Hand-operated devices for impressing dates, sequential numbers, seals, or embossed labels — including self-inking stamps, daters, and hand-held label embossers — serve critical document-control and authentication functions across logistics, legal, and retail sectors. The heading also captures hand printing sets (e.g., rubber-stamp kits), distinguishing them from automated or machine-driven marking equipment. Products that incorporate electronic or motorized actuation mechanisms are generally reclassified outside this heading, so the 'hand-operated' criterion is the pivotal classification test.
