9005.10.00.40 - Other prism binoculars

This HTS classification, 9005.10.00.40, specifically covers "Other prism binoculars." These are optical instruments designed to provide magnified views of distant objects using a system of prisms and lenses, distinguishing them from telescopes which typically offer higher magnification. The "other" designation indicates that this category encompasses prism binoculars that do not fall under more specific sub-classifications.

It is crucial to differentiate this category from its sibling, 9005.10.00.20, which is exclusively for prism binoculars designed for use with infrared light. If a prism binocular's primary function or construction is not inherently tied to the detection or amplification of infrared radiation, it would generally be classified under 9005.10.00.40. The primary distinction lies in the intended spectral range of operation.

As 9005.10.00.40 is a leaf node, there are no further subcategories. Therefore, classification within this code relies on correctly identifying an item as a prism binocular and ensuring it does not meet the specific criteria for any other sibling category, particularly those related to specialized infrared applications. Common examples would include standard terrestrial and marine binoculars that utilize prisms for image erection and inversion.
