Using this value
Either form of this value goes in the google_product_category attribute: the numeric ID (1622) or the full path ("Cameras & Optics > Photography > Darkroom > Photographic Chemicals"). Both are predefined values for the same category. The ID is the sturdier of the two, because renaming any segment above this one changes the path text and leaves the number alone.
Bear in mind that google_product_category is an optional attribute. Google assigns a category automatically, and your value is treated as a signal rather than an override. When an override actually applies.

This path has no comma, so an unquoted cell holds it as it stands — which is not true of every category in the taxonomy. The numeric ID, 1622, is the form that does not depend on how the file is quoted.

Questions about Photographic Chemicals
What is the Google product category ID for Photographic Chemicals?
1622. The full path, "Cameras & Optics > Photography > Darkroom > Photographic Chemicals", is the same category written the other way. The ID is shorter, and renaming a segment above this one changes the path text while leaving the number alone.
Is anything more specific than Photographic Chemicals available?
No. Photographic Chemicals is a leaf of Google's taxonomy at level 4, so 1622 is the most precise value this branch offers. If it does not describe your product closely enough, the answer is a different branch, not a deeper one.
Where does Photographic Chemicals sit in the taxonomy?
At level 4, under Darkroom (41). The chain from the top is Cameras & Optics → Photography → Darkroom → Photographic Chemicals. If your product does not belong under Darkroom, it does not belong here either — check the level above before going deeper.
What should I use if Photographic Chemicals is not quite right?
Look across the rest of Darkroom first — there are 4 other categories at this level: Developing & Processing Equipment (2234), Enlarging Equipment (2520), Photographic Paper (2804), Safelights (2600). If none of them fits either, the problem is higher up: go back to Darkroom (41) and pick a different branch from there rather than settling for the closest thing on this one.
How big is Photographic Chemicals compared with the categories next to it?
It is third largest of the 5 at its level, carrying 0 categories below it. A bigger category is not a better one — it just means more of the taxonomy is still open below you after you pick it.
What is the difference between Photographic Chemicals and Photographic Paper?
They sit side by side under Darkroom and start with the same word, which is why they get swapped. Photographic Chemicals is 1622; Photographic Paper is 2804. The paths are the reliable way to tell them apart — compare "Cameras & Optics > Photography > Darkroom > Photographic Chemicals" with "Cameras & Optics > Photography > Darkroom > Photographic Paper" before you submit.
