CBP Isotopic Testing Guidance

U.S. Customs and Border Protection's Forced Labor Division has published a general guide on isotopic testing and supply chain traceability.

While CBP does not endorse any specific laboratory, CertainT Isotope Testing meets CBP's guidance. Our isotopic testing partner, Isotech Labs, is ISO 17025 accredited, conducts proficiency testing, and conducts statistical modeling as part of our method of analysis.

CBP encourages the trade community to utilize origin verification testing, including isotopic testing, to better understand their supply chains, demonstrate due diligence, and assist with determining the source of raw materials in final products. Isotopic testing represents an important development in global supply chain traceability, but relying entirely on this tool for supply chain traceability is neither feasible nor effective. For optimal results, isotopic testing should be considered one component of an importer and manufacturer’s supply chain tracing and risk management efforts in conjunction with other tools such as DNA molecular tagging.

The strength of CertainT® isotopic analysis lies in its ability to provide evidence of the physical product’s origin at multiple checkpoints in the supply chain.

About CertainT Testing Partners

TÜV-SÜD

Applied DNA began working with TÜV SÜD AMERICA in March 2023

The CertainT platform is a complement to TÜV SÜD's traceability services, allowing clients to access a portfolio of services including factory audits, supply chain mapping, product verification at various supply chain entities, and cotton source verification.

Isotech

Applied DNA uses Isotech's isotopic analysis assay to forensically determine cotton fiber and fabric origin

The addition of isotopic analysis (IA) to the CertainT platform yields a continuity of data across the entirety of a natural fiber-based value chain, from source to finished goods. This data helps ensure adherence to social (avoidance of products made with forced or slave labor) and environmental practices (sustainable, organic) aligned with regulatory and consumer expectation.
