Shipping Information

Ferrous Sulfate products can be shipped over the road and on rail. Because Ferrous Sulfate is listed as a hazardous material with a Reportable Quantity of 1,000 lbs. in the 49 CFR, we must follow the Department of Transportation’s rules and regulations regarding shipping in the United States. There has been some confusion regarding Marking requirements, Bill of Lading descriptions, and CDL endorsement requirements, and we hope the following brief description of these requirements, along with the DOT’s interpretation and confirmation clarifies the legal shipping compliances:

Ferrous Sulfate, when shipped in packages less than 1,000 lbs. is exempt from the Class 9 placarding requirements, therefore, under these packaging conditions, are considered non-haz shipments. When packaged in containers of 1,000 lbs. or greater, a white square on point containing the 3077 ID number ( not considered a placard) is required to be placed on the shipping container or truck (for bulk shipments). A hazardous endorsed CDL is not required for shipments of packages greater than 1,000 lbs. because a placard is not required. Bill of Lading’s shall note as the description in the body – NA 3077, other regulated substances, solid, N.O.S., 9, PG III, RQ (Ferrous Sulfate).
