Product classification
HS code for Metallic gasket: 8484.10
Gaskets and similar joints, of metal sheeting combined with other material or two or more layers of metal.
Classification of metallic gasket under HS 8484.10
Metallic gaskets are classified under HS code 848410. Heading 8484 covers gaskets and similar joints of metal sheeting combined with other material or of two or more layers of metal. The classification 848410 specifically targets these composite or multi-layered structures. These components are essential in mechanical assemblies to prevent leakage between joined parts, such as in automotive engines or industrial piping. The classification is driven by the construction of the gasket rather than the specific machine it is used in. According to the Explanatory Notes, this heading includes gaskets consisting of a core of asbestos, felt, or paperboard sandwiched between two metal sheets, or gaskets made of multiple layers of metal foil pressed together. This classification follows GRI 1 and GRI 6. It is important to note that the gasket must be a composite or multi-layer structure; single-layer metal gaskets are classified elsewhere based on their constituent material.

Codes often confused with 8484.10
Common mistake. Metallic gaskets are frequently confused with simple metal washers, which are classified under 7318 (for iron/steel) or 7415 (for copper). If a gasket is made of a single layer of metal, it does not fall under 848410 but is classified by material. Furthermore, sets or assortments of gaskets put up in pouches or similar packings are classified under 848490, not 848410. Purely rubber gaskets are classified under 4016.

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).
