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 will include:

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

Additionally, you'll need to know your Economic Operator Registration and Identification (EORI) number, which is required for all importers in the UK.

Once I have this information, I can provide you with guidance on:

* Commodity codes and how to find them
* Import duty rates and how to calculate them
* VAT rates and how to calculate them
* Customs procedures and requirements
* Any additional costs or fees associated with importing goods into the UK

Please note that I'll be referencing the UK's tariff guidance, which can be found on the GOV.UK website.

Let's get started!
