Goodwill Marketing Co., Ltd.

Founded in 1986, Goodwill Marketing Co., Ltd. began as a retailer for ANSAC’s (American Natural Soda Ash Corporation) soda ash.  In just a few short years, our consistent ability and commitment have led us to become ANSAC’s full authorized distributor in Thailand.  

Soda ash – or sodium carbonate (Na2CO3) – is an essential material widely used in the manufacturing of glass products, as well as other consumer products such as food additives, detergent, toothpaste and many others.  

As part of Weng Group, we truly understand the importance of quality-controlled storage and transfer of product along all steps of the supply chain.  Along with our sister company, Thepaporn Co., Ltd., (established to manage the handling of soda ash), we take full advantage of four warehouses throughout Thailand, located in Phra Nakhon Si Ayutthaya, Samut Prakan and Chonburi provinces.  Today, we handle and manage soda ash from the moment ANSAC ships reach Thailand to final delivery to customers nationwide. 

Our strong and long-lasting relationship with ANSAC, as well as constant focus on our key strengths allows us to provide a superior product with stability to our clients.  

  • Superior quality of product:ANSAC supplies the highest quality natural soda ash available in the world market. This creates an advantage in producing superior glass proudcts, as well as controlling production costs in the long run.
  • Dependability:As standard business practice, we invest in maintaining large amounts of reserve inventory to secure a long-term supply to our clients throughout all normal and extraordinary situations.  Moreover, the handling of soda ash by our sister company, Thepaporn Co., Ltd., gives us full control over the transfer, storage, and distribution of soda ash.  We are able to ensure untainted trans-loading, as well as guarantee cost-effective and timely delivery.  Simultaneously, the quality of product is also monitored and confirmed by third party organizations such as SGS and Intertek every step of the way.  

About ANSAC:  ANSAC is an American company and the largest soda ash exporter in the world.  ANSAC’s soda ash is processed from trona ore through four plants operating along the Green River Basin of Wyoming.  This area contains the largest reserves of naturally-occurring high quality trona on earth, with deposits estimated at 100 billion tons, which is enough to supply the world’s soda ash needs for many hundred years.
