Leather tanning and finishing data for AI hide and finish records
EPA describes tanning and finishing as a manufacturing category with distinct process activities.
NAICS 316110 · Leather and Hide Tanning and Finishing
EPA describes tanning and finishing as a manufacturing category with distinct process activities. A document-and-image sample can focus on connecting a hide section to its recorded finish without exposing a proprietary treatment recipe. EPA leather tanning and finishing context
Photograph finished sample offcuts with original identifiers and create a fictional hide map, finishing ticket and inspection sheet. Split one hide into two finish orders. Ask which offcuts have a supported finish association. Add a sample whose reverse-side code is outside the first image, then provide a second view that resolves only that association. Similar surface color should not be enough to identify a finish order.
Annotate parent hide, section, finish reference, visible condition and source region. Hold out a new color family for evaluation. Score wrong-parent matches and unsupported process claims independently. A model can describe visible surface variation while leaving its cause unresolved when the records do not establish it.
Use cleared offcuts, self-authored forms and invented process references. Actual chemistry, customer finishes and supplier tracing records need separate permissions. A proposed licensing package should name the evidence-linking task and independent review. Confirm whether the buyer needs images, records or linked views before planning additional capture.

Original Fiund exercise
A visual observation stays with its mapped region
Owned finished offcuts stand in for regions of a fictional hide. The model resolves lot and region without inferring chemical treatment or material grade.
| Record | Source | What it records |
|---|---|---|
| D1 | Hide map | Hide H12 divided into back patch B and belly patch E. |
| D2 | Finishing ticket | H12-B assigned finish M; H12-E assigned finish N. |
| D3 | Offcut image | Tag H12-E, matte patch around a circled point. |
| D4 | Inspection sheet | Inspector observation about gloss references H12-B only. |
Question for the model
Which finish record goes with the photographed region?
Show the reference answer and checks
Link D3 to finish N through H12-E on D1 and D2. D4 records a different region of the same hide, so its gloss observation cannot replace the visible matte patch label for E. Neither record identifies a chemical cause for the appearance.
- Using the hide ID alone to join finish tickets
- Reading subjective gloss across uncontrolled photos as a lab measurement
Fields to preserve
- hide_region
- Keeps region-specific finishing and inspection distinct
- finish_ticket_ref
- Links only to the treatment record named for that region
- observation_method
- Separates visual description from measured gloss
Test another case
Show two regions in one photo and omit the dividing overlay; score the photo-level hide ID but leave the localized join unresolved.
Do not include tanning recipes, real supplier records or private inspection certificates.
