Hydraulic Level Regulator for Fluid Tanks
This device automatically controls liquid levels in hydraulic tanks by measuring actual levels and adjusting inlet/outlet flows to stabilize at desired setpoints. It qualifies under HTS 9032.81.00.80 as other hydraulic automatic regulating apparatus for industrial fluid management. Excludes technical machine articles per chapter exclusions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If electrically operated rather than purely hydraulic/pneumatic
Electric automatic regulators shift to 9032.89 for other than hydraulic/pneumatic.
If components for liquid pumps with level control
Pump-integrated level controls excluded under note 1(g) and classify with pumps in 8413.
If for level/measuring instruments without regulation
Hydraulic level gauges without automatic control fall under 9026 for liquid level instruments.

Import Tips & Compliance
• Document sensor type (ultrasonic/float) and control algorithm to prove automatic per note 2(a)
• For hazardous fluids, include ATEX/CE certifications; U.S. importers need EPA compliance if applicable
• Avoid reclassification as tank parts (7309) by emphasizing standalone regulating function
