New Classification for Industrial Hemp Processing Pathways and Material Forms (Fiber/Hurd/Byproducts)
1. Scope
1.1 This classification standard establishes a harmonized framework for classifying industrial hemp materials based on both end material form and associated processing pathways, encompassing bast fiber, hurd (shives), and byproducts.
1.2 This classification covers industrial hemp applications relevant to fiber (FB), hurd, and byproduct fractions used across textiles, composites, construction, and related technical materials.
1.3 The examples for end use material forms are not intended to be all-inclusive but are included only as an aid in the understanding and comprehension of each type of classification.
1.4 This classification does not prescribe specific processing methods, equipment, or operating conditions, but rather provides a common structure for identifying and classifying material forms as they emerge from different processing pathways.
1.5 This classification excludes:
1.5.1 Cannabinoid extraction and pharmaceutical processing
1.5.2 Grain and seed applications intended for food, feed, or nutraceutical use
2. How the Guide Will Be Used
The proposed Guide will serve as a foundational reference document to:
• Illustrate common conversion and processing pathways for hemp materials across major application sectors;
• Support the development of future test methods and performance specifications for hemp-based products; and
• This Guide will not serve as a testing or specification document, but as a cross-reference and framework to ensure comparability and reproducibility in industrial hemp research and product development.
3. Intended Users
The primary users of this Guide will include:
• Researchers and universities conducting studies on hemp fiber and hurd processing, material characterization, and product development.
• Manufacturers and processors developing technical and industrial products incorporating hemp materials;
Testing laboratories and standards organizations applying or referencing ASTM and ISO methods for hemp evaluation
