Product classification
HS code for Rubber gaskets: 4016.93
Rubber, vulcanised (other than hard rubber), gaskets, washers and other seals, of non-cellular rubber.
Classification of rubber gaskets under HS 4016.93
Rubber gaskets, washers, and other seals are classified under HS code 4016.93. This classification falls under the broader heading 4016, which covers articles of vulcanized rubber other than hard rubber. Gaskets are essential components used to prevent leakage between two joined surfaces. The classification 4016.93 is specific to seals made of non-cellular vulcanized rubber. According to the Section XVI notes and Chapter 40 notes, these items remain in Chapter 40 even if they are intended for use in specific machinery, provided they are not part of a set or assortment of gaskets of different materials. The material must be vulcanized to ensure it is no longer thermoplastic, providing the necessary heat and chemical resistance required for sealing applications. This code covers a wide range of industrial and consumer sealing components that do not contain metal reinforcements that would change their primary classification to a composite article.

Codes often confused with 4016.93
Common mistake. A common misclassification occurs with HS code 8484.10, which covers gaskets and similar joints of metal sheeting combined with other material or of two or more layers of metal. If a rubber gasket is reinforced with metal or is part of a multi-material kit, it may move to 8484. Additionally, gaskets made of cellular rubber (foam) are classified under 4016.10. Purely plastic gaskets are classified under 3926.90. It is vital to determine the exact material composition and whether the item is a single material or a composite before assigning the code.

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).
