Reclassification information?

As the UK has published a “planned” tariff for the time after UK exit (currently scheduled to become effective on January 1st 2021) - is there some reclassification information available?

As far as I could see, some tariff lines as well as some duties are eliminated. Items classified in those eliminated tariff lines need to be assigned to a new (most likely “other - other”) tariff line.

Is there a file / correlation table to assist with reclassification? WIll this be provided within an API on a regular basis?

Thanks in advance!
