Hello,
Can you please mention the version?

Are you talking about Products-> Pricelists, right? Or items in the Price tab in Product?

Sure it’s 

19.2+e.

Yes Sales->Products->Pricelists.

So company 1 I imported a file which gives me

I cant remember how I loaded them but there is no import for products within pricelist: 

@Chris thanks but that's to import pricelists, not pricelist items.

@Santosh I go to the pricelist but there is no 'Pricelist Items' button anywhere. I only have two views; Sales->Products->Pricelists which shows a table of all pricelists. If I go into a pricelist I can add a rule but no option to import anywhere.

I have a call today with one of the pre-sales guys at Odoo so will ask and report back.

You can't import pricelist items directly. you can achieve this by adding like this columns into excel file
item_ids/id item_ids/applied_on
__export__.product_pricelist_item_14_bd9b3d31 Product
website_sale.item_benelux All Products

Hi Gary - I added an example of an Excel file that should allow you to add products to a price list.

First off, thank you all for prompt and helpful replies, it is appreciated and hopefully as my learning improves I can pay it forward!

OK, so I figured it out. As some of you have suggested you import at the price list level rather than an 'items' level.

So I created a pricelist; Mitel List GBP and then exported it to get the ExternalID. Then my CSV is simply:

product_id/id,fixed_price,pricelist_id
10000,530.0,__export__.product_pricelist_203_53c91775
....

Then on the import I have:
product_id/id mapped to Pricelist Rules / Product /External ID
fixed_price mapped to Pricelist Rules / Fixed Price
pricelist_id mapped to External ID

And that works!

thanks again all!

Gary
