8540.71.40.00 - Other

This HTS category, 8540.71.40.00, encompasses "Other" magnetrons. Magnetrons, as a broader class of microwave tubes, are devices that generate high-frequency electromagnetic waves, typically used in radar systems, industrial heating, and scientific applications. Within this specific subcategory, "Other" signifies magnetrons that do not fall under any more precisely defined classifications within the 8540.71 heading.

This category is distinguished from its sibling, 8540.71.20.00, by its intended application. While 8540.71.20.00 specifically covers magnetrons modified for use as parts of microwave ovens, this category 8540.71.40.00 covers all other magnetrons not designated for that particular purpose. Therefore, classification here depends on the absence of the specific modification and application described in the sibling category.

As a leaf node, this classification does not have further subcategories. Goods classified under 8540.71.40.00 are thus the final level of specificity for this particular type of magnetron within the HTS structure. Proper classification will rely on confirming the product is a magnetron, not specifically modified for microwave ovens, and fits within the general scope of microwave tubes covered by heading 8540.71.
