Split a column into multiple

In the future, try to provide a reproducible example FAQ: How to do a minimal reproducible example ( reprex ) for beginners. I've tried to make one based on the screenshot but you should do this when posting a question. Here's an example which I think does what you want assuming you've imported the data into R already:

library(tidyverse)

Products <- tibble(
   G=c("HS codes: 0105 0106 0207 0407",
              "HS codes: 0105",
              "HS codes: 0105 0207 0407",
              "ICS codes: 67.120.20"
              )
)

Products_split <- Products %>%
   mutate(
      Code_01=str_extract_all(G, "01[0-9]{2}"),
      Code_02=str_extract_all(G, "02[0-9]{2}")
      )

Products_split
#> # A tibble: 4 x 3
#>   G                             Code_01   Code_02  
#>   <chr>                         <list>    <list>   
#> 1 HS codes: 0105 0106 0207 0407 <chr [2]> <chr [1]>
#> 2 HS codes: 0105                <chr [1]> <chr [0]>
#> 3 HS codes: 0105 0207 0407      <chr [1]> <chr [1]>
#> 4 ICS codes: 67.120.20          <chr [0]> <chr [0]>

Products_split %>% 
   pull(Code_01)
#> [[1]]
#> [1] "0105" "0106"
#> 
#> [[2]]
#> [1] "0105"
#> 
#> [[3]]
#> [1] "0105"
#> 
#> [[4]]
#> character(0)
Products_split %>% 
   pull(Code_02)
#> [[1]]
#> [1] "0207"
#> 
#> [[2]]
#> character(0)
#> 
#> [[3]]
#> [1] "0207"
#> 
#> [[4]]
#> character(0)
