■What is Zinc Methionine Sulfate? It is a type of organic zinc designated as a feed additive in Japan. Zinc is a component of metal enzymes, so supplementing zinc helps prevent "skin keratinization disorders, decreased feed intake, weakening of hoof horn, growth disorders, and reduced reproductive gland function." Organic zinc is more efficiently absorbed compared to inorganic zinc because it is organically bound to amino acids. Therefore, when compared to inorganic zinc such as zinc carbonate or zinc sulfate, it shows improvements in productivity and reproductive performance, as well as maintaining immune function. ■Appeal Points Zinc methionine sulfate typically contains 15% zinc, but our company also offers a custom product with 20% zinc. This allows for efficient zinc absorption with a smaller amount added compared to standard products. We believe our pricing is relatively competitive, so please feel free to contact us below.

Magnesium sulfate (Epsom salt) is a fast-acting fertilizer material that is easily soluble in water. It can be used not only in compound fertilizers and blended fertilizers (BB fertilizers) but also as a base fertilizer and top dressing. Magnesium is a key element for plant growth as it is a component of chlorophyll and helps activate enzyme reactions and aids in the absorption of phosphorus. When magnesium is deficient, yellowing of the leaves occurs, leading to a condition known as magnesium deficiency, which results in reduced photosynthetic ability. Magnesium sulfate is water-soluble and fast-acting, making it very effective against magnesium deficiency.

Potassium sulfate is a fast-acting potassium fertilizer that is easily soluble in water. It is suitable for both base and top dressing due to its low leaching. It can be mixed with urea, ammonium sulfate, potassium chloride, superphosphate, and monoammonium phosphate (MAP) and diammonium phosphate (DAP), and is also used as a raw material for compound fertilizers and BB blended fertilizers.

Oxychloride zirconium is generally used as a raw material for zirconium compounds and is utilized in various applications as ceramics. Ninety percent of the oxychloride zirconium in Japan is imported. Our company has been importing and selling oxychloride zirconium from manufacturers with the largest production capacity in China for over 20 years, establishing a solid logistics and supply system. Its characteristic is low impurities. In particular, it can accommodate low iron content (see the specifications example below), which has the advantage of suppressing discoloration of products and distortion of electrical properties. Therefore, it is adopted by domestic manufacturers that produce and develop zirconium compounds, which are often required to be of high quality by end users, such as fine ceramics for the electronics field and dental materials where color is important.

■What is Zircon Sand■ Zircon is a type of mineral, and the origin of the word "zircon" comes from the Persian word "zargun" (meaning gold-colored) and the Arabic word "zarquin" (meaning brown), due to the prevalence of golden-brown stones. Minerals containing zircon are often found in sand deposits formed from the weathering of rocks and their subsequent erosion by water. The minerals containing zircon primarily occur as zircon silicate combined with silica, and some can be found as transparent red crystals, which are referred to as hyacinth in the jewelry industry. The refined and extracted forms of these minerals are generally called "zircon sand." ■Key Points of the Proposal■ The global production of zircon amounts to 1,500 thousand tons, with Australia, South Africa, and China accounting for about 80% of the total. Japan is a net importer of zircon, relying on imports for 80% of its ore from South Africa and Australia. ([Source: JOGMEC "Mineral Resource Material Flow 2019"]) ⇒ Our company has secured suppliers of zircon sand from Indonesia, in addition to the above, and can provide proposals tailored to specific applications.

■What is Boric Acid■ Boric acid is a chemical substance represented by the chemical formula H3BO3. It is generally produced by reacting a mineral known as borax with sulfuric acid, followed by filtration, cooling, and re-dissolution for purification. It is widely used in glass, enamel glazes, abrasives, ceramics, and as a raw material for boric acid bait. ■Key Points of Proposal■ In Japan, boric acid raw materials are not produced domestically. Therefore, the ores and intermediate products that serve as raw materials for boric acid are largely dependent on imports from overseas. The main sources of boric acid abroad are the United States and Russia. Recently, due to the situation between Russia and Ukraine, the supply of boric acid raw materials and boric acid itself has been in an uncertain state. ⇒ By purchasing boric acid from a third country, Peru, we can contribute to the establishment of a stable raw material supply system for your company.
