HS Code 2925.19 – Imides and their derivatives; other than saccharin and glutethimide (INN)

HS code 2925.19 is the 6-digit subheading for imides and their derivatives, other than saccharin and glutethimide (INN). It is used for phthalimide, succinimide, maleimide, N-methylphthalimide and glutarimide.

What HS 2925.19 covers

This category serves as a catch-all for various imides and their derivatives, excluding saccharin and glutethimide. These compounds are versatile chemical intermediates and active ingredients with diverse applications across multiple sectors. They are crucial in the synthesis of pharmaceuticals, agrochemicals (e.g., fungicides, herbicides), and high-performance polymers (e.g., polyimides). Importers and exporters are typically chemical manufacturers, research and development firms, and companies specializing in advanced materials. Key considerations for trade include the specific chemical structure and purity requirements for their intended end-use, as well as compliance with evolving chemical safety and environmental regulations.

Codes often confused with 2925.19

Common mistake. These imides are often confused with other nitrogen-function compounds in Chapter 29, particularly amides (2924) or heterocyclic compounds (2933, 2934), depending on their specific chemical structure and ring systems.

Top exporters and importers of HS code 292519, 2025

In 2025, the largest exporter of HS code 292519 in UN Comtrade data was China, with 22% of world exports; the largest importer in UN Comtrade data was the United States, with 11% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
