As the largest export volume of magnesium oxide manufacturer in China, Meishen Technology found a serious of problems in exporting the magnesium oxide. Especially in the aspect of magnesium oxide quota, it is one of the big obstructs to effect the export of Chinese magnesium oxide.
At present, when identifying the “chemical pure magnesium oxide” which don’t need export quota, the commodity inspection and customhouse always simply demand the content of magnesium oxide should over 98%. However, as a kind of fine chemical, the chemical synthesis magnesium oxide quality has various of requirements from foreign users. Most of requirements from them is the content should between 90% and 95%. At the same time, it should contain a certain amount of magnesium hydrate and magnesium carbonate.
Among these, the content of detrimental impurities are required as low as possible, the total content can not over 25, such as iron, calcium, chlorine, insoluble matter in hydrochloric acid and so on. The west brine method manufacturing technique can meet these needs perfectly. In other words, if the requirement for magnesium oxide content is more than 98%, it can not meet the requirements for other contents. It is not accord with chemical synthesis’s production and market actual application condition.
Therefore, in order to promote Chinese magnesium oxide into international market and create high quality magnesium oxide brand, the Hebei Meishen Technology Co., Ltd puts forward a better and more precise export quota of magnesium oxide.
