Your source for Zinc Oxide

Since 1974, G.H. Chemicals has established itself as a world class manufacturer of high quality French Process zinc oxide at its modern production facility in Saint Hyacinthe, Quebec, Canada.

Our team of trained and dynamic employees enables G.H. Chemicals to fulfill its corporate mission: Consistent Quality, Consistent Service, Consistent Value and Security of Supply.

G.H. Chemicals manufactures multiple grades of zinc oxide in order to supply such industries as tire, custom compound rubber and plastics, ceramics, agriculture, lube oil additives and specialty chemicals.

G.H. Chemicals is the manufacturer of IRM 91 (ASTM) zinc oxide reference material for the world’s rubber compounding industry. It can be ordered directly from G.H. by visiting our Contact Us section.

Our unique production method allows G.H. Chemicals to manufacture one of the purest zinc oxides available to both the pharmaceutical and food industry (USP and FCC). G.H. Chemicals was recently granted the world’s first government GMP License (Good Manufacturing Practice) to produce USP zinc oxide serving as an Active Pharmaceutical Ingredient (API). The license is also the equivalent to the ICH Q7 Certification and therefore allows the importation of G.H. Chemicals zinc oxide into Europe. Please visit the GMP section of our website for more information.

World class accreditations such as C-TPAT (United States), REACH (Europe), GMP, and our packaging in UN registered bags for shipment from the nearby port of Montreal, all ensure that G.H. Chemicals zinc oxide can be exported anywhere on the planet.
