Tariffs to shift US Group III demand to Mideast Gulf

The prospect of higher US tariffs on South Korean and Indonesian imports is expected to make Group III base oils from the Mideast Gulf more attractive to US buyers.

US president Donald Trump signed an executive order to impose tariffs of 25pc and 32pc on all goods from South Korea and Indonesia, effective 1 August. This marks an escalation and delay of the initial tariff plan announced in April.

It is unclear whether refined oil products will be included in the latest announcement but it is separate to the existing tariffs on steel and auto part imports of 50pc and 25pc respectively.

Should base oils be included, US buyers will likely increase Group III imports from the Mideast Gulf, despite geopolitical uncertainties, as supplies from Asia look to surge in price.

The US is a net importer of Group III base oils, with production accounting for only 4pc of its nameplate capacity. Group III base oils are used for the production of full-synthetic and semi-synthetic finished lubricants. Which are predominantly used for passenger car motor oils.

South Korea accounted for 24pc of US base oil and lubricant imports at 532,300t in 2024, while Indonesia made up 4pc at 89,200t, US Energy Information Administration (EIA) data show. US imports from the Mideast Gulf made up 46pc in the same period at 1mn t.

Imports from the Mideast Gulf could increase given the end of maintenance at Bapco's 400,000t/yr Group III refinery in Sitra, Bahrain, and Adnoc's 500,000t/yr refinery in Abu Dhabi.

South Korean and Indonesian Group III suppliers are likely to target European buyers with their surplus, should these new tariffs be implemented. Europe is also a net importer of Group III supplies.

European Group III spot prices are the highest globally standing at $358/t premium to 4cst supplies on a fob Asia basis at $1,488/t, Argus assessments show on 7 July.

But more negotiations are likely to be had in the lead-up to the 1 August implementation of the new tariffs.
