Classification of dental impression material under HS 3407.00

Dental impression materials are classified under HS code 3407.00. This heading covers \"Modelling pastes, including those put up for children's amusement; preparations known as 'dental wax' or as 'dental impression compounds', put up in sets, in packings for retail sale or in plates, horseshoe shapes, sticks or similar forms; other preparations for use in dentistry, with a basis of plaster (of calcined gypsum or calcium sulphate).\" The classification is based on the material's composition and its use in creating molds or models of the teeth and gums. Unlike dental fillings (3006.40), which are permanent or semi-permanent restorative materials, impression materials are used temporarily to create a negative likeness of the oral cavity. This distinction is critical for customs purposes. The heading includes a wide variety of chemical bases, such as alginates, silicones, and polyethers, provided they are prepared and packaged for dental impression use. The classification follows the specific mention of dental preparations in the heading text of 3407.

Codes often confused with 3407.00

Common mistake. A common misclassification is HS code 3006.40, which is reserved for dental fillings and cements. Impression materials are not fillings; they are modeling compounds. Another error is classifying silicone-based impression materials under 3910.00 (silicones in primary forms). However, because these silicones are specially prepared and packaged for dental use as impression compounds, heading 3407.00 is more specific and takes precedence according to GRI 3(a).

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).
