Sample Return Policy and Guidelines

Sample Return Policy

The process of reducing carbonaceous material to carbon for AMS measurement is necessarily destructive of the original sample. AMS technology, however, requires only a small quantity of material in order to obtain a date. Sample material may remain following analysis.

Sample Return

Please indicate on your Submission Form and via email, whether you would like your samples returned. Original sample material will be returned to the submitter's address, unless otherwise indicated.

Domestic Returns

A US $15.00 fee will be added to the final invoice for domestic FedEx Ground shipping, weighing less than 2 lbs. Additional costs may be applied according to package weight or shipping priority.

We also accept prepaid packaging.

Samples are returned within 60 days, following the report of results, unless otherwise requested.

International Returns

We accept prepaid packaging, when accompanied by the necessary paperwork, and will arrange pickup with any of the following couriers: FedEx, UPS, DHL.
