What Machinery Imports Measure: Inside the $89.54B/month-a-Month Census Series

Machinery and Mechanical Appliances Imports track the customs value of U.S. imports under Harmonized System Chapter 84, engines, pumps, machine tools, industrial and computing equipment, and currently run $89.54B/month per month as of Aug 2026, per Census International Trade data, up about 61.6% from a year ago. It is the single largest capital-goods line in the U.S. trade accounts, and right now the trend reads as rising.

What Chapter 84 actually covers

Chapter 84 is the tariff schedule's catch-all for things that do mechanical work. It spans engines and turbines, pumps and compressors, air-handling and refrigeration equipment, machine tools for cutting and forming metal, semiconductor-fabrication equipment, construction and agricultural machinery, industrial ovens, and, less intuitively, computers, which the schedule classifies as automatic data processing machines. What it does not include matters just as much: electric motors, transformers, switchgear, and semiconductors themselves sit in Chapter 85; vehicles are in Chapter 87; and precision instruments live in Chapter 90. When a procurement lead reads that machinery imports hit $89.54B/month in a month, the figure is the mechanical-equipment slice of the import bill, not the whole capital-goods story.

How Census counts it

The series is a customs value: the appraised value of the goods at the border, before international freight, insurance, and duty are added. It is not a clean measure of equipment demand or physical units because prices, product mix, currency, and quantity all change. It also sits below what buyers pay to land a machine on the plant floor, where freight, duty, inland haulage, and rigging stack on top. Census compiles the figure monthly from customs filings rather than a survey, with roughly a five-week lag.

U.S. machinery imports per month, Aug 2026: $89.54B/month. The archived history ranges from $32.71B in Feb 2022 to $93.93B in Jul 2026.

What pushes the number up or down

Several forces can contribute. Capital projects may add equipment imports before commissioning. Prices, currency, and product mix can lift the dollar series without more machines, and the machinery PPI supplies context but is not a matched deflator that separates price from quantity. Tariff dates may change order timing, but the aggregate chart cannot establish a pull-forward without entry-level timing and comparison evidence. A single month is ambiguous; even the current multi-month rising direction remains a customs-value trend rather than a physical-volume or causal finding.

The trade line is a customs value, by the time a machine reaches your dock, freight, duty, and rigging have already made the real bill bigger.

The scale, annualized

At the current pace, the monthly Chapter 84 customs value annualizes to $1074.51B, roughly $2,985 million in declared value per day. A one-percent move in the monthly figure is about $895 million of customs value. Neither calculation converts the series into machine counts, freight demand, or physical equipment flow.
