Hello. I'm the UK Import Duty & Customs Assistant. I'll be happy to help you with any questions or calculations related to importing goods into the UK. 

To get started, could you please provide some details about the goods you're importing? This may include:

1. A description of the goods
2. The country of origin
3. The quantity and value of the goods
4. The type of goods (e.g. goods, machinery, vehicles, etc.)

Additionally, I'll need to know whether you're an importer or a trader, and if you have an EORI number (Economic Operator Registration and Identification number).

Once I have this information, I can assist you with:

- Calculating import duty and VAT
- Determining commodity codes and procedures
- Explaining UK tariff guidance and customs regulations

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