Answers.Body: <p>The nested/hierarchical presentation you're suggesting is perfectly fine for the front end presentation, but you don't want to permanently store your data that way in the back end as it's too rigid and doesn't reflect the fundamental content data model, which in turn makes everything you want to do with the data (such as filtering/searching/sorting) a bit harder.</p>
  
  <p>I'm sure there are lots of different approaches, but for maximum flexibility, if it were me, I would run a few imports consecutively:</p>
  
  <ol>
  <li>Import all the "Makes" into a dedicated section</li>
  <li>Import all the "Countries" into a dedicated category group or section (bear in mind that categories as a concept is rumoured to be going away in Craft 4).</li>
  </ol>
  
  <p>...these first two steps give your editors the flexibility to add/edit/remove Makes and Countries in future - do the same with any other columns you think should be treated that way... the decision would depend on how many items you expect there to be, how often they might require editing, whether they should be searchable/filterable, and to what extent the data should be arbitrary or pre-defined. (For example, the CC rating could be imported into another category group or a simple dropdown field of pre-defined values, whereas the 'Act CC' (Actual CC?) rating would more likely be a plain text field to cater for any arbitrary value).</p>
  
  <ol start="3">
  <li>Import everything else into a dedicated section (maybe called "Products", or "Chains" - Again, "Products" would give you more future flexibility, but you might want to then pre-categorise everything in this import under a new "Chains" category). Use the Model as the title, and create relationships to the Makes and Countries (and whatever other relationships you need). You'd need to decide what fieldtypes to use for the other columns - generally you're best avoiding plain text fields for something like this to maintain future data integrity and make front end searching/filtering consistent.</li>
  </ol>
  
  <p>This is all just fundamental content modelling - It really comes down to how small you want to break things up. Most content modellers err on the side of using highly atomic content and then creating relationships between them, but you can take that concept too far.</p>

Body: <p>I have a sample CSV to test bulk import is feasible before we try it with the real CSV which contains 12000 items.

Comments.Text: Thanks Joshua M but I don't understand what you mean?  As you suggest I have re-imported and created new categories using the 'Make' column.   I then created a Category field attached to my Category Group and added it to the Entry Type. I then created a new Feed (same csv) to import the Models as Entries but the Category Field is not available to map to?

  I would set an [dynamic title](https://docs.craftcms.com/v3/sections-and-entries.html#entry-types) for entry titles ie. `{make.one().title} - {model}`, then have **make** as a category field, **model** as a text field.
  
  It doesn't sound like it matters what the entry title is, but this will make it nicer to manage in the back-end.
