HS code for Burner caps: 7321.90
Domestic appliances, non-electric, parts thereof, of iron or steel.
Classification of burner caps under HS 7321.90
Burner caps are classified under HS code 7321.90 because they are identifiable parts of non-electric domestic cooking appliances, such as gas stoves, ranges, or plate warmers. According to the General Rules of Interpretation (GRI) 1 and 6, parts of appliances of heading 7321 are specifically provided for in subheading 7321.90. These components are typically made of cast iron, steel, or occasionally enameled iron, and are designed to sit atop the burner head to distribute the gas flame evenly across the cooking surface. Since they do not contain mechanical or electrical components themselves but are essential for the safe and efficient operation of the domestic heating or cooking unit, they fall squarely into this category. The material composition is a primary factor; while most are iron or steel, the heading specifically covers "parts thereof, of iron or steel." If a burner cap were made of a different material, such as pure copper, it might require classification under the respective metal chapter, though most commercial gas stove parts remain within 7321 due to their specialized design for these appliances.

Codes often confused with 7321.90
Common mistake. Burner caps are frequently misclassified under HS code 7321.11, which is reserved for complete gas-fueled cooking appliances. They are also often confused with HS code 8481.80, which covers taps, cocks, and valves for pipes or tanks; however, burner caps are passive components and do not regulate flow. Additionally, some importers mistakenly use 7326.90 for general iron or steel articles, but the specific provision for appliance parts in 7321.90 takes precedence.

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).
