Our laboratories are equipped with the latest analytical equipment and we are therefore able to provide highly detailed analytical reports.

We also work closely with official government laboratories and independent surveyors to supply certificates when required.

Over the years, we have been asked to supply a huge variety of certificates and documents and we are well versed in issuing or obtaining the appropriate documentation.

Most frequently, we provide:

  • Certificate of Analysis
  • Certificate of Origin
  • Certificate of Cleanliness (packaging)
  • GMO Certificate
  • Allergy Certificate

We can also provide notarised and legalised documentation.
