Do we need to be BRC Iop Certified for reworking labels?

We are a label printer and print some direct/indirect food packaging items.  I am doing a GAP audit for one of our plants and I am wondering if I need to proceed.  This building does not ever print any labels.  They print perforated tickets and liner less easy release printer tape for the mailing industry.  The reason they wish to be certified is that due to the lack of space in our plant, all of our returned product gets shipped to this plant regardless of the type of label/packaging.  If they are able to perform some rework on labels that would be considered food labels, do they NEED to be certified?  When I say rework, what I am referring to is they would put the rolls of labels on a turn table that would put the labels onto another core in order to flip the label around so the applicator is not applying then upside down (a.k.a. wrong unwind), or they would put the rolls on the same table and move it through slowly and look for possible defects.

Any help would be awesome!!!

detail is a little confusing....You are a label printer for direct/indirect food packaging........but do not ever print labels ?

Do you mean you have multiple Buildings on 1 site and the building you are describing does not print the labels...leaving other buildings on site that do ?

We have multiple sites.  Building 1 is BRC certified, building 2 is not.  All returned product is shipped to building 2.  We would like to allow #2 to perform reworks but some of them are direct food or pharmaceutical.   Building 2 does not print the same items or categories of packaging that #1 does.

Does this help clarify?

Hi

yes thanks. What re work is going to be considered. Re Pallet, Re package, Opening product to re pot, or replace labels ( If replace labels how will this happen) have you conducted a risk assessment on rework in this area
