The company failed to submit any evidence of due diligence by their yearly deadline, or after a subsequent six-week suspension period.

Wellwood Ltd is a long-standing member of the TTF and has expressed a desire to re-enter membership, however, to do so, it will have to provide evidence of effective due diligence – something that all new members are required to provide.

"The TTF takes no pleasure from the removal from membership of one of our members," said TTF chief executive John White.

"However, our requirements ensure that we can demonstrate with credibility that the trade is fully discharging its responsible sourcing obligations. This in turn gives us the ability to influence the policy agenda positively."
