How much is the import duty on seamless alloy steel pipe from China?
A shipment of seamless alloy steel pipe classified under HTS 7304.59.80 and made in China currently pays a total of 75.00% in U.S. import duty. That total stacks 3 separate lines: the Column 1 general rate of Free (duty-free under the normal tariff), plus a Section 232 metals duty of 50.00% and a Section 301 China list duty of 25.00%. Additional duties compound on the same entered value, so the arithmetic is a sum of rates rather than a rate applied to a rate.
The duty stack, line by line
U.S. duty on this code is assembled from separate legal instruments, each with its own authority. Here is what each line on the entry is:
The base line is HTS 7304.59.80.80 itself at Free, the ordinary most-favored-nation rate that applies to every origin with normal trade relations with the United States.
HTS 9903.82.02 adds 50.00% under Section 232, the national-security tariff on aluminum, steel and copper articles — it follows the article rather than the country, so changing origin does not remove it (engine label: "Section 232 metals Annex I-A (50%)").
HTS 9903.91.01 adds 25.00%: the Section 301 action against China, which charges an extra ad valorem duty on listed Chinese-origin goods on top of the normal rate — the engine's line reads "Section 301 China four-year review (25%)".
Because a Section 232 line and a Section 301 line are both present, the two stack: 232 attaches to the article (its metal or automotive content), 301 attaches to the origin. Sourcing the same article from a different country removes the 301 exposure but usually leaves the 232 exposure exactly where it was.
Worked example: a $10,000 shipment
Take one ocean shipment of seamless alloy steel pipe with an entered value of $10,000 — the customs value of the goods, before freight and insurance. At 75.00%, the duty is $7,500.00. Of that, $0.00 is the Column 1 duty and $7,500.00 is Chapter 99 additional duty. On top of the duty, the entry attracts a merchandise processing fee of $34.64 and, because it arrives by vessel, a harbor maintenance fee of $12.50. Duty and fees together come to $7,547.14, and the engine puts the landed cost of the goods at $17,547.14.
These are ad valorem rates, so a $100,000 entry of the same goods carries about $75,000 in duty, though MPF is capped per entry. Run your own value, entry date and HTS code through the import duty calculator for the same calculation against the same engine.
What changed, and when
The rate here has been stable across the period we can price: an entry dated 15 October 2025 pays the same 75.00% that applies today. Stability is not a promise — Chapter 99 lists are amended by notice, sometimes with days of warning — but this subheading has not been a moving target from China.
An entry dated 15 May 2026 prices at 75.00%, the same total as today. The Section 122 balance-of-payments surcharge in force over that window (24 February to 23 July 2026, since expired) did not attach to this code.
MPF, HMF and what else lands on the entry
Duty is not the whole bill to Customs. The merchandise processing fee is ad valorem with a statutory floor and ceiling per entry — $34.64 on this $10,000 example. The harbor maintenance fee is charged on vessel arrivals only, $12.50 here; the same shipment flown in would pay no HMF.
Not in any of these figures: antidumping and countervailing duties, excise taxes, quota charges, bond costs, and the freight and brokerage that make up the rest of your landed cost. AD/CVD is worth checking before you commit to a supplier — it is assessed on the producer and exporter, not just on the HTS code, and it can dwarf the tariff.
U.S. imports of 7304.59.80 from China
Between March and July 2026 the U.S. imported $55 million under HTS 7304.59.80 from the 55 origins in this dataset; $12 million of it — 22.5% — came from China, making China one of the larger suppliers on this subheading. The largest were Germany (30.6%), China (22.5%), Mexico (20.8%), Italy (12.0%) and Sweden (6.5%).
Census also reports duty actually collected: entries of HTS 7304.59.80.80 from China paid an average effective duty of 75.04% of value over those months. That tracks the 75.00% priced here closely, a good sign the stack above reflects what importers really pay. Treat it as a sanity check on your own numbers, not a forecast of your entry.

Planning around this number
Classification drives this: the page prices HTS 7304.59.80.80, the largest 10-digit line under 7304.59.80 for China by import value, and a neighboring line in the same subheading can carry different Chapter 99 exposure. Entry date matters as much as origin — the gap between the dates above is a change in law, not in your goods.

Common questions about duty on HTS 7304.59.80 from China
What is the total import duty on seamless alloy steel pipe (HTS 7304.59.80) from China?
75.00% of the entered value on an entry filed today. That is the Column 1 general rate of Free plus 2 Chapter 99 additional lines (9903.82.02 at 50.00% and 9903.91.01 at 25.00%). On a $10,000 entry that is $7,500.00 in duty, before MPF and HMF. It is an estimate for planning; CBP determines the final duty.
Which Section 301 list does HTS 7304.59.80 fall on?
The engine returns 9903.91.01 at 25.00% for this code — the engine's own label is "Section 301 China four-year review (25%)". Section 301 list membership is by 8-digit subheading, and exclusions come and go by Federal Register notice, so confirm the current status with your broker before you file.
Can I avoid the Section 232 duty by sourcing from another country?
Usually not. Section 232 is a national-security measure that attaches to the article — its metal, automotive or wood content — rather than to a particular trading partner, and on this code it appears as 9903.82.02 at 50.00%. Changing origin can remove a Section 301 line, but the 232 line generally travels with the goods. Whether a specific article falls inside or outside a 232 derivative annex is a determination for your broker.
Do I pay MPF and HMF on top of this duty?
Yes. On the $10,000 example the merchandise processing fee is $34.64 and, for a vessel arrival, the harbor maintenance fee is $12.50. Neither is included in the 75.00% duty rate. Antidumping and countervailing duties, excise taxes and quota charges are also outside these figures and are checked separately at entry.
How much does the U.S. import under HTS 7304.59.80 from China?
$12 million between March and July 2026, which is 22.5% of the $55 million the U.S. imported under this subheading from the 55 origins in this dataset over the same months. Source: U.S. Census Bureau, imports for consumption, March–July 2026.
What these figures assume
The tariff engine flags the limits of its own answer. These applied to this calculation:
- Civil aircraft carve-out not applied: set civil_aircraft=true if the goods are entered under the civil-aircraft certification (General Note 6)
- Section 301 forced-labor duty not applied: the goods are under a Section 232 heading listed in U.S. note 52(f) (heading 9903.05.90)
- Antidumping/countervailing duties, excise taxes and quota provisions are not included
- Section 232 derivative articles outside HTS chapters 72–76 (U.S. note 16 lists) are not evaluated
- MPF and HMF use FY2027 rates; HMF applies to vessel arrivals only
