On Tuesday, August 31, U.S. Customs and Border Protection Officers at the Port of Sweetgrass, MT refused entry on a shipment of Chinese porcelain vases coming from Canada which contained an unknown plant material present throughout the entire shipment. CPB Officers used Vehicle and Cargo Inspection gamma ray technology to inspect the container, which showed an unmanifested substance inside all 83 vases. Further inspection of the material revealed three to four inches of a wheat-like substance including stems, heads, chaff and dirt inside each of the vases. CBP Officers also noted that the palletized boxes, containing the vases, were shrink-wrapped on wood slats where pieces of pallet stock were nailed together holding the boxes together within the shrink-wrap.
