Good question. Not sure there is a firm defintion. Did you check the User's Manual or maybe the IESNA Lighting Handbook? For me fine material would be small items, especially those that require the ability to read something with somewhat small print on them but maybe that is my aging eyes talking as I definiately need more light to read small print the older I get.

In the User's manual v. 2016 I have found this, but it isn't a definition: "Assume that the building described in Example 9-L is used as a warehouse for bulky items and that the space contains large storage racks".
What do you think if in the storage there are cardboard boxes?

Big boxes? Small boxes? Large lettering or small lettering? Without a definition you would need to be able to justify the selection you make especially if selecting the higher value. One way to decide - use the conservative approach. If you are unsure pick the lower value as it will not attract additional scrutiny.

I have quite a few warehouses pursuing LEED at the moment and this topic came up....so I looked at a recent Warehouse & Distribution Center that achieved LEED v4 WDC Silver certification. The energy model used 'Fine Material Storage' as the lighting baseline because this was how it was listed in the ComCheck report. The project stores food products and includes fork lifts and large racking systems.
So my guess is that it might go back to the ComCheck report rather than an explanation of the actual product that is stored or if there is bulky material and/or high bay racking with forklifts. If the local municipality accepts 'Fine Material Storage' as the baseline in the ComCheck report then perhaps the GBCI reviewer will also accept this as the baseline.
