Dear Charles.C,
Im working on HACCP implementation for a catering industry. Can i use the format you gave for the product description? and does the product description goes in the ANNEX section?
I assume by "format" you mean the basic layout structure(s).
Generally IMEX there is no fixed format so the choice is more or less up to you although the form typically needs certain common items as in the examples posted in this thread. The full requirements may vary, eg with the actual product. So the answer to yr query is a qualified YES.
But do note that some organisations seem to have wider expectations. For example, if you download the model haccp manual in the link below, you will see a more intensive style of model product description form. This is atypical IMEX but Mauritius auditors I have no experience.

Re - location, in Codex haccp (as probably per yr OP) this form typically = stages (2 + 3). In my HACCP Plan it goes at the beginning.
PS - You might consider posting yr draft version on the forum if you would like some free evaluation.
