Quality Assurance

Your finished product is only as good as your testing capabilities can prove it to be.


Our full-service CGMP manufacturing facility is certified under 21 CFR Part III and is NSF CGMP certified. We are an FDA registered facility and are certified by the State of Washington for dietary supplement manufacturing. We would also like to note that our manufacturing facility has been approved in over ten countries for dietary supplement exporting.


Our hazard analysis testing is established through the use of an NSF-designed critical control point program. Since every raw material has a unique microbial or environmental adulteration hazard, each material also has a predetermined testing protocol suited to its own risk level. These mitigations also include at least one upstream and one downstream protection to prevent adulterants from entering the processing chain. These mitigations are ingredient-specific and are added to each ingredient specification sheet, assuring that each time any ingredient is received, it is reviewed and tested for its unique hazard(s). Regardless of how low an ingredient’s risk level is determined to be, every raw material is tested using USP- and/ or AHPA- recommended standards.


We conduct 100% in-house testing of identification using a variety of means, including near-infrared spectroscopy, ICP-MS, and HPLC. Our reference standards are verified by a select few third-party laboratories that hold the ISO 17025 accreditation, certifying their validity. Our in-house reference standard library houses over 1,000 raw materials for quick and accurate results.

Environmental Monitoring

Environmental testing for microbiological bioburden hazards is an integral part of the testing program designed by First Priority Manufacturing. Microbial adulterants introduced during holding or processing are monitored utilizing USP Method 1116 for the continued evaluation of microbial limits in controlled areas.


We conduct ELISA allergen testing in-house for all eight major allergens and have the capability to test for hundreds more through our third-party laboratories. Allergen testing gives you and your customers the comfort of knowing that the products we provide are safe for everyone.


Ensuring your finished product meets its label’s claim is one of the most important quality measures in nutritional supplement manufacturing. Our quality team has multiple checkpoints and testing methods to ensure your products meet all claims. Need a COA for your finished product to comply with Amazon or other selling agencies? Ask your customer service representative today and our quality team will happily provide you with one.

Third-Party Laboratories

We have hand-selected our primary third-party laboratory, which holds the coveted international ISO 17025 certificate. We also utilize the expertise of multiple other third-party laboratories as needed. Why is this a priority? Verification that our in-house laboratory is audited is integral to our integrity. We do not just rely on our own laboratory, at times a third-party laboratories expertise is important for these audits.

We are continually advancing our robust testing capabilities to offer you the highest standard of assurance, that exceeds cGMP and the FDA requirements.

SPS 4 Autosampler
The SPS 4 is a next-generation, high-performance autosampler for atomic spectroscopy applications. Designed to meet the needs of high-throughput laboratories requiring a fast, high-capacity (up to 360 samples or 768 microtiter wells), reliable autosampler, it is also small, quiet, easy-to-use and affordable. The SPS 4 is suitable for ultra-trace analysis by ICP-MS and rugged and robust enough for FAAS, MP-AES, and ICP-OES users. Built around an innovative gantry design that supports the mechanical components between two rigid pillars, the SPS 4 provides improved accuracy and precision, high speed, ease of access, and corrosion resistance – all within a footprint that is nearly 40% smaller than other autosamplers in its class.
