Incoming Natural Corks - Scores Less than 2ppt

CQC Audit Results - March 2023

Current Results from Screening of Incoming Cork Shipments Show 99% with Releasable TCA below 1ppt (ng/L).

The CQC screening protocol receives data with minimum reporting limit of “<1.0ppt”. The group has agreed to treat results below the MRL as “0.5ppt” for statistical purposes. Under this assumption, the group’s statistical records cannot improve below 0.5ppt.

Based on these screening results, approximately 1% of incoming natural cork lots were rejected by the CQC members prior to acceptance into inventory.
