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 will help me understand the calculations and procedures involved. Please provide the following information:

1. Description of the goods
2. Country of origin
3. Quantity of the goods
4. Value of the goods (including any shipping or handling costs)
5. Any relevant Harmonized System (HS) commodity code or classification

Additionally, I'll need to know whether you're using the 'De Minimis' rule or if you're importing goods valued above the £135 threshold. 

Also, please let me know if you have any specific questions or areas of concern, such as:

- Calculating import duty and VAT
- Understanding commodity codes and classification
- Procedures for customs clearance
- Any specific regulations or restrictions

I'll do my best to provide you with accurate and up-to-date information based on the UK Tariff Guidance and other relevant regulations.
