<h1>Indian government's announced halt to Russian oil purchases raises contractual, trade-law and supply-chain disruption risks for refiners and buyers</h1> A diplomatic claim that the Indian government will halt purchases of Russian oil raises legal and commercial issues: long-lead commercial crude contracts typically lock deliveries 4-6 weeks ahead, so immediate cessation is contractually impracticable; refiners face performance and supply-chain obligations. There is no general international prohibition on buying Russian crude, but an EU ban on products refined from Russian crude and a multilateral price cap regime impose compliance and reputational constraints. Shifting imports would entail significant contractual, logistical and economic trade-offs, potential price-risk exposure, and the need to renegotiate or decline future cargoes within existing contractual and trade-law frameworks.
