Production
Producing commercially valuable sandalwood with high levels of fragrance oils requires Indian sandalwood ('' S. album'') trees to be a minimum of 15 years old – the yield, quality and volume are still to be clearly understood. Yield of oil tends to vary depending on the age and location of the tree; usually, the older trees yield the highest oil content and quality. India continues to produce a superior quality of Santalum Album, with FP Aromatics being the largest exporter. Australia is the largest producer of ''S. album'', with the majority grown around Kununurra, in the far north of Western Australia by Quintis (formerly Tropical Forestry Services), which in 2017 controlled around 80% of the world's supply of Indian sandalwood, and Santanol. India used to be the world's biggest producer, but it has been overtaken by Australia in the 21st century.

Sandalwood has historically been an important tree in the development of the political economy of the Pacific. Prior to colonization in the region, the sandalwood tree was a marker of status, rank and beauty. It then became an important part of the Pacific trade during the colonial period, as it was one of the few resources the West was able to successfully trade with Chinese merchants. This western trade began to put pressure on the production of sandalwood in the region.

, a Polynesian kingdom in the Oceania region, saw a collapse of its sandalwood tree (locally known as 'ahi) due to the disruption of fahu, the hierarchical kinship-based social system which traditionally governed 'ahi harvest. As sandalwood became valuable in the market, lower-ranking family members began to harvest the trees without permission, encouraging many farmers to harvest their trees defensively, leading to overharvest. Nearly all of the sandalwood resources were depleted over the span of two years.
In 2007, Mike Evans published a scholarly report on Tongan sandalwood overharvest and the socio-environmental implications of resource commodification and privatized land tenure. Evan’s concluded that "whatever the short-term ecological benefits of enforcing privatized land tenure, because private property not only fragments social ties by allowing an individual to deny others, it has the potential to fragment the regional ecology as well."

Distillation
Oil is extracted from sandalwood through distillation. Many different methods are used, including steam distillation, water distillation, CO2 extraction, and solvent extractions. Steam distillation is the most common method used by sandalwood companies. It occurs in a four-step process, incorporating boiling, steaming, condensation, and separation. Water is heated to high temperatures () and is then passed through the wood. The oil is very tightly bound within the cellular structure of the wood, but can be released by the high heat of the steam. The mixture of steam and oil is then cooled and separated so that the essential oil can be collected. This process is much longer than any other
