Tariff rate from China to UK

I have been given a code of 29157090 but cannt find it on the listings. Can anyone tell me what if any the import duty is China to UK?
Thanks

Start with just he first 6 digits, 291570. After that it is country specific.
This gives a choice Palmitic and stearic acids and esters. Do you have a description of what this is exactly?
Whichever it works out to be the duty is 5.5% and 20% VAT
