I believe the answer is:

instate

I'm a little stuck... Click here to teach me more about this clue!

'tea-tins produced with due ceremony' is the definition.
I can't judge whether this definition defines the answer.

'tea-tins produced' is the wordplay.
'produced' is an anagram indicator.
'tea'+'tins'='teatins'
'teatins' anagrammed gives 'INSTATE'.

Can you help me to learn more?

(Other definitions for instate that I've seen before include "Establish, install" , "Tea tins (anag.)" , "Put in possession" , "Set up" .)

I've seen this clue in The Irish Independent.
