3105.10.00.00 - Products of this chapter in tablets or similar forms or in packages of a gross weight not exceeding 10 kg

HTS code 3105.10.00.00 encompasses mineral or chemical fertilizers that are presented in specific physical forms, namely tablets or similar forms, or in retail packaging with a gross weight not exceeding 10 kilograms. This category is intended for ready-to-use fertilizer products where the presentation and weight are key classification criteria, rather than the specific combination of fertilizing elements.

This classification is distinct from other categories within heading 3105 which are primarily defined by the chemical composition and the presence of nitrogen, phosphorus, and potassium. For instance, while other subheadings might detail fertilizers containing all three elements (3105.20.00.00) or specific combinations like nitrogen and phosphorus (3105.51.00.00 - assumed based on siblings) or phosphorus and potassium (3105.60.00.00), this code focuses on the *form* and *packaging size* of fertilizers that might otherwise fall under various combinations of these elements.

As this is a leaf node in the HTS database, there are no further subcategories under 3105.10.00.00. Therefore, the classification hinges entirely on the product being a fertilizer and meeting the specified criteria of being in tablet or similar form, or packaged in units up to 10 kg gross weight. Examples would include small, pre-portioned fertilizer tablets for houseplants or bags of granular fertilizer clearly labeled for consumer use and weighing 10 kg or less.
