In-House Lab

Our in-house lab in Shanghai is currently testing mesh size,microbiology and density as an initial step, and plan to test heavy metals in a few months. In 2013, DNP will expand the testing items to Assay, identification, and loss on drying as the next step. Eventually, DNP will have full control over the quality of products by testing a majority of the items listed on the COA.

3rd Party Lab Testing Program

DNP not only tests the products with its in-house lab, but also sends them to a 3rd party lab to verify quality with a second round of testing. For new product and new manufacturer origin, DNP will have the lab report before product is put into market. For regular product, DNP also has a testing program for quarterly or half yearly reviews.

Origin Tracking Systems

Sample of “Customer Approved Material Origin Report”

With the execution of cGMP, consistent quality is as important as maintaining good quality. Part of our quality control program includes keeping records of all approved manufacturer origins for our customers. We put notes for the preferred origins per our customer’s request or we keep records of the sample origin that is approved by the customer. We implement this process to help our customers with their compliance in cGMP.  


Customized Shipping System

Sample of Shipping Instructions

At DNP we pride ourselves in providing the fastest, most accurate shipments as possible. Any order placed before 2pm will be shipped out on the same day. We are even more proud to provide 100% customized shipping. Many other distributors use public warehouses and are unable to provide customized shipping. Some distributors who have their own warehouses will not accommodate their customers in this way either. Even with 10,000+ annual shipments, we never compromise any request of our customers. We carefully record all shipping instructions stated on each purchase order such as documentations, lot number, shelf life and special labels, and we make sure each request is carried out. Every DNP customer can be secure in knowing that they will receive exactly what they order each and every time they place an order with us.
