HS Code 2907.23 – Polyphenols; 4,4'-isopropylidenediphenol (bisphenol A, diphenylolpropane) and its salts
HS code 2907.23 is the 6-digit subheading for polyphenols, 4,4'-isopropylidenediphenol (bisphenol A, diphenylolpropane) and its salts. It is used for bisphenol A, BPA-based polycarbonate, BPA-based epoxy resin, BPA derivatives and liquid BPA.
What HS 2907.23 covers
This HS code specifically covers 4,4'-isopropylidenediphenol, commonly known as Bisphenol A (BPA), and its salts. BPA is a high-volume chemical primarily used as a monomer in the production of polycarbonates and epoxy resins. These polymers are essential for manufacturing a vast array of products, including plastics for electronic components, automotive parts, protective coatings, and food and beverage containers. Its international trade is global, with large chemical companies exporting to manufacturers of consumer goods, construction materials, and industrial components. Environmental and health regulations often influence its trade dynamics, leading to shifts in demand and production methods. Trade volumes are substantial, reflecting its widespread industrial importance.

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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
