Last updated: August 2026 dataPurpose-built for education, trade exhibitions, and classroom instruction, these instruments and models are classified on the basis of their unsuitability for any use other than demonstration — a functional limitation that distinguishes them from working instruments of identical appearance. Customs examiners may scrutinize whether an article is genuinely unsuitable for operational use or is simply a standard instrument marketed for demonstration, making the design specification and any physical limitations (non-functional components, simplified mechanisms) critical to supporting the classification claim.

Importers typically rely on manufacturer documentation showing the article lacks functional components necessary for operational use — for example, a simplified or non-calibrated mechanism, absence of measurement output, or design features that render it incapable of performing the function of its working counterpart. Technical specifications and product literature are the primary supporting documents.
No. The heading requires that the article be unsuitable for uses other than demonstration. A fully functional instrument that happens to be used for teaching purposes does not qualify; it would be classified under the heading appropriate to its operational function.
