A revised national standard, (GB/T 18107-2017 effective 1 July 2018), for Chinese redwood has been released by the National Standard Committee replacing GB/T 18107- 2000.
The number of recognised redwood species has been reduced to 29 from 33. The following have now been excluded: Vietnamese padauk (Pterocarpus cambodianus Pierre), maidu (Pterocarpus pedatus Pierre.), black rosewood (Dalbergia fusca Pierre) and ponce’s kamagong (Diospyros poncei Merr.).
According to analysts these changes only reflect rearrangement of species with different names. For example Vietnamese padauk (Pterocarpus cambodianus Pierre) and maidu (Pterocarpus pedatus Pierre.) are regarded as the same as Myanmar padauk (Pterocarpus macarocarpus Kurz), black rosewood (Dalbergia fusca Pierre) is another name for Myanmar blackwood (Dalbergia cultrate Grah.).
In addition to changes in nomenclature, information on 6 redwoods in 8 categories have been modified with new data on wood characteristics.
These changes, say analysts, are aimed at making it more convenient for consumers and for market promotion. The changes also are a reminder to redwood enterprises that the ‘redwoods’ are becoming scarce.
The revision of the national standard for redwoods has disappointed many in the private sector who hoped the revision would add more species in particular mukula (Pterocarpus chrysothrix), from Zambia and bubinga/kevazingo (Guibourtia demeusei).
