Class Codes & Rates:

Code 1472 is applied to wood distillation plants utilizing steam or destructive distillation processes. In both cases cord wood is purchased cut to size. In steam distillation plants it is necessary to grind the wood to produce chips to enable the steam to thoroughly saturate the wood being processed. In the destructive distillation process, which is comparable to charcoal manufacturing, cord wood is simply placed on steel carts and pushed into the retorts. The distillation of pine wood, by either method, to produce turpentine and various by-products such as pinene, camphine, etc., is also contemplated under this classification. After the wood has been relieved of all its turpentine, it is allowed to cool in an airtight container to prevent oxidation and is either sold as charcoal or ground up as chicken feed. This process is also known as the retort method and is substantially the standard method also followed in producing other wood by-products such as wood alcohol and acetic acid, which are joint products of the destructive distillation of certain hard wood. The manufacture of creosote from wood is also covered under Code 1472.
