Classification of industrial grate under HS 8416.30
Industrial grates, specifically mechanical grates used in conjunction with furnaces, are classified under HS code 8416.30. This classification is situated within Chapter 84, which covers mechanical appliances. Heading 8416 is dedicated to furnace burners for liquid fuel, pulverized solid fuel, or gas, as well as mechanical stokers, mechanical grates, mechanical ash dischargers, and similar appliances. The inclusion of industrial grates under 8416.30 is based on their function as auxiliary equipment for the feeding and management of solid fuel within a combustion chamber. These components are essential for the automated movement of fuel and the removal of waste products like ash. The classification is driven by the mechanical nature of the device and its specialized role in industrial heating and furnace operations.

Codes often confused with 8416.30
Common mistake. Industrial grates are frequently misclassified under HS code 7326, which is a residual category for other articles of iron or steel. While grates are made of metal, the General Rules of Interpretation (GRI) dictate that specific functional headings take precedence over general material headings. Since the grate is a mechanical component of a furnace system, 8416.30 is more specific. Another confusion arises with HS code 8417, which covers the industrial furnaces themselves. While a grate is part of a furnace, when shipped as an individual mechanical component or accessory, it falls under 8416.30. It is also important to distinguish these from non-mechanical grates, which might fall under different headings depending on their design.

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).
