Show the answer and walk-through
CBP's answer: B. B: 8481.80.9005
A solenoid valve is a valve of heading 8481, and Section XVII Note 2(e) takes articles of heading 8481 out of the vehicle parts heading 8708, so D is out. 8479.89 is a residual machinery heading and cannot be used when 8481 names the article. Applying GRIs 1 and 6, CBP's key puts this valve in the other-appliances subheading 8481.80.9005 (solenoid valves) rather than the 8481.20 subheading for valves for oleohydraulic or pneumatic transmissions, so B is right.
