Industrial-grade arsenic differs from the dutiable article in that it is produced and refined on a large scale by processes which cannot be regarded as fine-chemical processes, but are in the nature of metallurgical processes, whilst the dutiable article is produced by typically fine-chemical processes for use, for instance, as an analytical reagent. The standard of purity required for the reagent is higher than that of the ordinary industrial grades.
