Bromochloromethane Calibration Standard
This is a certified reference material consisting of bromochloromethane in a solvent matrix, used to calibrate gas chromatography equipment for environmental testing. It falls under tariff item 3827.40.00 because it is a mixture containing bromochloromethane, which is specifically named in the item description. Although chapter note 2 gives heading 38.22 precedence for certified reference materials, this product is not a certified reference material as defined there because it lacks a certificate indicating property values and methods.
