8436.91.00.40 - Of poultry incubators and brooders

This HTS category, 8436.91.00.40, specifically covers parts and accessories designed for use with poultry incubators and brooders. This includes components such as heating elements, thermostats, egg turning mechanisms, ventilation fans, and internal racking or shelving systems that are integral to the functioning of these specialized machines. The primary purpose of these parts is to facilitate the hatching of poultry eggs or the care of young chicks by maintaining controlled environmental conditions like temperature, humidity, and air circulation.

Distinguishing this category from its sibling, 8436.91.00.80 (Other parts), is crucial. While the "Other" category would encompass parts for general poultry-keeping machinery not specifically related to incubation or brooding, 8436.91.00.40 is narrowly focused on the components of equipment designed for the controlled artificial incubation and rearing of poultry from egg to early development stages. For instance, a part for a poultry feeder or a manure cleaner would fall under the "Other" category, whereas a heating element for an incubator belongs here.

As a leaf node in the HTS classification, there are no further subcategories under 8436.91.00.40. Therefore, classification within this category relies on confirming that the part in question is exclusively or primarily intended for use in poultry incubators and brooders, as defined by their function in controlled hatching and early rearing processes. The emphasis is on the specific application and design of the part in relation to these specialized poultry machines.
