2704.00.00 - Coke and semicoke of coal, of lignite or of peat, whether or not agglomerated; retort carbon

This HTS category, 2704.00.00, encompasses coke and semicoke derived from coal, lignite, or peat. It also includes retort carbon, which is a carbonaceous residue produced in retorts. These materials are primarily characterized by their high carbon content and are often produced through high-temperature destructive distillation of organic matter in the absence of air. Coke, in particular, is a crucial byproduct of coal processing, widely used as a fuel and reducing agent in metallurgy, especially in blast furnaces for iron production. Semicoke, while similar, has a lower carbon content and higher volatile matter than coke.

Distinguishing this category from its siblings at the root level is essential for accurate classification. Unlike categories covering live animals (Chapters 01) or various processed goods, 2704.00.00 specifically deals with carbonaceous products derived from specific fossil fuels. Its placement within Section V, Chapter 27, emphasizes its classification as a mineral fuel product, separate from other mineral substances or manufactured goods.

Within this category, subcategories exist to further refine the classification. The primary subdivision often separates specific types of coke and semicoke (e.g., of coal) from "other" forms or products like retort carbon. This allows for more granular tracking and potential application of different tariff rates or trade regulations based on the precise origin and form of the carbonaceous material. The presence of a specific "Other" subheading indicates that while the primary focus is on coke and semicoke of coal, lignite, and peat, there may be other, less common retort carbon products or agglomerated forms that fall under this broader classification.
