2506.20.00.10 - Crude or roughly trimmed

This HTS classification, 2506.20.00.10, specifically covers crude or roughly trimmed quartzite. Quartzite is a hard, metamorphic rock composed primarily of quartz. The "crude or roughly trimmed" designation indicates that the material has undergone minimal processing beyond extraction. This includes pieces that may have been broken or shaped by natural processes or basic mechanical means, but have not been further worked by sawing, cutting into precise shapes, or polished.

Distinguishing this category from its sibling, 2506.20.00.80 (Other), is crucial. While both fall under quartzite, the "Other" category would encompass quartzite that has been further processed. This might include quartzite that has been sawn into blocks or slabs of a rectangular shape, or even pieces that have been polished. Therefore, the key differentiator is the level of processing; 2506.20.00.10 is for the raw, unrefined forms of quartzite.

As this is a leaf node, there are no further subcategories to introduce. The classification ends with the description of crude or roughly trimmed quartzite. This means that any quartzite falling under 2506.20.00 will either be classified here if it is crude/roughly trimmed, or under the sibling category if it has undergone further shaping. Practical classification relies on observing the physical state and the degree of alteration from its natural form, with this code specifically reserved for the least processed quartzite.
