HS Code 2907.21 – Polyphenols; resorcinol and its salts
HS code 2907.21 is the 6-digit subheading for polyphenols, resorcinol and its salts. It is used for resorcinol, resorcinol monobenzoate, resorcinol formaldehyde resin, resorcinol-based adhesives and resorcinol derivatives.
What HS 2907.21 covers
This HS code specifically covers resorcinol and its salts, a key polyphenol with a broad range of industrial applications. Resorcinol is primarily used in the production of rubber products, where it acts as an adhesive promoter, enhancing tire performance. It's also vital in manufacturing specialty resins, dyes, UV stabilizers, and certain pharmaceuticals. Major importers are industries requiring high-performance polymers, advanced rubber compounds, and specialty chemicals. Exporters are typically large chemical producers with integrated manufacturing processes. The trade often involves bulk shipments to industrial users, with purity and specific grades being critical factors for different applications. Global demand is driven by the automotive, construction, and electronics sectors.

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).
