Final Inspection AQL for Cashmere Garments: What B2B Buyers Should Insist On

Introduction

For B2B buyers sourcing cashmere garments, the final inspection is your last line of defense against defects, delays, and reputational damage. Acceptable Quality Level (AQL) standards are the globally recognized benchmark for determining whether a shipment meets your specifications. Without a clear, contractually enforced AQL, you risk receiving products that fail to meet your brand’s quality promise.

At DONGXIAO Cashmere, a 23-year-old source factory based in Ordos, Inner Mongolia, we have completed thousands of final inspections for leading importers and brands worldwide. In this guide, we break down exactly what AQL standards you should insist on, how to set them in your contracts, and what to watch for during the inspection process.

What Is AQL and Why Does It Matter for Cashmere?

AQL (Acceptable Quality Level) is a statistical sampling method used to determine the maximum number of defective units allowed in a batch. For cashmere garments, where even minor flaws can compromise the luxury feel and durability, a stringent AQL is non-negotiable.

Key AQL Terms

• Critical Defect: Renders the product unsafe or unusable (e.g., holes, broken zippers, chemical odor).
• Major Defect: Affects functionality or appearance (e.g., color mismatch, pilling, loose seams).
• Minor Defect: Slight imperfection that does not affect wearability (e.g., small loose thread, slight shading).

For cashmere garments, the industry standard is typically:

• Critical: 0% (zero tolerance)
• Major: 1.0% AQL
• Minor: 2.5% AQL

However, premium brands often demand tighter levels: Major 0.65% and Minor 1.5%.

Why Cashmere Requires Stricter Standards

Cashmere fibers are delicate and expensive. Common defects in cashmere garments include:

• Pilling: Short fibers ball up on the surface.
• Color variation: Between pieces or within the same garment (due to dye lot inconsistency).
• Uneven knitting: Loose or tight stitches affecting drape.
• Seam slippage: Weak stitching that pulls apart under tension.
• Shrinkage: If not pre-shrunk properly, garments can shrink after first wash.

Because cashmere is a natural fiber (from the undercoat of cashmere goats), even the best raw material can have inconsistencies. That’s why a robust final inspection is vital.

How to Set AQL in Your Contract

When drafting your purchase order or quality agreement, specify:

1. Inspection standard: e.g., ANSI/ASQ Z1.4 (formerly MIL-STD-105E) or ISO 2859.
2. AQL levels: Critical 0%, Major 1.0%, Minor 2.5% (or your chosen levels).
3. Sampling plan: Single, double, or multiple sampling. Single is most common.
4. Defect classification: Detailed list of what constitutes critical, major, and minor defects for cashmere.
5. Inspection location: At the factory (pre-shipment) or at a third-party lab.
6. Who performs: You, your QC team, or an independent inspection company (e.g., SGS, Bureau Veritas, Intertek).

Sample Defect Classification for Cashmere Garments

Defect Type	Examples	AQL Limit
Critical	Holes, tear, chemical smell, broken zipper	0%
Major	Color mismatch >1 shade, pilling (grade 3 or worse), seam slippage >3 mm, shrinkage >5%	1.0%
Minor	Loose thread >2 cm, slight shading (within 1 shade), small knot in yarn	2.5%

The Inspection Process Step by Step

1. Pre-Inspection Preparation

• Confirm the inspection date at least 5 working days in advance.
• Ensure the factory has the approved sample, color card, and spec sheet.
• Randomly select samples from the finished lot. For a typical order of 1000 pieces, sample size is 80 (based on AQL 1.0/2.5, normal level II).

2. Visual Inspection

• Check each garment for color, knitting defects, stains, and overall appearance.
• Use a light box with D65 daylight simulation for color assessment.
• Measure dimensions against the spec sheet (chest, length, sleeve, etc.).

3. Functional Testing

• Zipper and button functionality: Open/close 5 times.
• Seam strength: Pull test (if applicable).
• Pilling resistance: Use a Martindale or ICI pilling box (grade 4 or higher is acceptable for premium cashmere).

4. Packaging Inspection

• Verify correct folding, polybag, and carton packing.
• Check carton markings, barcode scan, and quantity.
• Ensure inner and outer box labels match the packing list.

AQL Tables: How to Determine Sample Size

Use the standard AQL table (e.g., from ISO 2859-1). For a lot size of 501–1200 pieces, normal level II gives a sample size of 80. With AQL 1.0 (major), the accept number is 2 (if 3 or more major defects found, reject the lot). For AQL 2.5 (minor), accept number is 5.

Lot Size	Sample Size	AQL 1.0 (Major) Accept/Reject	AQL 2.5 (Minor) Accept/Reject
501–1200	80	2 / 3	5 / 6
1201–3200	125	3 / 4	7 / 8
3201–10000	200	5 / 6	10 / 11

Note: Critical defects always result in rejection if any are found.

Common Mistakes B2B Buyers Make

1. Not specifying AQL in the contract: Relying on verbal agreements leads to disputes.
2. Using the same AQL for all products: Cashmere requires stricter levels than cotton or synthetics.
3. Skipping pre-shipment inspection: Finding defects after shipment is costly and time-consuming.
4. Not testing for pilling: Cashmere pills more than other fibers; insist on a pilling test (e.g., 5000 cycles on Martindale).
5. Ignoring the factory’s QC track record: Ask for past inspection reports from third-party agencies.

Frequently asked questions about cashmere AQL inspection

Buyers, QC inspectors, and brand founders running pre-shipment checks on cashmere garments typically ask the same questions about AQL sampling, defect classification, and remediation. These quick answers cover the practical decisions B2B buyers face when accepting or rejecting shipments. To request a sample inspection plan with AQL tables, see our quality control guide.

What is AQL in cashmere QC?

AQL stands for Acceptable Quality Level — the maximum percentage of defective items in a lot that is considered acceptable as a process average in quality control sampling. In cashmere garment inspection, AQL is typically applied at three severity levels: critical defects (AQL 0, no defects allowed), major defects (AQL 1.0 or 2.5), and minor defects (AQL 4.0). A 1,000-piece cashmere order with AQL 2.5 major sampling means the inspector draws a random sample (typically 80 pieces for a 1,000-piece lot at General Inspection Level II), accepts the lot if 5 or fewer pieces in the sample have major defects, and rejects if 6 or more have major defects. The AQL level is a contractual specification between buyer and factory and should be agreed before production begins.

What AQL level is standard for cashmere garments?

The standard AQL level for cashmere garments is 2.5 for major defects and 4.0 for minor defects under General Inspection Level II sampling. Critical defects (such as broken needles left in the garment, sharp objects, or hazardous chemical residue) are AQL 0 — no critical defects are acceptable under any sampling plan. Premium retailers (luxury department stores, high-end boutiques) often specify stricter AQL like 1.0 for major defects. Budget retailers and mass-market programs typically accept 4.0 major. The AQL level reflects the buyer’s risk tolerance and downstream return-rate expectations — stricter AQL means fewer defects reach the customer but also higher inspection cost and more rejected lots.

What is the sample size for cashmere AQL inspection?

The sample size for cashmere AQL inspection depends on the lot size and the chosen inspection level. Under General Inspection Level II (the most common), a 500-piece lot gets 50 samples, 1,000 pieces gets 80 samples, 3,000 pieces gets 125 samples, 5,000 pieces gets 200 samples, and 10,000 pieces gets 315 samples. The inspector draws the sample randomly across the lot, inspects each piece against the defect classification list, and counts defects by category (critical, major, minor). The lot passes if defect counts are at or below the AQL acceptance number; rejects if any defect category exceeds the acceptance number. Reduced Inspection Level I is sometimes used for trusted supplier relationships; General Inspection Level III for stricter QC.

What counts as a major defect in cashmere inspection?

Major defects in cashmere garments are defined as defects that affect saleability, usability, or customer satisfaction but are not safety hazards. Common major defects in cashmere include: visible knitting defects (holes, dropped stitches, missed plies) that are 5mm or larger; oil stains or dirt marks that cannot be removed by normal laundering; visible mending or repair marks; color inconsistency within a single garment; broken buttons or snaps; missing care labels; pilling on a brand-new garment; yarn irregularities visible at arm’s length. The defect classification is specified in the buyer’s tech pack and AQL contract. Inspectors use the tech pack as the reference standard — what is not specified in the contract cannot be rejected as a defect.

Can a factory reject a third-party AQL inspection?

A factory cannot reject a third-party AQL inspection if the inspection clause is part of the purchase contract. Pre-shipment AQL inspection by a third party (SGS, Intertek, Bureau Veritas, Asia Inspection, TUV) is standard B2B practice and is typically included in the purchase order terms. Factories that refuse third-party inspection are a red flag for quality fraud. However, the factory can dispute specific defect classifications — if the inspector flags a defect the factory believes is within tolerance, the factory can submit evidence (photographs, measurements, comparison to approved pre-production sample) to challenge the call. The buyer’s final decision on disputed defects typically prevails if the contract is clear.

What happens if the AQL inspection fails?

If the AQL inspection fails (defect counts exceed acceptance numbers), the buyer has three options: (1) reject the lot and require the factory to rework or replace defective pieces at the factory’s cost; (2) accept the lot with a discount negotiated for the defects (rare in cashmere because defects are harder to remedy post-production); (4) request 100% inspection at the factory — the factory sorts through the entire lot and replaces or repairs all defective pieces, then a second AQL inspection is run on the reworked lot. Most cashmere contracts default to rework + re-inspection. The timeline for rework typically adds 7–14 days to the order. If rework fails, the buyer can cancel the order and recover deposit (subject to force majeure clauses).
