Chapter 85 classification notes

High-value electronics. Many products duty-free under ITA/ITA-2. Anti-dumping duties on solar panels from China in US and EU. Lithium battery transport regulations (IATA DGR) apply in addition to customs. CE/FCC/UKCA marking requirements.

Frequent misclassification in this chapter

Many importers confuse 85 (electrical) and 84 (mechanical). A device with both elements usually classifies by principal function. Chargers and adapters classified separately from the device they charge.

Classification certainty

The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
