Raw Material Receiving

In receiving, the material is first quarantined for evaluation. Since there are many quality variables involved, it is reviewed according to the following process:

Step 1: 
Tag: Each bag, barrel or container is tagged with a unique internal lot number for tracking purposes. The supplier lot, item number, manufacturing date and other information are also recorded.

Step 2: 
Paperwork review: The shipping documents, bill of lading, box exterior and Certificate of Analysis are reconciled to ensure they match the original purchase order.

Step 3: 
Sampling: A sample is taken in a designated clean sampling area using sterile or sanitized tools as appropriate. Composite samples are created by sampling from several containers within each manufacturer's lot according to the ANSI/ASQC Z1.9-1993 or a calculated sampling method.

Step 4: 
Sensory testing: Organoleptic (sensory) tests are performed as appropriate, compared to previous receipts of the same material. Does it look, feel, smell, taste right? If not, why? Was the material harvested at a different time of year? Does it have higher or lower moisture content than previous samples? Was it extracted in a different way? The answers must be satisfactory or the material is rejected.

Step 5: 
Physical characteristics testing: Samples may be tested for moisture content, particle size and density, to insure that they are within standard limits, as these characteristics will impact encapsulating and tableting.

Step 6: 
Laboratory testing (see below): The material is quarantined while the samples go to the lab for testing. Our strict internal standards help ensure that our products will meet label claims.

Step 7: 
Pass or Fail: If a raw material is judged unacceptable, it is tagged as `Rejected' and moved to the reject area to be returned to the supplier or destroyed.
