Customs Laboratory Services LLC (CLS) has the expertise, equipment and experience to run all "U.S. Customs & Border Protection (CBP) " lab tests on all types of imported footwear, handbags, jackets and anoraks, coated or laminated textile fabrics, etc. For samples requiring highly specialized analytical instrumentation, CLS works closely with a number of university and commercial labs to provide you with an accurate, HTS-responsive lab analysis in the shortest possible turnaround time and at the lowest price.

For all lab analyses, CLS provides a written lab report that describes the sample, names the analysis methods used and presents the test results clearly and concisely. If appropriate, our lab report will also include our opinion as to the item's HTS classification and rate of duty.

CLS has two levels of service: Standard Service, which has a turnaround time of two to three weeks, and Priority Service, which has a turnaround time of three business days and for which a surcharge applies.
