8412.31.00.80 - Other

This HTS category, 8412.31.00.80, encompasses pneumatic power engines and motors of the linear acting type (cylinders) that are not specifically classified under the "tie-rod type" designation. These are devices that convert pneumatic energy into linear mechanical motion, commonly used for pushing, pulling, clamping, or lifting operations. They function by utilizing compressed air to drive a piston or rod within a cylinder.

The key differentiator between this category and its sibling, 8412.31.00.40 ("Tie-rod type"), lies in the structural design of the cylinder. While both are linear acting pneumatic actuators, the "tie-rod type" specifically refers to cylinders constructed with external tie rods to hold the end caps and cylinder barrel together. This category, "Other," captures all other linear acting pneumatic cylinders that do not meet the specific structural requirements of tie-rod construction, including but not limited to round-line cylinders, clevis-mounted cylinders, and other specialized mounting configurations.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the classification of goods under this heading relies on the precise determination that they are linear acting pneumatic cylinders and that they do not fall within the "tie-rod type" sibling category. Importers and exporters should carefully examine the physical construction and design of their pneumatic cylinders to ensure accurate classification.
