US imports of Self-propelled bulldozers, angledozers, graders, levelers

US imports under HTS 8429 at a glance

Between March and July 2026, US importers entered $4.14 billion of self-propelled bulldozers, angledozers, graders, levelers under HTS heading 8429, from 27 of the 55 origin countries covered here and across 41 ten-digit tariff lines — roughly $828 million a month of customs value under a single four-digit heading.

Heading 8429 sits in chapter 84, machinery, mechanical appliances and computers, so anything classified here shares a duty structure with the rest of that chapter.

Who exports self-propelled bulldozers, angledozers, graders, levelers to the United States

Japan is the largest origin with $2.02 billion, or 48.9% of the heading, with Brazil at 12% and South Korea at 6.4%. The top three take 67.3% between them — enough concentration to matter when one origin's duty treatment changes, but not so much that a buyer has no alternative to qualify.

Asian origins supply 64.5% of the heading, led by Japan, South Korea, China and Thailand. That means ocean transit from Asian base ports and, for most of these countries, no free-trade-agreement relief — so the tariff line you classify into carries the full cost.

What importers actually paid in duty

Almost everything under this heading is dutiable: 97.2% of entered value carried duty, and CBP collected $885 million over the five months. The effective rate on dutiable value was 22%, which works out to $21.39 of duty per $100 of goods. There is no meaningful duty-free channel here — classification and origin are the only levers.

The spread between origins is real. Among origins with at least 2% of the heading, China paid the most duty relative to value — $48.15 per $100 — while Italy paid $18.22. On a $250,000 purchase order that gap is about $75,000 in duty alone, which is worth pricing into a sourcing decision rather than discovering on the entry summary.

The 10-digit lines under heading 8429

41 ten-digit lines carried trade under this heading in the period. The largest, 8429.52.10.10 (backhoes, shovels, clamshells and draglines), took 47.8% of the heading at $1.98 billion. 8429.40.00.20, 8429.11.00.10 and 8429.51.10.15 follow. Rates diverge between those lines, so the classification your broker files is worth checking against the goods rather than carried over from the last entry.

What the duty stack looks like

The rate on an entry is not one number. It is a stack: the general (column 1) rate for the 10-digit line, less any trade-agreement preference the goods qualify for, plus whatever additional duties apply to that product and origin, all applied to the customs value declared. The $21.39 per $100 above is what that stack averaged across every entry in this heading — a benchmark, not a quote.

For the origins carrying the most volume, the per-country breakdowns go a level deeper: Japan (8429.52.10), Brazil (8429.51.10) and South Korea (8429.52.10). To price a specific shipment, put your 10-digit code and country of origin into the tariff simulator.

What this means for your next shipment

Classify first, confirm origin second, quote freight third. A heading like 8429 rewards that order, because the duty differences between lines and between origins are usually larger than the freight differences on the same lane. Airlift USA handles the freight and coordinates classification and entry through our licensed broker network.
