The global trend towards greater supply chain transparency: Why is traceability becoming a procurement barrier?

How can enterprises establish a supply chain traceability system from raw materials to finished products?

Traceability is evolving from simply "finding the cause after a quality problem occurs" to a fundamental capability for procurement, compliance, and supply chain risk management.

The EU's Digital Product Passport (DPP) system is driving further digitization of product information. In July 2026, the EU DPP Registry will officially launch; this system will become a crucial infrastructure for the Digital Product Passport framework.

The long-term trend behind this is:

Products not only need to prove they are "qualified," but also "where they came from, how they were produced, and what happened."

I. True Traceability is Not Just a QR Code

A QR code is merely an entry point.

True traceability should establish:

Raw Materials → Supplier → Production Batch → Process → Inspection → Finished Product → Customer

If scanning a QR code only reveals:

• Company Profile;

• Product Images;

• Marketing Page,

it does not prove supply chain traceability.

II. Buyers Most Need to Track Four Types of Information

Material

• Raw material supplier;

• Material grade;

• Batch;

• Testing certificate. ### Production

• Production Date;

• Equipment;

• Process Parameters;

• Shift.

Quality

• First Inspection;

• In-Process Inspection;

• Final Inspection;

• Anomaly Records.

Product

• SKU;

• Serial Number;

• BOM Version;

• Packaging Version.

III. Which Products Require Deep Traceability Most?

The following products typically have higher priority:

• Automotive Parts;

• Medical Related Products;

• Batteries;

• Electronics;

• Aerospace;

• Safety-Critical Industrial Parts.

Low-value, general-purpose, and low-risk products do not require the same complex traceability system.

Traceability depth should match product risk.

IV. Stellar Five-Level Traceability Model

Level 1｜Order Traceability: Knowing which batch of goods was sent to which customer.

Level 2｜Batch Traceability: Being able to trace back to the production batch. ### Level 3 | Material Traceability: Enables tracing key materials.

Level 4 | Process Traceability: Connects process and quality data.

Level 5 | Lifecycle Traceability: Digitally connects design, production, logistics, maintenance, and product lifecycle data.

V. Don't ask "Do you have a system?" during procurement audits.

A more effective testing method:

Randomly select a finished product number and ask the supplier to answer the following questions in reverse:

1. When was it produced?

2. Which production line?

3. Which batch of materials?

4. Where did the materials come from?

5. What inspections were performed?

6. Were any anomalies observed?

7. Where did the same batch of products go?

A traceability system is truly valuable only if it can be quickly traced back.

Core Decision-Making Dimensions

| Dimension | Key Points for Procurement Judgment |

| --- | --- |

| Capabilities | Does the supplier truly match product and process requirements?

| Evidence | Are there verifiable data, records, or case studies?

| Risk | Are there recovery and alternative solutions in case of anomalies?

Supply chain transparency does not mean disclosing all trade secrets.

The real goal is:

Within the authorized scope, make key product information verifiable, traceable, and explainable.

In the future, suppliers who can prove their production process will be more credible than those who can only show final test reports.
