The textile Digital Product Passport specification defines 49 data points across four categories. The critical operational detail is granularity: minimum granularity is the production batch, not the model — so producer, facility, and substances-of-concern data sit at batch level, while most product characteristics stay at model level.
The single most consequential design choice in the spec is granularity. Most brands’ PLM systems are organised at SKU or style (model) level, but the passport requires batch-level data for key fields. That mismatch is where the real work lies.
The batch-vs-model split
Batch level: producer, facility, substances of concern, and the mandatory batch ID. Model level: most general product characteristics.
The carrier is the easy 5%. The batch-level supplier data — often from Tier 2/3 suppliers with no digital infrastructure — is the other 95%.
