8470.21.00.00 - Incorporating a printing device

This HTS category, 8470.21.00.00, specifically covers electronic calculating machines that **incorporate a printing device**. These machines function as calculating devices but have the added capability of producing a physical record of the calculations performed. Examples include electronic calculators with integrated receipt printers or devices that print transaction summaries for accounting purposes. The key defining characteristic is the presence of a printing mechanism directly integrated into the electronic calculating machine.

This category is distinguished from its sibling, 8470.29.00.00 ("Other"), by this specific feature. While both fall under electronic calculating machines, 8470.21.00.00 is for those with printing capabilities, whereas 8470.29.00.00 encompasses all other electronic calculating machines that do not have this integrated printing function, such as basic desk calculators without printers or pocket calculators. The presence or absence of an integrated printing device is the sole criterion for differentiation at this level.

As this is a leaf node within the HTS structure, there are no further subcategories branching from 8470.21.00.00. Therefore, the classification is complete at this point, with the defining characteristic being the incorporation of a printing device within an electronic calculating machine.
