We
always attach most importance to the quality of our products, from
each batch of raw materials to each batch of finished products.
For raw material, we carefully investigate
and select the supplier of every kind of raw materials. We evaluate
our suppliers every year by visiting every supplier, inspecting
their manufacturing facilities and checking if they conform to various
quality assurance systems. For each batch of raw material we require
original certificate of analysis and additional tests will be conducted
in our own laboratory before using the related material. We
will strictly mix the ingredients according to the formulas with
state-of- the- art processing. For product
test, we have effective test instruments to meet our needs, such
as HPLC, UV, TPC and AA test instruments. We also have our in-house
test methods.
