The item at issue is a metal alloy tipped pencil. It has the visual presence of a pencil without the core material running through a shaft. There is a removable metal alloy tip comprised of 80% lead, 10% tin, and 10% bismuth, that attaches to a barrel. As one writes, tiny amounts of metal are deposited from the tip on the page and make markings. These pencils are distinguishable from mechanical pencils of heading 9608 in that they do not have a mechanical action, e.g., screwing, spring or sliding mechanism, for extending and retracting the lead by propelling or sliding the lead out of its housing so that it can be functional.
