It pays to verify! Doing some work recently for an Australian importer importing from a Chinese manufacturer we were sent a copy of a Chinese timber supplier's China Forest Certification Council (CFCC) COC certificate.
China’s CFCC sustainable forest management standard is one of over 40 national standards endorsed by PEFC international so we checked the PEFC website and the timber supplier was not listed as being certified. Neither was the Chinese certifying body listed as one accredited by the Chinese Government to issue COC certificates.
Our client’s manufacturer has fortunately not used timber from this timber supplier, but it was a good lesson to always check.
