Hemp Fiber: A Sourcing Guide

Start with what you need to buy: fiber for a mill, yarn for knitting or weaving, or finished fabric for a product. A company processing hemp stalks may serve a very different customer from a fabric supplier offering sample cuts.

This guide helps small brands and designers prepare a sourcing brief and use the directory. It does not rank hemp above other materials.

Properties

  • Fiber: request length, fineness, cleanliness, moisture and processing details; have your mill confirm compatibility.
  • Yarn: specify count, twist, blend and the intended knitting or weaving process.
  • Fabric: compare weight, width, construction, finish, shrinkage and sample handle.
  • Ask for product-specific results before making strength, antibacterial or UV-protection claims.

Applications

  • Garments: begin with a suitable finished fabric unless your team can manage textile development.
  • Bags and interiors: agree abrasion, seam and care requirements with your manufacturer.
  • Technical materials: distinguish bulk fiber and nonwovens from apparel-grade yarns and fabrics.
  • Approve the exact sample, not the fiber name alone.

Sustainability

  • Request growing origin, processing location, full composition and finishing information.
  • Textile Exchange's 2023 review identifies evidence gaps and cultivation and processing concerns; hemp is not automatically impact-free.
  • Do not turn crop carbon uptake into a claim that a finished garment is carbon-negative.
  • Check the whole product before making end-of-life claims, including blend fibers, dyes, coatings and trims.

Production Process

Processing matters to the specification

Textile Exchange describes multiple steps between growing hemp and producing a textile. Ask a prospective supplier which stages it performs, which are subcontracted and what specification it delivers. Its report also cautions that evidence for many sustainability claims remains limited. Read Growing Hemp for the Future (2023), especially sections 4 and 8.

Check what “hemp” means in the product

Request the complete fiber percentages for the exact product code. If your brief excludes cotton or synthetic fibers, state that explicitly; do not assume a hemp-labelled range meets that requirement. Ask separately about coatings and finishes.

Source-reviewed starting points

These records distinguish company role and product form. Inclusion is not a recommendation or confirmation of available stock.

  • HempFlax — Bulk technical hemp fiber. Technical fiber processor.
  • Bast Fibre Technologies — Processed hemp fiber for nonwovens. Technical fiber processor.
  • Hemp Traders — Hemp fabrics, yarns and bast fiber. Textile supplier and importer.
  • EnviroTextiles — Hemp and hemp-blend fabrics. Fabric developer, manufacturer and importer.

Use the same enquiry brief for every quote

  1. Describe your end product, required material form and any excluded ingredients.
  2. Give trial and production quantities with units, preferred colours and delivery destination.
  3. Ask for sample availability, minimum order per grade or colour, lead time and a technical sheet.
  4. Confirm the production and shipping locations, repeat-order availability and defect process.
  5. Request supporting documents for certifications or performance claims, with the exact product or facility scope.

Compare like-for-like specifications before comparing prices. Keep unconfirmed fields in your shortlist visible rather than filling them with assumptions.

Correction: the previous version included unsupported strength ratios, blanket biodegradability and carbon claims, and an unverified “top 10” supplier list. Those have been removed. Read our editorial standards.
