Quick answer. A pre-shipment inspection checks finished, packed goods at the factory before you pay the balance and before anything leaves for Amazon. An inspector pulls a random sample from the lot and checks quantity, labels and barcodes, packaging, function, workmanship and safety marks against a written checklist and an approved golden sample. AQL sampling sets how many units to open and how many defects you accept before the lot fails. The goal is to catch what Amazon’s rules would punish later, such as items that miss the New condition standard, packaging a fulfillment center can refuse, and missing safety certificates. Keep every report, photo and certificate. Those records cut quality complaints and become the evidence in a plan of action if Amazon ever asks what went wrong.

Most sellers who source from overseas factories, often found on a business to business sourcing marketplace, see their product for the first time when a customer opens it. By then the supplier is paid, the units sit in a fulfillment center, and the first return says the hinge snaps or the charger is missing. A pattern of those turns into a listing removal or a policy warning about a defect the seller never saw.

A pre-shipment inspection moves that first look to the factory, where a bad lot can still be reworked or refused at the supplier’s cost.

This article is educational information, not legal or regulatory advice. Product safety obligations depend on the product, its users and its classification, so confirm your specific requirements with the regulator or a qualified professional.

Why the inspection has to happen before the goods ship

Once inventory leaves the factory, every fix gets slower and more expensive. A lot rejected at the factory can be reworked while the line is still set up. The same lot found at a fulfillment center has to be removed or disposed of, and customers who received bad units have already complained.

What Amazon does with problem inventory

Amazon’s product packaging requirements say inventory arriving with non-compliant, unsafe packaging may be refused or disposed of at your expense, with no reimbursement. Amazon may also refuse, return or repackage products with inadequate packaging or labeling, and may add product-specific requirements because of damages and damage-related returns. Condition and safety also count toward Account Health, which names both the product condition guidelines and product safety and compliance among its policies.

What the factory can still fix

Until you pay the balance, the supplier has a reason to fix the lot. After a failed inspection, you can ask it to sort, rework, re-label or re-pack, then re-inspect. Amazon’s supplier guidance recommends contracts that make the supplier responsible for inventory that receives legitimate complaints about quality or authenticity. An inspection gives that clause teeth, because it records the lot as the supplier handed it over.

The further a defect travels, the fewer options you have to fix it quietly and the more it costs.

What a pre-shipment inspection checks

A useful inspection is a written checklist, agreed with the supplier before production ends, that the inspector works through on a random sample. It covers six areas, each tied to something Amazon or a regulator checks later.

Quantity and assortment

The inspector counts cartons against your purchase order, then opens cartons to confirm units per carton and the assortment inside. Amazon’s packaging requirements say each FNSKU must correspond to one unique product, so each size or color needs its own FNSKU, and so does each condition. A carton labeled “blue, medium” holding “blue, large” units will ship the wrong item to a customer. For case packs, Amazon says every box must hold one SKU in one condition, packaged together by the manufacturer, with equal quantities in each box and no more than 150 units per case. The fulfillment center scans one unit per case, so a short or mixed case is never caught at receiving.

Labels and barcodes

Amazon’s FBA barcode requirements cover manufacturer barcodes such as UPC, EAN, JAN and ISBN, and Amazon barcodes, the FNSKU labels that start with an X. The requirements changed as of March 31, 2026. Brand owners can keep using manufacturer barcodes without stickers, while resellers must use Amazon barcodes even when a manufacturer barcode exists. Check the current page and your barcode setting before briefing the factory. The inspector should scan sampled labels, not only look at them, and confirm each label sits on a flat exterior surface, not a corner or curve, with human-readable numbers. Old barcodes on outer shipping boxes must be covered or made unscannable.

Packaging and prep

Many factory lots fail Amazon’s rules without anyone noticing. Put the Amazon requirements that apply to your product on the checklist.

Boxed units six-sided and firm under pressure. Products over 10 lb or sharp products in double-wall corrugated boxes.
A suffocation warning on poly bags with a 5-inch or larger opening, measured flat.
Sets labeled as sets, for example “Sold as set.”
Over-boxing for fragile items that failed a 3-foot drop test after bubble wrap, among other categories Amazon lists.
Expiration dates as MM-DD-YYYY or MM-YYYY on units and on the outer box in 36-point or larger font. Amazon says lot numbers alone are insufficient.
No pre-priced labels, price tags, marketing inserts or theft-prevention devices.

Function, workmanship and contents

The inspector runs each sampled unit through a function test written for your product, checks dimensions, compares the finish to the golden sample, and confirms every accessory, part and manual the listing promises is in the box. Tie these tests to Amazon’s condition guidelines. Amazon defines New as a brand-new item with any original manufacturer’s warranty still applying. It lists as unacceptable items that are not clean, damaged in a way that makes them difficult to use, missing necessary accompanying material or parts, or in need of repair. A unit that fails those tests at the factory would fail Amazon’s New standard.

Safety marks and certificates

Last, the inspector confirms that required warnings and markings are physically on the product and packaging, and that your certificate describes this exact product. The CPSC section below explains what to match.

AQL sampling in plain terms

Nobody opens every unit in a lot of several thousand. Inspectors use acceptance sampling, usually called AQL, for acceptance quality limit. You agree in advance how many units to pull at random, how serious each type of defect is, and how many of each type you tolerate before the whole lot fails.

The three decisions you make first

Sample size. In published sampling tables, the number of units to inspect depends on lot size and the inspection level you choose. A stricter level opens more units. Have the inspector name the table and level in the report so anyone can see later how the sample was drawn.

Defect classes. Critical defects could make the product unsafe or non-compliant. Major defects make it fail its purpose or likely to be returned. Minor defects are cosmetic. Agree in writing which observed problems belong in which class.

Acceptance limits. These turn the defect count into pass or fail. Many buyers accept zero critical defects and set looser limits for major and minor ones. No Amazon or government number tells you what to use. The right limits depend on your product, your price and the cost of a defect reaching a customer.

A worked example with hypothetical numbers

A seller orders 3,000 insulated bottles. The plan pulls 125 bottles at random from cartons across the lot. A leaking lid or missing seal ring is major, a scuff on the base is minor, and a sharp burr on the rim is critical. The agreed limits are zero critical, up to 3 major and up to 7 minor. The inspector finds no critical defects, 5 major (four leaking lids, one missing ring) and 4 minor. The lot fails on major defects. Because four majors share one cause, the seller asks the factory to find it, re-test every lid, replace failures and book a re-inspection. These figures are illustrative only.

A passed sample means the lot is likely within your limits, not that every unit is perfect. Sampling cannot catch a failure the checklist never tests. When returns reveal a new failure mode, add a test for it to the next lot.

Defect class	What it means	Typical examples	Usual tolerance approach
Critical	Could make the product unsafe or non-compliant	Exposed sharp edge, missing required warning, wrong or absent safety marking	Often zero. One found fails the lot
Major	Product fails its purpose or is likely to be returned	Does not power on, leaks, missing accessory, wrong size in carton	Low limit agreed per product
Minor	Cosmetic, unlikely to cause a return alone	Small scuff on a hidden surface, slight print offset	Higher limit agreed per product

Golden samples. The reference both sides sign

A checklist says what to check. A golden sample shows what right looks like. It is a finished unit you approve before mass production, and it becomes the physical reference for color, finish, fit, printing, packaging and contents.

How to set one up

Approve the pre-production sample only after using it the way a customer will. Keep two identical approved units, one sealed at the factory and one with you. Mark each with the date, product name and purchase order, have both sides sign across the closure, and photograph both. When a report says “color differs from golden sample,” everyone compares against the same object.

Why it matters later

Factories swap materials or components to save cost, and each change looks small. Over several orders the product can drift away from your listing. A sealed, dated reference makes drift visible and shows when the product changed. If you change the product on purpose, approve a new golden sample and update the listing, so listing, sample and lot always describe the same item.

Safety marks and CPSC certificates

For many consumer products sold in the United States, safety compliance is a legal requirement. The inspection is your chance to confirm the paperwork matches the physical product.

General Certificate of Conformity

CPSC explains that domestic manufacturers and importers of certain general-use products must certify, in a written General Certificate of Conformity based on testing or a reasonable testing program, that the products comply with applicable safety rules. CPSC lists seven required elements.

Identification of the product, detailed enough to match the certificate to that product only.
A citation to each CPSC safety rule the product is certified to.
Name, full mailing address and telephone number of the certifying importer or domestic manufacturer.
Contact information for the person maintaining test records.
Date and place of manufacture.
Dates and places of testing.
Any third-party laboratory that conducted the testing.

CPSC says no specific template is required as long as these elements are present, and the certificate must be in English.

Children’s Product Certificate

CPSC defines a children’s product as one designed or intended primarily for children 12 years of age or younger. These products require third-party testing, and the Children’s Product Certificate must be based on results from a CPSC-accepted third-party laboratory named on the certificate. Both CPSC pages also note that starting July 8, 2026, importers of most regulated consumer products must electronically file certificates with U.S. Customs and Border Protection. If you are the importer of record, check CPSC’s eFiling guidance.

Matching the certificate to the lot

The inspector compares the certificate with the product on the table, checking model, description, place of manufacture and rules cited, then confirms required warnings and markings are printed on the product or packaging. A certificate naming a different model or factory, or a test older than a material change, is a gap to close at the factory. Never alter or back-date a certificate or test report. If the document does not match, have the correct product tested, obtain a genuine certificate, or stop selling until you can.

When inspection finds a real hazard

CPSC explains that manufacturers, importers, distributors and retailers must report when they obtain information reasonably suggesting a product has a defect that could create a substantial risk of injury, creates an unreasonable risk of serious injury or death, or fails an applicable safety rule. CPSC says a company must report within 24 hours of obtaining reportable information, and its staff advise “when in doubt, report.” This is a legal question, so get qualified advice promptly.

Factory checks before production even starts

An inspection at the end catches problems. A factory check at the start prevents some of them. Amazon’s supplier guidance recommends understanding the supplier’s quality control and inventory processes, specifying the quality standards and certifications it must meet, confirming whether it can provide a Certificate of Insurance, and considering site visits or third-party audits. It also recommends monitoring supplier performance and lining up alternatives if standards slip, and notes that the guidance is general information, not legal advice.

On a visit, look for quality built into the process. Incoming material checks, in-line production records, a separate area for rejected units, and staff who can show you the last failed batch and what happened to it. Then write the checklist, sampling plan, golden sample reference, applicable Amazon prep rules, required certificates and re-inspection costs into the purchase order. A failed inspection then becomes a contract matter, not a negotiation.

How inspection records reduce quality complaints

Over several orders, inspection records show where your product fails and whether fixes work.

Connect returns to lots and find the source

When return reasons cluster around “defective” or “missing parts,” find which lot those units came from and compare the comments with that lot’s report. Condition complaints usually come from one of three places. Units defective when they left the supplier (sourcing), units damaged or mixed up in storage, prep or shipping (handling), or units exactly as made but described differently in the listing (listing). The inspection record separates sourcing from the other two fastest, because it shows the lot as it left the factory.

Watch for drift toward authenticity concerns

To a customer, a run of “not as described” complaints can look like a question about whether the product is genuine. Amazon’s condition guidelines list copies, counterfeits, replicas and imitations as unacceptable. If your product changes quietly between lots, customers comparing it with an earlier unit may report it as fake. Golden samples and consistent inspection stop that drift.

Using inspection records as evidence in a plan of action

Amazon’s appeal page says that to appeal an account deactivation, you go to Account Health, click Reactivate your account and follow the instructions, which may include a questionnaire, acknowledging a violation, a quiz or supporting documents. For a listing removal, Amazon says to check the Product Policy Compliance tab, then Manage Inventory for inactive listings, and to review Performance Notifications. Amazon says to expect a reply to an account appeal within two days.

What the plan of action must prove

It answers three questions with evidence. Root cause. Which units failed, where the defect came from, and why your process let it through. Corrective actions already taken. What you did about affected inventory and buyers, with dates. Preventive controls. What changed, who owns it, and from when. The lot report and photos show whether the defect existed at the factory. Removal orders, rework correspondence, refunds and the re-inspection report show corrective action. The revised checklist, new test, tighter limit and named approver show the control is real.

Here is a hypothetical root cause built on those records. “Leaking lid complaints on this ASIN trace to lot 14. That lot’s checklist had no seal test, so the defect was not sampled. We removed the remaining units, refunded affected buyers, added a seal test with zero tolerance, re-inspected the corrected lot, and assigned our operations manager to approve every future lot.” A document backs every claim.

Safety cases need specific documents

For an ASIN suppressed over safety, Amazon’s policy says sellers must resolve and document all safety issues, confirm removal of impacted inventory from fulfillment centers, and upload a Letter of Compliance to a Seller Central case. The letter must be a PDF on the manufacturer’s letterhead, signed by a relevant stakeholder, with the recall reason, affected ASINs and titles, confirmation of future compliance, and applicable safety certifications and test reports. Not all products may be eligible for reinstatement. Sellers must also initiate removal orders within 30 days and maintain complete records for regulatory review.

When the records do not exist

Never create a report after the fact. Say honestly that inspection was missing, show what you have done since, such as inspecting remaining stock or commissioning a new lab test, and make the new program your preventive control.

A repeatable routine for every order

Sellers who rarely face quality complaints run the same short routine on every purchase order and treat each result as data.

Before ordering. Vet or re-check the supplier against Amazon’s due diligence outline, confirm the certificate you need, and search CPSC recalls and SaferProducts.gov for your product type.
With the purchase order. Send the checklist, sampling plan and limits, Amazon packaging and barcode requirements, and the golden sample reference.
Before balance payment. Run the pre-shipment inspection on the packed lot, decide pass or fail on the agreed limits, and re-inspect after any rework.
After the goods go live. Compare return reasons and Account Health notices with the lot’s inspection record each month.
Every few orders. Update the checklist with any new failure, re-approve the golden sample if the product changed, and review whether the supplier still meets your standard.

Frequently Asked Questions

What is a pre-shipment inspection?

A check of finished, mostly packed goods at the factory before shipment and final payment, using a random sample and a written checklist.

Does Amazon require a pre-shipment inspection?

Amazon’s help pages do not require a specific inspection. Its packaging, barcode, condition and safety rules still apply to everything you send, and its supplier guidance suggests reviewing supplier quality control and considering third-party audits.

What does AQL mean?

Acceptance quality limit. It is an agreed sample size, a set of defect classes, and the number of defects in each class you accept before a lot fails.

What AQL level should I use?

No Amazon or government number applies. Many buyers accept zero critical defects and set limits for major and minor defects by product and price.

What is a golden sample?

An approved unit, sealed and dated by you and the factory, used as the physical reference for every later lot.

Which certificate does my product need?

CPSC says certain general-use products need a General Certificate of Conformity, and children’s products need a Children’s Product Certificate based on testing by a CPSC-accepted third-party laboratory.

Can inspection reports help me get reinstated?

Genuine, dated reports can support the root cause, corrective actions and preventive controls in a plan of action. They do not guarantee an outcome.
