Classification notes

One of the largest chapters by trade value. Many IT products duty-free under the ITA (Information Technology Agreement). Dual-use export controls apply to certain machinery. Parts often classified under the same heading as the complete machine.

Frequent misclassification

Many importers confuse Chapter 84 (mechanical) and Chapter 85 (electrical). A device with both elements usually classifies by principal function. Computer peripherals may classify separately from the computer itself.
