Last updated: April 2026 dataParts and accessories specifically for electronic calculators and calculating machines — as distinct from parts for general ADP computers — are classified under this heading, which covers a narrower product universe than the broader ADP parts heading 8473.30. South Korea leads US import supply, followed by China, Thailand, Malaysia, and Taiwan, reflecting the concentration of calculator manufacturing and component supply chains in East and Southeast Asia. Importers should confirm that the parts are specifically designed for calculating machines rather than for general-purpose computers, as the latter would fall under heading 8473.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Parts under 8473.21 must be specifically designed for or principally used with electronic calculators — devices whose primary function is mathematical calculation rather than general data processing. Parts that are interchangeable between calculators and computers, or that are designed for general ADP machines, are typically classified under 8473.30. The key classification factor is the article's design specificity and principal use.
Display modules and keypads specifically designed for electronic calculators are generally classifiable as parts under 8473.21, provided they are not more specifically described by another heading (for example, liquid crystal displays may be classified under heading 9013 if presented separately). Importers should assess whether the component is presented as a dedicated calculator part or as a general-purpose electronic component.
