In order to be able to test and certify products, industries and processes, certain definitions and specifications are required. These specifications or guidelines, also called "standards", are specified by the respective accrediting body. HQC is subject to clearly defined Standard Operation Procedures (SOPs) during the certification process. These SOPs are used for the final product release.

​

Moreover, HQC not only complies with these halal standards, but also works according to quality specifications such as the standards of the International Organisation for Standardisation (ISO) and H(H)ACCP (Hazard Analysis and Critical Control Points).

HQC Europe as well as HQC Germany list the halal standards on their official website, which have been set by different governmental authorities and institutions. These are divided into
