International standards define the a common set of processing and supply criteria for products and in the Titanium Industry several exist and are categorized into mill product types. 

There are several types of standards that cover the production of titanium, including:

• ASTM International standards: These standards are developed by ASTM International, a global organization that develops and publishes technical standards for a wide range of materials, including titanium. ASTM standards cover various aspects of titanium production, including chemical composition, mechanical properties, and testing methods.

• ISO standards: The International Organization for Standardization (ISO) develops and publishes international standards for various industries, including the aerospace, medical, and construction industries, which all use titanium. ISO standards for titanium cover topics such as chemical composition, mechanical properties, and testing methods.

• AMS standards: The Aerospace Material Specifications (AMS) standards are developed by the aerospace industry and cover various aspects of titanium production, including chemical composition, mechanical properties, and testing methods.

• MIL-STD standards: The Military Standard (MIL-STD) standards are developed by the US Department of Defense and cover various aspects of titanium production, including chemical composition, mechanical properties, and testing methods.

• Ti Grades standards: Alloys of titanium are designated by their unique Ti grade number, per ASTM international and AMS standards, and are defined by their chemical composition and mechanical properties.
