# How to Buy Industrial Hemp: A Sourcing Guide for Processors and Brands > What to specify, what paperwork to require, and where to buy industrial hemp fiber and grain from US growers — written for the purchasing side. *Published 2026-08-28 · tags: economics, policy* --- Most hemp content is written for growers. This one is written for the other side of the table: the processor, mill, brand, or manufacturer trying to buy industrial hemp and finding that suppliers describe the same material in five different vocabularies. The fix is to specify before you source. A purchase order that names a grade, a moisture ceiling, and a contamination limit gets consistent material. One that says "hemp fiber, best quality" gets whatever the seller has. Industrial hemp here means non-psychoactive fiber and grain varieties grown under the 2018 Farm Bill at or below 0.3% delta-9 THC — a regulated agricultural commodity, not a CBD or marijuana product. ## What You Are Buying When You Buy Industrial Hemp One hemp stalk yields several products, and they are not interchangeable. Bast fiber is the long outer fiber that spins and reinforces. Hurd is the woody core that goes into hempcrete, bedding, and board. Grain is a separate harvest entirely, sold for food and oil. Buyers who ask for "hemp" without naming the fraction receive quotes that cannot be compared against each other. Buyers who ask for decorticated bast fiber at a stated grade receive quotes that can. The association publishes an open [standards library](/standards) precisely so purchasing teams have neutral vocabulary to write into a contract. It is free to read and free to reference, and no membership is required to use it. One more distinction worth carrying into a first conversation: retted and unretted fiber behave differently in every downstream process, and so do field-retted and enzymatically treated material. Ask which one you are being quoted. A price that looks unusually low is often a different product rather than a better deal. ## Specify Before You Buy Industrial Hemp Three specification blocks handle most of the risk in a first purchase. ### Industrial Hemp Fiber: Grade, Length, and Contamination Name a grade rather than describing one. The [HFGA US/EU Decorticated Fiber Standard](/standards/decorticated-fiber-standard) defines three: DF-A high purity for cottonizing and spinning feed, DF-B standard commodity, DF-C technical for insulation and panel. For refined fiber going to a spinner, the [HFGA US Hemp Textile Standard](/standards/us-hemp-textile-standard) defines TX-A, TX-B, and TX-C by fineness, length, tenacity, and residual shive. The contamination clause is the one to enforce hardest. Farm bale wrap fed through a decorticator shreds into the fiber and cannot be separated afterwards — it ruins a lot for textile use and defeats any microplastic-free claim downstream. ### Industrial Hemp Grain: Moisture, Variety, and Food-Grade Handling For grain, specify moisture at delivery, the variety and seed lot, and whether the lot was handled to food-grade segregation. Hemp seed ingredients for human food sit under [FDA](https://www.fda.gov/food/food-ingredients-packaging) oversight, and a buyer sourcing for a food brand should confirm the handling chain before the first load rather than after. Dehulled and oil-press destinations carry storage expectations that fiber buyers never think about. Current pricing references are published on the [commodity pricing](/hemp-fiber-grain-commodity-pricing) page. ### Documentation That Should Come With Every Lot Require five items: the producer licence number, the pre-harvest cannabinoid test from a DEA-registered laboratory, the seed lot and variety, a moisture record, and a chain-of-custody document at each change of ownership. [USDA AMS](https://www.ams.usda.gov/rules-regulations/hemp) sets the licensing framework these records come from, and [USDA NASS](https://www.nass.usda.gov/) publishes production data worth checking before you commit volume. ## Where to Buy Industrial Hemp in the US Three routes, in rough order of volume. ### Buy Industrial Hemp Direct From Contracted Growers Contracting acres before planting is how serious volume gets secured. It gives the grower certainty and gives you a known variety, a known region, and first call on the crop. It also means committing before harvest, which is why most buyers start smaller. Contracts are also where specification actually bites. A grade written into a contract before planting shapes which varieties get seeded and how the straw is handled after harvest. A grade requested after harvest can only sort what already exists. ### Through Processors Holding Graded Inventory Decorticators and processors hold graded, baled inventory and can ship against a specification immediately. This is the fastest route to a trial quantity, and the right one for a first order where you are still validating the material in your own process. Ask what the processor's own incoming specification is. A decorticator running to a tight standard is filtering material before it reaches you, and that filtering is worth paying for on an early order. ### Free Introductions Through HFGA The Hemp Fiber and Grain Association introduces buyers to growers and processors at no charge — no commission, no listing fee, no membership. The network covers more than 12,000 contracted acres across 11 states, with 8,000+ tons of fiber and 1,200+ tons of grain processed as of 2024. International sourcing runs through the [US exports](/us-exports) program. Buyers evaluating a supplier's claims can check the [product registry](/registry), where a declared product maps to a grade of a published standard. And growers reading this from the other direction should start at [sell your crop](/sell-your-hemp-fiber-hemp-grain-crop) — the same introduction, from the supply side. --- Source: https://hfga.io/en/news/buy-industrial-hemp-sourcing-guide-for-buyers/ HTML version: https://hfga.io/en/news/buy-industrial-hemp-sourcing-guide-for-buyers/
