A combination filling-and-labeling machine is classified under 842230, which explicitly covers filling, closing, sealing, and labeling machinery together. If the machine's principal function is wrapping or packing rather than filling, it may fall under 842240. For highly integrated lines performing multiple functions, the principal function or GRI 3(c) applies, and a binding ruling may be warranted.

Yes — household dishwashing machines are classified under 842211, while commercial and industrial dishwashers fall under 842219. The distinction generally follows capacity, construction, and intended use: machines designed for domestic kitchens go under 842211, while those built for restaurant, institutional, or industrial throughput go under 842219. CBP has issued rulings on borderline units, so importers of high-capacity 'prosumer' machines should verify the correct subheading.
