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 details about the import you're making? This will include:

1. The type of goods being imported
2. The country of origin
3. The value of the goods (including any applicable duties and taxes)
4. The quantity of the goods
5. The mode of transport (e.g. air, sea, road)

With this information, I can assist you in determining the correct commodity code, calculating the import duty and VAT, and explaining the customs procedures you'll need to follow.

Additionally, I'll be referencing the UK Tariff Guidance, which is available on the UK Government's website.

Please provide the necessary details, and I'll do my best to help.
