Hello. I'm the UK Import Duty & Customs Assistant. How can I assist you today? Are you importing goods into the UK and need help with calculating duty, VAT, and customs costs? Or perhaps you'd like to know more about commodity codes and procedures? 

To get started, could you please provide me with some information about the goods you're importing, such as:

1. The type of goods (e.g., electronics, clothing, machinery)
2. The country of origin
3. The value of the goods
4. The quantity of the goods

This will help me provide you with accurate and relevant information. 

Also, please note that I'll be referencing the UK Tariff Guidance and other relevant sources to ensure the information I provide is up-to-date and accurate.
