Tejing Vietnam has consistently acquired advanced technologies in equipment and processes combining them with quality raw materials and human resources second to none.

The combination of high technology support, vigorous management, stable sales network, powerful financial support, resource advantages, superior quality, competitive price, excellent team-work and considerate services makes Tejing Vietnam second only to China in the Southeast Asian tungsten industry.

The annual capacities of our main products are as follows:

APT 3000 MT
Blue Tungsten Oxide 2200 MT
Tungsten Trioxide 2200 MT
Tungsten Metal Powder 800 MT
Tungsten Carbide Powder 800 MT
Cast Tungsten Carbide 300 MT

The Lab:

The lab of Tejing Vietnam is fully equipped to analyse not only the input raw material but also the final products. Additionally, during every phase of production, chemical elements such as WO3, Mo, NH3, NaOH, Cl are analysed promptly to make sure all have achieved the requirements specified. This analysis is done to control the processes, increase production capacity and maintain the quality of product.

The lab is divided into different units to assure the accuracy of the testing result. The lab has a total of 7 units:

  • 1 unit for raw material testing
  • 1 unit for production control
  • 4 units for testing output products including APT, BTO, YTO, W2C
  • 1 unit for testing output products of W and WC

The Atomic Absorption Spectrophotometer is used to analyze elements such as Na, K, Ca, Pb, Cu, etc. The Spectrometer is used to analyse many elements at the same time, such as Cd, Al, Bi, Sb, Mn, Fe, V, Ti, Si, Mg, Co, etc. The VIS spectrophotometer is used to determine elements such as WO3, P, S, Mo, Sb, etc. Average particle size testing device or laser granularity analysis instrument are used for testing the grain size of products.

Many important elements (such as As, -NH4, etc.) which influence environmental issues are tested carefully and adhere to strict protocol in an effort to make sure that the discharged materials are within the parameters and meet the requirements established by local government.

Conflict Minerals Policy of Tejing(Vietnam)Tungsten Co.,Ltd.


The purpose of Tejing’s Conflict Minerals Policy

Columbite-tantalite (coltan), cassiterite, wolframite and gold, or their derivatives, including tantalum, tin, and tungsten, originating from the Democratic Republic of the Congo (DRC) and adjoining countries are sometimes mined and sold by armed groups to finance unfair labor practices or human rights violations. Some of these minerals and/or derivatives can make their way into the supply chains of the products used around the world. It is the policy of Tejing to avoid tungsten that directly or indirectly finance or benefit armed groups from conflict-affected regions. Tejing (Vietnam) Tungsten is committed to sourcing components and materials from companies that share our values around human rights, ethics and environmental responsibility and taking all steps to comply with “the Dodd-Frank Act” legislation and implementing a comprehensive due-diligence process to meet our obligations.


铌钽锰矿(钶钽铁矿),锡石,钨锰铁矿和金,或者他们的衍生物,包含钽,锡和钨,起源于刚果民主共和国(DRC)和毗邻的国家有时开采和销售的武装团体融资不公平的劳动实践或侵犯人权的行为。其中的一些矿物质或衍生物可以让他们的方式进入产品的供应链在世界各地使用。这是特精的政策以避免钨直接或间接提供资金或受益于受冲突影响地区的武装团体。 特精(越南)钨业致力于采购体现我们对人权,道德和环境责任价值观供应商的矿源以及采取一切措施遵守《多德-弗兰克法》法规并实施一个全面的审核程序以履行我们的义务。

What is Tejing (Vietnam) Tungsten Doing?

Tejing (Vietnam) Tungsten has always supported an industry-wide approach to addressing social responsibility issues throughout the supply chain mainly via company’s policy in controlling supply chain. Currently, Tejing is using two main types of material source:

• Tungsten Concentrate

• Tungsten Scrap

With raw materials, Tejing import from Cambodia, Thailand, Burma,Japan,Australia and Vietnam locally. One of most important point when establishing every new business is: we request customers to provide the documents showing the origin of the material in order to avoid the material from conflict areas in our production line. Moreover, Tejing is a TI-CMC member company and have already planned and been preparing necessary conditions to apply Conflict Free Smelter (CFS) program its production process to become the transparent tungsten manufacturer in using minerals.


特精(越南)钨业一贯支持通过公司控制供应链的政策来应对一个行业性的社会责任问题。 目前特精使用两种类型的原料:

 钨精矿

 钨废料

我们进口的原材料来自柬埔寨,泰国,缅甸,日本,澳大利亚,越南。最重要的一点是,每当我们建立一个新的业务,我们都会要求供应商提供原产地证,以避免冲突矿源进入到我们的生产线。 此外,特精已经规划和准备申请无冲突冶炼厂计划的必备材料,让特精成为生产过程中使用钨矿源变得透明化的钨生产商。

What Does Tejing (Vietnam) Tungsten Commit?

• Tejing apply minerals policy to control supply chain and cooperate with Suppliers to ensure the concentrates provided to Tejing are not conflict minerals.

• Tejing commit that all the materials – tungsten concentrate which used in Tejing production originated from the countries where not from Covered Countries..


 特精应用该矿源政策控制供应链以确保我们从供应商采购的钨精矿不是来自冲突矿源区。

 特精承诺所有的原料-适用于生产线上的钨精矿,原产地都不是来自“覆盖国家”。

Note:“Covered Countries”:

Democratic Republic of Congo,South Sudan,Rwanda,Burundi,Uganda,Zambia,Angola,Tanzania, the Republic of the Congo and Central Africa Republic.
