API gravity, sulfur, residue behaviour and refinery fit determine how traders and refiners read a named grade.
This grade is read through its density, sulfur range, residue behaviour and benchmark linkage. Those variables shape refinery intake planning, hydrotreating load and the relative value of the stream against nearby alternatives.
Refinery interest depends on sulfur load, hydrogen balance, residue handling, diesel yield and marine fuel strategy. Buyers rarely read a grade in isolation; they read it inside a wider crude basket and against freight-adjusted alternatives.
A terminal system shapes title transfer, parcel formation, loading windows, draft restrictions, tank availability, inspection routines and freight optionality. Traders therefore evaluate terminals not as background logistics, but as part of the commercial identity of the barrel.
Pricing is interpreted through Brent-, WTI- or Dubai/Oman-linked differentials, freight and regional balances. Substitution economics versus similar grades can move faster than the headline benchmark itself.
