Hi LMata,
As is been told some records that you are trying to import exceed the max length in company column. I'd like to point you where you can update that max from e.g: 50 to 1000,
Go to Settings

Select arrow down and click on Customizations

Select Customize the system

Expand Entities tab and look for contact, click on that.


Click on fields

Look for company column and click it

locate Maximum Length* field and set a bigger number e.g:50 to 1000

click on save and close

Back in contact, click on publish

Regards.
