Where Does Cashmere Come From

The Economics of a Fiber That Costs More Than Gold by Weight

Cashmere comes from the soft undercoat of the Capra hircus goat, specifically breeds like the Changthangi goat in the Tibetan plateau and the Inner Mongolian goat. One goat produces roughly 150 to 200 grams of usable fiber per shearing, and that's the entire bottleneck. Most of the guard hair — the coarse outer coat — gets sorted out during processing, which is why yield is so low. I've dealt with buyers who expected $40 a kilogram for raw cashmere and couldn't understand why they were being laughed out of the market. Raw, dehaired cashmere in bulk currently trades somewhere in the $80 to $150 per kilogram range depending on fiber diameter, origin, and season of the shear. The fine fiber drops below 19 microns commands the premium. Anything above 23 microns is really going into blends or lower-grade products and it pills like nobody's business.

Where Does Cashmere Come From Geographically

China and Mongolia dominate production. Mongolia alone accounts for roughly 60 percent of global raw cashmere output, mostly from their semi-nomadic herds on the steppe. China's Inner Mongolia and Tibet regions handle the rest, along with significant processing operations in Inner Mongolia's Zhurihe and Qingzhen districts. Iran, Afghanistan, and parts of Central Asia like Kazakhstan contribute smaller volumes, mostly from dual-coated breeds managed by pastoral families. Here's something the marketing departments never mention: the "Pashmina" label you see on every online retailer is just a regional naming convention from Kashmir. It's still cashmere fiber, usually hand-combed from the Changthangi breed at elevations above 4,000 meters. The fineness can hit 12 to 14 microns because of the extreme cold these goats endure, but calling it "Pashmina" instead of "cashmere" lets retailers markup the price by 300 to 400 percent on the same raw material. The collection process itself is brutal and seasonal. Goats are typically combed, not shorn, during their spring molt when the undercoat loosens naturally. Hand-combing takes about 10 to 15 minutes per goat and yields slightly finer fiber than mechanical shearing because you can selectively gather only the softest undercoat. Machine-shorn material tends to include more guard hair and contamination from dirt and vegetable matter. I had a supplier once try to pass off machine-harvested fiber as hand-combed and the micron readings were off by 4 microns — a huge difference that you can feel immediately between your fingers.

The Processing Pipeline Nobody Talks About

Raw cashmere fiber comes out contaminated with dust, dirt, lanolin, and guard hairs. The dehairing process uses a series of rotating drum screens that separate fibers by diameter. This is mechanical, not chemical. The equipment is expensive and most smaller producers in Mongolia ship their raw fiber to China for processing because the dehairing infrastructure doesn't exist at scale in Ulaanbaatar. After dehairing, the fiber goes through carding, combing, and then spinning. The spinning part is where a lot of quality gets lost. Cashmere is notoriously difficult to spin because the individual fibers are short — typically 30 to 40 millimeters — and lack the friction needed to hold together during high-speed spinning. Manufacturers often blend in a small percentage of longer fibers or use lower spindle speeds, which slows production considerably. A typical ring-spinning setup might run at 800 to 1,200 revolutions per minute for cashmere versus 2,000 to 3,000 for wool. That's a major throughput constraint. Then there's the dyeing stage. Cashmere takes dye beautifully because of its porous cuticle structure, but it's also extremely sensitive to agitation. The fiber swells when wet and the scales open up, which means any mechanical stress during dyeing causes felting and shrinkage. I worked with a mill that tried to run cashmere through a high-temperature jet dyeing machine and lost nearly 18 percent of the batch to felted clumps. They switched to a low-tension overflow dyeing system and the yield recovery jumped to 96 percent, but the cycle time doubled from about 90 minutes to roughly three hours.

There's also the issue of origin fraud. A lot of cashmere labeled as "Mongolian" or "Tibetan" is actually blended with cashmere from other origins or mixed with lower-grade fiber and the labeling still passes customs inspection because the testing standards for fiber content are notoriously loose. Gas chromatography and isotope ratio mass spectrometry can trace the geographic origin of the fiber by analyzing the strontium and oxygen isotope ratios in the keratin, but very few buyers actually request this testing. It costs about $200 to $400 per sample and most purchasing decisions are made on price alone.

What You Actually Feel When You Touch It

The difference between genuine cashmere and cheap imitations isn't subtle once you know what to feel for. Real cashmere has a slight slip or glide against your skin — it's not sticky or resistant like cotton or wool blends. It should feel cool to the touch initially and then warm up quickly against your body. That's the insulation property of the trapped air within the fiber structure. If you rub a piece of cashmere between your fingers and it feels scratchy or abrasive, it's either too much guard hair or it's not cashmere at all. Polyester blends and acrylic "cashmere" feel warm but plasticky and tend to generate static electricity. Genuine cashmere generates almost no static because of its natural moisture regain of around 15 percent, which is significantly higher than synthetic fibers. The pilling question is unavoidable. Cashmere pills, period. It's not a defect, it's a physical property of short, fine fibers that get agitated. What separates good cashmere from bad cashmere isn't whether it pills — it's how easily the pills come off and how fast they reform. A well-spun, properly carded cashmere garment will pill but the pills sit on the surface and brush away easily. Poorly processed cashmere pills and the pills tangle into the fabric matrix, which is when it looks worn and shabby. I once spent an afternoon brushing down a supposedly luxury cashmere sweater from a well-known brand and it went from looking like a bird's nest to looking pristine in about twelve minutes using a simple fabric shaver. That garment was 23-micron fiber blended with 15 percent nylon for "durability," which is code for the manufacturer knew it would pill badly and was trying to compensate.

Practical Buying Advice

Check the micron count if the supplier provides it. Below 19 microns is luxury grade, 19 to 21 is mid-range, and above 23 is entry level or blend territory. Look for single-ply construction in lighter weights — two-ply or multi-ply yarns are often used to mask lower fiber quality by adding thickness without adding fineness. The weight per square meter matters too. A genuine cashmere jersey should feel substantial but not heavy. If a sweater claims to be 100 percent cashmere and costs under $80 at retail, something in the supply chain is either heavily diluted or mislabeled. Keep in mind that cashmere doesn't last forever no matter how you care for it. The fibers degrade with repeated washing and exposure to light. A well-made cashmere garment will give you five to eight years of regular wear with proper care, which means hand-washing in cold water with a pH-neutral detergent, laying flat to dry, and storing folded rather than hung. Hanging a cashmere sweater will stretch it out permanently because the fiber has no memory recovery like elastic materials.
