You have seen the phrase "Grade A cashmere" on product descriptions, in brand marketing, and on labels. It sounds reassuring. It implies a quality standard has been met — that someone, somewhere, has evaluated this product and placed it at the top of a recognised scale.
Here is what most brands do not tell you: Grade A is the highest tier of the standard commercial cashmere grading system — but it is not the finest cashmere that exists. There is a grade above Grade A that most grading frameworks do not include, because the fibre it describes is so rare and so fine that it sits outside the commercial range entirely. And the Grade A label itself carries no legal enforcement at the retail level — any seller can apply it without consequence.
This article explains the complete grading system, what Grade A genuinely means and what it does not, and what questions to ask beyond the grade label to understand what you are actually buying.
1. The Cashmere Grading System — The Complete Picture
The cashmere industry uses a letter grading system — most commonly Grade A through Grade C or D — to classify raw fibre and finished products by fibre diameter. The grading is anchored to the ISO 17751 international cashmere standard, which sets ≤19 microns as the maximum diameter for certified cashmere. Within that 19-micron ceiling, the grades subdivide the quality range.
Before the letter grades, there is one category the standard grading system was not designed to accommodate:
P 12–14µm
Pashmina Grade — above and beyond the commercial grading system. The Changthangi goat of the Changthang plateau in Ladakh produces cashmere at 12 to 14 microns — finer than anything the Grade A to D framework was designed to describe. Governed by India's BIS IS 17269 standard and protected by a Geographical Indication tag since 2013, Pashmina grade is categorically different from commercial cashmere, not just a better version of it. At this diameter the fibre cannot be machine-spun — it requires hand-spinning on a traditional yindeer. It is not part of the A–D system because the A–D system begins where this fibre ends. This is the fibre Pashwrap sources exclusively.
A 14–16µm
Grade A — the finest tier of commercial cashmere. Grade A cashmere at 14 to 16 microns is genuinely fine — significantly softer than standard commercial cashmere and well below the skin prickle threshold for all but the most sensitive individuals. Sourced predominantly from well-managed Mongolian Gobi herds and the best highland Chinese production. Used by most European luxury brands in their premium lines and justifiably positioned as excellent quality. The gap between Grade A and Pashmina grade is real but narrower than the gap between Grade A and Grade C. A legitimate, high-quality product — the best the standard commercial system offers.
B 16–17µm
Grade B — good commercial cashmere. The mid-tier of commercial grading. At 16 to 17 microns, Grade B cashmere is genuinely soft — below the prickle threshold for most skin types — and represents honest, well-made commercial cashmere from Mongolia, China, and Iran. This is what well-priced mid-market department store cashmere should be. Not the finest available, but a real product at a fair price point. The majority of what an informed buyer would consider "good cashmere" sits here.
C 17–19µm
Grade C — standard commercial cashmere at the ISO limit. The lowest tier that qualifies as cashmere under ISO 17751. At 17 to 18 microns it sits near the prickle threshold — acceptable for most skin types but noticeable for sensitive skin on extended contact. At 19 microns it is at the absolute ceiling of the ISO definition and is essentially indistinguishable by feel from fine merino wool. This grade is the most widely produced, the most widely mislabelled, and the most frequently sold with Grade A marketing language attached to it.
D >19µm
Grade D — below ISO cashmere standard. Fibre above 19 microns does not qualify as cashmere under ISO 17751. Typically the coarser fibres from lower-altitude herds, improperly dehaired batches with guard hair contamination, or fibre from breeds that do not produce true cashmere undercoat. A product containing Grade D fibre cannot legally be labelled 100% cashmere in ISO-compliant markets. Frequently the content of unlabelled "cashmere blends" and low-price fake cashmere products.
📏 The Numbers Behind the Grades
The practical softness gap between grades is not linear — it is amplified by physics. Bending rigidity scales with the fourth power of fibre radius. Moving from Grade C (19µm) to Grade A (15µm) — a 21% reduction in diameter — reduces bending rigidity by approximately 60%. Moving further from Grade A (15µm) to Pashmina grade (13µm) — a 13% further reduction — reduces bending rigidity by an additional 40%. Each step down in micron count produces a disproportionately large improvement in perceived softness. The grade letters suggest equal steps. The physics describes unequal leaps.
2. What Grade A Cashmere Gets You — and What It Does Not
Grade A is a meaningful quality signal — when it is genuine and documented. Here is an honest breakdown of what the grade represents and where it falls short.
What Grade A genuinely means
✓
Fibre diameter of 14 to 16 microns — well below the prickle threshold, genuinely soft against sensitive skin for virtually all people.
✓
A fibre quality level that justifies the cashmere label — this is not a borderline product scraping through the ISO threshold. At 14 to 16 microns, Grade A is legitimately fine cashmere.
✓
The standard used by most credible European luxury brands — Mongolian-sourced Grade A cashmere is the backbone of the premium end of the commercial cashmere market.
✓
A product that will be soft on purchase and remain soft through careful washing — at this diameter, the fibres are fine enough that genuine Grade A cashmere does not require chemical softening to feel good.
What Grade A does not mean
✗
It is not the finest cashmere available. Pashmina-grade at 12 to 14 microns sits above the Grade A ceiling. The Changthangi fibre at 12 to 14 microns is categorically finer — and the bending rigidity gap between 14-micron Pashmina and 16-micron Grade A is perceptible to any attentive hand.
✗
It does not specify origin. Grade A cashmere can come from Mongolia, China, Iran, or any other region. The grade tells you the diameter. It says nothing about altitude, breed, traceability, or the conditions in which the fibre was produced.
✗
It does not specify processing method. Grade A fibre is typically machine-spun and machine-woven — which is perfectly legitimate for this diameter range. But it means the yarn structure and fabric character are different from hand-spun, hand-woven Kashmiri Pashmina at equivalent or finer diameter.
✗
It is not legally enforced at retail level. Any brand can call their product "Grade A cashmere" without documentation, penalty, or verification. The grade claim is only as trustworthy as the seller making it — which is why documentation matters.
✗
It does not guarantee the product is 100% cashmere. A blend containing Grade A cashmere fibre is still a blend. The grade describes the quality of the cashmere component, not whether other fibres are present. Always check for full fibre composition disclosure alongside any grade claim.
3. The Grade A Label Problem — Why Claims Without Proof Mean Nothing
Walk through any online marketplace and search "Grade A cashmere." You will find products at $30 and products at $500 both carrying the same label. At least one of those price points makes Grade A cashmere mathematically impossible to produce honestly — the input cost of genuine Grade A fibre and its processing exceeds what certain retail prices allow.
The problem is not that Grade A is a meaningless category — it is a real and useful quality descriptor when applied honestly. The problem is that nothing prevents its application dishonestly. There is no global authority policing grade claims at the retail level. There is no inspection regime. There is no penalty for calling Grade C cashmere "Grade A" on a product listing.
⚠️ When Grade A Is a Marketing Label, Not a Specification
A grade claim is only meaningful when accompanied by a laboratory test certificate from an accredited testing body — IWTO, SGS, Bureau Veritas, or equivalent — showing the mean fibre diameter in microns and the standard deviation of the measurement. The certificate should include the testing body name, the test date, and a sample reference number.
A product described as "Grade A cashmere" with no certificate is a marketing claim. It may be accurate — but without documentation, you have no way to verify it, and the seller has no reason to be precise about it. Always ask for the certificate. A seller with genuine Grade A cashmere will produce it without hesitation.
| What the seller says |
What it means without documentation |
What to ask |
| "Grade A cashmere" |
Marketing claim — could be any grade |
"Can you provide an OFDA test certificate showing the mean fibre diameter?" |
| "Finest Grade A" |
No industry definition of "finest Grade A" — purely marketing |
"What is the specific micron count, and what testing body certified it?" |
| "Premium Grade A cashmere" |
Same as above — "premium" adds nothing verifiable |
Same as above — ask for the number and the certificate |
| "14.5 micron cashmere — OFDA certified" |
Specific, verifiable, meaningful — this is a real specification |
Request the certificate to confirm — then trust it |
| "12–14 micron Pashmina, BIS IS 17269" |
Highest specificity — names standard, implies GI compliance |
Ask for OFDA certificate and confirm origin is Changthangi, Ladakh |
4. What Matters Beyond the Grade — The Full Quality Picture
Even when a Grade A claim is genuine and documented, the grade alone tells an incomplete story. The following factors matter alongside fibre diameter and can significantly affect the quality and longevity of the finished product.
📍 Origin matters. Grade A cashmere from a well-managed Gobi Desert herd and Grade A cashmere from an intensively farmed lower-altitude operation may test at the same mean diameter but have different fibre consistency, different guard hair contamination rates, and different long-term performance. A seller who knows their supply chain names the region and the herd type. "Grade A from Mongolia" is more informative than "Grade A cashmere" alone.
🧵 Processing method matters. Grade A fibre can be machine-spun or hand-spun — the diameter permits either. Machine-spun yarn is consistent and efficient. Hand-spun yarn at the finest diameters produces a different yarn character — slightly irregular, with a softer twist — that creates a distinctive fabric hand. Neither is wrong, but they produce different products. Know which you are buying.
📊 Standard deviation matters as much as mean diameter. An OFDA certificate shows both the mean fibre diameter and the standard deviation — the spread of fibre diameters across the sample. A low standard deviation means consistent fibre throughout the batch. A high standard deviation means wide variation — some fibres much finer than the mean, some much coarser. High standard deviation at Grade A mean diameter can result in perceptible prickle from the coarser outlier fibres, even when the average passes. Always ask for standard deviation alongside mean diameter.
🧶 Construction matters. A hand-woven Grade A cashmere scarf will outperform a machine-knitted Grade A cashmere scarf in drape, longevity, and pilling resistance — because woven construction resists the mechanical abrasion that causes surface pilling, regardless of fibre quality. Grade describes the fibre. Construction describes what was done with it.
🚫 Chemical softening conceals grade.strong> As noted throughout this series — chemical softening agents can make Grade C fibre feel like Grade A at point of purchase. A Grade A claim on a product that has been chemically softened is not necessarily dishonest about the fibre grade, but the softness you perceive is partly treatment and partly fibre. Genuine Grade A cashmere does not need softening treatment — the softness is in the fibre. Ask directly whether any softening agents have been applied.
5. Grade A vs Pashmina Grade — Why the Gap Matters
The most important context for understanding Grade A cashmere is understanding what sits above it. Pashmina-grade cashmere at 12 to 14 microns is not simply a better Grade A — it is a different category of product, produced from a different breed of goat, in a different geographic location, by a different process that cannot be replicated elsewhere.
14–16µm Grade A Finest commercial grade — excellent quality, legitimate premium
12–14µm Pashmina Grade Above the commercial system — requires hand-spinning, GI-protected
~60% Less bending rigidity Pashmina grade vs Grade A — the physics of the softness gap
500 years Craft tradition The hand-processing knowledge behind Pashmina that Grade A machine processing does not carry
For a buyer choosing between a genuine Grade A cashmere product and a genuine Pashmina-grade product, both honestly sourced and honestly priced, the choice comes down to this: Grade A offers excellent fibre quality with the efficiency and price accessibility of industrial processing. Pashmina grade offers the finest fibre on earth combined with a hand-processing tradition that no industrial system can replicate — at a higher price that reflects both the rarity of the fibre and the hours of skilled human work in every piece.
Neither choice is wrong. But they are not equivalent choices. Knowing the difference is what lets you make the one that is right for you.
Grade A is the best the commercial system offers.
Pashmina grade is what exists above the commercial system.
Both deserve the word "cashmere."
Only one deserves the word "Pashmina."
6. What to Ask Any Seller Who Claims Grade A
Five questions that separate a genuine Grade A product from a Grade A label applied for marketing purposes:
1️⃣ "What is the mean fibre diameter in microns — and can you provide an OFDA test certificate?" A specific number with a certificate is the only meaningful answer. Anything vaguer is a marketing claim.
2️⃣ "What is the standard deviation of the fibre diameter in the certificate?" Low standard deviation means consistent quality throughout. High standard deviation means the Grade A mean average hides coarser outlier fibres that may cause prickle.
3️⃣ "Where does the fibre come from — which region and which breed?" A seller who knows their supply chain names it specifically. "Grade A Mongolian Gobi cashmere" is a real origin. "Premium Grade A" with no geography is not.
4️⃣ "Is this product 100% cashmere or a blend?" Grade A describes the quality of the cashmere component. It does not confirm the product contains only cashmere. A "Grade A cashmere blend" is a blend — ask for full fibre composition with percentages.
5️⃣ "Has the product been treated with any softening agents?" Genuine Grade A cashmere does not need softening treatment. If the answer is yes, or evasive, the softness you feel may not survive washing.
