Figure 2. The supply chain of the Thai ivory trade involves five supply chain actors: tusks harvested by elephant owners are passed to manufacturers either via direct trade between elephant owners and ivory manufacturers or via intermediaries, who are particularly important for manufacturers without access of local ivory e.g., manufacturers in Nakhon Sawan and Uthai Thani of the North. Finished ivory products are passed along the chain to final consumers through networks of manufacturers and retailers. While the flow of ivory from sources to consumers mostly involves monetary transactions, some elephant owners may transfer ivory to relatives and friends for in-kind and sentimental purposes. The width of the arrows represents the proportional volume of activities.

Figure 3. Ivory supply from elephant owners in Thailand is driven by multiple factors at each step. The financial needs of elephant owners have a strong effect on decisions related to tusk harvesting and use. Tusk use and sale destination are influenced by market factors (price and access). Other influences on ivory supply include elephant use and management, sentimental values, ivory beliefs, legal awareness and tusk forms.
