9608.60.00.00 - Refills for ball point pens, comprising the ball point and ink reservoir

HTS Code 9608.60.00.00 specifically classifies refills for ballpoint pens. These refills are characterized by their inclusion of both the ballpoint mechanism and the ink reservoir, representing a self-contained unit designed to be inserted into a pen barrel. The primary function of these articles is to provide the writing component and ink supply for a ballpoint pen.

This category is distinct from its sibling categories, most notably HTS 9608.10.00.00, which covers complete ballpoint pens ready for use. While refills are a component of a ballpoint pen, they are not the finished product. Unlike other pen types classified under 9608.20.00.00 (felt-tipped markers) or 9608.30.00 (fountain pens), the defining feature of 9608.60.00.00 is the ballpoint writing system combined with an integrated ink supply.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification decisions within 9608.60.00.00 will rely on confirming that the article comprises both the ballpoint tip and the ink reservoir, serving as a replacement part for a ballpoint pen. Examples include individual ink cartridges with a rollerball tip already attached, often sold in multi-packs for retail.
