4809.20.20.00 - Writing paper

HTS Code 4809.20.20.00 specifically classifies "Writing paper" within the broader category of carbon paper, self-copy paper, and other copying or transfer papers. This subcategory pertains to paper primarily intended for use in traditional writing instruments such as pens, pencils, and markers. It encompasses plain or lined paper designed for personal correspondence, note-taking, or general writing purposes, where the ink or graphite from the writing instrument directly transfers to the paper's surface.

Distinguishing this from its sibling category, 4809.20.40.00 ("Other"), is crucial. While 4809.20.20.00 is dedicated to paper used for direct inscription, the "Other" category would likely cover specialized transfer papers not falling under self-copying or direct writing applications, such as papers for heat transfer, stencil duplication, or potentially certain types of decorative transfer. The key differentiator lies in the primary intended function and the mechanism of image or information transfer.

As a leaf node, this HTS code does not have further subcategories. Therefore, classification under 4809.20.20.00 relies on confirming the paper's primary design and intended use for direct writing applications, distinct from more complex transfer or duplicating functions. Considerations for classification would include the paper's absorbency, surface treatment (or lack thereof), and common presentation in stationery or office supply formats suitable for handwritten communication.
