Regulatory compliance is perhaps the most daunting challenge in importing APIs. Different countries have distinct regulations governing the quality, safety, and efficacy of pharmaceuticals. In the United States, for example, the Food and Drug Administration (FDA) imposes stringent requirements on the importation of APIs, mandating that they meet the Good Manufacturing Practices (GMP) standards. Non-compliance can lead to significant consequences, including import bans, product recalls, and legal sanctions. Therefore, pharmaceutical companies must maintain comprehensive knowledge of both local and international regulations to ensure that their imports comply with all relevant guidelines.

At low concentrations, the viscosity of HEC solutions is relatively low as the polymer chains are not interacting with each other. However, as the concentration of HEC increases, the polymer chains start to entangle and interact, leading to an increase in viscosity. This increase in viscosity continues until a critical concentration is reached, beyond which the viscosity levels off or even decreases due to the formation of a gel network
