HS code · 6-digit subheading
HS Code 3822.90 – Reagents; diagnostic or laboratory reagents on a backing, prepared diagnostic or laboratory reagents whether or not on a backing, or put up in the form of kits, other than those of heading 30.06; certified reference materials, n.e.c. in heading 3822
HS code 3822.90 is the 6-digit subheading for reagents, diagnostic or laboratory reagents on a backing, prepared diagnostic or laboratory reagents whether or not on a backing, or put up in the form of kits, other than those of heading 30.06, certified reference materials, n.e.c. in heading 3822. It is used for pH buffer solutions, chromatography standards, spectroscopy calibration solutions, certified reference materials for heavy metals and clinical chemistry controls.
What HS 3822.90 covers
This HS code serves as a broader 'other' category for diagnostic and laboratory reagents within heading 3822, explicitly excluding those of heading 30.06 (which covers specific pharmaceutical goods like blood fractions, vaccines, etc.) and importantly, includes certified reference materials. These items are fundamental for quality control, calibration, and general analytical work across diverse scientific and industrial sectors. Key importers and exporters include analytical laboratories, chemical manufacturers, research facilities, environmental testing agencies, and pharmaceutical companies. The trade emphasizes precision, purity, and certification, as these materials are often used for critical calibration, quality assurance, and method validation processes.

Codes often confused with 3822.90
Common mistake. This code can be confused with 382219 if the reagents are specifically on a backing or in kits, or with 3006 for certain pharmaceutical preparations, though this code explicitly excludes 3006.
Top exporters and importers of HS code 382290, 2025
In 2025, the largest exporter of HS code 382290 in UN Comtrade data was the United Kingdom, with 13% of world exports; the largest importer in UN Comtrade data was Hong Kong, with 7.8% 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).
