All products are subject to rigid J.H. Baxter Quality Assurance Procedures and tested for specification compliance.
Most pressure treated wood products are third (3rd) party inspected and certified.
Third party inspection agencies are accredited and audited by the American Lumber Standard

J.H. Baxter & Co. operates its own on-site Quality Assurance Laboratory to provide prompt analytical results. After treating, units of material from each treating charges are checked for penetration and retention. Industry standards or customer specifications are used as the minimum basis for acceptance. Baxter's personalized customer service provides added benefits and avoids shipping delays. With an on-site QC Lab, treating result confirmation is usually made the same day.
Lab technicians perform elemental analyses using a Twin-X x-ray fluorescence (XRF) spectrometer as well as other physical and chemical testing of our products as part of its quality control procedures. We are dedicated to making continual improvements in our operations using the principles of statistical process control and lean manufacturing.
Baxter maintains high quality control standards that meet or exceed the American Wood Protection Association.
In addition, independent inspection agencies frequent our facilities to provide a third party overview of our
quality control samples, equipment and product treating standards.
