Product classification

HS code for Test kits: 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.

Classification of test kits under HS 3822.19

Test kits are classified under HS code 3822.19 when they consist of diagnostic or laboratory reagents put up in the form of kits, provided they are not for specific diseases like malaria or Zika. This classification falls under Chapter 38, which covers miscellaneous chemical products. Heading 3822 was significantly updated in the 2022 HS nomenclature to group diagnostic reagents based on their application. Subheading 3822.19 serves as the "other" category for reagents on a backing or prepared reagents in kits. These products are characterized by their use in clinical, environmental, or food safety testing, where a chemical or biological reaction provides a diagnostic result. The kit must contain the essential reagents to perform the test, even if it also includes auxiliary items like swabs, tubes, or instructions.

Codes often confused with 3822.19

Common mistake. Test kits are frequently misclassified under HS code 3002.15 if they contain immunological products like antisera or antibodies. However, if the kit is a prepared diagnostic reagent, 3822.19 is generally preferred. Another common error is using 3006.30 for opacifying preparations or contrast media, which are used for imaging rather than laboratory diagnostic reactions.

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).
