Datong Juqiang Activated Carbon Co., Ltd

The merchandise subject to this order is certain activated carbon. Certain activated carbon is a powdered, granular, or pelletized carbon product obtained by "activating" with heat and steam various materials containing carbon, including but not limited to coal (including bituminous, lignite, and anthracite), wood, coconut shells, olive stones, and peat. The thermal and steam treatments remove organic materials and create an internal pore structure in the carbon material. The producer can also use carbon dioxide gas (CO2) in place of steam in this process. The vast majority of the internal porosity developed during the high temperature steam (or CO2 gas) activated process is a direct result of oxidation of a portion of the solid carbon atoms in the raw material, converting them into a gaseous form of carbon. The scope of this order covers all forms of activated carbon that are activated by steam or CO2, regardless of the raw material, grade, mixture, additives, further washing or post-activation chemical treatment (chemical or water washing, chemical impregnation or other treatment), or product form. Unless specifically excluded, the scope of this order covers all physical forms of certain activated carbon, including powdered activated carbon ("PAC"), granular activated carbon ("GAC"), and pelletized activated carbon. Excluded from the scope of the order are chemically activated carbons. The carbon-based raw material used in the chemical activation process is treated with a strong chemical agent, including but not limited to phosphoric acid, zinc chloride sulfuric acid or potassium hydroxide, that dehydrates molecules in the raw material, and results in the formation of water that is removed from the raw material by moderate heat treatment. The activated carbon created by chemical activation has internal porosity developed primarily due to the action of the chemical dehydration agent. Chemically activated carbons are typically used to activate raw materials with a lignocellulosic component such as cellulose, including wood, sawdust, paper mill waste and peat. To the extent that an imported activated carbon product is a blend of steam and chemically activated carbons, products containing 50 percent or more steam (or CO2 gas) activated carbons are within this scope, and those containing more than 50 percent chemically activated carbons are outside this scope. This exclusion language regarding blended material applies only to mixtures of steam and chemically activated carbons. Also excluded from the scope are reactivated carbons. Reactivated carbons are previously used activated carbons that have had adsorbed materials removed from their pore structure after use through the application of heat, steam and/or chemicals. Also excluded from the scope is activated carbon cloth. Activated carbon cloth is a woven textile fabric made of or containing activated carbon fibers. It is used in masks and filters and clothing of various types where a woven format is required. Any activated carbon meeting the physical description of subject merchandise provided above that is not expressly excluded from the scope is included within this scope.
