U.S. imports of instruments, apparatus & models for demonstrational purposes, and parts (HS 902300) totaled $56.3M in July 2026, traded with 80 countries.
Importers of Instruments, Apparatus & Models for Demonstrational Purposes, and Parts paid $4.8M in duties in July 2026 — an effective duty rate of 11% on $42.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataClassified under a single 10-digit line (9023000000), demonstrational instruments and models occupy a narrow but commercially distinct niche: to qualify, an article must be designed exclusively for demonstration — in classrooms, trade shows, or training environments — and be unsuitable for any operational or productive use. China is the leading supplier, followed by Canada, Germany, Mexico, and the United Kingdom. The classification boundary between a working instrument used for training and a true demonstrational model is a recurring CBP audit issue, making accurate product documentation critical at entry.

CBP looks for objective evidence that the article cannot perform the function it depicts — for example, a cutaway engine model with no moving parts, or a circuit board replica with non-functional components. Product specifications, manufacturer documentation, and marketing materials that confirm the article's exclusive demonstrational purpose are the most persuasive supporting documents. If the article can operate even partially, it will likely be reclassified under its functional heading.
Generally no. A working prototype retains operational capability and would not meet the 'unsuitable for other uses' requirement. CBP has consistently held that functional capability — even if the article is only ever used for display — disqualifies it from this heading. The article must be inherently incapable of productive use, not merely intended for demonstration.
