Products classified under HTS 8411.21.40.00
PT6A-67A Turboprop Engine
The PT6A-67A is a turboprop engine manufactured by Pratt & Whitney Canada, designed for general aviation aircraft with power output under 1,100 kW. It features a free turbine design driving a propeller through a reduction gearbox, classifying under HTS 8411.21.40.00 as an aircraft turbine for turboprop applications.
TPE331-10 Turboprop Engine
Honeywell's TPE331-10 is a single-shaft turboprop engine delivering up to 1,000 kW for agricultural and utility aircraft. Its design integrates compressor, turbine, and propeller gearbox specifically for aviation, fitting HTS 8411.21.40.00 criteria for low-power aircraft turbines.
Garrett TPE331-1 Turboprop
The legacy Garrett (now Honeywell) TPE331-1 turboprop powers small aircraft like the Fairchild Merlin with under 1,100 kW output. Classified in HTS 8411.21.40.00 due to its aircraft-specific turboprop configuration and power rating.
Walter M601E Turboprop Engine
GE Aviation's Walter M601E is a compact turboprop for light aircraft like the L-410, rated below 1,100 kW. Its free-power turbine architecture qualifies it under HTS 8411.21.40.00 for aircraft turbopropellers.
Turbomeca Arriel 2D Turboshaft
Safran's Arriel 2D, though primarily turboshaft for helicopters, in low-power aircraft configurations falls under HTS 8411.21.40.00 when certified for fixed-wing turboprop use under 1,100 kW.
Rolls-Royce M250-C40B Turboprop
The Rolls-Royce M250-C40B is a lightweight turboprop variant for UAVs and small aircraft, outputting under 1,100 kW. It meets HTS 8411.21.40.00 for low-power aircraft gas turbines.
