How much is the import duty on less than 2.93 kw per hour from Thailand?

A shipment of less than 2.93 kw per hour classified under HTS 8415.10.30 and made in Thailand currently pays a total of 25.00% in U.S. import duty. That total is built from two lines, not one: the Column 1 general rate of Free (this subheading is duty-free under the normal tariff), plus a Section 232 metals duty of 25.00% charged under Chapter 99. Customers who look up only the base rate in the tariff schedule and stop there are under-budgeting this shipment by 25.00%.

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 8415.10.30.40 itself at Free, the ordinary most-favoured-nation rate that applies to every origin with normal trade relations with the United States.

HTS 9903.82.09 adds 25.00% under Section 232, the national-security tariff on aluminium, 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-B (25%)").

Worked example: a $10,000 shipment

Take one ocean shipment of less than 2.93 kw per hour with an entered value of $10,000 — the customs value of the goods, before freight and insurance. At 25.00%, the duty is $2,500.00. Of that, $0.00 is the Column 1 duty and $2,500.00 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 $2,547.14, and the engine puts the landed cost of the goods at $12,547.14.

These are ad valorem rates, so a $100,000 entry of the same goods carries about $25,000 in duty, though MPF is capped per entry. Run your own value, entry date and HTS code through the tariff simulator for the same calculation against the same engine.

What changed, and when

The rate on this code has moved. Priced with an entry date of 15 October 2025, the same shipment would have paid 0% — the Column 1 rate alone, with no Chapter 99 line. Today it pays 25.00%, higher by 25.00 percentage points.

One thing that is often confused with this: IEEPA tariffs are not part of the calculation. The Supreme Court ruled against the IEEPA programme on 20 February 2026, and this engine applies no IEEPA duty on any entry date. Every line above is Section 301, 232, 201 or 122 — separate statutes, unaffected by that ruling.

An entry dated 15 May 2026 prices at 25.00%, 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 8415.10.30 from Thailand

Between March and July 2026 the U.S. imported $859 million under HTS 8415.10.30 from the 55 origins in this dataset; $538 million of it — 62.6% — came from Thailand, making Thailand the dominant supplier on this subheading. The largest were Thailand (62.6%), Indonesia (14.8%), Mexico (11.0%), China (10.5%) and Italy (0.8%).

Census also reports duty actually collected: entries of HTS 8415.10.30.40 from Thailand paid an average effective duty of 20.73% of value over those months. That is below the 25.00% priced here, which usually means part of that volume entered before the current measures took effect, or entered under a preference, an exclusion or a different 10-digit line. 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 8415.10.30.40, the largest 10-digit line under 8415.10.30 for Thailand by import value, and a neighbouring 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.
