Product classification
HS code for Computer tower: 8471.50
Units of automatic data processing machines, processing units other than those of item no. 8471.41 or 8471.49, whether or not containing in the same housing one or two of the following types of unit: storage units, input units or output units.
Classification of computer tower under HS 8471.50
The classification of a computer tower under HS code 8471.50 is determined by its function as a processing unit for automatic data processing (ADP) machines. According to the General Rules for the Interpretation of the Harmonized System (GRI), specifically GRI 1, products are classified based on the terms of the headings and any relative section or chapter notes. A computer tower, which typically houses the central processing unit (CPU), primary memory (RAM), and the motherboard, meets the criteria for a processing unit as defined in Note 5 to Chapter 84. Even if the tower includes storage units like hard drives or input/output units like USB controllers, it remains under 8471.50 as long as it does not include a monitor or keyboard in the same housing. This code is specifically reserved for units that perform the logic and arithmetic functions of a computer system. It is important to note that the unit must be capable of being programmed in a language that can be executed by the user and must perform calculations without human intervention during the process. Furthermore, the unit must be able to process data according to a program that can be modified by the user. If the tower is imported as a barebones system (chassis and power supply only), it may be classified differently, but a functional processing unit is firmly within 8471.50. This classification ensures that the core brain of the computer is distinguished from peripheral devices or complete systems that include displays.

Codes often confused with 8471.50
Common mistake. Computer towers are frequently confused with HS code 8471.41, which covers complete ADP systems that include both a processing unit and an input/output unit (like a monitor and keyboard) in the same housing. Another common error is using 8473.30, which is reserved for parts and accessories of computers, such as empty cases or motherboards, rather than functional processing units. Additionally, industrial controllers may be misclassified here but often belong in 8537.
Top exporters and importers of HS 847150 (the code used for computer tower), 2025
In 2025, the largest exporter of HS 847150 (the code used for computer tower) in UN Comtrade data was Taiwan, with about 34% of world exports; the largest importer in UN Comtrade data was the United States, with 48% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 847150, not only computer tower.

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).
