Heading 3822

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, other than those of heading 3006; certified reference materials

8 declarable lines

Heading 3822 covers prepared diagnostic or laboratory reagents, with or without a backing, and kits of such reagents, plus certified reference materials. It excludes goods of heading 3006. The lines split first by specific use, such as malaria, Zika and other Aedes-borne diseases, and blood-grouping, then by other reagents, with separate lines for antigens or antisera, for products containing methyl chloroform or carbon tetrachloride, and for certified reference materials.

Products in this heading

  • Malaria rapid diagnostic test kit
  • Zika virus diagnostic test kit
  • Blood-grouping reagent for ABO typing
  • Laboratory reagent coated on a backing strip
  • Antigen or antiserum diagnostic reagent
  • Certified reference material for laboratory analysis
  • Prepared diagnostic kit for other diseases
  • Other diagnostic test kit, such as a pregnancy test

How to choose the right subheading

  • Decide whether the goods are a diagnostic or laboratory reagent or a certified reference material.
  • If the goods are a certified reference material, use 3822.90.00.00.
  • If the goods are for malaria, use 3822.11.00.00; if for Zika or other Aedes-borne diseases, use 3822.12.00.00; if for blood-grouping, use 3822.13.00.00.
  • For other diagnostic or laboratory reagents, check whether the product contains antigens or antisera.
  • Also check whether the product contains methyl chloroform or carbon tetrachloride, because that changes the 3822.19 line.
