Shipping Vinyl LP's

I shipped 200 Lps across the country twice in the same boxes via USPS media mail and they did arrive just fine.
I used thick imported wine boxes. Hard to come by I admit.
But as long as the boxes can be dropped 3 feet and survive completely intact, you are covered. If the box is so heavy/flimsy that it cannot pass such a test, you are asking for trouble.
The Amtrack advice may be the solution... never used them, but sounds worth a shot.

I mailed a bunch of LPs USPS to Hong Kong. I went to U-Hual and got the box that is just right for albums and the next size bigger (12x12x12 and 14x14x14 I think).

Put the albums in the small box and it in the larger with wadded up newspaper between to absorb some shock. Tape well. It worked great and all 500 arrived safely in about 12 boxes.

Hey Mitch,
Try going to your local pack and ship and getting 13x13x4
or 13x13x6 boxes. You want to use multiple boxes as they
will be smaller and lighter and less likely to be damaged.

Plus you want to pack your albums "tight" to help prevent any possable warping if they spend time in a hot truck,
warehouse,etc... Put your padding around the albums, not
between them.

USPS Priority insured would get them to you fast, if you
are going all that way to do this yourself why go slow mail
to get them home.

Too bad I dont live closer to you, you could borrow my VPI
to clean your new vinyl.

Use Fedex Ground and insure them for $2000 [so they won't screw around]. It will still be your cheapest and safest option. However, make sure you pack well.

I've used the U-Haul boxes sized 13x13x16 with great success. The trick is to cut up a second box such that it fits inside the first box and you end up with a double bottom that extends up the two 16" sides a few inches. It keeps the bottom from blowing out.

About 110 albums per box. Weighs in around 65 pounds. I've had good luck with USPS. Cost is about $25 with their Media Rate, but some of their counter help isn't aware of the rate or isn't aware that it applies to albums, but it specifically does.
