Quality Supreme Principle

It is ROCCA’s basic principle to supply customers only with qualified products from Quality Assured production lines and consistent raw material sources.

Besides manufacturing quality control system,  ROCCA regularly and independently re-inspects our factories’ production lines , packing rooms, warehouses and quality control center, to make sure every factory is truly qualified with regard to regular production order and good sanitary conditions, etc .
Afterwards we focus on factories testing methods and analytical instruments and we make sure that these testing processes meet international legislations such as FCC, BP, USP, NF, etc.
Finally we regularly draw samples from different batches and test it in an independent laboratory to verify the factories’ daily test results as well as the consistency of the quality, so to ensure ROCCA’s Quality Supreme Principle is upheld.
Rocca will keep on testing the products against orders and keep samples of every batch from delivered cargo as full batch traceability so that we could ensure good quality control on each order.
