Mastics, painters' fillings.
Classification of painter's putty under HS 3214.10
Painter's putty and similar fillings are classified under HS code 3214.10. This heading falls within Chapter 32, which covers tanning or dyeing extracts, paints, varnishes, and mastics. Specifically, 3214.10 includes glaziers' putty, grafting putty, resin cements, caulking compounds, and other mastics, as well as painters' fillings. The classification is based on the chemical composition and the intended use of the product as a filler or sealant. These products are typically used to fill cracks, holes, or joints in surfaces before painting or to seal glass in frames. The essential character of these items is their ability to harden after application, providing a smooth or sealed surface. The HS system groups these together because they share similar chemical bases, often involving oils, resins, or plastics mixed with fillers like chalk or clay. Whether the product is used for industrial construction or home repair, if it functions as a non-refractory surface preparation or a mastic, it belongs in this category.

Codes often confused with 3214.10
Common mistake. Painter's putty is often confused with HS code 3214.90, which is for other mastics and non-refractory surfacing preparations. While similar, 3214.10 is the specific sub-heading for putty and fillings. It is also sometimes misclassified under 3816.00, but that code is strictly for refractory cements and mortars which are designed to withstand high temperatures, unlike standard painter's putty.

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).
