FTZ Board Notices: Honeywell, Lilly, and Vulcaflex

The latest FTZ Board notices involving Honeywell Aerospace, Eli Lilly, and Vulcaflex illustrate three distinct stages of foreign-trade zone strategy. Together, the actions show why importers and customs brokers must distinguish production authority, site designation, activation, and ongoing duty management when evaluating FTZ benefits.

Honeywell's Production Notification Highlights Tariff Complexity

Honeywell Aerospace US LLC submitted a production notification for activity within FTZ 17 in Olathe, Kansas. The proposed scope includes aircraft components such as avionics installation kits, sensors, circuit card assemblies, and related products. The FTZ Board received the notification on September 9, 2026, and the public comment period is scheduled to close December 14, 2026.

Production notifications are important because FTZ designation alone does not generally authorize manufacturing or production. An operator may have an approved and activated zone site but still need separate FTZ Board authorization before conducting activity that substantially transforms imported merchandise or changes its tariff classification.

Evaluating the Potential Duty Benefit

The finished products covered by Honeywell's notification carry duty rates ranging from duty-free to 6.5 percent. Foreign-status components may carry rates ranging from duty-free to 9.0 percent. That rate relationship creates the possibility of an inverted tariff benefit when the duty rate applicable to an authorized finished product is lower than the rate applicable to imported components.

The actual financial result depends on more than comparing headline rates. Honeywell and its advisors must evaluate product classification, component origin, admission status, manufacturing yield, scrap, domestic consumption, exports, and special tariff measures. Some inputs may already enter duty-free, reducing the available FTZ benefit. Other inputs may be exported from the zone, which can generally support duty avoidance if all procedural requirements are satisfied.

Section 232 and Section 301 duties add another layer. Affected merchandise would generally need to be admitted in privileged foreign status under the applicable FTZ rules. Privileged foreign status typically preserves the tariff classification and duty treatment of the merchandise at admission, limiting the ability to obtain inverted tariff relief on those additional duties. The analysis must therefore separate ordinary customs duties from trade remedy duties rather than applying a single blended rate.

Eli Lilly and Vulcaflex Illustrate Different Subzone Actions

The Eli Lilly and Vulcaflex matters both concern subzone status, but they involve materially different administrative actions. Eli Lilly's application focuses on restructuring existing Indiana sites. Vulcaflex received approval for a new Alabama subzone. Neither action, by itself, grants new production authority.

Eli Lilly's Indiana Site Restructuring

The Indianapolis Airport Authority requested that Eli Lilly sites in Lebanon, Whitestown, and Brownsburg be moved from the alternative site framework into Subzone 72B under the traditional site framework. The affected locations include approximately 200 acres in Lebanon, 9.42 acres in Whitestown, and 18.98 acres in Brownsburg. The application also seeks removal of an existing Subzone 72B site.

This type of restructuring can align the legal FTZ configuration with a company's evolving operational footprint. It may support clearer site administration, long-term facility planning, and coordination among the grantee, operator, U.S. Customs and Border Protection, and the FTZ Board. However, the application does not request new production authority. Comments are scheduled to close December 14, 2026, with rebuttal submissions due December 28, 2026.

Vulcaflex's New Alabama Subzone

Vulcaflex Inc. received approval for Subzone 222D in Auburn, Alabama, on October 28, 2026. The approved site covers 26.64 acres at 3111 Haygood Court and remains subject to FTZ 222's 2,000-acre activation limit.

Subzone approval establishes the geographic and administrative basis for potential FTZ operations, but approval is not the same as activation. Before merchandise can generally receive FTZ treatment, the operator must complete the applicable activation process with CBP. If Vulcaflex later plans production activity, it may also need separate FTZ Board authorization. Brokers and compliance teams should therefore track site approval, activation, production authority, and inventory controls as separate workstreams.

Compliance and Duty Strategy Implications

The three FTZ Board actions demonstrate that zone strategy is both legal and operational. A favorable duty-rate comparison may support an FTZ business case, but the benefit can only be realized through accurate admissions, inventory controls, status designations, classifications, withdrawals, and entry filings.

Public Comments Require a Focused Trade Analysis

Companies with interests affected by the Honeywell or Eli Lilly matters may participate during the applicable comment windows. Effective comments generally address the economic, tariff, operational, or public-interest implications of the proposed action. Competitors, suppliers, local stakeholders, and other FTZ users should determine whether the requested authority or site structure could affect their operations.

Trade teams should confirm filing deadlines directly within the applicable proceeding and account for weekends, holidays, and rebuttal periods. Internal review should involve legal, customs, tax, finance, manufacturing, and supply chain personnel where the proposal could influence sourcing or market conditions.

FTZs and Duty Drawback Must Be Modeled Separately

Foreign-trade zones and duty drawback are separate duty management mechanisms. FTZ procedures generally manage when duty becomes payable and which duty treatment applies to merchandise entered from the zone into U.S. commerce. Duty drawback generally provides a refund of eligible duties, taxes, and fees after qualifying imported merchandise or substituted merchandise is exported or destroyed.

A company should not assume that an FTZ eliminates the need for drawback analysis. Some import and export flows may sit outside the zone, while other transactions may not produce a meaningful FTZ benefit. Conversely, merchandise admitted to or withdrawn from an FTZ can create specialized drawback considerations that require careful transaction-level review.

A sophisticated duty strategy compares the available approaches by product, facility, trade lane, tariff exposure, and disposition. The model should consider ordinary duties, Section 232 and Section 301 duties, merchandise processing fees, administrative costs, cash-flow timing, recordkeeping obligations, and restrictions on overlapping benefits. Customs brokers can add significant value by validating that the chosen program matches both the legal rules and the client's actual data environment.

Frequently Asked Questions

What Is an FTZ Production Notification?

An FTZ production notification is a request describing proposed manufacturing or production activity within an approved foreign-trade zone or subzone. It typically identifies the finished products, foreign-status components, and applicable duty rates. The FTZ Board reviews the proposed scope and may allow the activity, impose restrictions, or require a more extensive application process.

Does Subzone Approval Automatically Authorize Production?

No. Subzone approval generally establishes an approved FTZ site for a specific company or operation. Activation with CBP is usually required before FTZ procedures begin, and manufacturing or production may require separate FTZ Board authority. Companies should maintain a clear matrix of site approval, activation status, production scope, and any conditions attached to the authority.

Why Does Privileged Foreign Status Matter?

Privileged foreign status generally fixes the tariff classification and duty rate of foreign merchandise when it is admitted to the zone. This treatment may be mandatory for merchandise subject to certain Section 232 or Section 301 measures. Because the original duty treatment is preserved, privileged foreign status can prevent an operator from using a lower finished-product rate for those inputs.

Can a Company Use Both an FTZ and Duty Drawback?

A company may use FTZ procedures and duty drawback within the same broader supply chain, but it generally cannot receive duplicative duty benefits for the same liability. Eligibility depends on the specific admission, entry, export, destruction, and recordkeeping facts. Transaction-level controls are essential for separating FTZ flows from drawback-eligible activity and preventing unsupported claims.

What Should Customs Brokers Track for FTZ Clients?

Customs brokers should track zone status, activation, authorized production scope, merchandise status, tariff classification, trade remedy exposure, entry type, and export disposition. They should also reconcile zone data with import and export records. Where duty drawback is part of the strategy, the broker should establish controls that identify eligible transactions without duplicating FTZ benefits.

How Stable Software Can Help

Support a Broader Duty Recovery Strategy

FTZ activity can reduce or defer duty in qualifying circumstances, but it does not capture every potential refund opportunity. Customs brokers can use DrawbackAI to manage duty drawback programs for importer clients under the broker's own filer code. The software can be white-labeled, allowing the broker to maintain the client relationship and deliver the service through its own practice.

Stable Software charges a flat software license and never takes a percentage of the client's refund. For brokers evaluating FTZ and drawback opportunities across the same importer portfolio, that commercial model supports predictable software costs while preserving the full recovery value for the broker and importer.
