You're Paying Duty on Your Own US Components: Building a 9802/9801 US-Content Duty-Reduction Program

What is a 9802.00.80 US-content duty-reduction program?

A 9802.00.80 US-content duty-reduction program is a governed process for claiming HTSUS subheading 9802.00.80, which lets you pay duty on the value of the foreign assembly only and deduct the cost or value of the US-fabricated components you exported for that assembly. Paired with HTSUS 9801.00.10 for US goods returned unchanged, it stops a manufacturer from paying full duty on its own US content.

Does 9802.00.80 change the duty rate or the duty base?

It changes the base, not the rate. The same column-1 rate still applies, but under 9802.00.80 it applies to the full value of the imported article less the cost or value of the US-origin components, so duty falls on the foreign value-add rather than the entire assembled value.

If you export US-made components for assembly abroad and re-import the finished goods paying full duty on the entire value, US content included, you are almost certainly overpaying. The lever that fixes it is HTSUS 9802.00.80: articles assembled abroad from US-fabricated components are dutiable on the full value of the imported article "less the cost or, if no charge is made, the value of such products of the United States," which means the column-1 duty rate applies to the foreign assembly value, not to the US components you shipped out. Paired with HTSUS 9801.00.10 (US goods returned duty-free), it is one of the most underclaimed duty-reduction programs for manufacturers with US content. GingerControl is a trade compliance AI platform that classifies products, models the full US tariff stack, and simulates duty across sourcing and value scenarios, and its Product Sandbox lets you model the 9802 foreign value-add duty base and the resulting savings before you commit, on a low-barrier free-trial canvas that a hand-built spreadsheet cannot keep audit-ready. For a manufacturer exporting $8M a year of US-fabricated components for assembly abroad and re-importing $20M of finished goods, the difference between a full-value entry and a properly documented 9802.00.80 entry is duty on $20M versus duty on roughly $12M of foreign value-add, every year the program runs.

The pain: you fabricated it in the US, then paid duty on it again

If you run trade for a manufacturer with a cross-border assembly footprint, this is a duty dollar you are very likely giving back to CBP: you fabricate components in the United States, export them to a plant in Mexico, Canada, or Asia for assembly, and re-import the finished goods. On the entry, your broker declares the full transaction value of the finished article and pays the column-1 rate on all of it, including the value of the US steel, US circuit boards, US harnesses, or US castings you sent out in the first place.

The statute does not require that. HTSUS 9802.00.80 exists precisely so that US-origin components assembled abroad are backed out of the dutiable value. But the allowance is not automatic. It has to be claimed on the entry, and it has to be supported by the assembler's declaration and the importer's endorsement under 19 CFR 10.24, plus records that survive an audit. When no one owns that documentation, the path of least resistance is the full-value entry, and the overpayment compounds shipment after shipment.

The reason this stays unclaimed is almost never eligibility. It is program ownership. The US components are a procurement fact. The assembly happens at a contract manufacturer legal never visits. The entry is filed by a broker who declares what the commercial invoice shows. Nobody is positioned to connect "these components are US-origin" to "therefore they come out of the dutiable value," and nobody is holding the assembler's declaration that CBP will ask for. So a manufacturer with a clean 9802.00.80 claim sitting in front of it pays duty on its own US content instead.

Quotable insight: The 9802.00.80 duty allowance is not a rate reduction, and treating it like one is why so many manufacturers miss it. The column-1 rate never changes; the base does. Duty is assessed on the full value of the imported article minus the cost or value of the US-fabricated components you exported for assembly. A manufacturer paying full value on a re-imported assembly with 40% US content is paying the right rate on 100% of the value when the law lets it pay on 60%.

How 9802.00.80 actually works: the three-part test and the duty base

HTSUS 9802.00.80 covers articles "assembled abroad in whole or in part of fabricated components, the product of the United States." The duty treatment is a deduction from value, so the mechanics come down to two things: qualifying under the statutory conditions, and computing the base correctly.

The three-part eligibility test. Under the statutory language restated at 19 CFR 10.13 and implemented at 19 CFR 10.14, the US components must be:

Exported in condition ready for assembly without further fabrication;
Not lose their physical identity in the assembled article by change in form, shape, or otherwise; and
Not be advanced in value or improved in condition abroad except by being assembled and except by operations incidental to the assembly process.

Each condition is where claims are won or lost. A US casting that gets machined to final dimensions abroad has been "further fabricated" and fails condition one. A US coil slit and stamped abroad into a new part has lost its physical identity and fails condition two. The test is unforgiving on process, which is why the program has to sit next to the actual bill of process, not just the bill of materials.

What counts as incidental (and what disqualifies the claim). Condition three turns on the line between assembly-incidental operations and fabrication. 19 CFR 10.16 draws it explicitly:

Operations incidental to assembly (allowed)	Operations NOT incidental (disqualify the US-content allowance)
Cleaning, removing rust, grease, or paint	Machining, polishing, burnishing, peening
Application of paint or preservative coating, lubricants, protective encapsulation	Plating, other than plating incidental to the assembly
Trimming, filing, or cutting off small amounts of excess material	Chemical treatment, embossing, pressing, stamping, extruding, drawing
Adjustments in shape or form required by the assembly being performed	Annealing, tempering, case hardening
Cutting to length of wire, thread, tape, foil exported in continuous length	Any operation whose primary purpose is fabrication or physical or chemical improvement of a component

The duty base. The rate is unchanged. Under 9802.00.80 the column-1 rate applies to "the full value of the imported article, less the cost or, if no charge is made, the value of such products of the United States." So if a re-imported assembly has a $1,000 entered value and $400 of that is documented US-origin components, duty is assessed on $600 of foreign value-add. The savings is the rate multiplied by the deducted US content, and it repeats on every conforming entry.

GingerControl's Product Sandbox models exactly this, the full duty stack per cell against the 9802-reduced base, so a trade director can see the difference between a full-value entry and a foreign-value-add entry across an entire product line before deciding which flows to route through the program.

Where 9801.00.10 fits: US goods returned, and foreign goods returned within three years

9802.00.80 is for US components assembled into a new article abroad. Its companion, HTSUS 9801.00.10, is for goods that come back essentially as they left. It provides duty-free treatment for products of the United States returned after export without having been advanced in value or improved in condition while abroad, and, since the Trade Facilitation and Trade Enforcement Act of 2015, for any goods (including foreign-origin goods) returned within three years after export under the same unchanged-condition standard.

Two facts govern the program design:

US-origin returns have no time limit. A US-made article exported and returned unchanged is duty-free under 9801.00.10 regardless of how long it was abroad. Foreign-origin returns carry a three-year limit from the date of export, per the TFTEA amendment effective for entries on or after April 25, 2016 (CBP guidance in CSMS 17-000046).
The importer carries the burden of proof. CBP's updated 9801.00.10 guidance is explicit that the importer must be able to document US origin (or prior export for foreign goods) and unchanged condition. That is a recordkeeping program, not a checkbox.

For a manufacturer, 9801.00.10 captures the cases 9802 does not: US goods sent abroad for testing, exhibition, calibration, or return-and-repair that come back unaltered, and foreign inputs re-exported and returned inside the window. Running both provisions under one governance model is what turns scattered one-off claims into a US-content duty-reduction program.

What documentation CBP actually requires

The provisions live or die on documentation, and this is the part most stalled programs never build. For 9802.00.80, 19 CFR 10.24 requires two documents filed with the entry:

Declaration by the Assembler. The foreign party that performed the assembly declares that the article was assembled in whole or in part from fabricated components that are products of the United States, and lists the components, their unit values at the time and place of export from the US, the port and date of export, and the assembler's identity.
Endorsement by the Importer. The importer of record signs an endorsement affirming that the declaration and supporting information are correct and that there has been compliance with the applicable requirements.

Records supporting both must be retained by the importer and the assembler for five years from the date of the released entry and kept available for CBP audit. In lieu of filing duplicate component lists with every entry, the importer can arrange with the Center director to reference previously approved assembly descriptions and cost records, which is how high-volume programs stay manageable.

Two structural documentation facts round out the design:

Cut-to-shape US components in textiles get their own rule. Under 19 CFR 10.25, the value of components cut to shape in the US from foreign fabric and exported for assembly abroad is not included in the dutiable value of the finished article, a related but distinct allowance.
9801.00.10 has a parallel documentation standard. Per CBP's guidance and 19 CFR 10.1, the claimant must support US origin or prior export and unchanged condition, with a documentary threshold that scales with entered value.

As a government reference point for the whole program, CBP's Informed Compliance Publication What Every Member of the Trade Community Should Know About: Foreign Assembly of U.S. Components walks through 9802.00.80 eligibility and entry requirements in CBP's own words.

How 9802 interacts with Section 232, Section 301, and the IEEPA reciprocal tariffs

This is the nuance that decides how much the program is actually worth in the current environment, and it is where a lot of informal guidance is wrong. The 9802.00.80 US-content deduction is a valuation allowance under one heading. The special tariff programs are separate impositions, and each treats the base differently.

Section 232 (steel and aluminum). Section 232 duties, raised to 50% on steel and aluminum effective February 1, 2026, are unaffected by any court ruling and still apply. For 9802.00.80 assemblies, the additional Section 232 duty attaches to the dutiable (foreign) value-add, not to the deducted US components. Separately, for steel and aluminum derivative products in HTS Chapters 73 and 76, CBP guidance allows the Section 232 duty to be assessed on the reported metal content value rather than full customs value (Proclamation 10947, effective June 4, 2025), with steel melt-and-pour and aluminum smelt-and-cast reporting per CBP CSMS instructions. So a 9802 assembly with US steel content can compound two allowances: the US-component deduction on the base rate and the metal-content basis on the Section 232 line. One caution: this is specific to 9802.00.80 assembly. The neighboring provision 9802.00.60 (US metal processed abroad and returned) is treated differently, with Section 232 assessed on the full value, so the two 9802 subheadings should never be applied interchangeably.

Section 301 (China). Section 301 duties on Chinese-origin goods (Lists 1 through 3 at 25%, List 4A at 7.5%, with higher sector rates) also survived the 2026 Supreme Court decision and remain in force. Section 301 generally does not reach Chapter 98 provisions, but 9802.00.80 is one of the few it does apply to, and CBP's guidance is explicit that for 9802.00.80 the additional duty applies to "the value of the article less the cost or value of such products of the United States." So on a 9802.00.80 entry the Section 301 additional duty applies to the dutiable foreign value-add on the same reduced base, and the US-content deduction carries through both the base rate and the 301 line.

IEEPA reciprocal tariffs. The IEEPA-based "reciprocal" tariffs imposed in 2025 were struck down by the Supreme Court in Learning Resources, Inc. v. Trump on February 20, 2026; CBP ceased collecting IEEPA deposits on February 24, 2026, and is refunding paid amounts through the CAPE system that opened April 20, 2026. While in effect, that regime independently excluded US content through a separate mechanism: the reciprocal duty applied only to the non-US portion of an article where US content was at least 20% of the customs value, claimed on its own entry line. That was a value-share exclusion based on US-originating value, a different test from the 9802.00.80 component-cost deduction, and the two should not be conflated even though both can touch the same entry. The takeaway for program design is that US content has been a duty-reduction lever across multiple regimes at once, and the durable, statute-based version of that lever is 9802.00.80, which does not depend on an executive action that a court can vacate.

Program	Status (mid-2026)	Treatment of US content on a 9802.00.80 entry
Column-1 base duty	In force	US components deducted from the base; rate applies to foreign value-add
Section 232 steel/aluminum (50%)	In force	Applies to foreign value-add; derivatives may use metal-content basis (Ch. 73/76)
Section 301 China (7.5% to 25%+)	In force	Applies to foreign value-add on the same reduced base
IEEPA reciprocal tariffs	Struck down Feb 20, 2026; refunding via CAPE	Excluded US content (>=20%) while in effect; no longer collected

Whether that compounding is actually captured before entries post depends on what you use to model it:

Approach	Models the 9802 foreign value-add base	Carries the US-content deduction through 232 and 301	Audit trail for CF 28
GingerControl (Trade Advisory + Product Sandbox)	Yes, full entered value less US-component value, per product per source country	Yes, both additional-duty lines computed on the same reduced base	Yes, timestamped Selection History under 19 CFR 163.4
Contingency recovery vendor	No, optimizes one refund lever in isolation by design	No, will not model the deduction across the adjacent stack	Refund-claim records only
Hand-built duty spreadsheet	Partially, but each tab is hand-keyed and drifts from the schedule	Only if someone remembers to model both lines	Manual, rebuilt from memory at audit

Bottom line: For a manufacturer with meaningful US content in cross-border assemblies, the value is not any single provision, it is compounding the US-content deduction across the base rate and the surviving Section 232 and 301 lines at once. GingerControl's Product Sandbox models the full stack against the 9802-reduced base per product and per source country, so the deduction is visible on every line before entries post. A contingency recovery vendor optimizing one refund lever will not model how the US-content deduction carries through 232 and 301 on the flow next to it.

Standing up the program: from unclaimed lever to governed process

A US-content duty-reduction program is a routing-and-documentation discipline repeated across flows, then governed. The sequence that prevents the common failures looks like this.

Step 1, identify the US-content flows. Group activity by lifecycle, not part number: US components exported for foreign assembly and re-imported (9802.00.80 candidates), US goods exported and returned unchanged (9801.00.10, no time limit), and foreign goods re-exported and returned within three years (9801.00.10, time-limited). The provision follows the flow.

Step 2, run the three-part test against the bill of process. For each 9802 candidate, confirm the US components leave ready for assembly, keep their physical identity, and undergo only incidental operations abroad. This is where the 19 CFR 10.16 line matters, and where a bill of materials alone is not enough, you need the process.

Step 3, build the documentation spine. Stand up the assembler's declaration and importer's endorsement under 19 CFR 10.24, the US-origin support for 9801.00.10, and the five-year retention system. For high volume, arrange referenced component lists with the Center director so every entry does not re-file the same data.

Step 4, model the base and the stack. Compute the foreign value-add base and layer the surviving special duties (232, 301) on it to size the real savings per flow. This is the number that justifies the program to a CFO.

Step 5, govern it. Sourcing shifts, a component moves from a US supplier to a foreign one, a plant changes its process, a new Section 232 derivative list lands, and eligibility changes with it. GingerControl's Compliance Radar (in private beta) matches policy changes to your actual SKU records so the program updates when the rules do, instead of drifting until an audit finds a claim that no longer qualifies.

A worked illustration, not a promise about your numbers: take a manufacturer exporting $8M a year of US-fabricated components to a contract assembler abroad and re-importing $20M of finished goods, with the balance being foreign labor and foreign parts. Routed as full-value entries, the column-1 rate and any 232 or 301 lines hit the entire $20M. Routed through a documented 9802.00.80 program, the same rates hit roughly $12M of foreign value-add, and the US-content deduction carries through the 232 and 301 lines on the same reduced base. The point is not the arithmetic, it is that the deduction is available on every conforming entry and compounds across the stack, and that it is sitting unclaimed until someone owns the documentation.

GingerControl as the research and modeling layer, not your broker

A US-content duty-reduction program needs three things software supplies well, defensible classification, a duty stack you can trust, and a model that holds the base and the special duties together, and one thing software does not supply, the licensed and professional judgment that signs and files the entries.

GingerControl is a trade compliance AI platform that helps importers, exporters, and customs brokers classify products, simulate the full tariff stack, and model duty across value and sourcing scenarios. Its HTS Classification Researcher follows GRI logic and asks clarifying questions before assigning a code, producing audit-ready reports grounded in Section Notes, Chapter Notes, and CROSS rulings, because a 9802 claim still turns on the correct classification of the assembled article, and a 9801 claim on the identity of the returned good. Its Product Sandbox models the full duty stack per cell against the 9802-reduced base, and its Selection History keeps a timestamped audit trail built for CF 28 response under 19 CFR 163.4, which is exactly the record CBP tests when it examines a US-content deduction.

GingerControl is an HTS Classification Researcher. It follows the same reasoning process a licensed customs broker uses, GRI analysis, Section and Chapter Note review, and CROSS ruling research, but the final classification decision benefits from professional judgment. GingerControl produces audit-ready documentation that supports the classification decision; it does not provide legal advice or replace licensed customs expertise. Classifying specific goods beyond the 6-digit level and filing entries is customs business under CBP Ruling HQ H290535 and HQ H350722 (Jan 16, 2026); GingerControl's outputs are research for the importer and their licensed broker or counsel to review, structure, and file, including the 9802.00.80 assembler declaration and importer endorsement and the 9801.00.10 origin support. For the genuinely judgment-heavy work, whether a foreign operation stays incidental under 19 CFR 10.16, how to structure the assembler declaration, whether a returned good meets the 9801 unchanged-condition standard, GingerControl's Trade Advisory works the tariff-mitigation and documentation lane alongside your broker and counsel.

Frequently asked questions

How does GingerControl help a manufacturer claim 9802.00.80 on US components assembled abroad?

GingerControl models the 9802.00.80 duty base directly: it computes the foreign value-add (full entered value less the US-component cost or value) and layers the surviving Section 232 and 301 duties on that reduced base so you can see the savings per flow. For a manufacturer re-importing $20M of assemblies with 40% documented US content, that is the difference between duty on $20M and duty on roughly $12M. GingerControl's Product Sandbox surfaces this per product and per source country, and its HTS Classification Researcher confirms the classification of the assembled article that the claim depends on, unlike a spreadsheet model that cannot keep the reasoning audit-ready.

What is the difference between 9802.00.80 and 9801.00.10, and can GingerControl handle both?

9802.00.80 applies when US components are assembled into a new article abroad, and duty is charged on the foreign assembly value only. 9801.00.10 applies when goods return essentially unchanged, duty-free for US-origin goods with no time limit and for foreign-origin goods returned within three years. For a manufacturer running both, GingerControl's Product Sandbox models the duty impact of each flow and its Selection History preserves the classification and value records, so the two provisions run under one governed program rather than as disconnected one-off claims.

Do Section 232 and Section 301 duties still apply to a 9802.00.80 entry?

Yes, both survived the February 2026 Supreme Court IEEPA ruling and remain in force, but on a 9802.00.80 entry they apply to the dutiable foreign value-add, not to the deducted US components, so the US-content allowance carries through those lines too. For steel and aluminum derivatives in Chapters 73 and 76, the Section 232 duty may also be assessed on metal content value. GingerControl's Tariff Calculator separates the stack line by line against the 9802-reduced base, so a trade director sees exactly how far the US-content deduction reaches before entries are filed.

What documentation does CBP require for a 9802.00.80 claim, and does GingerControl produce it?

Under 19 CFR 10.24, CBP requires a declaration by the foreign assembler and an endorsement by the importer, with supporting records retained for five years. GingerControl does not file entries or sign the assembler declaration, that is your licensed broker's and the assembler's customs business, but its audit-ready classification reports and Selection History give your broker and Trade Advisory the defensible classification and value records the declaration references. For a compliance team standing up the program, that turns the documentation spine into a repeatable process rather than a scramble at audit.

Can operations performed abroad disqualify my US components from the 9802.00.80 allowance?

Yes. Under 19 CFR 10.16, only operations incidental to assembly, such as cleaning, trimming, painting, and adjustments required by the assembly, are permitted; machining, plating, chemical treatment, or any process that fabricates or improves a component disqualifies it. For a manufacturer whose US castings or coils are further worked abroad, that line is where claims fail. GingerControl's Trade Advisory works the eligibility analysis against your actual bill of process, and its Classification Researcher documents the reasoning, so the claim is tested before CBP tests it.

Is 9802.00.80 still worth claiming now that the IEEPA reciprocal tariffs were struck down?

More so, not less. The IEEPA reciprocal tariffs that excluded US content were vacated by the Supreme Court on February 20, 2026, but 9802.00.80 is a statutory provision that does not depend on an executive action a court can undo, and it compounds with the Section 232 and 301 duties that remain in force. GingerControl's Product Sandbox models the durable, statute-based US-content deduction across the surviving stack, so the program's value is grounded in the tariff schedule itself rather than in a policy that may change.

Who should own a US-content duty-reduction program, trade compliance or finance?

The portfolio view has to sit with someone who sees the US-content flows, the assembly process, and the entry filings at once, typically the trade director or a CFO-sponsored trade function, because the value is in connecting procurement facts to the dutiable value on the entry. GingerControl's Trade Advisory maps which provision owns which flow and structures the documentation, paired with Product Sandbox so the program is modeled, governed, and re-run when sourcing or process changes, instead of leaving the deduction unclaimed because no single team owns it.

Model your 9802 foreign value-add before your next entry posts

You already ship the US components. The cost is not a missing lever, it is filing full-value entries because no one owns the 9802.00.80 documentation and no one has modeled what the US-content deduction is worth across the base rate and the surviving Section 232 and 301 lines. GingerControl's Product Sandbox models the foreign value-add duty base and the resulting savings per product and per source country, and GingerControl's Trade Advisory structures the assembler declaration, the importer endorsement, and the 9801.00.10 origin support alongside your broker.
