HS Code 8473.30 – Machinery; parts and accessories (other than covers, carrying cases and the like) of the machines of heading no. 8471

HS code 8473.30 is the 6-digit subheading for machinery, parts and accessories (other than covers, carrying cases and the like) of the machines of heading no. 8471. It is used for RAM modules, solid State Drives (SSDs), motherboards, graphics Processing Units (GPUs) and central Processing Units (CPUs).

What HS 8473.30 covers

This HS code encompasses the vast and dynamic global trade of parts and accessories specifically designed for automatic data processing machines, as classified under heading 8471. This includes components that are integral to the function of computers, servers, and other digital processing units, but are not complete machines themselves. Major importers and exporters in this sector are typically large technology manufacturers, specialized component distributors, and electronics assembly plants worldwide. Key things to know include the rapid pace of technological obsolescence, the complexity of global supply chains involving numerous specialized manufacturers, and the significant impact of tariffs and trade policies on the cost and availability of these essential high-tech components. The market is driven by continuous innovation in computing power, storage, and connectivity, making it a critical segment for the entire digital economy.

Top exporters and importers of HS code 847330, 2025

In 2025, the largest exporter of HS code 847330 in UN Comtrade data was Taiwan, with about 26% of world exports; the largest importer in UN Comtrade data was the United States, with 30% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
