Why Is Cashmere So Expensive?

The Price Tag Makes You Hesitate. Here's Why You Shouldn't Dismiss It.

You've probably stood in a shop, held a cashmere sweater, checked the price tag, and put it back. Or you've browsed online, seen a number north of £200, and thought: is this justified, or is it just branding?

It's a fair question. Understanding why cashmere is so expensive requires tracing the full supply chain — from a goat standing in a frozen desert in Inner Mongolia to a finished garment on your shelf. When you follow the economics, the price stops looking arbitrary and starts looking like the natural consequence of scarcity, geography, and biology.

This article breaks that chain down, link by link.

It Starts with the Goat — and Geography

Cashmere doesn't come from sheep. It comes from the undercoat of specific breeds of goat, primarily Capra hircus, that have adapted to extreme cold climates. The finest cashmere in the world comes from regions where winter temperatures regularly drop to -30°C or below.

Inner Mongolia — particularly the Alxa (Alashan) region — produces fibre that consistently grades at the finest end of the spectrum, typically 14 to 15.5 microns in diameter. The extreme continental climate is the reason: bitterly cold, dry winters force the goats to grow an exceptionally dense, fine undercoat as insulation. Milder climates produce coarser fibre because the goats simply don't need as much protection.

This isn't a marketing story. It's biology. The harsher the environment, the finer the undercoat.

The Yield Problem: One Goat, One Sweater

Here's the single biggest reason cashmere is expensive: a single cashmere goat produces only about 100 to 200 grams of usable undercoat fibre per year. After dehairing — the process of separating the fine undercoat from the coarser outer guard hair — the usable yield drops further.

To put that in perspective, a single cashmere sweater requires the annual yield of approximately three to five goats. A sheep, by comparison, produces several kilograms of usable wool per year. A single sheep can yield enough wool for multiple garments.

This scarcity is not artificial. You cannot speed up a goat's biology. You cannot make them grow more undercoat. The yield is what the yield is, and it sets a hard floor on the price of raw cashmere fibre.

Hand-Combing vs. Shearing: Why Collection Method Matters

The traditional and highest-quality collection method is hand-combing. During the spring moulting season, herders comb the loose undercoat from the goat's body by hand. This is slow, labour-intensive work — it takes significant time per goat — but it produces the cleanest separation of fine undercoat from coarse guard hair.

Shearing is faster but produces a mixed fibre that requires more mechanical dehairing. This process can damage the delicate undercoat fibres and typically results in a lower quality yield.

In the Alxa region of Inner Mongolia, hand-combing remains the dominant collection method. This adds labour cost at the very first stage of the supply chain.

The Dehairing and Sorting Process

Raw cashmere arrives at processing facilities as a mix of fine undercoat, coarse guard hair, and natural debris. The dehairing process — separating the two fibre types mechanically — is one of the most technically demanding steps in cashmere production.

Modern dehairing machines can differentiate fibres by diameter, but the process is slow and must be calibrated carefully to avoid damaging the fine fibres. After dehairing, the cashmere is sorted by colour, fineness (micron count), and staple length.

This sorting determines the grade:

Grade A fibre commands a significant premium over Grade B or C because it's softer, lighter, and more durable. The finer the fibre, the more it costs per kilogram at every stage.

China Produces Most of the World's Cashmere — But Not All of It Is Equal

China produces approximately 70% of the world's raw cashmere, with Mongolia contributing roughly 20%. The remainder comes from Afghanistan, Iran, and smaller producers.

But "Chinese cashmere" is not a single quality category. Fibre from the Alxa desert region of Inner Mongolia consistently grades finer than fibre from less extreme climates within China. Origin within the country matters enormously.

This is why single-origin sourcing is meaningful in cashmere — the same way single-origin matters in coffee or wine. Knowing which region the fibre came from tells you something verifiable about its quality, because climate and geography directly determine fibre diameter.

The Manufacturing Markup Is Smaller Than You'd Think

Once the sorted fibre reaches a knitting facility, it's spun into yarn and knitted into garments. These manufacturing costs — spinning, knitting, finishing, quality control — are a real part of the price, but they're not the dominant driver.

The dominant cost driver is the raw material. When your raw fibre costs many times more per kilogram than sheep's wool, and you need the annual yield of multiple goats for a single sweater, the maths produces a high-cost garment before you've spent a penny on design, marketing, or retail overhead.

Brands that charge £50 for a "cashmere" sweater are almost certainly using Grade C fibre, blending cashmere with cheaper fibres, or both. The raw material alone for a genuine Grade A cashmere sweater costs more than their retail price.

What About the Cheap "Cashmere" You See Everywhere?

This is the elephant in the room. If cashmere is so expensive to produce, how are some retailers selling cashmere sweaters for under £80?

Several possible explanations:

Lower grade fibre. Grade C cashmere (19+ microns) is significantly cheaper than Grade A. It's still technically cashmere, but it's coarser, less soft, and pills more aggressively.

Blending. Some garments labelled "cashmere" contain as little as 5-10% actual cashmere fibre, blended with cheaper wool, synthetic fibres, or yak hair. Labelling regulations vary by market, and enforcement is inconsistent.

Shorter staple length. Cheaper cashmere often uses shorter fibres, which are weaker and pill faster. The garment feels soft initially but degrades quickly.

Recycled or reclaimed fibre. Some low-cost cashmere uses mechanically shredded and re-spun fibre from discarded garments. This produces shorter, weaker fibres.

None of these are necessarily dishonest — if the label accurately states the composition. The problem is that many consumers buy cheap "cashmere" expecting Grade A quality, get disappointed after a few wears, and conclude that cashmere isn't worth the money. It is worth the money — they just didn't get actual premium cashmere.

The Bottom Line

Cashmere is expensive because the raw material is genuinely scarce — one goat, 100-200 grams of usable fibre per year, hand-combed from animals living in some of the harshest climates on earth. The price is not a markup story. It's a supply story. When you understand this chain, you can make better decisions about which cashmere is worth buying and which is cutting corners you can't see on the label. At Vionisxy, we use exclusively Alxa-region cashmere that grades under 15 microns and verify it through SGS lab testing — because when the price is real, the quality should be provable.
