Yes, you can submit a product tag as a specimen of use for physical goods. Before you do, make sure the tag meets these requirements to avoid a refusal:
- The mark in your trademark application must be displayed prominently on the tag, so consumers can clearly associate the brand with the product the tag is attached to.
- The mark must match the version originally filed in the trademark application.
- The specimen must be legible.
- The tag must be from actual commerce, not a mock-up or prototype. It also cannot be digitally altered and must be a real-life photo.
