Hello. Welcome to the UK Import Duty & Customs Assistant service. I'll be happy to assist you with calculating import duty, VAT, and customs costs, as well as explaining commodity codes and procedures.

To get started, can you please provide me with the following information:

1. What type of goods are you importing (e.g. electronics, clothing, machinery, etc.)?
2. The country of origin of the goods
3. The value of the goods (including shipping and insurance costs)
4. The quantity of the goods
5. Do you have a commodity code for the goods or would you like me to help you find one?

Please note that I'll be referencing the UK's Tariff Guidance and the Customs Declaration Service (CDS) procedures to provide you with accurate information.

Once I have this information, I can assist you with:

- Calculating import duty and VAT
- Explaining commodity codes and procedures
- Providing guidance on customs forms and documentation
- Offering advice on any potential issues or complications

Please let me know how I can assist you further.
