Final Random Inspection (FRI) happens _after_ production is 100% complete and at least 80% packed, using a statistical AQL sample to accept or reject the finished lot before shipment. Smart buyers sourcing from Bangladesh use **both**: inline to prevent defects becoming a full-order disaster, and final to verify the shipped goods meet the agreed quality standard. Relying on final inspection alone is the single most common quality mistake in apparel sourcing. Understanding when and why to deploy each inspection type is fundamental to protecting your order. This guide breaks down the differences, the AQL logic behind them, and how a [garment buying house in Bangladesh — complete guide](https://taeen.com.bd/garment-buying-house-bangladesh) sequences inspections to protect your delivery and your margin. ## The two inspections at a glance Both inspections use the same core quality language — AQL sampling, defect classification, and a written report — but they occur at different moments and answer different questions. - **Inline inspection** answers: “Is production going right, while we can still fix it cheaply?” - **Final Random Inspection** answers: “Is the finished, packed order good enough to ship?” They are complementary, not alternatives. Inline prevents problems; final verifies the outcome. ## What is inline inspection? Inline inspection (sometimes called DUPRO — During Production Inspection) is conducted while the order is actively being sewn, usually once the first 15–30% of units have come off the line. The inspector examines work in progress at the sewing and assembly stage before the bulk of the order is finished. ### What inline inspection checks - **Measurements against the spec sheet** — confirming the graded measurements match the approved sample within tolerance. - **Construction and stitching** — seam quality, SPI (stitches per inch), reinforcement at stress points. - **Fabric and colour** — shade consistency across rolls, no visible defects, correct GSM. - **Trims and accessories** — correct labels, zippers, buttons, and their placement. - **Workmanship on early output** — catching a systemic error before it repeats across thousands of units. ### Why inline matters so much The economic logic is decisive. If a cutting or stitching error is discovered at inline (when 20% is sewn), the factory can correct the process for the remaining 80% — a cheap, fast fix. If that same error is only discovered at final inspection, the entire order may already be defective, forcing rework, discount negotiation, or outright rejection with no time left before the ship date. Inline inspection converts a potential catastrophe into a minor course-correction. For an understanding of the sampling foundations behind this, see our guide on [AQL quality control guide](https://taeen.com.bd/blog/aql-quality-control-guide). ## What is Final Random Inspection (FRI)? Final Random Inspection is the verification checkpoint. It is performed when production is 100% complete and at least 80% of the order is packed into cartons. The inspector pulls a random, statistically determined sample from the packed cartons and evaluates it against the AQL standard agreed with the buyer. ### What FRI checks - **Overall quantity and packing** — carton counts, packing method, shipping marks. - **AQL defect sampling** — classifying defects as critical, major, or minor and comparing counts to the accept/reject limits. - **Final measurements** — on finished, pressed garments. - **Appearance and finishing** — pressing, folding, poly-bagging, hangtags, barcodes. - **Function tests** — zippers, snaps, stretch recovery, and any buyer-specified tests. FRI produces a clear pass or fail against the AQL limits, giving the buyer an objective, defensible basis to authorise or hold the shipment. ## How AQL sampling drives both inspections Both inspections rely on Acceptable Quality Limit (AQL) sampling — an internationally standardised method (ISO 2859 / ANSI-ASQ Z1.4) for inspecting a representative sample instead of every unit. The buyer sets AQL thresholds, commonly **2.5 for major defects and 4.0 for minor defects** on general apparel, with critical defects almost always set to zero tolerance. - **Critical defects** — safety or regulatory hazards (e.g. broken needles, harmful substances); zero tolerated. - **Major defects** — faults that would cause a customer to return the item; tightly limited. - **Minor defects** — small imperfections unlikely to affect sale; more tolerance allowed. The sample size and accept/reject numbers come from the AQL tables based on lot size and inspection level (Level II is standard). Getting these parameters right — and agreeing them in the PO — is essential before any inspection begins. ## Inline vs final: side-by-side - **Timing:** Inline = during sewing (15–30% complete); Final = after 100% production, 80% packed. - **Purpose:** Inline = prevent and correct; Final = verify and accept/reject. - **Cost of a catch:** Inline = low (fix the process); Final = high (rework or reject finished goods). - **Output:** Inline = corrective feedback to the factory; Final = ship / hold decision. - **Best for:** Inline = large orders, new factories, complex styles; Final = every order, always. ## When to use each — practical scenarios ### Use inline inspection when… - The order is large and a systemic defect would be expensive to rework. - You are working with a **new or unproven factory** where process reliability is unknown. - The style is complex — technical fabrics, difficult construction, tight tolerances. - Lead time is tight and there is no room for post-production rework. ### Rely on Final Random Inspection when… - Always — FRI is the non-negotiable last gate before shipment on every order. - The factory is well-known and reliable and the style is simple (FRI alone may suffice for low-risk repeat orders). - You need an objective, documented accept/reject record for the shipment. ### Use both (the recommended default) when… For most meaningful orders, combine them: inline to protect the bulk of production, final to verify the shipped result. This two-checkpoint approach is standard practice for buyers who cannot afford a failed delivery. It pairs naturally with a strong pre-order step — our [Bangladesh factory visit checklist](https://taeen.com.bd/blog/factory-visit-checklist-bangladesh) covers how to assess a factory's quality systems before you even place the order. ## Common mistakes buyers make - **Final-only inspection on risky orders.** Discovering a systemic defect at final, with no time to rework, is the classic avoidable disaster. - **Not agreeing AQL levels in the PO.** Undefined thresholds lead to disputes at the worst possible moment. - **Inspecting too early or too late.** Inline before 15% gives too little signal; final before 80% packed misses packing defects. - **Skipping the corrective loop.** An inline report is worthless if the factory does not act on it — follow-up is essential. - **Using the factory's own inspectors as the only check.** Independent, buyer-side inspection removes the conflict of interest. ## How a buying house sequences inspections for you Coordinating inspections across the production timeline — booking the inspector at the right completion percentage, agreeing AQL parameters, chasing corrective actions, and issuing the ship/hold decision — is exactly what a local sourcing partner manages day to day. A [garment buying house in Bangladesh](https://taeen.com.bd/garment-buying-house-bangladesh) provides independent, buyer-side inspectors physically present in the factory clusters, so your quality gates are enforced on the ground rather than negotiated over email after the goods are already made. This is the difference between a quality system on paper and one that actually protects your shipment. ## Frequently asked questions ### Is inline or final inspection more important? Final Random Inspection is non-negotiable on every order, but inline inspection is what prevents defects from becoming a full-order failure. For any significant or higher-risk order, both are recommended — they answer different questions. ### At what production stage is inline inspection done? Typically when 15–30% of the order has been sewn — early enough to correct the process for the remaining units, but late enough to see representative output. ### What AQL levels are standard for apparel? Commonly 2.5 for major defects and 4.0 for minor defects, with zero tolerance for critical defects, using General Inspection Level II. These should be agreed in the purchase order. ### Can I skip inline inspection to save cost? Only on low-risk repeat orders from a proven factory. On large orders, new suppliers, or complex styles, skipping inline is a false economy — a single systemic defect caught only at final can cost far more than the inspection. ### Who should perform the inspections? Independent, buyer-side inspectors — not the factory's own QC alone — to remove the conflict of interest. A buying house provides this independent presence in the factory clusters. ## Related Guides - [Garment Buying House in Bangladesh — Complete Guide](https://taeen.com.bd/garment-buying-house-bangladesh) - [AQL Quality Control Guide](https://taeen.com.bd/blog/aql-quality-control-guide) - [Bangladesh Factory Visit Checklist](https://taeen.com.bd/blog/factory-visit-checklist-bangladesh) - [BSCI Audit Process in Bangladesh](https://taeen.com.bd/blog/bsci-audit-process-bangladesh) - [SEDEX SMETA Audit in Bangladesh](https://taeen.com.bd/blog/sedex-smeta-audit-bangladesh) [All articles](https://taeen.com.bd/blog)[Get a sourcing quote](https://taeen.com.bd/contact) ## Related articles [ ![Bangladesh RMG Industry Overview 2026 — Key Facts for Apparel Buyers](https://taeen.com.bd/_next/image?url=%2Fimages%2Fblog%2Fbangladesh-rmg-industry-overview-2026.webp&w=1920&q=75)Market Intelligence August 17, 20269 min read ### Bangladesh RMG Industry Overview 2026 — Key Facts for Apparel Buyers Bangladesh is the world's second-largest apparel exporter — this 2026 overview covers export scale, knitwear strength, green-factory leadership, duty benefits, and key facts buyers need.
