Are Oud Classifications Globally Standardized?

After explaining the grade names — Super, Double, Triple, Royal, Rare — we arrive at the question that gathers them all: are these classifications globally standardized? The short answer: no. There is no international body that governs oud grades, so their names differ from one seller to another and from one region to another. In this article we show why, and what that means for you as a buyer.

The short answer: no

There is no global authority that governs oud grades the way some commodities are governed by official specifications. Names like "Super" and "Royal" are not agreed-upon standard measures, but commercial terms each seller uses in their own way. And so "Super" from one seller may not equal "Super" from another, neither in the indicators nor in the price.

This does not mean the classifications are pointless; every serious seller has a consistent internal ladder — their grades ordered one above the other with a logic. But this ladder is local, not global; it compares that seller's grades with one another, not with anyone else's.

Why are there no unified standards?

For several reasons combined:

• Sorting is a human craft: it relies on the sorter's experience and taste, not on a device that gives a number, as we showed in how is oud sorted?
• Differing regional traditions: Indonesia's measures differ from India's and the Gulf's.
• The names are a marketing convention: they arose in the market, not in a lab, so they varied as the sellers varied.
• Multiple indicators: quality combines resin, color, sinking, and scent, and it is hard to reduce to a single number.

What does this mean for you as a buyer?

It means two practical things. First, do not compare prices by the grade name alone. "Super" from one seller at a low price may be below "Super" from another at a higher price; the honest comparison is by indicators, not by the name. Second, shift your focus from the names to what lies behind them: resin density, color, weight, sinking, scent, and a documented source.

And this is exactly what the next group of this guide explains: the physical and visual indicators that truly make quality, beginning with resin density. For once you master reading the indicators, the difference in names no longer matters to you, because you judge for yourself.
