Industrial-scale machinery for preparing fruits, nuts, or vegetables for food manufacturing falls under 843860 within this heading. Equipment used in the field or at the farm level — such as harvesters or sorting equipment at the agricultural stage — classifies under the agricultural machinery headings. The industrial versus agricultural context is the deciding factor.

Classification of a multi-function production line follows the machine's principal function. If the brewing function is primary, the unit would generally fall under 843840 (brewery machinery). Packaging equipment that is separately imported and not integral to the brewing process may classify under the packaging machinery heading. A binding ruling from CBP is advisable for integrated systems where the principal function is not clear-cut.
