If it's tight it's right. It CANNOT move inside the packing. It must be double boxed with a 2" standoff between the outside of the inner box and the inside of the outside box. The inner box cannot move inside the outer box...NO ifs, ands or buts... I use 1-2" styrofoam plates. NO PEANUTS EVER....
I have NEVER had a PACKING problem only shipping to the wrong address. I've shipped over 45 years. Thing much like stereo gear only EXPENSIVE.. Like 40-75,000.00 dollars and 30-100 lbs.. My stuff couldn't get hurt, there was a 6 week to 6 month waiting period for someone to build a new one... There were no others in the WORLD....
I shipped from the US, Canada, and Mexico, to Germany
I always pack as if it was being returned to me..not to YOU.... Big difference...in the packing... Think GLASS... ok!!!!!
Learn how to PACK, and LABEL the boxes.. NO UPS, sorry they don't even read the labeling. HEAVY, FRAGILE, This End Up!, Handle with care.
Wish you the best in your future, shipping...
