# Blockchain-based Certificate Verification at U.S. Customs and Border Protection

> The U.S. Customs and Border Protection (CBP) uses blockchain technology to verify NAFTA and CAFTA certificates to validate the origin of products. The technology enables tamper-proof documentation and tracking of trade agreement certificates in the international supply chain. Through the use of blockchain, customs officials can more quickly and securely verify whether imported goods actually meet the requirements for trade agreements.

## Description

Government authorities see blockchain as a tool to improve food safety for imports. CBP (US Customs and Border Protection) and FDA (Food and Drug Administration) have complementary interests: CBP controls imports at the border, FDA regulates food safety and traceability.

FSMA (FDA Food Safety Modernization Act, 2011, fully in force since 2023) obliges importers to ensure seamless traceability of high-risk foods. In the event of an E. coli outbreak caused by imported spinach, all affected batches must be identified within hours. Blockchain approach: All food imports are recorded with blockchain-secured proof of origin (country of origin, producer, harvest date, transport route); CBP officers can immediately check the complete documentation chain at the border; suspicious shipments are blocked, non-suspicious ones released faster. Open Logistics Foundation analysed blockchain as a modernisation tool for customs processes overall. Blockchainwelt documented CBP activities in free trade and blockchain. The Walmart/IBM Food Trust model (mango traceability from 6 days to 2.2 seconds) demonstrates the achievable speed for government controls.

## Benefits

- Companies save time and costs through faster and automated compliance checks in international trade transactions.
- Blockchain technology prevents manipulation of certificates of origin and thus significantly reduces trade fraud.
- Automated certificate checks speed up customs clearance processes and reduce waiting times at borders.
- All authorised actors have simultaneous access to the same verified data, increasing transparency in international trade.
- Employees in customs authorities can shift from routine tasks to strategically more important control and analysis activities.

## Challenges

- Companies must adapt their existing documentation processes and IT systems to the new blockchain requirements.
- Integrating the blockchain platform with existing legacy systems of various customs authorities requires significant technical effort.
- Acceptance and uniform use of the new technology by all international trade partners poses an organisational challenge.
- Employees require comprehensive training on handling the new blockchain technology and its integration into existing workflows.

## Technology foundation

The solution is based on a blockchain platform that enables immutable and transparently traceable documentation of certificates. Blockchain is particularly suitable for this use case as it prevents manipulation and grants all authorised parties simultaneous access to the same verified data.
