4402.20.00.00 - Of shell or nut

HTS code 4402.20.00.00 specifically classifies wood charcoal derived from the shells or nuts of plants, excluding bamboo. This category encompasses charcoal produced by the pyrolysis of materials such as coconut shells, walnut shells, or other nut shells. These charcoals are typically used for various purposes including fuel for cooking, grilling, and activated carbon production.

This classification distinguishes itself from sibling category 4402.10.00.00, which exclusively covers charcoal made from bamboo. While both fall under the broader heading of wood charcoal, the feedstock material is the key differentiator. Goods classified under 4402.20.00.00 will consist primarily of carbonized shell or nut material, and will not be predominantly bamboo-based.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification hinges on accurately identifying the source material as shells or nuts, as opposed to bamboo. Importers and exporters should ensure documentation clearly indicates the specific type of shell or nut used in the charcoal's production to facilitate accurate customs clearance.
