# Special Unit Measures The automated determination of special unit measures is a valuable feature of Dexter that enables businesses to streamline their customs clearance process and ensure compliance with customs regulations. This feature automatically determines whether and which special unit measures are required based on the customs tariff number, and finds or calculates the relevant information from the documents at hand. For example, in the case of alcohol, the feature automatically identifies the special unit measures required, such as the alcohol content, and finds or calculates the relevant information from the documents at hand, such as the alcohol percentage stated on the invoice or other relevant documents.

This ensures compliance with customs regulations and avoids potential fines or penalties. By automating the determination of special unit measures, businesses can save valuable time and resources, and focus on more value-adding tasks. This feature also provides businesses with greater control over their supply chain and enables them to make more informed decisions regarding their import and export operations. Overall, Dexter's automated determination of special unit measures feature is a vital tool that enables businesses to streamline their customs clearance process, ensure compliance with customs regulations, and avoid potential fines or penalties.
