Our plant is our customer’s only warehousing and shipping point. We can handle a number of services for the customer including turn-key tolling where Custom Synthesis purchases the raw materials, manufactures the product, tests and packages the product and blind ships the material for our customer. We can offer a wide range of services to assist our customers in delivering their products to the market. Please contact us today if you have a tolling opportunity or if you are looking for a specialty ester. We look forward to hearing from you.
