Decision No. 75/2003/QD-BNN of the Ministry of Agriculture and Rural Development issues the industry standard for industrial salt (NaCl), specifying technical requirements, classification, testing methods, packaging, labeling, transportation, and storage. The Decision takes effect fifteen days after its publication in the Official Gazette.
要点
- The industry standard for industrial salt (NaCl) applies to products used as raw materials for industrial production and is classified into three grades: Superior grade, Grade 1, and Grade 2.
- The NaCl content must not be less than 98% by weight of dry matter in the Superior grade, 96.50% in Grade 1, and 95% in Grade 2.
- The moisture content must not exceed 5%, 6%, and 8% respectively for the Superior grade, Grade 1, and Grade 2.
- The insoluble matter content in water must not exceed 0.25%, 0.30%, and 0.50% respectively for the Superior grade, Grade 1, and Grade 2.
- Testing methods follow TCVN 3973 - 84; packaging may be loose or in bags, with labeling as prescribed.
