Evaluation Checklist
Use this checklist before specifying, buying, growing, or marketing an industrial hemp material. It is designed to expose the questions that generic “hemp is better” claims miss: the actual application, required performance, processing route, supplier evidence, regulatory context, test methods, commercial constraints, and fallback plan.

How to use it
Use the Checklist as a Gate, Not a Scorecard
A checked box means you have addressed the question—not that hemp is automatically the right choice. A project can score 100% and still conclude that a conventional material is the better fit. That is a successful evaluation.
1
Define the baseline
Start with the job the material must perform and the conventional option it would replace or compete against.
2
Ask for evidence
Use product data, test reports, certifications, EPDs, contracts, samples, and regulator guidance—not broad claims about hemp as a crop.
3
Record uncertainty
If a supplier cannot document a claim, mark it unresolved and treat it as a project risk rather than filling the gap with an assumption.
4
Keep a fallback
For deadline-sensitive work, identify an alternate material, supplier, or process before a single-source constraint becomes a schedule problem.

The end use is defined in measurable terms
Record what the material or product actually has to do: load, thermal target,
abrasion, dimensional stability, appearance, moisture exposure, service life,
food/contact requirements, wash cycles, fire performance, or another relevant criterion.
A real comparator has been selected
Name the conventional product or current specification. Compare equivalent
functions and units rather than comparing raw hemp fiber with an unrelated finished product.
Pass / fail criteria are written down before supplier selection
Establish which requirements are mandatory and which are preferences. This
prevents sustainability or novelty from quietly overriding a required technical specification.
The evidence needed for each major claim is identified
Decide whether you need a test report, product data sheet, EPD, LCA,
certification record, farm documentation, regulator guidance, sample testing,
or another source before accepting the claim.
Commercial constraints are included in the evaluation
Record target cost, MOQ, lead time, order frequency, available processing
capacity, transport, quality tolerances, warranty requirements, and supplier continuity.
A fallback material or supplier has been considered
If the project depends on a developing supply chain, decide in advance what
happens if the specified hemp material cannot meet quality, price, volume, or schedule.

Full fiber composition is documented
Record the percentage of hemp and every other fiber. Do not treat “contains
hemp” as equivalent to 100% hemp or assume a blend has the same end-of-life
profile as the plant fiber alone.
Fiber preparation and spinning route are known
Confirm whether the hemp is long-line, cottonised, otherwise refined, or
blended, and whether the yarn/fabric construction is appropriate for the intended product.
Production fabric has been tested for the target use
Request the tests that matter for the product—such as tensile or tear
strength, abrasion, pilling, dimensional change, colorfastness, moisture
behavior, or another end-use requirement—and record the method used.
Finishes and treatments are disclosed
Ask about dyes, softeners, enzymes, coatings, water repellents,
antimicrobial finishes, resins, and other treatments that may affect
performance, claims, care, or disposal.
Certification scope has been verified
If a supplier cites GOTS, OEKO-TEX, OCS, or another credential, verify
what the certificate covers: fiber content, processing, harmful-substance
testing, facility scope, transaction documentation, or another defined requirement.
Marketing claims are based on the finished textile
Avoid blanket statements such as “stronger than cotton,” “naturally
antimicrobial,” or “biodegradable.” Use product-specific evidence and
clearly defined comparators or disposal conditions.

The role of the hemp material in the assembly is explicit
Identify whether it is insulation, infill, finish, board, panel, aggregate,
reinforcement, or another component. Do not assume that a typical hemp-lime
infill wall is the primary structural frame.
Applicable building-code / approval route is confirmed
Identify the jurisdiction, occupancy, product/system documentation, required
tests, approvals, engineer or building-official review, and any fire,
thermal, moisture, or structural requirements before procurement.
Product-specific thermal and moisture data are available
Use declared or tested values for the selected product/system. Do not copy
conductivity, density, vapor, or moisture values from a different hemp-lime
mix, insulation product, or laboratory study.
Water-management and drying strategy are designed for this assembly
Confirm rain exposure, ground contact, capillary breaks, membranes, drying
sequence, ventilation, coatings, plasters, and finishes using the chosen
system guidance and hygrothermal design. Avoid universal “always use X” rules.
Installer / contractor requirements are known
Determine whether the selected system requires trained installers,
manufacturer procedures, mix-control records, sample panels, cure/dry
conditions, specialized equipment, or third-party inspection.
Carbon claims use product- or project-specific evidence
If embodied-carbon performance matters, request an EPD, LCA, or other
documented calculation with clear system boundaries. Do not assume every
hemp building product is “carbon negative.”

The governing performance requirement is defined
Identify the relevant strength, stiffness, impact, fatigue, temperature,
moisture, dimensional, fire, acoustic, surface, weight, or other requirement.
Do not select a natural fiber because of one raw-fiber property.
Fiber form and matrix are specified together
Record whether the reinforcement is short fiber, mat, woven, aligned,
pelletized, pre-commingled, or another form, plus the exact thermoplastic,
thermoset, or other matrix system.
Moisture and fiber-matrix compatibility have been evaluated
Natural fibers can interact strongly with moisture and may need drying,
coupling agents, treatment, coating, process changes, or design allowances
depending on the matrix and service environment. Verify rather than assume.
The manufacturing route is validated at the intended scale
Confirm temperature limits, moisture content, fiber dispersion/orientation,
tooling, cycle time, forming pressure, part geometry, scrap, and process
control using trial parts or pilot runs where appropriate.
The finished composite is tested under the applicable method
Use the ISO, ASTM, OEM, customer, or regulatory test methods that apply to
the finished material/part. Raw hemp-fiber data should not substitute for
testing the actual composite formulation and process.
End-of-life language reflects the complete composite
A composite containing hemp is not automatically biodegradable,
compostable, recyclable, or plastic-free. Review the matrix, additives,
coatings, available recovery route, and local infrastructure before making a claim.

Current cultivation rules have been checked for the exact location
Identify the authority, required licence or authorization, cultivar/seed
rules, field registration, testing, reporting, harvest, transport, and
permitted plant-part requirements that apply before purchasing seed or planting.
The buyer / processor and target specification are identified
Get the processor’s requirements for cultivar, stalk or grain quality,
moisture, harvest timing, bale or delivery format, contamination, storage,
and rejected-load criteria before designing the crop plan.
Cultivar choice matches the intended market and legal program
Confirm that the cultivar is permitted where required and suitable for the
intended fiber, grain, or other lawful industrial output. Use local trial
data and processor requirements where available.
Harvest, retting, storage, and transport logistics are confirmed
Match equipment and timing to the crop and buyer specification. Confirm
who owns or hires the equipment, how retting will be managed if applicable,
acceptable moisture, storage conditions, bale format, and delivery distance.
Agronomic assumptions use local evidence
Do not copy universal yield, irrigation, pesticide, fertilizer, rotation,
or soil claims from promotional material. Use extension guidance, local
field trials, agronomist input, soil tests, and the actual farm system.
The budget uses contracted or documented assumptions
Model seed, field operations, harvest, drying/retting, storage, transport,
testing, processing charges, rejection risk, and the actual buyer price.
Keep optimistic commodity-price or yield assumptions separate from the base case.

Supply-chain stages and geographic origin are documented
Record cultivation, primary processing, secondary processing, manufacturing,
finishing, and final assembly where those stages matter to traceability,
procurement, origin, carbon, labor, or certification claims.
Supplier evidence has been verified rather than copied
Check current certificates, test reports, EPDs, LCA reports, declarations,
standards, and document scope. Confirm that the evidence applies to the
exact product, facility, lot, or supply chain you intend to use.
Environmental claims are specific and substantiated
Avoid broad, unqualified claims such as “green,” “eco-friendly,” “zero
impact,” or “100% sustainable.” State the specific attribute, product or
system boundary, comparator, conditions, evidence source, and limitations.
Regulatory guidance has been checked in every target market
Environmental marketing, building products, textiles, packaging, food,
agriculture, imports, and product safety can be regulated differently.
Use the rules that apply to the actual product and jurisdiction.
The cost and schedule comparison uses equivalent scope
Include all relevant processing, freight, testing, certification, specialist
labor, installation, tooling, waste, lead time, replacement, and end-of-life
costs rather than comparing only headline material prices.
Unresolved assumptions are visible in the final decision
Separate verified facts from estimates, supplier representations,
engineering assumptions, marketing language, and unknowns. If a decision
depends on an unresolved point, assign an owner and a due date before approval.
Important: this is a decision-support checklist, not a certification
scheme. Completion does not mean a material is compliant, safe, sustainable, or
suitable. It means the project team has identified the questions that need evidence
and professional review.
