Responsible cotton supply chains begin at the source

Backed by the power of forensic science, SigNature® T molecular tags can be applied at the gin, allowing for cotton to be tracked and authenticated throughout the entire supply chain, from the raw fiber stage all the way to the retail shelf. SigNature T tagging protects the cotton supply chain by providing assurance of quality and provenance, and helps brands guarantee label claims with certainty.

For Pima fiber (genetically known as G. barbadense), we also conduct “fiberTyping” of the fibers to confirm they are truly Pima based on our patented DNA test.

Responsible sourcing eliminates issues facing the textile industry, such as conflict cotton and fiber substitution. Certainty is only a molecule away™.

Consumers want to know where their cotton products come from, and if they are made responsibly. Brands often make product claims, such as "Grown in the USA", sustainable and ethically-sourced, or 100% Egyptian or Peruvian, how can we really know if these claims are being met?

Molecular tagging and DNA testing means that when something says it is made with 100% American grown cotton, or products made in a specific country, it is. The SigNature T System helps to provide certainty in supply chains.

To ensure your product is 100% pure, Applied DNA Sciences, Inc. provides fiberTyping®: a DNA test used to verify ELS Pima content. In textile supply chains, substitution takes place when Pima is replaced or blended with upland. Watch was we explain the process in order to avoid counterfeiting. To learn more visit

Through a groundbreaking DNA tracking system, we are able to verify PimaCott as the world's only Pima cotton from crop to consumer. By using fiberTyping®, Applied DNA Sciences, Inc., ensures that all cotton is in fact extra long stable Pima. Then, after marking it with SigNature®T, we are able to verify that our Pima stays pure across the supply chain.

Cannon Michael, Sixth-Generation Farmer at Bowies Farm, explains that although all Pima cotton starts out pure, only PimaCott is guaranteed to stay that way through a revolutionary DNA tracking system provided by Applied DNA Sciences, Inc. This tracking system verifies that our Pima is never blended or contaminated.

What is SigNature T?

SigNature T is a custom DNA molecule that bonds tenaciously to fibers at the source. Our fully-automated DNA Mixing and Distribution system ensures that fibers are tagged thoroughly. After tagging and compacting, bales are barcoded so that when a sample of fiber is submitted for authentication, it can be traced back to a particular bale number, providing absolute proof of provenance.

SigNature T DNA tags are designed to be compatible and stable in a wide range of textile substrates and manufacturing processes. This secure and cost-effective solution can help assure quality and provide forensic-level authentication in fiber, yarn, fabric and finished products.

SigNature T DNA provides the forensic power behind PimaCott™, the world’s first supply-chain-verified Pima cotton, as well as Homegrown™ source-verified upland cotton. Both of these brands are revolutionizing cotton purity. Over 100 million pounds of cotton has been marked. Home textile products made with PimaCott are now available in U.S. retail stores.

To achieve pima cotton certainty, SigNature T DNA tagging is complemented with fiberTyping®?

What is fiberTyping®?
fiberTyping is a patented DNA test that can be used to determine if a product contains the presence of Gossypium barbadense DNA (Extra Long Staple), Gossypium hirsutum DNA (Upland), or a blend of both.

fiberTyping is a powerful tool to help the cotton industry ensure that products labeled as 100% ELS, or 100% Pima, are compliant with label claims.
