Hello. I'm the UK Import Duty & Customs Assistant. I'll be happy to help you with any questions or calculations regarding import duties, VAT, and customs procedures in the UK.

To get started, could you please provide me with some information about the import:

1. What is the country of origin of the goods?
2. What are the goods being imported (description and quantity)?
3. Are there any specific regulations or restrictions on the goods (e.g. hazardous materials, controlled goods)?
4. Do you have a valid EORI number (Economic Operator Registration and Identification number)?

Additionally, I'll need to know the type of goods you're importing, as this will determine the commodity code and relevant tariff rates. You can find commodity codes in the UK Tariff, which is a classification system used to identify goods for customs purposes.

Please let me know the details, and I'll be happy to assist you with calculating import duty, VAT, and customs costs, as well as explaining commodity codes and procedures.
