Why are some anchor bolts required to be galvanized, while others do not have this requirement?

I saw it online – why are some anchor bolts required to be galvanized, while others don’t have this requirement?
Aren’t they all enclosed in concrete?
If the area has a humid climate or water tends to accumulate on the ground, using galvanized iron components can effectively prevent corrosion. If it is in a dry environment, there is no need to deliberately apply preservatives.
I’ve seen requests for half to be galvanized, with the part enclosed in concrete requiring hot-dip galvanizing

In addition, in some areas where grounding is enhanced, salts are often buried around the grounding electrodes to improve conductivity; the anchor bolts used in such places also need to be treated to prevent corrosion. These days, hot-dip galvanizing is likely to be the preferred method for galvanizing; it’s a simple and reliable process, though the cost is slightly higher. Many other workpieces are galvanized after completion; hot-dip galvanizing does not impose any requirements on the shape of the workpieces.
Salt-alkali soil in coastal areas might require such things; moreover, in some areas, the site investigation reports may specify special requirements for the rebar in concrete based on the soil characteristics
It seems to be related to geological conditions. The anchor bolts provided with the foreign equipment for our project have all been galvanized. There are none domestically. It has been suggested that galvanizing results in insufficient adhesion. I still haven’t figured out which one is correct
The same doubt; waiting for an expert to provide an answer
