Central heating boilers; excluding those of heading no. 8402
In plain English
This heading covers central heating boilers, specifically excluding those classified under a different category. The goods are divided into two groups: the boilers themselves and the parts designed for these central heating boilers. Both categories exclude items from the other specified heading.
6-digit subheadings (2)
Official HS 2022 subheading texts. National tariff schedules subdivide these further (8-10 digit lines) and set the actual duty rates.
Chapter 84 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 in this chapter
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.
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.
