1806.20.20 - In blocks or slabs weighing 4.5 kg or more each

This HTS category, 1806.20.20, specifically classifies preparations containing cocoa in blocks or slabs, each weighing 4.5 kg or more. These are large format preparations, distinct from smaller bars or other forms. The key differentiating factor at this level is the significant weight of individual units, indicating bulk or industrial-sized packaging rather than individual consumer items.

While the immediate parent category (1806.20) broadly covers other preparations in bulk or large containers, this subcategory narrows the focus to solid forms exceeding a substantial weight threshold. It is crucial to distinguish these from items classified under "Other" at the same level, which would encompass a wider array of non-specific cocoa-containing preparations not meeting the block/slab and weight criteria defined here.

The subcategories within 1806.20.20 further refine the classification based on the presence or absence of milk solids. Subcategory 1806.20.20.10 pertains to preparations that do not contain any butterfat or other milk solids, often indicating a more pure cocoa preparation. Conversely, subcategory 1806.20.20.90 applies to those preparations that do incorporate butterfat or other milk solids, leading to a different compositional makeup and potentially affecting taste and texture.
