FOR INDUSTRIAL MACHINERY & EQUIPMENT IMPORTERS
Industrial machinery importers: cut duty and recover overpayments on Chapter 84 & 85 equipment
Pumps, valves, engines, machine tools, and electrical machinery carry near-zero base duty — and a 15-50 point trade-remedy stack riding on the exact same classification. We help enterprise and mid-market importers classify BOMs correctly, price the full 2026 stack, and recover what was overpaid.
For industrial machinery, the base MFN duty is a rounding error — most of Chapter 84 runs 0-4.4%. The real cost is the trade-remedy stack riding on the same classification: Section 232 metals-derivative duties of 15-50% on the machine's full customs value (as of April 6, 2026), plus Section 301 China duties of 25% on Lists 1-3. A single mis-set heading or wrong metal-content call is a 15-50 point swing. Classifying the BOM correctly is both the compliance lever and the recovery lever. Verify current rates before you file.
The 2026 duty stack
What industrial machinery importers actually pay
A single imported machine or part can carry up to six stacked layers. The base rate is the smallest of them. Every rate below is perishable — the Section 232 regime moved three times in 2026 — so confirm the current status against CBP and USITC before you file.
Base MFN duty (HTS Chapter 84 & 85)
Most machinery carries a low General (Column 1) rate. Pumps (8413) run Free to ~2.5%; valves (8481.80.90) 2%; machine tools (8457) ~4.2-4.4%; engines 8407 at 2.5% and diesel 8408 Free; the catch-all 8479 ~2.5%. Verify the exact 8-digit rate on hts.usitc.gov — this layer is real but tiny next to the trade remedies below.
Section 232 metals derivative — the April 6, 2026 full-value change
As of 12:01 a.m. ET April 6, 2026, Section 232 on steel, aluminum, and copper articles AND their derivatives applies to the FULL customs value of the machine, regardless of metal content (Proclamation 11021; CBP CSMS #68253075). Before that date it was assessed only on metal content. Machinery was pulled in by the August 2025 expansion of 407 product categories, which explicitly named compressors, pumps, mobile cranes, and heavy equipment. Verify current status.
Section 232 — the five rate tiers CBP uses
CBP's April 2, 2026 fact sheet sets five categories on full customs value: 50% (article is almost entirely metal), 25% (derivative substantially made of metal), a temporary 15% floor for metal-intensive industrial equipment through December 31, 2027, 10% (≥85% U.S.-sourced metal), and 0% (metal is <15% by weight — EXCEPT goods in Chapters 72/73/74/76, which get no de-minimis). Which door a machine walks through is decided by its metal weight-percentage. Verify current status.
Section 301 (China) — Lists 1-3 machinery
Chapter 84 and 85 machinery sits heavily on Lists 1-3 at 25% (List 1 effective July 2018; List 3 September 2018); List 4A is 7.5%. Narrow categories carry higher post-2024 rates. Exclusions exist via the USTR portal. Confirm the specific 8-digit's list and current rate at ustr.gov before you file.
IEEPA status — struck down February 2026
On February 20, 2026, the Supreme Court held in Learning Resources, Inc. v. Trump (consolidated with Trump v. V.O.S. Selections) that IEEPA does not authorize tariffs, ending the reciprocal and trafficking tariffs. Section 232 and Section 301 are explicitly UNAFFECTED. IEEPA duties paid April 2025-February 2026 may be refundable; the mechanics remain unresolved. Verify current status.
Antidumping / countervailing duties (AD/CVD)
Product-specific orders bite machinery components hard and stack on top of 232/301 with no ad-valorem cap. Example: Tapered Roller Bearings from China carry an active antidumping order with reviews ongoing through 2026; order rates can exceed 100%. Screen every SKU for AD/CVD scope and confirm the current cash-deposit rate per order.
Merchandise Processing Fee + Harbor Maintenance Fee (FY2026)
MPF on formal entries is 0.3464% of entered value, minimum $33.58 and maximum $651.50, effective October 1, 2025. HMF is 0.125% on ocean cargo. These are small and fixed, but they apply on top of everything above.
Worked example. Worked example (as of July 2026, verify before filing): an industrial centrifugal pump, HTS 8413.70, from China, cast-iron and steel body, entered value $100,000. Base MFN ~1% = $1,000. Section 301 List 1 at 25% = $25,000. Section 232, now on full customs value, if the pump is 'substantially' metal at 25% = $25,000. MPF caps at $651.50; HMF (ocean) $125. Illustrative total ~$51,777 — roughly a 52% effective rate, of which ~$50,000 is trade remedies versus $1,000 of base duty. Note that the 232 tier depends entirely on the pump's metal-content determination: it could be 15%, 25%, or 50% on the same $100,000.
Recovery
How industrial machinery importers get duty back
For machinery, the highest-leverage recovery move is not a refund program — it is getting the classification right, because the 15-50 point trade-remedy layers ride on the same HTS decision as the base duty. Here are the four levers, ranked by impact for equipment importers.
1. BOM-to-HTS classification accuracy
This is the lowest-risk, highest-leverage lever. A machinery BOM is thousands of parts, and each mis-set heading or wrong Section XVI Note 2 parts call over- or under-pays base duty AND mis-assigns the Section 232 metal-content tier — a full-value rate swing. Our HTS Classification Researcher runs GRI 1-6 including 3(b) essential-character analysis, cites CROSS rulings, and produces audit-ready reports across the whole BOM. Correcting past entries runs through a Post Summary Correction (within ~300 days of entry) or a protest under 19 U.S.C. §1514 (within 180 days of liquidation). We do not file entries; we build the defensible classification the recovery rests on.
2. Foreign-Trade Zone (deferral + inverted tariff)
An FTZ is strong for machinery in two honest ways. Imported production equipment admitted to a zone pays no duty until it is assembled, installed, tested, and used in production — real deferral, and avoidance if re-exported before use. And the inverted-tariff election lets you pay the lower finished-good rate when it beats the components' rate. The honest limit: an FTZ does NOT avoid Section 232 or 301. Those goods must be admitted as 'privileged foreign status' and pay the applicable duty on entry for consumption. The zone helps the base layer and deferral, not the trade remedies. Our FTZ Savings Estimator models this.
3. Duty drawback (301 recoverable, 232 not)
If you import parts and re-export or destroy finished equipment, drawback under 19 U.S.C. §1313 recovers up to 99% of eligible duties, taxes, and fees. The load-bearing honesty point: Section 301 duties are drawback-eligible, but Section 232 duties are NOT (Proclamations 9739/9740). On a stacked China machine, you recover the 301 portion and not the 232 portion — most importers never split it. We size the opportunity with the Duty Drawback Estimator; a specialist partner executes the claims. We do not guarantee a recovery amount or CBP acceptance.
4. First Sale for Export
First Sale values the entry on the first (factory) sale in a multi-tier transaction rather than the last, shrinking the base on which every ad-valorem layer is computed — MFN, 301, and now the full-value Section 232. Because 232 is assessed on full customs value as of April 2026, the multiplier effect on machinery is larger than it used to be. It requires a bona-fide sale clearly destined for the U.S., with documentation to match. Our Trade Advisory scopes eligibility; this is duty-mitigation strategy, not legal counsel.
Classification
Getting industrial machinery HTS codes right
Industrial machinery lives in HTS Section XVI (Chapters 84 and 85), which is governed by its own Legal Notes that override the normal rules for parts and multi-machine goods. This is why equipment classification is genuinely hard, and why low base rates lull teams into treating it as low-stakes. Note 2 is the big one: a part that is itself a good of Chapter 84 or 85 (a motor, a pump, a valve) is classified in its own heading, not as a generic part; other parts 'solely or principally' for one machine go with that machine; everything else falls to residual baskets. Note 3 classifies a composite machine by its principal-function component. Note 4 treats separately shipped modules that contribute to one clearly defined function as a single functional unit — one HTS line, not many. Since April 2026, the classification decision also drives the Section 232 outcome: the same heading determines which of CBP's five metal-content tiers applies, so a wrong parts call is now a wrong 232 tier on the machine's full value. We approach this the way a compliance officer has to — GRI 1 through 6, essential-character analysis under GRI 3(b), CROSS rulings, and Section and Chapter Notes — applied across the whole BOM with an audit-ready reasoning trail, not a code guessed one SKU at a time.
Case law & tariff engineering
Precedents every industrial machinery importer should know
United States v. Carborundum Co., 536 F.2d 373 (CCPA 1976)
Established the 'Carborundum factors' — use, physical characteristics, channels of trade, marketing, trade recognition, economic practicality, and environment of sale — for deciding whether goods belong to a particular class or kind. The backbone of principal-use classification for machinery.
Bauerhin Technologies Ltd. P'ship v. United States, 110 F.3d 774 (Fed. Cir. 1997)
Reconciled the parts tests (integral and necessary to function) and defined an 'accessory' as something bearing only a direct relationship to the primary article. The parts-versus-accessories line that recurs across machinery rulings, and confirmation that Section XVI Note 2 can exclude an item from a parts heading.
Merritt v. Welsh, 104 U.S. 694 (1882)
The foundational tariff-engineering principle: importers may lawfully design or condition goods to attract a lower duty, provided the goods are honestly presented at the time of import. The legal basis for legitimate design-to-tariff.
Heartland By-Products, Inc. v. United States, 568 F.3d 1360 (Fed. Cir. 2009)
The limit on tariff engineering: an artificial condition that would never occur in normal commerce — added only to be removed after entry — is improper. Read alongside Merritt, it draws the honest line between engineering and manipulation.

FAQ
Industrial Machinery importer questions
Do Section 232 steel tariffs apply to imported industrial machinery?
Yes. The August 2025 expansion added 407 product categories to the steel and aluminum derivative lists, explicitly naming compressors, pumps, mobile cranes, and heavy equipment. Confirm whether your specific HTS code is on the current derivative list before you file.
Is Section 232 charged on the full value of a machine or just the steel content in 2026?
On the full customs value, regardless of metal content, as of April 6, 2026 (Proclamation 11021; CBP CSMS #68253075). Before that date it was assessed on metal content only. Verify current status, since this regime changed several times in 2026.
What is the Section 232 rate on industrial equipment — 25% or 50%?
It depends on how metal-intensive the machine is: 50% if it is almost entirely metal, 25% if it is a derivative substantially made of metal, and a temporary 15% floor for metal-intensive industrial equipment through December 31, 2027. The tier is decided by metal weight-percentage. Verify current status.
Is there a minimum metal content before Section 232 applies to a machine?
Yes — an article with less than 15% metal by weight is exempt, except for goods classified in HTS Chapters 72, 73, 74, and 76, which get no de-minimis (CBP CSMS #68253075). Our Tariff Calculator flags those chapters automatically.
Are Section 301 China tariffs still in effect on machinery after the IEEPA ruling?
Yes. The February 2026 Supreme Court decision struck down only IEEPA tariffs; Section 301 (25% on machinery Lists 1-3) and Section 232 are explicitly unaffected. Confirm the current rate for your HTS code at ustr.gov.
Can duty drawback recover Section 232 tariffs on re-exported equipment?
No — Section 232 duties are drawback-ineligible under Proclamations 9739/9740. Section 301 duties, by contrast, are drawback-eligible, so on a stacked China machine you can recover the 301 portion but not the 232 portion. We size the opportunity and a specialist partner executes the claim.
Does putting machinery in a Foreign-Trade Zone avoid Section 232 or 301 duties?
No. Such goods must be admitted as 'privileged foreign status' and pay the applicable duty on entry for consumption. An FTZ still gives you capital-equipment duty deferral and inverted-tariff relief on the base layer, which is where its real machinery value sits.
How do I classify a machine that performs two functions?
Classify it by the component that performs the principal function, under Section XVI Note 3. Separate modules connected only by piping or cables that contribute to one defined function are classified as a single functional unit under Note 4.
Is a component a 'part' or an 'accessory' for HTS purposes?
A part is integral and necessary — the machine cannot function without it (Willoughby Camera; Pompeo); an accessory bears only a direct relationship to the article (Bauerhin). The distinction changes the heading, and now the Section 232 tier as well.
How long do I have to recover an overpaid duty on a machine?
You can correct entry data through a Post Summary Correction within roughly 300 days of entry (before liquidation), or file a protest under 19 U.S.C. §1514 within 180 days of liquidation. Our Protest Deadline Calculator dates the window for a specific entry.
What is the base duty rate on pumps, valves, and machine tools imported to the US?
The base MFN rates are low: pumps (8413) run Free to ~2.5%, valves (8481.80.90) 2%, machine tools (8457) ~4.2-4.4%, and most engines 8407 at 2.5% and diesel 8408 Free — all before Section 301 and 232 are added. Verify the exact 8-digit rate on hts.usitc.gov.
How do I report steel or aluminum content on a Section 232 machinery entry?
Report the countries of melt and pour for steel and smelt and cast for aluminum, and file under the Chapter 99 headings 9903.81 (steel), 9903.85 (aluminum), or 9903.82 (copper), even under full-value assessment (CBP CSMS #68253075). We build the classification and content determination; we do not file the entry.
