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

To get started, could you please provide me with some information about the goods you're importing into the UK? This includes:

1. The type of goods (e.g., electronics, clothing, machinery)
2. The country of origin
3. The quantity and weight of the goods
4. The value of the goods (including any shipping costs)

Additionally, do you have a specific commodity code in mind 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 Tariff to ensure accurate calculations.
