Timber trade (4)

I believe the answer is:

deal

This clue is a double definition.

'timber' is the first definition.
(deal is a kind of timber)

'trade' is the second definition.
('deal' can be a synonym of 'trade')

(Other definitions for deal that I've seen before include "Kent town" , "Board" , "Share out (cards); wood" , "Distribute playing cards" , "Agreement; hand out cards" .)

I've seen this clue in The Guardian, the Evening Standard and The Globe and Mail.
