HS Code 3211.00 – Driers; prepared
HS code 3211.00 is the 6-digit subheading for driers, prepared. It is used for cobalt driers, manganese driers, zirconium driers, calcium driers and lead-free driers.
What HS 3211.00 covers
This HS code covers prepared driers, which are chemical additives used in paints, varnishes, inks, and other coatings to accelerate the drying and curing process. These are typically metal salts (e.g., cobalt, manganese, zirconium) dissolved in organic solvents or dispersed in water, acting as catalysts for oxidative polymerization. They are crucial for manufacturers to optimize production cycles and enhance product performance. Importers are primarily paint, ink, and coating manufacturers globally. Exporters are specialty chemical companies that formulate and produce these essential additives. International trade in driers requires careful handling due to their chemical nature and compliance with various safety and environmental regulations.

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).
