If something deviates materially, it typically means there is a significant or substantial departure from a specified standard, expectation, or requirement. A deviation is considered material if it affects the essence of the agreement or the purpose of the regulation. For example, in a contract, a material deviation might involve a significant change in the quality, quantity, or timing of goods or services delivered, which goes beyond what was agreed upon and impacts the receiving party’s expectations and obligations.
