Supply Chain Policy

Thailand Smelting and Refining Co., Ltd.

Part of the Supply Chain policy of Thailand Smelting & Refining Co Ltd (Thaisarco) is to avoid purchasing all Conflict Minerals and Metals from its supply chain.

Conflict Minerals and Metals are materials, which through their mining, production or supply have either knowingly or inadvertently been of benefit to illegal armed groups or are in any way contributing to conflict or human rights abuses such as:

All such materials are excluded from Thaisarco’s supply chain and therefore from Thaisarco’s products. Thaisarco’s LME (London Metal Exchange) registered tin brands, “Phuket”, and “Thaisarco” and all Thaisarco added value products can be categorized as conflict free.

Conflict Affected and High-Risk Areas (CAHRAs) are those defined by the Organization of Economic Co-operation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas Third Edition (OECD Guidance).


In particular, Thaisarco’s policy to maintain conflict free status in the management of its supply chain is as follows :-

1. The policy is to purchase materials only from reputable suppliers with whom long relationships have been established or on whom adequate due diligence in terms of ‘know your counterparty’ protocols can be carried out. Supplies may be as tin ore (concentrate), crude or unrefined tin, refined tin metal, including that from LME warehouses, and a variety of secondary or intermediate products.
2. In all cases due diligence will be conducted on the supplier and supply chain to ensure that the supply is genuine, legitimate and does not in any way contribute to conflict or human rights abuses. If any supplier is unwilling to work with Thaisarco on how to remediate or mitigate, then Thaisarco may consider terminating with the counterparties whose identify that they are sourcing from, or linked to, any party committing serious human rights abuses.
3. Thaisarco complies at all times with both national and international law relating to Conflict Minerals, including UN Security Council Resolutions and the US Dodd Frank Act.
4. Thaisarco conforms to OECD Due Diligence for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, and the Responsible Minerals Initiative (RMI) Assurance Process Tin and Tantalum Standard. This includes the OECD 5-Step framework as applicable to the RMI.
5. Thaisarco incorporates third party audits into the supply chain as part of maintaining its status as a Responsible Minerals Assurance Process Conformant Smelter under RMI.
6. Thaisarco uses supply chain traceability schemes such as iTSCi tagging scheme, US and UN sanctions list for individual or entity who may involve with money laundering, non-payment of fees or taxes etc. to help ensure transparency in the supply chain.
7. Thaisarco personnel will make selected supplier site visits on a regular basis for audit purposes and to test plausibility.
8. Thaisarco has a risk management strategy as defined by the OECD Guidance and tracks the performance of risk mitigation. These strategies include suspending or terminate supplies in the event that unacceptable practices are identified.

Thaisarco’s policy is to differentiate itself by offering its customers and trading partners conflict free metals and products, so that the final customer in the supply chain can be confident its products are produced from metals which are conflict free.
