There is currently no common standard methodology for grading agarwood and oud oil, with various retailers and countries adopting their own systems with limited science behind them. The quality or grade is known to be largely dependent on the resin saturation within the wood. However, other criteria, such as wood discolouration, fragrance level and an analysis of its chemical composition are often used in combination with one another.

Oud Oil Scent Characteristics by Country of Origin
Where the aquilaria trees were grown and associated natural elements such as tree species, soil, water, and age – in addition to the distillation technique used – all have an
effect on the smell of different oud oils. The regional scents differ in their characters and scent profiles, ranging from strong and earthy to sweet and ethereal. Each region and
aroma has something unique to offer.
Agarwood Oil Quality
Chemical composition analysis [primarily gas chromatograph and mass spectrometry analysis (GC-MS)] has recently begun being implemented in the industry after it was found to accurately identify the major compounds that distinguish oil quality. However, despite this grading technique being more efficient and standardised than the traditional approach, the majority of grading in the market is still dependent on the traditional method of using one’s senses – which are varied and subjective.
