How does it look down the hole?
Likely surface rust. Screwing it on shouldn’t let that thread rust get into the oil flow.
I’ve seen this before on cartridge filters with a built in bypass. I haven’t used them. This one is be more inclined to if I could see well inside and wipe the threads down before refilling.

I ordered four of these. All of them look like they have rust issues. Inside of them look clean. I'm planning to open up one of them and examine the internals.
If it is going on a beater car, wipe the threads off with a rag that has a couple of drops of clean oil on it. That will probably do a decent job of cleaning them. If it is a nice car, it is a gamble.
Has anyone ever performed an autopsy on a slightly rusted filter like that?
They should have sealed the end like a Premium Guard. Did they come that way? I would worry that the moisture would compromise the media, personally.
I wouldn't but I'm a bit obsessive. If you wipe the threads w/ an oily rag make sure to effectively turn the filter away from you.
Curios as to where you bought these from? Could truly be NOS

I think Hengst makes one of the best solid construction filters, but they are not meant to be stored long term and/or in humid environments. Even the cheap Asian made filters will most time be oil fogged on the can inside during manufacture to give some shelf stability against corrosion.
FWIW, I would have used that filter.

Yes I have used Hengst a number of times in the past with no issues. This shipment was recievd on Monday. Probably the storage facility that it came from was no good!
Rockauto by chance? They can have some old stale stock or buyouts sometimes.
I missed that post before stating that.

Kinda explains why Japanese, Korean, Tawainese, and other SE asian filters have the plastic over the ends...its so darn humid in those countries.
IMO the trip over the ocean in a shipping container on a freighter is pretty humid too!
