Products in this chapter are classified to a 6-digit HS subheading, then extended to the country full code (8–12 digits). Note the relevant Section and Chapter Notes — under GIR 1 they are legally binding for classification.

Scope and classification criteria

Chapter 84 covers nuclear reactors, boilers, machinery and mechanical appliances, including many automatic data-processing machines. Classification depends on the machine's objective function, construction and the legal Notes, not its trade name.

Common classification boundaries

Frequent boundary questions include complete machines versus parts, computers versus function-specific machines, and machines performing more than one function. Review Section XVI Notes 2, 3 and 4 and Chapter 84 Note 6 before selecting a heading.
