Cashmere sweater grading separates premium knitwear from ordinary products. For B2B buyers, knowing these quality tiers helps you source better, price smarter, and protect your brand reputation. This guide explains the cashmere sweater grading system in plain terms.
What Is Cashmere Sweater Grading?
Cashmere sweater grading is the process of sorting raw cashmere fibers into quality tiers. Mills and manufacturers use this system to decide which fibers become luxury sweaters and which become budget blends. The grade depends on fiber length, fineness, color, and crimp.
Understanding cashmere sweater grading matters because not every cashmere garment offers the same value. A Grade A sweater feels softer, lasts longer, and pills less than a Grade C sweater. Therefore, buyers who know the tiers can negotiate from a position of strength.
Most suppliers use a simple A-B-C scale. However, some regions add subgrades such as A+ or B+. Always ask your factory for a fiber spec sheet before placing a bulk order.
The Three Main Cashmere Quality Grades
Manufacturers generally divide cashmere into three main grades. Each grade has a clear impact on hand feel, durability, and retail price.
Grade A Cashmere
Grade A cashmere comes from the finest undercoat fibers. These fibers measure 14 to 15.5 microns in diameter and reach 36 millimeters or longer. The result is a sweater that feels exceptionally soft and resists pilling.
Grade A fibers are usually white or light beige. Light colors dye evenly, so designers get accurate Pantone matches. This grade commands the highest raw-material price, but the finished product supports premium retail positioning.
B2B buyers targeting luxury markets should insist on Grade A material. It reduces returns, improves customer satisfaction, and strengthens brand equity.
Grade B Cashmere
Grade B cashmere falls between premium and commercial tiers. Fiber diameter ranges from 15.5 to 18 microns, and length is shorter than Grade A. The fibers may show more variation in color and crimp.
Sweaters made from Grade B cashmere still feel soft, but they may pill more quickly. They work well for mid-range brands that want a cashmere story without luxury pricing. Additionally, Grade B is common in blends where manufacturers mix cashmere with wool or synthetic fibers.
For B2B buyers, Grade B offers a practical balance. It lowers unit cost while keeping the cashmere label credible.
Grade C Cashmere
Grade C cashmere includes coarser fibers over 18 microns and shorter staples. This grade often comes from older goats, outercoat contamination, or mixed origins. The resulting yarn feels less soft and pills faster.
Grade C appears mainly in low-cost cashmere blends. Some products labeled “cashmere” may contain only 5% to 10% Grade C fiber. Buyers should request composition certificates to verify actual content.
This grade can work for entry-level promotional lines. However, it rarely satisfies customers who expect genuine luxury.
Key Metrics That Define Cashmere Quality
Cashmere sweater grading relies on measurable fiber traits. Understanding these metrics helps buyers compare quotes and avoid hidden quality drops.
Fiber Diameter
Fiber diameter is measured in microns. Thinner fibers feel softer and create smoother yarn. Grade A cashmere stays below 15.5 microns, while Grade C can exceed 18 microns. Therefore, diameter is the single most important softness indicator.
Fiber Length
Longer fibers spin into stronger, smoother yarn. They also resist pilling because fewer fiber ends protrude from the fabric surface. Grade A fibers are typically 36 mm or longer. Shorter fibers produce fuzzier, weaker knits.
Crimp and Color
Crimp refers to the natural wave in cashmere fibers. More crimp means better elasticity and loft. White fibers are most valuable because they accept dyes cleanly. Darker or discolored fibers may limit color options or require extra bleaching.
| Grade | Diameter | Length | Color | Best Use |
|---|---|---|---|---|
| Grade A | < 15.5 microns | ≥ 36 mm | White / light | Premium luxury lines |
| Grade B | 15.5 – 18 microns | 30 – 36 mm | Mixed | Mid-range brands |
| Grade C | > 18 microns | < 30 mm | Variable | Budget blends |
How Cashmere Grading Affects B2B Pricing
Raw cashmere prices vary sharply by grade. Grade A fiber can cost two to three times more than Grade C fiber. This difference flows directly into finished-garment pricing.
For example, a 100% Grade A cashmere pullover may wholesale between $45 and $75 depending on gauge and weight. A Grade B equivalent might wholesale between $28 and $48. Blends with Grade C cashmere can drop below $15 but sacrifice softness and longevity.
B2B buyers should align fiber grade with target retail price. Premium positioning demands Grade A. Value positioning can use Grade B or carefully disclosed blends. Moreover, always confirm grade in writing to prevent substitution during production.
Regional Differences in Cashmere Sourcing
Cashmere originates mainly from China, Mongolia, Afghanistan, and Iran. Each region produces fibers with distinct characteristics.
Chinese and Mongolian cashmere dominates global supply. Inner Mongolian fibers often reach Grade A quality due to cold climates and careful combing practices. Afghan cashmere tends to be slightly coarser but offers ethical and traceable sourcing stories.
Regional origin affects availability, lead time, and sustainability claims. Buyers interested in responsible sourcing can look for certifications from organizations such as the OEKO-TEX association. Additionally, traceable supply chains help brands meet growing consumer demand for transparency.

Final Tips for B2B Buyers
Use this checklist when sourcing cashmere sweaters for your next collection:
- Request fiber diameter and length specifications in writing.
- Ask for a composition certificate and lab test report.
- Compare swatches from at least two grades before deciding.
- Match fiber grade to your target retail price and brand promise.
- Confirm pilling resistance and care instructions for end customers.
- Verify supplier certifications for quality and sustainability claims.
Following these steps reduces risk and improves product consistency. Moreover, clear specifications make factory communication faster and more reliable.
