Korea, China and Japan dominated Taiwan’s ethylene and propylene import bill.
Ethylene and propylene are basic petrochemical building blocks used across plastics, packaging, chemicals and electronics-linked materials. Taiwan’s supplier mix shows that Northeast Asian sources dominate its olefin feedstock exposure. The chart uses customs commodity codes, commonly called HS codes, and separates the two gases so the concentration is not hidden inside one total.

HS means Harmonized System customs code. This brief mixes the official MOF ethylene table with WITS HS 290122 propylene data, so it is source-labelled rather than same-source verified.
Ethylene values use Taiwan Ministry of Finance Table 9 selected-commodity data for 2024. Propylene values use World Bank WITS / UN Comtrade HS 290122 for Taiwan listed as Other Asia, nes. Values are current U.S. dollars, converted to millions.
Ethylene and propylene values come from two high-quality customs source paths, but not one single table.
