Third-Party Inspection and Testing Costs in Packaging Procurement: Three Practical Boundaries—Who Commissions, Who Pays, and Who Bears the Consequences of Nonconformance—The First Three Questions to Ask When a Printer Receives a Third-Party Inspection Inquiry
💡 💡 At a Glance
Third-party inspection and testing in packaging procurement involve three essential boundaries. First, inspection and testing are different commissions with different reports and effects. Inspection involves on-site witnessing and sampling under an agreed standard, checking quantity, dimensions, appearance, workmanship, packaging method, and shipping marks against the approved sample and specifications. Its conclusion is conforming, nonconforming, released, or temporarily accepted. It does not establish regulatory compliance or fitness for sale, and inspection agencies do not issue laboratory test-data reports. Testing requires samples to be sent to a laboratory, where standard methods are used to produce a data report with a report number and CMA/CNAS marks. Timing must be planned in advance because testing may take several days to two weeks. The approved sample and specifications must be locked before inspection. Second, costs fall into three categories. Inspection fees are generally paid by the commissioning party. Testing fees may follow the owner-pays principle, be allocated into the unit price by shipment batch, or be borne by the printer. Retesting and third-party adjudication fees are usually paid by the responsible party when the initial test fails, based on written standards and limits agreed in advance. Third, a passed inspection does not mean final order acceptance, and a third-party report does not release the printer from responsibility. The contract should state whether the inspection report is an input into or a substitute for acceptance and define the customer’s acceptance deadline and deemed-acceptance rule. Testing agencies are responsible for testing methods and scientific data, not the product’s actual compliance or losses. Third-party inspection covers only the sampled units under an AQL plan, not every unit. Hold items also require advance rules covering decision authority, deadlines, rework costs, and delivery schedules. The first three questions are: Who is commissioning the work, and is it inspection or testing? Which items will be tested, by which methods, and with what limits? What retesting, adjudication, Hold, rework, and acceptance mechanisms apply if nonconformance occurs?
In July 2026, a health-products customer asked to send a third-party inspection team for the first time.
“We’re going to appoint a third-party agency to inspect the goods.”
We asked, “What needs to be inspected?”
The customer replied, “Just check whether it was made correctly.”
We asked again, “Are you checking appearance, dimensions, and quantity, or sending the samples to a laboratory for testing?”
The customer said, “…I’m not entirely sure either. Procurement decided it.”
We said, “Then let’s separate these two services first, because their costs and responsibilities are entirely different.”
This issue is particularly easy to confuse in packaging procurement. Inspection is process witnessing, while testing is performance determination. The former determines whether a production lot matches the approved sample and confirmed specifications; the latter involves laboratory testing of samples and the issuance of a data report. The commissioning party, cost, legal effect of the report, and consequences of nonconformance differ in each case.
This article explains three practical boundaries and ends with the first three questions a printer should ask when receiving this type of inquiry.
Boundary One: Inspection and Testing Involve Two Different Commissions, Two Different Reports, and Two Different Effects
First, inspection. A third-party inspection agency performs on-site witnessing and sampling: it draws a number of units from the lot according to an agreed sampling standard, such as an AQL sampling plan, and then checks whether quantity, dimensions, appearance, workmanship, packaging method, and shipping-mark information conform to the approved sample and specifications. It then issues an inspection report whose conclusion is generally “conforming,” “nonconforming,” “released,” or “temporarily accepted.”
The effect of an inspection report has a clear boundary: it witnesses the judgment that “this lot conforms to the specifications.” It is not a conclusion that “this lot complies with regulations” or “this lot is fit for sale.” Inspection agencies do not hold laboratory qualifications and do not issue compliance reports containing test data.
The customer asked, “Why not ask the inspection agency to measure migration levels while they’re there?”
We replied, “The inspection agency is not qualified for that test, and the customer’s own procurement and legal teams will not recognize the resulting report. To obtain test data, you must engage a qualified testing agency to perform laboratory testing and issue a report with a report number and CMA/CNAS marks. These are two separate workstreams and must be arranged separately.”
Now consider testing. A testing agency performs sampling and laboratory submission, testing according to standard methods, and preparation of a data report. Examples include migration and heavy-metal testing for food-contact materials; compression, drop, and stacking-strength testing for corrugated boxes; and color-difference, registration, and peel-strength testing for printed products.
The customer asked, “Does a test report mean that acceptance has been passed?”
We replied, “No. This is the point that most needs to be clarified, and we address it separately under the third boundary below.”
Another issue that is often overlooked is timing: inspection is conducted on the production site, while testing requires the samples to be sent to a laboratory and generally takes several days to two weeks. If the customer requires payment on the day the inspection report is issued, the test report will often not yet be available. This timing difference should be addressed during scheduling rather than raised on the day of inspection.
Finally, one practical detail is essential: the approved sample and specifications must be locked before the inspection agency arrives. Many failed inspections are not caused by production errors at the printer. Instead, multiple versions of the approved sample may exist because the customer changed the design internally without synchronizing it, leaving each party holding a different version it considers correct. Responsibility for this lies in the approval process rather than production, although the problem surfaces at the inspection site.
Boundary Two: Cost Allocation—Inspection Fees, Testing Fees, and Retesting Fees Are Three Separate Costs
These three costs are often combined into a single “testing fee,” leaving no party willing to settle it.
Cost One: Inspection fees. Industry practice is for the commissioning party to bear these costs. If the customer commissions the inspection, the customer pays; if a brand owner commissions it, the brand owner bears the cost. The printer generally does not pay inspection fees unless the contract provides otherwise. This point is rarely disputed, so it simply needs to be stated clearly.
Cost Two: Testing fees. This is where contractual arrangements diverge. Three formulations are common. First, “the owner of the product pays,” meaning the customer pays for the customer’s products. Second, the testing fee is “allocated into the unit price by shipment batch,” allowing the printer to spread the cost across the unit price and earn slightly less on each SKU, while the customer bears the total cost. Third, “the printer bears the cost,” which is more common when the printer is the responsible party and the customer specifies the testing agency.
The customer asked, “Approximately how much will the testing cost?”
We replied, “It depends on how many items need to be tested. Migration and heavy-metal testing for food-contact materials is a common combination. A complete set of transportation tests for corrugated boxes—compression, drop, vibration, and stacking—is another. Quality testing for printed products is yet another. A single test and a multi-test package are not priced alike. Rather than asking about unit prices, we recommend first confirming which tests the order actually requires. Many customers arrange every test that is technically available, with roughly half representing routine requirements and the rest added through internal standards. Removing unnecessary tests can make a substantial difference in cost.”
Cost Three: Retesting fees and third-party adjudication testing fees. This is a major source of disputes. If the initial test fails, retesting follows. Who pays for it? A common industry practice is: the commissioning party pays for the initial test; if the initial test is nonconforming, the responsible party bears the retesting cost. Responsibility is determined according to the acceptance criteria agreed in the contract—not according to whether the printer declares the goods conforming or the customer declares them nonconforming, but according to written decision rules confirmed in advance by both parties.
One matter must be settled in advance: the criteria for determining “nonconformance.” If the customer merely states “according to our standards,” inspection and testing will have no basis for adjudication. Appropriate language should cite specific standard numbers and limits, such as: “Total migration shall be tested according to GB 31604.1 and shall not exceed 10 mg/dm².” Without this provision, later retesting, adjudication, and disputes will have no clear reference point.
The customer said, “Our standards are detailed internal documents.”
We replied, “Then extract the key items and include them in the contract or order confirmation: which items will be tested, which methods will be used, what the limits are, who will commission the work, who will pay, and how nonconformance will be handled. The remaining details can remain in an appendix, but the basis for decision-making must be traceable in the main document.”
Boundary Three: A Passed Inspection Does Not Equal Final Acceptance, and a Third-Party Report Does Not Release the Printer from Responsibility
This is the most important of the three boundaries because it concerns responsibility.
Level One: A passed inspection does not mean the order has been accepted. When an inspection agency concludes “conforming,” it means that the lot conforms to the inspection criteria, generally the approved sample and specifications. Order acceptance, however, is a commercial action involving the customer’s receipt and confirmation that the order is complete. The two actions occur at different times and produce different consequences. In practice, an awkward situation may arise in which the inspection report states “conforming,” but the customer still refuses to accept the goods on the grounds that “inspection is the third party’s responsibility, and we still have an internal acceptance process.”
The contract should therefore clarify the relationship between the two actions: whether the inspection report is an input into the acceptance process or a substitute for it. If it substitutes for internal acceptance, the conditions and effect of substitution should be specified. If it serves as an input, the customer’s internal acceptance deadline should be stated—for example, objections must be raised within seven business days after receipt, after which the goods are deemed accepted.
Level Two: A third-party report does not release the printer from responsibility. A third-party test report provides a technical basis for resolving disputes; it does not transfer responsibility to the testing agency. The testing agency is responsible for the scientific validity of its testing methods and data, but not for the actual compliance of the tested products or for resulting losses. If the investigation establishes that the ink itself was defective, responsibility lies with the ink supplier. If the printer failed to control the printing process—for example, through inadequate curing—responsibility lies with the printer, regardless of the testing agency’s involvement.
The customer asked, “Then what is the point of paying for third-party testing?”
We replied, “Its purpose is to turn a dispute in which each side simply asserts its own position into one decided according to report data, and to provide both parties with a traceable reference point if a genuine problem occurs. The customer’s own test reports serve the same purpose. The difference is that a third party offers greater neutrality and is therefore more readily accepted when the customer and printer do not trust one another.”
Level Three: The limits of witnessing. The printer should proactively define one point: third-party inspection witnesses the units selected in the sample. A sampling plan, such as AQL, itself recognizes that inspecting every unit is impossible. The conclusions in an inspection report therefore describe the condition of the lot on the basis of sampling and do not constitute an absolute guarantee of zero defects. This does not mean the printer may relax quality control. Rather, both parties need to understand what the report can and cannot prove.
Another scenario frequently causes disputes: on the day of inspection, a third-party agency identifies an issue that does not constitute nonconformance but is classified as a “Hold”, such as crooked labels, packaging methods that do not meet the customer’s requirements, or one discrepancy in shipping-mark information. These issues are normally listed separately in the inspection report as Holds and require a written customer decision to accept them or require rework. Contracts often leave the rework schedule and cost allocation unresolved. This must be addressed before cooperation begins: who decides Hold items, within what period, and who pays for rework.
The First Three Questions to Ask When a Customer Requests a Third-Party Inspection
Question One: Who is commissioning the work, and is it inspection or testing? Is the customer appointing the agency directly, engaging an agency through the customer, or complying with a brand owner’s designation? Inspection—on-site witnessing, sample checks, and conformity determination—must be distinguished from testing—laboratory data reports. Their scheduling, costs, and report effects differ. Once this is clear, the remaining arrangements follow logically.
Question Two: Which specific items will be tested, using which methods, and subject to what limits? The inquiry must be specific enough to cite standard numbers, such as “Total migration shall be tested according to GB 31604.1, with a limit of ≤10 mg/dm².” Phrases such as “according to our standards” are insufficient. These details also provide the basis for retesting and adjudication.
Question Three: What mechanism will apply in the event of nonconformance? Who pays for retesting; how third-party adjudication testing will be commissioned and decided; who will decide Hold items and within what period; how rework scheduling and costs will be allocated; and the deadline for the customer’s internal acceptance, including any deemed-acceptance rule for missed deadlines.
Once these three questions are clear, the arrangement of an inspection and testing order is unlikely to encounter major problems.
One Sentence for Customers
Regarding third-party inspection, the most important thing we want to tell customers is: “Please write the two statements ‘conforms to the approved sample’ and ‘conforms to the standards’ separately.”
The customer asked, “Is there really a difference?”
We replied, “There is a major difference. The approved sample is the single item we agreed on together, while standards are regulations and national standards. If the approved sample changes, it must be reconfirmed; standards cannot be changed. Many contracts currently combine both concepts in a single sentence, and once a dispute arises, each side simply asserts a different position.”

FAQ
If the third-party inspection report states “conforming,” have we completed delivery?
Not necessarily. The inspection report concludes that the lot conforms to the inspection criteria, generally the approved sample and specifications. This is a technical determination, whereas order acceptance is a commercial action involving the customer’s receipt and confirmation that the order is complete. The two occur at different times and have different consequences. Even after a passed inspection, the customer may defer confirmation because its internal acceptance process remains incomplete. The contract should therefore state whether the inspection report is an input into or a substitute for acceptance. If it is an input, include the customer’s internal acceptance deadline—for example, objections within seven business days after receipt, after which the goods are deemed accepted—to prevent indefinite non-acceptance from becoming the default.
Who ultimately pays the testing fees?
Break the costs into three separate items rather than treating them as one. First, inspection fees are conventionally borne by the commissioning party, and the printer generally does not pay unless the contract states otherwise. Second, testing fees commonly follow one of three arrangements: the owner of the product pays; the cost is allocated into the unit price by shipment batch, with the printer spreading the cost but the customer bearing the total; or the printer bears the cost, which is more common when the printer is the responsible party and the customer specifies the agency. Third, retesting and third-party adjudication fees are a major source of disputes. Common practice is for the commissioning party to pay for the initial test and for the responsible party to pay for retesting if the initial test fails. Responsibility is determined through written acceptance criteria agreed in advance, including specific standard numbers and limits—for example, “Total migration shall be tested according to GB 31604.1 and shall not exceed 10 mg/dm².”
If a third-party laboratory finds the goods nonconforming, is responsibility the printer’s or the laboratory’s?
The responsibility lies with the printer or its supply chain, not the laboratory. The testing agency is responsible for the compliance of its testing methods and the scientific validity of its data, but not for the product’s actual compliance in use or for resulting losses. If the ink is at fault, responsibility lies with the ink supplier. If the printing process was improperly controlled—for example, insufficient UV curing caused unreacted residues—the printer is responsible. A third-party report provides a technical basis for resolving disputes by replacing competing assertions with decisions based on data; it does not transfer responsibility.
How should an “Hold” listed in an inspection report be handled?
A Hold is listed separately in an inspection report and generally does not constitute formal nonconformance, but it requires a written customer decision. Examples include crooked labels, packaging methods that do not meet requirements, or one discrepancy in shipping-mark information. The customer must decide in writing within the agreed period whether to accept the issue or require rework, yet many contracts leave the rework schedule and cost allocation blank. These matters must be addressed before cooperation begins: who decides Hold items, within what period, who bears the rework cost, and whether rework affects the delivery deadline. Otherwise, the most common outcome is a Hold raised on the inspection day followed by weeks of dispute over rework costs and delay responsibility.
If the inspection agency samples only part of the lot, is it responsible for defects missed by the sampling?
No. Sampling recognizes that inspection of every unit is impossible. The purpose of an AQL sampling plan is to exchange an acceptable level of risk for lower inspection costs. Third-party inspection witnesses the units selected in the sample, so its conclusion describes the condition of the lot on the basis of sampling rather than making an absolute zero-defect guarantee. This does not permit the printer to relax quality control. On the contrary, if a problem is detected through sampling, it often indicates a systemic deviation that should have been caught by the printer’s own initial and in-process inspections. The contract should treat third-party inspection as one piece of acceptance evidence rather than a transfer of quality responsibility.
