The demand in the last year far exceeded the supply. Prices have gone up and the plants that produce this oil are at full production making, it difficult for more material to be produced. Because this oil is used widely, we will see shortages in future years unless other plants are built to produce more oil. Because producers' profits are at breakeven levels, due to increased energy costs, it seems highly unlikely that the supply with increase to fill demand unless prices increase. China produces lots of material at half the cost of American oil prices, however, their quality is unacceptable for perfume or Aromatherapy applications.
Chinese oil is used to produce natural aromatic chemicals.
