The first hemp fiber built to the HFGA US Textile Standard
Imperium is Heartland India's first producer compliant with the HFGA US Hemp Textile Standard. Carrying a full Digital Product Passport from Carbon Report that traces every lot from farm to yarn to fabric.
In India
The first fiber producer in India compliant with the HFGA US Hemp Textile Standard.
Apparel grade
Blend and cottonized hemp fiber, graded for cotton-system spinning.
Full DPP
A Digital Product Passport on every lot, unbroken from the field to finished textile.
What HFGA-TX-US-01 sets
The HFGA US Hemp Textile Standard is a technical standard from the Hemp Fiber and Grain Association that defines how US-grade industrial hemp bast fiber is graded and documented for textile use: three fiber grades, permitted retting methods, a restricted-substance list, and field-to-bale traceability, with the test methods and sampling that verify all of it.
Fiber grades
Three measured grades, TX-A to TX-C, by fineness, length, strength, and cleanliness.
Retting methods
Field, tank, enzymatic, or steam, declared per lot, chlorine-free.
Restricted substances
PFAS, glyphosate, chlorine, formaldehyde, and heavy metals held to strict limits.
Field-to-bale traceability
An unbroken record and lot ID from the standing crop to the baled fiber.
Three fiber grades
The grades aren't a quality ranking, each is a different fiber for a different spinning process. TX-B is wet-spun long-line; Imperium produces TX-A for cotton-system spinning.
Blend / short line
Fineness 6.1–12.0 dtex · 25–45 mm · tenacity ≥ 35 cN/tex · shive ≤ 3.0%
Typical use, Cotton-system blends, cottonized fiber
Long line
Fineness ≤ 6.0 dtex · 45–120 mm · tenacity ≥ 45 cN/tex · shive ≤ 1.0%
Typical use, Wet-spun long-line yarns, a different process and product
Technical nonwoven
Fineness ≤ 25 dtex · ≥ 15 mm · tenacity ≥ 25 cN/tex · shive ≤ 6.0%
Typical use, Needle-punch felt, composites, insulation
A Digital Product Passport,
farm to fabric
Every conforming lot carries an unbroken record. Five checkpoints, one lot ID, so a finished textile resolves all the way back to the field it grew in.
Farm
USDA-equivalent licence, certified seed lot, parcel geolocation, and a pre-harvest cannabinoid test, logged against every lot before a single stalk is cut.
Retting
Method and degree recorded (field, controlled-tank, enzymatic, or steam) with effluent captured. No chlorinated agents, ever.
Decortication & grading
Line fiber decorticated below 120°C to preserve tenacity, then graded and lab-tested for fineness, length, and strength to Grade TX-A.
Yarn
Spun from graded fiber, with a signed chain-of-custody transfer and a mass balance that reconciles input straw to output fiber within ±3%.
Fabric
Woven or knit with the lot ID intact, so a finished textile resolves all the way back to the field it grew in.
Clean by standard
The restricted-substance list isn't a marketing promise. It's a tested requirement of the standard.
No PFAS
Total organic fluorine under 20 mg/kg, no “forever chemicals.”
No pesticides off-label
Only EPA-labeled inputs; residues within EPA tolerance for hemp.
No glyphosate
Pre-harvest desiccants, glyphosate included, are prohibited outright.
No chlorine bleaching
Peroxide or ozone only. Chlorinated agents disqualify the lot.
Formaldehyde ≤ 16 mg/kg
Free and released formaldehyde held to a strict ceiling.
THC compliant
≤ 0.3% dry weight in feedstock; not detected in delivered fiber.
What compliance means
Under HFGA-TX-US-01, conformity is a property of tested material, not a company badge. Each claim names the standard, its version, the grade, and a specific verified lot, so what you read is exactly what was tested.
Permitted product claim
Imperium Fiber is registered to HFGA-PCP-…, declaring conformity to HFGA-TX-US-01 v1, Grade TX-A, verified lot HFGA-…-2026-…
The claim resolves to a lot and a Lot Verification Record, the same evidence a brand's due-diligence team would audit.

Does Supima Hemp Shed Microplastics?
No. Supima hemp is US-grown hemp with Supima cotton, so it has no polyester filament to shed. Plant-fiber lint in laundry is not plastic shedding.
Is Supima Hemp a Natural Alternative to Polyester?
Yes. Supima hemp is a natural alternative to polyester for sheets and towels: cellulose inputs, no plastic filament, and no polyester microplastic shed.
Supima Hemp Sheets Without Plastic Shedding
Supima hemp sheets are US-grown hemp and Supima cotton. With no polyester filament in the yarn, they do not bring plastic shedding to the bed.
