Value depends on matching each cargo and blend to policy eligibility, logistics, unit limits, product markets and the refinery’s current operating state.
Four signals show why heavy-crude readiness depends on refinery-specific decisions, not nameplate capacity alone.
U.S. net imports from Venezuela reached 630 kb/d in June 2026, up from 200 kb/d in January.
Gulf Coast refinery utilization was 96.5% in the week ending 18 September 2026.

One historic grade marker is 10.7 API and 5.2% sulfur; each cargo still requires a current assay.
