Since the moment that your supplier, repacks the food color after buying it, they couldn't be included on the scope of BRC Agents and Brokers and that product would be included on the scope of BRC FS v 7.
Yr comment seems a logical interpretation to me assuming "repack" means any activity which alters the "presentation" of the received/stored/shipped material (Module 8 [see below] does reference Primary packaging [Hmmm]) .
@Whitney - As per yr Post 9, and above quote, the supplier you mention is probably from your POV not a broker for the relevant item "abc" . So, assuming that "abc" was included in the scope of B's BRC7 certificate, the latter would presumably suffice.
Note that, If B did no repacking, B presumably would be regarded as a broker for "abc". Four options would then seem (to me) to be available to B -
(i) B could choose to include "abc" within scope of B's BRC7 certificate via Module 8 (see posts 15-16)
(ii) B could decline option (i) which would result in "abc" being specifically excluded from B's BRC7 scope (see text Pg2, module 8),
(iii) B could get further certification to Broker Standard for item "abc",
(iv) B could take no further action regarding "abc"
The crux of A's BRC7 certification and involvement with steps (i - iv) would then be as required to fulfill the details noted in this post -
However, the "sensitivity" of some aspects of the above has resulted in a (temporary?) deferral of the full requirements, see the attachment of post 21.
