China Customs bars endangered animal and plant products from leaving
The China Customs passenger guide lists among 'Articles Prohibited from Exportation', verbatim: 'Endangered and precious rare animals and plants (including their specimens), their seeds and reproducing materials.' It sits on the same prohibited-export list as 'Valuable cultural relics and other relics prohibited from Exportation' — so a wildlife-derived souvenir is measured against a first-party China Customs prohibition on the way out.
