Naphtha was 60% of Taiwan’s 2025 petroleum-product imports; diesel/gasoil was 17%.
This reframes the original diesel/gasoil supplier idea into the stronger source-backed product mix. EIA reports that naphtha made up 60% of Taiwan’s 2025 petroleum-product imports, with diesel/gasoil at 17% and liquefied petroleum gas at 13%. The supplier rows for diesel/gasoil still need Taiwan Customs extraction, so this page avoids a false country ranking. It is a cleaner import-structure graphic with the caveat visible.

This is not a diesel/gasoil supplier ranking. It is a product-type import mix from EIA/Vortexa data; detailed supplier rows require Taiwan Customs commodity-code extraction.
Uses EIA’s 2026 Taiwan Analysis Brief and Figure 11 workbook. Values are 2025 petroleum-product import shares by product type; b/d means barrels per day.
All product shares come from one EIA/Vortexa 2025 figure; supplier-country rows are intentionally not inferred.
