# Petroleum Import Supply Chain Monitoring

> The U.S. Customs and Border Protection (CBP) develops blockchain solutions to improve import traceability and prevent illegal trade practices. While a specific project for monitoring petroleum imports could not be verified, CBP already uses blockchain technology for verifying NAFTA and CAFTA certificates. These applications demonstrate the potential of blockchain technology to improve transparency and efficiency in customs clearance.

## Description

CBP and DHS are investigating blockchain as a tool to control crude oil imports and enforce trade sanctions. The fundamental issue: crude oil from sanctioned countries (Iran, Russia, Venezuela) is transshipped via third countries (Malaysia, UAE, Turkey) and declared as non-sanctioned oil with forged certificates of origin.

Transshipment fraud related to sanctions costs the US billions in lost enforcement. The US OFAC (Office of Foreign Assets Control) imposes fines of up to 1 billion USD for violations. Blockchain solution: producing countries register crude oil batches at extraction with GPS coordinates, extraction date and quality parameters on the blockchain; every ownership transfer and loading is documented; upon US import, CBP verifies the blockchain-secured chain of origin. Technically, combined IoT-blockchain approaches are necessary: sensors on the tanker continuously measure cargo temperature and quantity; GPS tracking documents the tanker route. Blockchainwelt reported on the CBP use for free trade generally as context. Ledger Insights analysed the CBP approach for IP protection as a structurally related model.

## Benefits

- Accelerated customs clearance processes reduce storage costs and delivery delays for importing companies.
- Increased product safety through better monitoring and authentication of imported goods.
- Drastic reduction of document fraud and illegal imports through immutable blockchain records.
- Significant efficiency gains in customs clearance through automation of recurring verification processes.
- Improved transparency and traceability in global supply chains strengthens the trust of all parties involved.
- Automation of routine tasks enables employees to focus on more value-adding analytical activities.

## Challenges

- Companies must invest in new systems and training to be compatible with blockchain-based customs processes.
- Integration of various systems and stakeholders along the entire supply chain requires significant coordination and standardisation.
- High implementation costs and technical complexity may exclude smaller players from the system.
- Employees require comprehensive training in blockchain technology and new digital workflows.

## Technology foundation

Blockchain technology offers an immutable and transparent record of all transactions in the supply chain, preventing fraud and manipulation. Permissioned blockchains are particularly suitable as they allow controlled access to sensitive trade data while providing the necessary transparency for authorities.
