HS Code 9023.00 – Instruments, apparatus and models; designed for demonstrational purposes (in education or exhibitions), unsuitable for other uses

HS code 9023.00 is the 6-digit subheading for instruments, apparatus and models, designed for demonstrational purposes (in education or exhibitions), unsuitable for other uses. It is used for anatomical models, planetary globes, physics demonstration kits, chemical reaction models and architectural scale models.

What HS 9023.00 covers

This HS code encompasses instruments, apparatus, and models specifically designed for demonstrational purposes in educational settings or exhibitions, and which are unsuitable for other practical uses. International trade in these goods is primarily driven by educational institutions, science museums, and trade show organizers globally. Importers typically include universities, schools, and research centers seeking to enhance learning experiences, while exporters are often specialized manufacturers in countries with strong scientific and engineering sectors. Key aspects of this trade involve the accuracy and clarity of the demonstration, durability for repeated use, and compliance with educational standards. The market often sees demand for custom-made or highly specialized models, making it a niche but consistent segment of international commerce. These items are crucial for hands-on learning and visual explanation of complex concepts across various disciplines.

Codes often confused with 9023.00

Common mistake. This code can be confused with actual scientific instruments (e.g., 9027 for analytical instruments) if not clearly 'demonstrational only,' or with toys (9503) if simplified for children's play rather than educational demonstration.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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. 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).
