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, can you please provide me with some information about the import you're planning to make? This could include:

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

Additionally, you may want to know about the following:

- Commodity codes: These are used to classify goods for customs purposes and are essential for calculating import duty and VAT.
- Tariff classification: This is the process of determining the correct commodity code for your goods, which will then determine the applicable import duty rate.
- Customs procedures: This includes the steps you need to take to declare your goods and pay any applicable duties and taxes.

Please let me know if you have any specific questions or if there's anything else I can help you with.

Also, please note that I'll be referencing the UK Tariff Guidance
