Korean energy policyExpand nuclear power and renewable energy, and raise carbon reduction targetsMinistry of Trade, Industry and Energy's 2050 Net Zero Roadmap
Import dependenceEnergy self-sufficiency rate of approximately 2.5%, 100% dependence on imports for crude oil and petroleumKESIS Energy Statistics (2024)

South Korea is highly dependent on fossil fuel imports, including crude oil, refined oil, and LNG, and is sensitive to fluctuations in international oil prices and exchange rates.
As of the third quarter of 2025, OPEC+ production cuts and declining European inventories are contributing to rising oil prices.

Ⅱ. Analysis of Import Item Status and Characteristics

Data source

HS code27 (Mineral fuels, oils and distillate products)UN Comtrade
Main detailed itemsCrude oil (2709), refined petroleum (2710), liquefied petroleum gas (2711)Customs Service statistics
Major domestic import companiesSK Energy, GS Caltex, S-Oil, Hyundai OilbankIndustrial Yearbook
Import volumeApproximately USD 145.47 billion in 2024 (25% of total imports)Asian Exim Banks (2025)

HS27 accounts for approximately 25% of Korea's total imports and is a key input for the refining and petrochemical industries.

III. Characteristics of major importing countries and supply chains

Features and Risks

1Saudi Arabia27Long-term contract-based, stable supply
2USA22Shale oil price competitiveness and relatively stable logistics costs
3Kuwait15The impact of OPEC's supply control policy
4russia9Sanctions Risks Require Alternative Import Sources
5Indonesia7Increased maritime logistics costs in Southeast Asia

The top five countries account for over 80% of total imports, demonstrating a high degree of concentration. Geopolitical risks, particularly in Russia and the Middle East, are a significant short-term variable.

Refined oil (thousand tons)19,50020,400+4.6Some increase in demand for LNG alternatives
LNG (thousand tons)40,70038,200-6.1nuclear power substitution effect

The domestic refining capacity utilization rate averaged 87%, down 1.5 percentage points from the previous year. A decline in imports due to the expansion of nuclear power and renewable energy sources is evident.

Brent oil price (USD/bbl)82.184.388.9+5.5
Refining margin (USD/bbl)6.88.29.4+14.6
Average CIF unit priceUSD 756 / tonUSD 812 / tonUSD 845 / ton+4.1

As international oil prices and refining margins turn upward, there is upward pressure on domestic import prices.

Ⅵ. Seasonal patterns

season

characteristic

Import Volatility Index (0–1)

Winter (December–February)Growing demand for heating, leading to increased imports0.87
Spring (March–May)Regular maintenance and reduction period0.42
Summer (June–August)Increased revenue in response to peak electricity demand0.71
Fall (September–November)Slow income during the off-season0.55

Traditional seasonal patterns are maintained, with a particularly pronounced concentration of LNG and boiler fuel imports in winter.

VII. Tariff and Non-Tariff Barriers and Alternative Industries

item

detail

Tariff rateBasic 3%, tariff-free for most FTA countries
Non-tariff factorsEnvironmental regulations, carbon taxes, and national import quotas
Domestic alternativesSolar and wind power, hydrogen fuel cells

Environmental regulations and carbon prices, rather than tariffs, are actually acting as barriers.

Contribution to Net Zero Transition-Reduction target

As a fossil fuel product, it carries high ESG risks and is directly affected by the Carbon Emissions Trading Scheme and CBAM (Carbon Border Adjustment Tax).

Expected effect

1Diversification of import lines (expanding to the US and Southeast Asia)Supply stability ↑
2Long-term supply contract + logistics hedging strategyPrice risk ↓
3Fuel conversion in response to carbon tax and CBAMESG risk ↓

ⅩⅢ. General Conclusion

The Trade Index for South Korea's Import Items – Mineral Fuels and Oils (2025 Q3) 
is assessed at ΔImport = -0.4%, ΔPrice = +4.1%, and TrustIndex = 0.62 (Neutral).
Accelerating the energy transition and diversifying import sources are key policy priorities going forward, and AI Loop forecasts project a slight upward trend over the next three months.
