Vinyl Records - Shipping, max/min temperatures

I don't think you have anything to worry about.  If you're paranoid about condensation forming when you open the boxes at the destination, just line the shipping boxes with plastic bags, fill with LPs, and then tie the bag to seal the records.  When at the new destination, let the records acclimate to the new temp before opening the bags.  Condensation has no chance of forming.

But again, I wouldn't worry about it.  Unless the records are very cold and you open the boxes in a rain forest, no meaningful amount of condensation will form.  I assume you'll be opening the boxes in a climate controlled environment with reasonable relative humidity.  I open boxes of stuff that was shipped to me all the time in the winter (including records) and condensation never forms on anything.

Thermostatic Controlled Reptile Heat Mats are quite cheap in the US, these are commonly 12V and will comfortably keep a space heated to a Temp Range of 10 Celcius to 25 Celcius.

It would not be too difficult to arrange for these to be used in a vehicle.

What?  Do we have AI posting in the forums?

btanchors - How large is your record collection that you will be shipping?

Cold temps probably won't be a problem. I'd say the risk is that the get dropped etc when cold which could damage them when they are brittle.  However, if they are packed tightly into boxes or crates so that they cannot move, the risk is minimal.  

If they aren't packed correctly, the risk is there independent of temp.

The record collection is not that large - perhaps 700-800 albums  They will be packed in 13 inch double-layered corrugated cardboard boxes.  Naturally, they will be stored near vertically in the boxes, but not packed too tight.
