Wholesale Shipping & Packaging Information:
- Default Packaging: Default packaging is in fiber drums. Weight of drum depends on the grit size.
- Minimum Order Quantity: 10 lb per grit size
- Tote Packaging: We can also package this in 2,200 lb super sacks. (1 metric ton)
- Discount Pricing: Please use our Quote Request form to obtain custom pricing on larger quantities, with freight. Remember to tell us your ship-to address and the total number of lbs or tons you want a bid on.
-
Loading Dock: Generally, you need to have a commercial address with loading dock to receive orders over 200lbs. If you do not, we can ship it to a local terminal and you pick it up yourself from the terminal. We can also ship to a residential address, but this is very costly and not recommended.
