Machinery Import Duty, Without the Hand-Waving

Machinery's base MFN rate is 4.2% — genuinely low, a legacy of decades of trade liberalization. Then Section 301 List 1 stacks 25% on top, and your effective rate is 29.2%. The 4.2% is the number people remember. It's also the number that gets them burned.

Before you trust any rate
Every percentage below is a typical figure for a common HTS subheading. Machinery classification turns on function (milling vs. drilling vs. general purpose) and whether the code sits on Section 301 List 1. The only number that binds you is the 10-digit code on your commercial invoice. Our HS Code Duty Estimator gives a baseline; a machinery broker gives certainty.

Why "4.2% machinery duty" is a trap

MFN rates on machinery under Chapters 84 and 85 average about 4.2%, and some subcategories — certain industrial robots, specific machine-tool accessories, a handful of specialized apparatus — enter duty-free. That low base is real. But for Chinese-made machinery you don't just pay MFN. Section 301 List 1 adds a flat 25% on top of most industrial machinery classifications.

Stacked, that's 29.2% effective. Run it on a real purchase: a $50,000 CNC lathe, $3,000 freight and insurance, $53,000 CIF. MFN at 4.2% = $2,226. Section 301 at 25% = $13,250. Add MPF ($183.50) and HMF ($66.25) and you owe $15,725.75 — about 29.7% of CIF. The Section 301 portion alone is more than five times the MFN portion. The 4.2% base is almost a rounding error next to what List 1 adds.

The stack order matters: Section 301 applies on top of MFN, not instead of it. Customs computes MFN first, then layers Section 301 on the same entered value. That's why the combined rate is 29.2%, not 25%. Some importers assume the 25% replaces the base; it doesn't, and the CBP bill corrects them.

The Chapters 84/85 you'll live in

If a machine has two plausible functions, the HTS you pick can mean the difference between 4.2% and 29.2%. Apply the General Rules of Interpretation to its principal function — don't pick the lower code hoping no one notices. CBP's Machinery Center of Excellence (Laredo) knows these classifications inside out, and the five-year fraud lookback is real.

Why List 1 never got cut

List 1 was the opening shot of the 2018 trade action — $34 billion in Chinese imports at 25%, aimed squarely at "Made in China 2025" capital-goods sectors: industrial robots, CNC equipment, aerospace, medical, high-end machine tools. Lists 3 and 4A eventually dropped to 7.5% under the Phase One deal in 2020. List 1 has never been reduced — not once, in over seven years.

The durability is partly symbolic: it was the first list, the one that started the trade war, and neither administration has wanted to be seen folding on it. Lists 3 and 4A covered consumer goods where retailers screamed about costs; List 1 covers capital equipment, and factory owners have less political pull than Walmart. The result: machinery importers have eaten the full 25% for years, and should plan on eating it for the foreseeable future. When you model a multi-year import plan, build in a cushion for List 1 going back to 10% or 15% — it moved that fast once before, in 2019.

Duty by machine type

Not every machine is on List 1, though most industrial equipment is. The split that matters:

Duty by origin — the 25% changes the math

Because List 1 is China-only, origin is the single biggest lever. Once you add 25%, non-China sources can become cheaper even at a higher unit price.

Transshipping through Vietnam or Malaysia doesn't change origin if the machine was substantially made in China — and origin fraud carries seizure, civil penalties up to domestic value, and criminal referral. Don't let a sourcing agent sell you a "transshipment solution" that's fraud with extra steps.

Anti-dumping beyond Section 301

Section 301 isn't the only extra charge. Several Chinese machinery components carry separate AD/CVD orders — independent Commerce/ITC proceedings that stack on top:

AD deposits are set per producer and finalized in reviews taking 2–3 years — at which point you get a refund (with interest) or a bill (with interest). Your broker must screen every HTS code against both the Section 301 lists and the active AD/CVD list; missing one generates a CBP bill months later.

Compliance that isn't duty

The de minimis question — irrelevant for machinery

Section 321 waives duty under $800, and it works fine for e-commerce parcels. It does not work for machinery. What production equipment costs under $800? A replacement pump runs $1,500–$3,000; a spare gearbox more. For actual machinery, de minimis is a rounding error — plan on full formal entry every time. One narrow exception: a small demo component invoiced under $800 can enter under Section 321. Also note the De Minimis Reciprocity Act (bipartisan, not yet passed as of mid-2026) would strip de minimis for Chinese-origin goods entirely — worth watching.

How to actually estimate your landed cost

  1. Confirm the exact HTS code and List 1 status. A 10-digit code can mean 4.2% vs. 29.2%. Get a binding ruling from CBP if ambiguous — it's free, takes 30–60 days, and is binding at all ports.
  2. Budget on CIF, not EXW. Add inland China freight, ocean/air freight, and insurance. Assists count too. At 29.2%, the gap between EXW and CIF math is real money.
  3. Stack the layers: MFN + 25% Section 301 + MPF (0.3464%) + HMF (0.125% ocean) + any AD deposit.
  4. Screen for AD/CVD on every component code, separately from Section 301.
  5. Compare total landed cost vs. non-China origins before wiring the deposit.

Frequently asked questions

What's the real duty rate on Chinese machinery?

For List 1 machinery: 4.2% MFN + 25% Section 301 = 29.2%, plus MPF and HMF → about 29.7% of CIF all-in. Some subheadings are excluded or zero-rated, but most industrial equipment is on List 1. Verify your specific 10-digit code; don't assume.

Can I avoid Section 301 by shipping through a third country?

No. Country of origin — where the machine was manufactured — sets the rate, not the shipping route. A Chinese-made mill transloaded via Vietnam or Malaysia still carries Section 301. Origin fraud carries seizure, civil penalties up to domestic value, and criminal referral. CBP checks supply-chain docs, factory markings, and origin certificates.

Are there exclusions for Chinese machinery?

Narrow ones. USTR has granted product-specific exclusions where US buyers showed no non-Chinese alternative existed. If an exclusion is active for your code, any importer can claim it — not just the original applicant — and it's retroactive, so a broker can file a refund via Post-Summary Correction. Exclusions are temporary and reviewed on a cycle; one active last year may be gone now. Check the USTR portal and mark renewal dates.

Is used machinery treated differently?

Same HTS and same duty rates — used pays what new pays. What changes is valuation: CBP scrutinizes declared value harder without a clean factory invoice. Bring the original purchase invoice, a third-party appraisal, and condition photos. Also check OSHA/NFPA 79 — older Chinese machines often lack US workplace certifications.

What do machinery importers get wrong most often?

Underestimating the total. They see 4.2%, multiply the invoice by it, and miss Section 301 entirely — or assume it went away. They forget MPF/HMF, calculate on EXW instead of CIF, and skip the AD/CVD screen. Then the CBP bill arrives at three to four times the budget. Run the numbers the right way before you wire the deposit.
