Freight, tanker classes and delivery geometry

Why professionals care

Professionals use this page to understand how vessel size, route structure and terminal constraints reshape netback and delivered cost. It links price, specification, logistics, timing and risk into one operating picture.

Commercially, margin appears when one party can remove friction that another party cannot remove with the same speed, evidence or balance sheet.

What professionals check first

Before discussing price, teams usually test the physical boundary, the spec boundary, the document boundary and the credit boundary.

Operationally, the winning team is often the one that aligns nomination windows, documents, storage and credit before the molecule reaches the first chokepoint.

Typical bottlenecks

Bottlenecks usually appear when timing, tank space, blending room, credit lines, sanctions screening or sustainability evidence do not move at the same speed.

freight structure influences crude selection, refinery planning, freight exposure, document quality and downstream margin capture.
