HS Code 3822.19 – Reagents; diagnostic or laboratory reagents on a backing, prepared diagnostic or laboratory reagents whether or not on a backing, whether or not put up in the form of kits; n.e.c.in item 3822.1
HS code 3822.19 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, whether or not put up in the form of kits, n.e.c.in item 3822.1. It is used for ELISA test kits, lateral flow assay strips, PCR reagent panels, blood glucose test strips and rapid antigen test kits.
What HS 3822.19 covers
This HS code encompasses a specialized category of diagnostic and laboratory reagents, particularly those presented on a backing or assembled into kits, not specifically classified elsewhere within the broader 3822.1 subheading. These products are critical for medical diagnostics, scientific research, and quality control across various industries. Major importers and exporters include pharmaceutical giants, hospitals, academic research institutions, and specialized biotech firms. The trade in these goods is characterized by stringent regulatory requirements, often demanding cold chain logistics to maintain product integrity, and a high premium on precision and reliability. They are essential for detecting diseases, analyzing biological samples, and performing complex chemical assays, making them indispensable in modern healthcare and scientific advancement.

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).
