China Clay
From Cargo Handbook - the world's largest cargo transport guidelines website
Description
A white or greysih powder shipped in bulk and sometimes in paper sacks.
Used as a filler and coating for paper, and in the manufacture of refractories, ceramics, cements and fertilizers. When china clay is intended for use in the manufacture of paper or ceramic ware, such as bone china pottery, damage by salt water and other contaminants renders the clay useless. The carrying vessel needs to be cleaned, as particles of rust, coal, etc., entail considerable work and expense in cleaning the clay.
See IMDG Books. Listed under Clay in the Code of Safe Practice for Solid Bulk Cargoes in the supplement to the IMDG Books under Clay.
