HS Code 8457.30 – Metal machines; multi-station transfer machines, for working metal
HS code 8457.30 is the 6-digit subheading for metal machines, multi-station transfer machines, for working metal. It is used for rotary transfer machine, inline transfer machine, pallet transfer system, multi-spindle transfer machine and dedicated production line.
What HS 8457.30 covers
Multi-station transfer machines are highly specialized and automated production systems designed for sequential processing of metal workpieces through multiple distinct stations. Each station performs a specific operation (drilling, milling, boring, reaming, tapping), and workpieces are automatically transferred from one station to the next. These machines form the backbone of mass production, particularly in industries requiring high volumes of identical parts, such as automotive engine blocks, transmission housings, and hydraulic components. Major importers include countries with large-scale automotive and heavy machinery manufacturing, like China, USA, Germany, and India, seeking to achieve significant economies of scale. Exporters are typically highly industrialized nations with advanced machine tool engineering capabilities, such as Germany, Italy, Japan, and Switzerland. Key characteristics include their high throughput, precision, and ability to integrate various operations, significantly reducing cycle times and labor costs in dedicated production lines.

Codes often confused with 8457.30
Common mistake. Can be mistaken for machining centers (845710) due to multiple operations, but 845730 specifically refers to a "transfer machine" where the workpiece moves between distinct stations, unlike a machining center where operations occur in one setup.
Top exporters and importers of HS code 845730, 2025
In 2025, the largest exporter of HS code 845730 in UN Comtrade data was Italy, with 30% of world exports; the largest importer in UN Comtrade data was the United States, with 17% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
