Foreign-Trade Zones Board reached six production decisions on October 28, 2026, spanning battery storage, oilfield equipment, pressure-sensitive tapes, aircraft engines, passenger rail equipment, and galvanized steel pipe. Four production activities were authorized, although two approvals were limited by time. Two activities were not authorized because the Board determined that further review was warranted.

Four Manufacturers Received Production Authority

Tesla received limited authorization to produce battery storage products and components at Subzone 84AM in Brookshire, Texas. The authorization covers a 14-month period. Baker Hughes Oilfield Operations received a limited 2-year authorization for components used in electrical submersible pumping systems at Subzone 53D in Claremore, Oklahoma.

Coroplast Tape Corporation received authorization for pressure-sensitive tape production at Subzone 38W in Rock Hill, South Carolina. StandardAero San Antonio also received authorization for refurbished engine production within FTZ 80 in San Antonio, Texas. Unlike the Tesla and Baker Hughes decisions, these authorizations were not identified as subject to a specific time limit.

All four approvals remain subject to the FTZ Act, applicable Board regulations, and the restrictions that generally govern zone operations and production authority. Authorization does not eliminate the need for inventory controls, admission procedures, customs reporting, merchandise classification, recordkeeping, and ongoing coordination with the relevant FTZ grantee and U.S. Customs and Border Protection.

Two Activities Require Further Review

Stadler US did not receive authorization for passenger rolling stock production at Subzone 30G in Salt Lake City, Utah. AuroraTe likewise did not receive authorization for galvanized steel pipe production within FTZ 84 in Houston, Texas.

These outcomes do not necessarily represent permanent rejections. In each case, further review was found to be warranted. The applicant may pursue production authority through a full application under 15 CFR 400.23, which generally requires a more extensive review than the production notification procedure.

Limited Authorization Requires Early Expiration Planning

A time-limited authorization creates a defined compliance horizon. It allows production activity to proceed within the approved scope, but it also requires management to prepare for the point at which that authority expires. Companies should not treat a 14-month or 2-year authorization as equivalent to open-ended approval.

Build the Deadline Into the FTZ Compliance Calendar

The expiration date should be incorporated into the company’s FTZ calendar, internal control framework, and executive reporting. Relevant teams should identify the final date on which the approved production authority remains available, determine whether a follow-on filing may be appropriate, and establish internal milestones well before that date.

The planning period should account for legal review, preparation of technical descriptions, tariff classification validation, sourcing analysis, and coordination with the zone grantee. If broader review becomes necessary, the filing process may require detailed information about foreign-status inputs, domestic inputs, finished products, anticipated duty treatment, production volumes, scrap, waste, exports, and potential effects on domestic industry.

Monitor Operations Against the Authorized Scope

Time is not the only limitation that matters. Manufacturers must generally ensure that actual operations remain within the products, components, processes, and locations covered by the authorization. Changes to bills of material, suppliers, tariff classifications, production methods, or finished goods can create a gap between the approved activity and the company’s current operations.

A disciplined review should compare the authorization with live enterprise resource planning data, inventory records, admission data, and production transactions. Compliance teams should also document how foreign-status merchandise moves through production and how finished products, scrap, waste, and exports are reported.

For Tesla and Baker Hughes, the limited periods make this operational alignment especially important. Any decision to seek continued or modified authority should begin early enough to avoid an unplanned interruption in the intended FTZ duty treatment.

Further Review Changes the Path to Production Authority

A production notification offers a defined process for seeking authority to conduct manufacturing or processing activity within an FTZ. When the Board determines that further review is warranted, the activity generally cannot proceed under the requested notification authority. The company must decide whether to submit a full production application and support a more comprehensive evaluation.

A Full Application Demands a Stronger Business Case

For Stadler and AuroraTe, the practical next step is not simply to resubmit the same notification. A full application under 15 CFR 400.23 would generally need to address the proposed activity in greater depth. The applicant should be prepared to explain the manufacturing process, identify foreign components, quantify expected imports and exports, and describe the anticipated customs treatment of finished merchandise.

The analysis should also test whether the projected FTZ savings remain commercially meaningful after accounting for administrative costs, systems requirements, inventory controls, and the possibility of restrictions or conditions. Financial models should use validated tariff classifications and realistic sourcing assumptions rather than relying solely on headline duty rates.

The Board did not publicly provide detailed reasons for the Stadler and AuroraTe outcomes. That makes careful issue identification particularly important before a full application is prepared. Counsel, customs specialists, operational teams, and the FTZ grantee should evaluate where additional explanation or economic support may be needed.

Alternative Duty Strategies Should Be Evaluated in Parallel

A delayed or unavailable FTZ authorization does not mean that all duty recovery opportunities disappear. Depending on the company’s facts, duty drawback may provide refunds when imported merchandise, commercially interchangeable merchandise, or qualifying articles are exported or destroyed under customs supervision.

FTZ procedures and duty drawback are separate programs with distinct eligibility, documentation, timing, and filing requirements. Companies should generally model them independently and then evaluate how each program interacts with admissions, entries, exports, and inventory records. Controls are essential to prevent unsupported claims or duplicate benefits. For businesses with significant exports, drawback may complement an FTZ strategy or provide an alternative recovery path where its requirements are satisfied.

Frequently Asked Questions

What is FTZ production authority?

FTZ production authority allows an approved company to conduct specified manufacturing or processing activity within a U.S. foreign-trade zone or subzone. Depending on the merchandise and resulting product, the program may defer, reduce, or eliminate certain customs duties. Benefits depend on the authorized scope, tariff classifications, merchandise status, and disposition of the finished goods.

What is the difference between limited and unrestricted authorization?

A limited authorization includes a defined restriction, such as an expiration period or a narrower authorized scope. The Tesla authorization lasts 14 months, while the Baker Hughes authorization lasts 2 years. An authorization without a stated time limit is still subject to applicable FTZ requirements, operational conditions, and continuing compliance obligations.

What happens when an FTZ production notification is not authorized?

The proposed production activity generally cannot proceed under that notification. If further review is warranted, the applicant may seek authority through a full application under 15 CFR 400.23. The company should reassess the economic case, strengthen supporting information, and plan for a more detailed review before filing.

Can a company use duty drawback instead of an FTZ?

Potentially. Duty drawback generally refunds eligible duties, taxes, and fees associated with qualifying imported merchandise when statutory export or destruction requirements are met. It does not replicate every FTZ benefit, and eligibility depends on transaction-level facts. Companies should compare cash flow, data availability, export activity, compliance costs, and expected recovery under each program.

Can FTZ procedures and duty drawback be used by the same company?

Yes, a company may operate an FTZ program while also pursuing drawback for separate qualifying transactions. The programs must be managed carefully because merchandise status, entry type, export records, and prior duty treatment can affect drawback eligibility. Strong data governance is generally necessary to separate eligible claims and prevent duplicate recovery.

How Stable Software Can Help

Support a Broker-Led Drawback Strategy

When manufacturers evaluate FTZ authority, expiration risk, or alternative duty recovery options, customs brokers can help determine whether drawback fits the underlying import and export activity. DrawbackAI is flat-license duty drawback software that U.S. customs brokers can white-label for importer clients and use to file claims under their own filer codes.

Stable Software charges a flat software license and never takes a percentage of the refund. This structure allows brokers to build a duty drawback service without sharing a client’s recovery with the software provider. Brokers assessing opportunities created by changing FTZ authority can explore whether DrawbackAI supports a scalable, broker-controlled approach to eligible drawback claims.
