Loading at Supreme Perlite

Expanded perlite ships by the pallet-load of 4 cubic foot bags, or double-stacked bulk super sacks. All products are quoted FOB from our facility.

Loading Hours

First come - first served. Monday - Thursday, 6 am – 3 pm.




No dock - driver assistance required. We provide the pallet jack, and the driver is expected to move pallets forward into the trailer. Please do not send disabled drivers who are unable to use a pallet jack. Pallets of expanded perlite products weigh between 700 and 900 lbs. total.

Height restrictions and limitations: Double-stacked bulk bags can be 107” tall. Most high-cube trailers can accommodate these, unfortunately, most refrigeration (reefer) units, vans with roll-up doors and some curtain vans cannot accommodate pallets of double-stacked super sacks. When in doubt, measure first and call us BEFORE sending a truck.


Loaded from the side with a forklift, pallets of 4 cubic foot bags and palletized bulk bags will need to be strapped down. Bulk bags of expanded perlite will settle from road vibration and this may cause straps to loosen. Straps will need to be checked and tightened somewhere en route to the end-user (after 50 miles, for example).


Tarping may be required on some flatbed loads. Check with end-user.
