HS code for Conveyor parts: 8431.39
Machinery, parts of the machinery of heading no. 8428, (other than lifts, skip hoists or escalators).
Classification of conveyor parts under HS 8431.39
Conveyor parts are classified under HS code 843139. This code is situated within Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8431 is specifically designated for parts suitable for use solely or principally with the machinery of headings 8425 to 8430. Since conveyors and other continuous-action elevators are classified under heading 8428, their specialized components fall under 8431. To qualify for this code, the part must be identifiable as being intended for a conveyor system and must not be a general-purpose part (such as a standard bolt, nut, or engine) that is excluded by Section XVI Note 1 or 2. The classification relies on the "sole or principal use" rule, meaning the part's design must be unique to the operation of lifting or handling machinery.

Codes often confused with 8431.39
Common mistake. Parts are frequently misclassified under the code for the complete machine, such as 842833 or 842839. Another common error is classifying metal parts under 732690 (other articles of iron or steel). If a part is a general-purpose bearing, it must be classified under 8482, even if it is intended for a conveyor, due to the priority rules in Section XVI.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
