Usually there are 2 kinds of whole star anise based on the seasons: Spring and autumn. They have some differences in size and the oil content, but both are top quality and have fairly same price ranges at about $8300 per ton.
  • Broken star anise: This is a type of star anise that contains what can be called a “defective product” of whole star anise. They are the stars that are broken during the manufacturing process, or those that do not meet the requirements of quality star anise. Hence, the price would be much cheaper than whole star anise. To be specific, the price of broken star anise is very flexible based on the broken rate, with the lowest price at only about $6000 per ton. 
  • Star anise powder: Simply take the broken or whole star anise, ground it and you will get star anise powder. This type of star anise is mostly used to make dry seasonings, such as Chinese five-spices.

  • Autumn star anise: The star anise from this crop is larger in size. To be specific, they are normally about 2.5 to 3 mm in length. However, they have less essential oil than the Spring star, so overall the price of Autumn star anise is lower with lower quality.
  • Spring star anise: The better ones. These stars are smaller, only about 2 mm in length, with some of the biggest ones at about 2.5 mm. In exchange, they contain more essential oil, therefore the price is also higher.

Most people would just buy star anise with natural dry color, however in some cases, it is preferred by the buyers to have star anise with lighter and cleaner color.
