Certified partners

This is the registry TRADEMARK.md points to: the authoritative list of who is allowed to put the TigerTag mark on a product.

If you are holding a spool or a box carrying the TigerTag logo, the maker should be on this page. If it isn’t, the mark is not authorized — the logo may be shown freely in an app, in documentation or in a store listing to say “this works with TigerTag”, but never on a chip, a carrier, a spool or its packaging.

What certification actually is

Section titled “What certification actually is”

An audit, granted by TigerSystem — of the product and of the process — and then a trademark licence. It is not paperwork and it is not automatic: it is what makes the promise on the box true.

For a filament manufacturer it means one thing in particular: they are given the signing tools. Their spools can carry a TigerTag+ Certified — a catalogue identity plus an origin signature, issued under a private key TigerTag holds. Anyone can verify that signature, offline, on their own phone, with no account. A cloned tag fails the check.

Certification is never required to use the protocol. Implementing it, building on it, and saying “compatible with TigerTag” stay free, unaudited and self-declared — see third-party hardware for what that looks like in practice.

Filament manufacturers

Section titled “Filament manufacturers”

The tiers describe how far the protocol is deployed inside the partner’s production, not how good the partner is.

Partner Tier Deployment
Rosa3D Platinum — integrated across the whole production line TigerTag+ on 100 % of its 1 kg spool production. The first filament manufacturer to integrate the protocol into its factory lines, with more than 250 000 tagged spools produced since. Its ReFills carry two chips, recoverable and reusable once the spool is finished.
R3D Gold — large-scale production, public commitment Large-scale deployment across its European filament production, after more than a year of work with the TigerTag team. Its chips are left unlocked, so the data can be erased and reprogrammed.
eSun Gold Officially integrated, rolling out as a pilot programme in the French market, with stated plans to expand across Europe and then globally. That is their own description of the scope.
Sunlu Silver — integrated on request Tags spools with TigerTag+ on request.
Landu Silver Tags spools with TigerTag+ on request.
JamgHE Silver Tags spools with TigerTag+ on request.

Retail boxes carrying the mark — bought in a shop, not staged.

Integration in progress

Section titled “Integration in progress”

Nanovia and Filforme are currently integrating TigerTag+. They are not yet shipping, and are listed here because they are in the programme — not to imply availability.

Checking a mark yourself

Section titled “Checking a mark yourself”

Two independent checks, and neither needs us:

  • This page. The maker of a chip, carrier, spool or box bearing the mark should appear above.
  • The signature. A TigerTag+ Certified carries an origin signature you can verify with any reader, offline and without an account — the public keys are published. See TigerTag+.

Becoming certified

Section titled “Becoming certified”

If you make filament, resin, inlays, carriers, a device or an application and want to be listed here, the process is an audit followed by a trademark licence. It is a paid service, on the model the Connectivity Standards Alliance uses for Zigbee and Matter.
