The US Commerce Secretary has announced that the US will temporarily lift tariffs imposed on Ukraine during the Trump administration to help Ukraine recover its economy and continue to show support for the Russia-Ukraine situation. "For steel mills to remain an economic lifeline for the Ukrainian people, they must be able to export steel," the Commerce Department said in a statement.
The Biden administration will announce the lifting of steel tariffs on Ukraine for one year. Ukraine is a fairly small supplier of U.S. steel, shipping about 218,000 tons in 2019, ranking it 12th among foreign suppliers to the United States, the report said. The U.S. Commerce Department noted that the steel industry is uniquely important to Ukraine's economic strength, with one in 13 people employed in the steel industry.
Affected by the ever-changing international situation, the supply and prices of international bulk zinc sulphide are still very uncertain.
What is zinc sulfide?
Zinc sulfide is an inorganic compound with the chemical formula ZnS, which is a white or slightly yellow powder, which becomes darker when exposed to light. It is stable in dry air, and gradually oxidizes to zinc sulfate when placed in humid air for a long time or when it contains moisture. White or slightly yellow powder. It turns into crystals when burned in H2S gas. The α variant is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700°C; Exist in sphalerite. Insoluble in water, soluble in acid. See the sun color darken.
Zinc sulfide (ZnS) is a naturally occurring salt and a major source of zinc. It exists in two common crystalline forms (polymorphs): sphalerite ("sphalerite"), which has a cubic crystal structure and is the predominant form in nature.
It will be converted into zinc sulfate when placed in humid air for a long time. It is generally derived from the action of hydrogen sulfide and zinc salt solution. If a small amount of Cu, Mn and Ag are added to the crystal ZnS as activators, they can emit different colors of fluorescence after being illuminated. For analytical reagents, coatings, paints, white and opaque glass, filling rubber, plastics, and for the preparation of phosphors.
What is zinc sulphide used for?
The most common use of zinc sulfide is as a pigment in paints, plastics and rubber. It can also be used as an analytical reagent, a matrix of phosphors, a photoconductor material; it can also be used in the manufacture of dyes, coatings, pigments, glass, and curing oil.

At present, international supply chains were shocked, and logistics and transportation efficiency decreases. Geopolitical conflicts further aggravate uncertainties about the European and American economic recovery and the global commodity supply. For this reason, I assume the price of the zinc sulphide would not decrease significantly in the short term.
