About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS classification, 8412.39.00.40, specifically covers "Unlimited rotary acting" pneumatic power engines and motors. These are devices that convert pneumatic energy into continuous rotary motion. The "unlimited rotary" aspect distinguishes them from pneumatic motors that have a limited angle of rotation (e.g., pneumatic actuators). Examples include certain types of air motors designed for continuous rotation, often used in industrial machinery for driving pumps, mixers, or conveyors where a constant, unobstructed rotational output is required.

Within the broader category of "Pneumatic power engines and motors: Other" (8412.39), this subcategory is distinct from its sibling, 8412.39.00.80, which is designated for "Other" pneumatic motors and engines not otherwise specified. The key differentiating factor is the specific functional characteristic of unlimited rotary action.

As this classification is a leaf node, there are no further subcategories. Therefore, the focus for classification within 8412.39.00.40 rests on accurately identifying pneumatic power engines and motors that exhibit continuous, unlimited rotational capability, as opposed to those with limited angular displacement. Classification will depend on the specific design and operational characteristics of the device in question.
