Analysis
HTS 9025.90.06 covers parts and accessories under heading 9025 (hydrometers and similar floating instruments, thermometers, pyrometers, barometers…).
Within this group the rate runs from duty-free to 2.9%. Compared with 9025.80.20 (hydrometers and similar floating instruments, whether or not…), which pays 2.9%, a misclassification either way moves the duty by 2.9 percentage points.
The normal trade relations rate here is zero, shared by about 73% of the 296 tariff lines in chapter 90, a useful check when a neighbouring dutiable line is a candidate. Duty-free at the general rate does not rule out additional duties under Chapter 99, such as Section 301 or Section 232 measures, which depend on the country of origin.
Census statistics map these goods to NAICS 334519 (Other Measuring and Controlling Device Manufacturing), an industry of 913 US establishments employing 34,818 people. That concordance is how imports of this line are compared with US output.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
