8436.91.00 - Of poultry-keeping machinery or poultry incubators and brooders

This HTS category, 8436.91.00, specifically encompasses parts designed for machinery used in poultry-keeping or for poultry incubators and brooders. These are components that, when assembled, form integral elements of equipment dedicated to the husbandry of fowl, including the artificial incubation and rearing of chicks. Examples might include specialized heating elements for brooders, thermostat controls for incubators, or structural components of automated feeding or watering systems intended for poultry.

This classification is distinct from its sibling category, 8436.99.00, which covers parts for other types of agricultural, horticultural, forestry, or apicultural machinery. While both fall under the broader umbrella of machinery parts, 8436.91.00 is narrowly focused on the specific applications of poultry management and hatching. Therefore, a part's intended use and its direct contribution to the functioning of poultry-specific equipment are key differentiating factors for classification.

Further refinement within this category is provided by its subcategories. 8436.91.00.40 is designated for parts specifically relating to poultry incubators and brooders, highlighting the equipment used for the initial stages of poultry life. Conversely, 8436.91.00.80 covers other parts used in general poultry-keeping machinery, such as those involved in feeding, watering, or waste removal systems that do not solely pertain to incubation or brooding processes. This subdivision allows for more precise classification based on the specific function of the poultry-related machinery the part supports.
