Traceability in the supply chain: Building trust and transparency from source to shelf

So, how do you meet this consumer demand? Build transparent and compliant supply chains that can track your product’s every step.

Supply chain traceability refers to the ability to track and document a product’s journey through every stage from raw materials to production, distribution, and final sale. It includes knowing:

• Where components originate

• Who handled them at each step

• How they were transported

• Whether quality, sustainability, or safety standards were met

This level of transparency ensures that businesses can verify authenticity, streamline recalls, demonstrate compliance, and build consumer trust.

From source to shelf, consumers want a story they can trust. Whether it’s a bar of chocolate, a skincare product, or a pair of sneakers, people increasingly want to know: Where did this come from? Was it made ethically? Is it safe to use? Supply chain traceability brings transparency to the products we buy, building trust and connection from the brand all the way to the customer.

But behind that consumer experience lies a business perspective. For B2B organizations, traceability is good for both customers and business. Here’s why it’s important: 

1. Proving authenticity and ethical sourcing
Consumers and regulators want assurance that goods are genuine and responsibly sourced. Traceability helps prove compliance with labor laws, environmental standards, and origin certifications.

2. Managing risk and enabling rapid recalls
If contamination or defects occur, traceable systems allow companies to act fast, isolating affected batches, minimizing harm, and maintaining brand reputation.

3. Enabling circular economy models
For businesses focused on sustainability, traceability allows better tracking of materials for recycling, reuse, or resale. It supports product passports and carbon footprint tracking.

4. Improving supply chain efficiency
With real-time insights into material movement and condition, companies can optimize inventory, reduce waste, and respond quicker to disruptions.

5. Meeting global regulations
Laws like the EU Digital Product Passport require traceability. Companies without proper systems risk fines, product seizures, or market bans.

Modern supply chains generate mountains of data. But without the right tools, it’s difficult to verify or share that information securely. This is where advanced technologies come in:

Blockchain for tamper-proof traceability

Blockchain ensures data integrity by creating a decentralized, immutable ledger of transactions. Once added, information cannot be altered, making it ideal for recording product origin, handoffs, and quality checks.

Multi-party computation (MPC) for secure collaboration

Multi-Party Computation (MPC) allows different stakeholders (suppliers, manufacturers, regulators) to analyze and collaborate on shared data without exposing sensitive inputs. It unlocks insights while preserving privacy and competitive advantage.

Digital product passports (DPPs)

Digital product passports store and share essential product lifecycle data from raw material sourcing to disposal. They support both compliance and consumer-facing transparency.

Achieving true visibility across complex, global supply chains is a critical requirement for compliance and resilience. Let's explore how leading sectors are leveraging these capabilities, often alongside privacy-enhancing technologies, to gain unprecedented clarity without compromising sensitive data.

Automotive industry
Original Equipment Manufacturers (OEMs) manage vast, multi-tiered supply chains where even a single faulty component can trigger major recalls or safety issues. Traceability allows them to track parts like microchips or brake systems across suppliers and verify that materials such as cobalt or lithium are ethically sourced and ESG-compliant. However, sharing this data across stakeholders often involves competitive or sensitive IP. That’s why traceability must also ensure data privacy, enabling insights to be shared, like part authenticity or handling conditions, without exposing proprietary details.

Food and agriculture
From farm to fork, traceability ensures the safety, origin, and quality of what we eat. Retailers and producers trace produce back to specific farms, validating freshness and certifications like organic or fair trade. When contamination occurs, traceable data helps quickly isolate affected batches. But food chains involve many actors (farmers, processors, logistics partners), each holding valuable data. A privacy-preserving system ensures critical safety data can be verified and acted upon without sharing sensitive operational or supplier information.

Pharmaceuticals
In drug supply chains, traceability is a matter of life and death. Regulations require companies to document every handoff to prevent counterfeit or compromised drugs from reaching patients. Monitoring conditions like temperature during transport helps ensure efficacy and safety. Yet, drug formulation, logistics routes, and storage protocols are highly confidential. A system that allows secure, verified traceability without revealing raw data is essential, especially in cross-border operations subject to strict privacy laws.

Fashion and textiles
Consumers increasingly demand transparency around how and where their clothes are made. Brands use traceability to confirm organic cotton sourcing, recycled inputs, and carbon-neutral production. But behind the scenes, supply chains are fragmented and global, involving small-scale producers, manufacturers, and certifiers. Verifying compliance without exposing proprietary supplier networks or trade secrets requires infrastructure that supports secure collaboration where only the required proof, not the full data, is shared.

In global supply chains, it is not enough to know where something is. You also need to know that you can trust the data behind. That’s where Partisia comes in.

We go beyond visibility to enable verifiable, privacy-preserving traceability. Our platform, powered by Multi-Party Computation (MPC) and blockchain, allows manufacturers, logistics providers, and regulators to collaborate without exposing sensitive operational data.

Take the automotive industry: A manufacturer and a logistics provider can jointly verify that a high-value component was transported within required shock and temperature thresholds without either side sharing full internal data. Only the critical insight is revealed, not the underlying metrics or systems.

This privacy-first architecture unlocks:

• Cross-organizational traceability without sacrificing competitive intelligence

• Immutable audit trails anchored on blockchain for provable compliance

• Secure data collaboration across borders, aligned with GDPR and global standards

• Condition and custody verification that scales across suppliers and lifecycle stages

With Partisia, you’ll be able to track your products in the supply chain without security risk. And with privacy-enhancing technologies like MPC and blockchain, traceability no longer means losing control over your data.
