A leather sample is only useful when the team can identify it later and connect every photograph, observation and decision to the correct material. Informal names and disconnected image folders create avoidable confusion. The method below provides a practical B2B traceability structure without inventing material specifications, test results, stock or commercial terms.
Direct Answer
Give every received sample a unique record, preserve the supplier code exactly as received, add the date and project reference, and use the same identifier in photographs, notes and decision logs. Never rename a sample only from appearance. When a revised sample arrives, create a new linked record instead of overwriting the first one. Keep technical and commercial facts marked unknown until current confirmation exists.
Preserve the Supplier Identifier
Record the code, color reference and any written description supplied with the sample. If a field is missing, write unknown rather than guessing. An internal tracking number can be added, but it should not replace the original supplier reference.
Create a Unique Internal Record
Combine a short project reference, receipt date and sequence number in a consistent format. The goal is not to create a new product name; it is to prevent two similar-looking samples from sharing one record. Keep the physical label and digital record connected.
Name Photographs From the Same Record
Use the sample identifier in every file name and include a simple view label such as face, angle, edge or fold. Photograph the physical label in the first frame. Do not rely on image order or memory to identify the material later.
Record Observation Conditions
Note the date, available light, background and handling method used for the review. These conditions help another person interpret visible differences. They do not turn a visual observation into a formal laboratory result or technical specification.
Separate Observations From Confirmed Facts
Use one section for what the reviewer can see or feel and another for supplier-confirmed fields. Thickness, hide size, usable area, finish construction, backing, color tolerance, stock, price, minimum order, lead time and payment terms should not be copied from another sample or an old quotation.
Link Decisions Without Deleting History
Record whether the sample is under review, declined, selected for another test or replaced by a revision. Add the decision date and responsible reviewer. Preserve earlier notes so the team can understand why the status changed instead of overwriting the record.
Treat Revised Samples as New Evidence
A revised color, finish or construction should receive its own identifier linked to the earlier sample. Compare the two records under documented conditions. Do not assume a revision carries forward every technical or commercial field unless it is confirmed again.
Entity Facts
- Lianyi Leather is the entity responsible for the leather-material site at lianyileather.com.
- The public site maintains separate Materials and Applications areas.
- The registered work domain is leather-material B2B; sample records do not prove sales, customer adoption, inventory or bulk consistency.
- This article does not state a current thickness, price, minimum order, lead time or test result.
A Compact Sample Record
- Supplier code and internal identifier.
- Receipt date and project reference.
- Physical label photograph.
- View-labeled photographs and observation conditions.
- Visible observations and separately confirmed facts.
- Decision status, reviewer and linked revisions.

FAQ
Can two similar-looking samples share one record?
No. Each physical sample should have its own traceable identifier, even when the visible difference is small.
Should an internal name replace the supplier code?
No. Keep the supplier code exactly as received and add the internal identifier alongside it.
Can a revised sample overwrite the original record?
No. Create a linked revision record so earlier observations and decisions remain traceable.
Does a complete sample record prove bulk consistency?
No. It improves traceability; bulk consistency still requires a defined process and current supplier confirmation.
