Additional Submission Guidance

Selecting the correct chain of custody form helps ensure your samples are routed to the appropriate testing process without delay. If multiple material types or test methods are required, separate forms may be needed to clearly define each request.

For larger or more complex projects, providing detailed project information and testing requirements can help streamline processing and improve turnaround times.

If you want a step-by-step overview of forms, uploads, and material-specific requirements, read our guide on how to submit soil and geosynthetic samples.

What Is a Chain of Custody Form?

A chain of custody (COC) form is used to document the transfer, handling, and testing requirements of samples submitted to the laboratory. It ensures that all materials are properly identified, tracked, and processed according to project specifications and testing standards.

The form includes important details such as sample identification, requested test methods, project information, and contact details. Providing complete and accurate information helps ensure that testing is performed correctly and that results are clearly associated with the submitted materials.
