Leather vs synthetic leather identification
A practical guide to leather vs synthetic leather identification: what to check on site, what a photograph cannot establish, and what to write in your purchase specification.
Leather versus synthetic leather is the single most common material dispute between overseas buyers and Chinese factories, and it is also the easiest to settle without a laboratory — provided someone knows what to look for.
The cross-section test
On an unwrapped or partially exposed edge — under the seat, at a seam allowance, at the back of a panel — the cross-section is visible.
| Observation | Genuine leather | Synthetic |
|---|---|---|
| Structure | Dense fibre bundle, suede-like nap visible on the underside | Woven or non-woven fabric base with a polymer coating |
| Edge | Rawhide or split edge that shows fibrous structure | Cut polymer edge, often with a fabric layer visible |
| Thickness variation | Uneven, follows the hide | Even, machine-cut |
| Surface | Fine wrinkles that change with pressure; pores of varying size | Embossed pattern that does not follow the underlying structure |
Secondary checks
- Water drop. Genuine leather absorbs slowly at a blot; PU-coated synthetic beads on the surface.
- Odour. Genuine hide has a characteristic smell. Synthetic has a chemical one.
- Label. A consistent, legally required description should be present. "Leather" and "leatherette" mean different things in most markets.
sofa verification includes the cross-section check at full verification.
What cannot be determined on site
Fibre composition and any chemical analysis. Where a contract specifies a composition, that requires a laboratory report — and your responsibility is to check that the report covers the batch you are buying, not the batch the factory tested last year.
This distinction is the point of sofa verification: the report records what was checked against your documents, and what was outside the scope of an on-site visit.
Regulatory note
Composition labelling requirements differ by market and have tightened in the EU and several US states. If you sell into those markets, state the destination in your purchase specification so the check is done against the right standard.
Common questions
What should my purchase specification contain?
Model and quantity, dimensions with tolerance, materials named rather than described generically, colour standard with a grey scale value, and any standard the goods must meet.
How early should verification happen before shipment?
After production is substantially complete but before the container is sealed. Earlier and there is nothing to inspect; later and the remedy is to unload in China rather than in your own country.
What does AQL mean in furniture inspection?
AQL is the Acceptable Quality Limit under ISO 2859-1 — the quality threshold used to accept or reject a sampled lot. It is an input to a decision, not a statement about how good the goods are.
