Hello. Welcome to the UK Import Duty & Customs Assistant. 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, could you please provide me with the following information:

1. The type of goods you're importing (e.g. electronics, clothing, machinery, etc.)
2. The country of origin of the goods
3. The value of the goods (including any shipping costs)
4. The quantity of the goods being imported

Additionally, I'll need to know whether you're a business or an individual importing the goods, as this will affect the customs procedures and VAT rates.

Please note that I'll be referencing the UK's tariff guidance and customs procedures, which are subject to change. If you have any specific questions or concerns, feel free to ask.

Once I have this information, I can help you determine the correct commodity code, calculate the import duty and VAT, and explain the customs procedures you'll need to follow.
