HS code for Melamine sheets: 3920.93
Plastics, plates, sheets, film, foil and strip (not self-adhesive), of amino-resins, non-cellular and not reinforced, laminated, supported or similarly combined with other materials.
Classification of melamine sheets under HS 3920.93
Melamine sheets are classified under HS code 3920.93 because they are primarily composed of amino-resins, which are a specific category of thermosetting plastics. According to the General Rules of Interpretation (GRI) 1 and 6, products are classified based on the terms of the headings and any relative section or chapter notes. Heading 3920 specifically covers plates, sheets, film, foil, and strip of plastics that are non-cellular and not reinforced, laminated, or supported by other materials. Melamine, being a condensation product of melamine and formaldehyde, falls squarely into the amino-resin category. For a product to remain under 3920.93, it must not be combined with other materials like wood or metal in a way that changes its essential character to something other than a plastic sheet. Furthermore, the sheets must not be self-adhesive, as those would be classified under heading 3919. The classification also requires that the material has not been worked beyond surface treatment, such as being colored, printed, or polished. If the melamine sheet is reinforced with glass fibers or other textile materials, it would instead move to heading 3921. This specific code ensures that pure or nearly pure amino-resin sheets are tracked accurately for international trade statistics and tariff applications.

Codes often confused with 3920.93
Common mistake. Melamine sheets are frequently misclassified under HS code 4411.14 or 4412.39. This usually happens when the melamine is already bonded to a Medium Density Fiberboard (MDF) or plywood core. In such cases, the wood component provides the essential character, moving the classification to Chapter 44. Another common error is using HS code 3921.90, which is reserved for plastic sheets that are reinforced, laminated, or supported by other materials. If the melamine sheet contains a layer of paper or fabric reinforcement, 3921 is the correct heading. Additionally, 3919.90 is often incorrectly used for sheets that do not actually possess a self-adhesive backing.
Top exporters and importers of HS 392093 (the code used for melamine sheets), 2025
In 2025, the largest exporter of HS 392093 (the code used for melamine sheets) in UN Comtrade data was China, with 77% of world exports; the largest importer in UN Comtrade data was China, with 22% of world imports. Taiwan did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 24% of its exports here ($1.0M, CEPII BACI), so it may also belong among the top exporters. Vietnam did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 43% of its imports here ($1.0M, CEPII BACI), so it may rank higher.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
