Prepared binders for foundry moulds or cores; chemical products and preparations of the chemical or allied industries (including those consisting of mixtures of natural products), not elsewhere specified or included
In plain English
This category covers prepared binders for foundry molds or cores, along with various chemical products and preparations from the chemical or allied industries that are not listed elsewhere. Specific items include metal carbides, non-refractory mortars and concretes, and sorbitol that does not fall under other specific classifications. The remaining subcategories group chemical mixtures based on the presence of particular substances, such as oxirane, polychlorinated biphenyls, various pesticides, and specific flame retardants or plasticizers. A final group addresses preparations consisting mainly of specific methylphosphonate compounds or polyglycol esters of methylphosphonic acid.
