About heading 9025
Hydrometers and similar floating instruments, thermometers, pyrometers, barometers, hygrometers and psychrometers, recording or not, and any combination of these instruments; parts and accessories thereof
Heading 9025 covers instruments that measure temperature, atmospheric pressure, humidity or liquid density: thermometers, pyrometers, barometers, hygrometers, psychrometers, hydrometers and recording versions of these, plus their parts and accessories. The heading splits first between thermometers and pyrometers not combined with other instruments (9025.11 for liquid-filled direct-reading types, 9025.19 for all others) and all other instruments (9025.80), with parts and accessories in 9025.90. Most lines in the heading are free of duty; the few dutiable lines are in 9025.80.
