01
State what the reference sample is for
VIN EXPRESS can procure U.S. reference samples and consolidate them for shipment to China to support reverse engineering and forward product development. Its procurement team coordinates the physical supply. Customers should identify the product and comparison question before purchase.
Record the part number, brand, variant, quantity, seller reference and required evaluation condition. Keep purchase and arrival photographs. A market reference is not automatically an approved production sample, and receipt in China does not establish engineering acceptance.
02
Create one approved baseline record
A drawing named “final” is difficult to control across suppliers and teams. Assign a revision linked to the physical sample, specifications and decision record. Identify materials, dimensions, finishes, interfaces or functions needing review, and who judges the evidence.
Adapt this suggested approval worksheet to your product and project. It is not a prescribed automotive approval standard or a replacement for the customer’s engineering process.
| Suggested record field | Information to enter | Owner to identify |
|---|---|---|
| Product and sample identity | Part number, variant and individual sample reference | Customer product owner |
| Drawing baseline | Revision, file date and linked specification list | Design authority |
| Approved physical sample | Sample reference, photographs and approval scope | Authorized approver |
| Acceptance evidence | Criteria, method, results and unresolved points | Named reviewer or test provider |
| Production release | Approved revision, conditions, quantity or lot applicability | Customer’s release authority |
| Changes | Reason, affected files, effective point and decision | Change owner and approver |
03
Turn observations into explicit requirements
Photographs and measurements describe observations. A production brief needs requirements that can be interpreted by the manufacturer and checked by the designated reviewer. Clarify units, reference features, tolerances, material requirements, surface finish and the intended interfaces where those details matter to the product.
Give the supplier a controlled set of files and a place to raise questions. Resolve conflicting dimensions, unclear notes and missing information before treating the package as ready for production. Where an assessment or test is needed, name the responsible party and method; logistics coordination does not itself validate performance or durability.
04
Make approval specific and attributable
An approval identifies the reviewed item, version, evidence and decision-maker. Record whether it is approved, approved with conditions, held for further work or superseded. These are suggested working statuses; agree terminology and authority with the customer.
If appearance is accepted but a fit check or functional assessment remains open, record that distinction. Do not let a general “looks good” message become an unrestricted production release. Identify the open question, who must answer it and whether it prevents manufacturing, shipment or another project stage.
05
Keep changes connected to their effect
When a dimension, component, material or packaging design changes, create a change reference and describe the reason. List the affected drawings, specifications, samples and instructions. State when the change applies: for example, to a named production lot or to orders released after an agreed point.
Retain the previous record while making the current approved set unmistakable. Ask the relevant parties to confirm they received the update, and agree what happens to stock or samples made to the earlier version. A revised file in a shared folder is not enough to show that a supplier accepted the change.
06
Carry the decision into receiving and packaging
Before production stock moves, confirm which references should appear on the packing list and receiving instructions. Distinguish a receipt count and visible-condition record from an engineering acceptance result. VIN EXPRESS manages each product with RFID; that identity should connect to the agreed product and stock records without implying that every receipt has passed a functional test.
VIN EXPRESS provides packaging design and has professional repair and procurement teams. Define their work alongside customer approval responsibilities. Hand over the reference-sample list, current files, decisions and receiving criteria, keeping the physical product and approved description connected.
VIN EXPRESS / The planning takeaway
Suggested sample-to-production handoff checklist
- Give the reference purchase a product identity and a clear evaluation purpose.
- Assign references to physical samples and retain condition photographs.
- Identify the drawing revision and the complete specification set.
- Name acceptance criteria, evidence requirements and responsible reviewers.
- Record the approver, decision scope and any unresolved conditions.
- Document changes, affected versions and their effective production point.
- Align production, packaging and receiving references before shipment.

The 1999 circuit-board case, section 5.2 and Appendix C, illustrates corrected CAD files, revision identification and an approved engineering change record. It is historical evidence for document control, not a current automotive PPAP or sample-approval requirement. This article’s worksheet is a VIN EXPRESS planning recommendation.
