Room # 8102 DHM-10 Washington, D.C. 20590 Dear Mrs. LaValle: Per our telephone conversation. I am writing this letter to clarify our request for a ruling on CRF 177.834G, and how it relates to the packaging and shipment of our product, Hexamethylenetetromine. This product is shipped in either 2,000 LB FIBCs or in 50 LB bags (7 bags per layer, 6 layers high with glue between each layer). These bags are placed on a slightly undersized and unsecured pallets. These units, when loaded, are placed with the bags pressed against the adjacent units bags. Therefore, the bag or bags are blocking thernselves against each other and the trailer walls. This along with load locks on the last two units should prevent motion when in transit. With the use of performance oriented packaging and our blocking method, we feel that each truck load of material wall arrive at it's destination safely as has been our history for many years now.
