Product classification
HS code for Gasket: 8484.10
Gaskets and similar joints, of metal sheeting combined with other material or two or more layers of metal.
Classification of gasket under HS 8484.10
HS Code 848410 is applied to gaskets and similar joints made of metal sheeting combined with other materials or consisting of two or more layers of metal. These are often referred to as composite gaskets. The classification is based on the construction method rather than the specific application. For example, a cylinder head gasket made of a layer of asbestos or synthetic fiber sandwiched between two layers of copper or steel is classified here. This code is essential for identifying high-performance sealing components used in internal combustion engines, pumps, and industrial piping where a simple single-material seal would be insufficient. The presence of metal provides structural integrity and heat resistance, while the secondary material ensures a tight seal against irregular surfaces. According to the Explanatory Notes to the Harmonized System, these items must be intended for joining two surfaces to prevent leaks. Single-layer metal gaskets are generally classified in Chapter 73, while single-layer rubber gaskets fall under Chapter 40.

Codes often confused with 8484.10
Common mistake. A frequent error is classifying these under 401693, which is for gaskets made purely of vulcanized rubber. Another common mistake is using 681299 for asbestos gaskets that do not contain metal sheeting. If the gasket is made of a single material, such as pure copper or pure aluminum, it should be classified by the constituent metal (e.g., 7419 or 7616).

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).
