An inspection at the right moment, against the right standard, is the cheapest insurance a glove importer can buy - and most buyers either skip it or do it wrong. Here is how AQL sampling actually works in plain terms, when to inspect, what a glove-specific defect list looks like, and how to set inspection terms so a failed batch is the factory's problem to fix, not yours to discover at your customer.
Why Inspect at All - The Cost Asymmetry
Inspection is about a cost asymmetry: catching a defect at the factory costs cents, catching it at your warehouse costs a return and rework, and catching it at your customer costs the relationship. A pre-shipment inspection on a typical glove order costs a few hundred dollars; a rejected pallet at a retail DC or a safety failure in the field costs orders of magnitude more. Yet many buyers skip inspection to save the fee or to avoid offending the supplier. That is a false economy. The inspection is not an insult to a good factory - good factories expect it and pass it easily; it is the factories that resist inspection you most need to worry about.
AQL in Plain English
AQL - Acceptable Quality Limit - is the statistical sampling system (ANSI/ASQ Z1.4, formerly MIL-STD-105) that lets an inspector check a sample of your order and make a pass/fail decision about the whole lot, without opening every carton. The system defines, for your lot size and chosen inspection level, how many pieces to randomly pull and how many defects are allowed before the lot fails. You do not need the maths - you need to know it exists and to specify the AQL level. The common consumer-goods standard is AQL 2.5 for major defects and 4.0 for minor (often written as 2.5/4.0), with 0 allowed for critical (safety) defects. That single line on your PO is what makes inspection objective rather than an argument.
Critical, Major, Minor - Classify Your Defects
AQL works by defect class, so you must define what counts as each for gloves. Critical defects render the glove unsafe or illegal - a cut-resistant glove below its rated level, a chemical glove that fails permeation, a sharp embedded object, a missing required marking; you allow zero of these. Major defects make the glove unsaleable or likely to be returned - wrong size, broken seam, holes, significant colour mismatch, peeling coating, wrong material. Minor defects are cosmetic and unlikely to cause a return - small loose threads, slight shade variation within tolerance, minor print misalignment. Write your own glove-specific defect classification and attach it to the PO, because the inspector will apply your list, and an undefined defect is an argument waiting to happen.
A Glove-Specific Defect Checklist
Generic inspection checklists miss glove-specific failures, so build one. For all gloves: correct size and size-mix per carton, dimensions within tolerance, correct material and colour against the golden sample, no holes or open seams, stitching density and seam strength, correct logo placement and quality, correct packaging and labelling, accurate carton counts and barcodes. By type: coated gloves - coating coverage, adhesion, no cracking, no thin spots; cut/chemical/thermal gloves - correct certified spec and present markings; leather gloves - hide consistency, no major scars in visible panels, Kevlar thread on welding gloves; hi-vis - fluorescent shade and reflective placement. Hand-feel and a wear-test on a few pairs catch things a visual check misses. The more specific your checklist, the more useful the inspection.
When to Inspect: DUPRO and Pre-Shipment
Timing matters as much as the standard. The two key inspection points are: during production (DUPRO), done when roughly 20-50% is made, which catches a systemic problem early enough to correct the remaining run; and pre-shipment inspection (PSI), done when 100% is produced and at least 80% packed, which is the final gate before the goods leave. For a first order with a new supplier, or a large or safety-critical order, do both - DUPRO catches the disaster while it is still fixable, PSI confirms the finished lot. For a trusted repeat supplier on a routine SKU, a PSI alone is often enough. Build the inspection point into your timeline so production is not held up waiting for the inspector.
DIY, Factory Self-Inspection, or Third Party
Three ways to inspect, with different credibility. Factory self-inspection (their QC, their report) is useful but not independent - they are marking their own homework. Your own staff or agent inspecting is independent but only practical if you have someone in-country. Third-party inspection firms - SGS, Bureau Veritas, Intertek, AsiaInspection/QIMA, V-Trust - send a trained inspector to apply your AQL and checklist and issue an independent report, typically USD 200-350 a day. For most importers, third-party PSI is the right default: independent, documented, and credible if you ever need to hold the factory to account. We welcome third-party inspection and publish our internal QC stages openly - see our cut-resistant standards guide for how rated gloves are tested.
Make Inspection Contractual, Not Optional
An inspection only protects you if the right to act on it is written down. Put it in your PO and contract: the AQL levels (e.g. critical 0 / major 2.5 / minor 4.0), your defect classification, the inspection point(s), who pays (you pay the inspector; the factory bears the cost of a re-inspection after a fail), and crucially the consequence of a fail - the factory reworks or replaces at its cost and the shipment is held until a re-inspection passes. Tie the final payment to a passed inspection (the classic 30/70 with the 70% due after PSI passes). Without that contractual hook, a failed inspection is just bad news you paid to receive; with it, it is the factory's problem to fix before they get paid. Our vetting guide covers structuring payment around inspection.
Our Honest Position on Inspection
We expect to be inspected and we would rather you did - a buyer who inspects is a buyer who will trust the result and reorder, and a passed third-party report protects us as much as you when a downstream customer questions quality. We publish our internal QC stages, we accept your AQL and defect list on the PO, and we are comfortable with final payment tied to a passed pre-shipment inspection. The factories that resist inspection or push back on AQL terms are telling you something; the ones confident in their work, like any serious manufacturer, treat your inspector as a normal part of doing business. Define your AQL, write your glove-specific defect list, inspect at the right moment, and make the right to act on a failure contractual - that is the whole discipline, and it is cheap.
Quote Comparison Welcome
If you already have a quote from another supplier, send it over with the spec sheet - we will quote against it line by line and tell you where we are cheaper, where we are not, and why. Most useful for buyers on order #2 or #3.
