Watch out on this chapter
Parts are classified with the machine they belong to only when they are not covered more specifically elsewhere. Getting a parts line wrong is the most common duty overpayment we see.
Column 1 General rates only. Section 301, Section 232, AD/CVD orders, MPF and HMF apply on top — see import duty rates for what stacks, and duty drawback if you have been overpaying.
Turn the code into landed cost
Duty is one line of the bill. Add freight, insurance, MPF, HMF and remedies to see what the shipment actually costs on arrival.
