2711.29.00.25 - Other

This HTS category, "Other" under Butanes in the gaseous state, encompasses butane that does not meet the specific purity criteria of its sibling category. Specifically, it covers butane in its gaseous form that has a purity of less than 90 liquid volume percent. This classification is crucial for distinguishing between various grades of butane based on their composition.

The key differentiating factor from the sibling category, "Butanes with a purity of 90 liquid volume percent or more, but less than 95 liquid volume percent," lies solely in the liquid volume percentage of butane. If the butane is in a gaseous state and its purity falls below 90 liquid volume percent, it will be classified here. This distinction is important for trade and regulatory purposes, as different purities of butane may have varying applications and may be subject to different duties or controls.

As this is a leaf node, there are no further subcategories. Therefore, the classification for butane in a gaseous state with less than 90 liquid volume percent purity is final at this level. Importers and exporters should carefully analyze laboratory test results for purity to ensure accurate classification and compliance.
