GB/T 19633 vs YY/T 0698: 3 Real Boundaries of Sterile Barrier Systems—Which 3 Documents Should a Printer Request First for Sterile Packaging Orders?
💡 💡 At a Glance
GB/T 19633 and YY/T 0698 are not separate standards; they represent two Chinese registration paths based on ISO 11607: medical device registration versus pharmaceutical packaging material associated review. Three practical boundaries define their use: ① Different applicable stakeholders—the issue is not which standard is stricter, but which registration path the report must enter; an incorrect numbering system can invalidate the entire validation. ② Test method numbers correspond one-to-one—YY/T 0681.1 dye penetration, .2 pressure decay, .3 vacuum decay, .5 internal-pressure peel, and .8 compression—but reports cannot be mixed, and every citation must belong to the numbering set recognized by the customer’s system. ③ Test methods may be shared, but the system cannot be separated: YY/T 0698.1 addresses materials and YY/T 0698.2 addresses formed sterile barrier systems. Sealing performance depends on the material and assembly parameters, so the scope of a printer’s report must be explicit. The first 3 documents a printer should request are the registration path, the material performance specification list, and a clear statement of the printer’s responsibilities.
In April 2026, a factory producing Class I medical devices contacted us to package a batch of sterile devices.
The customer sent us a Packaging Test Report issued by our laboratory, with the test items numbered according to YY/T 0698.1.
Our work was compliant: we performed seal, peel, and dye-penetration testing on every sample using the methods specified in YY/T 0698.1.
On the delivery date, the customer’s quality department returned the report, stating: “We need a report under the GB/T 19633 system. We cannot use this numbering system in our registration system.”
Neither the customer nor we were at fault. The numbering systems are not interchangeable.
After this incident, our factory established an internal rule: when accepting sterile packaging orders, the numbering system must be confirmed before production begins, not after the report has been completed.
The First Boundary: Two Numbering Systems Correspond to the Same International Standards but Apply to Different Stakeholders
First, the relationship needs to be clear. GB/T 19633, Packaging for Terminally Sterilized Medical Devices, adopts ISO 11607-1 and ISO 11607-2 and is a national standard. The YY/T 0698 series, Medical Device Packaging Materials—Sterile Barrier Systems, also adopts ISO 11607 and consists of pharmaceutical industry standards.
The content overlaps substantially: YY/T 0698.1 corresponds to requirements for packaging materials, YY/T 0698.2 to system requirements for formed sterile barrier systems, YY/T 0698.3 to clinical sterile barrier systems, YY/T 0698.4 to process validation for sterile barrier systems, and YY/T 0698.5 to infection control.
However, the applicable stakeholders differ: YY/T 0698 is a pharmaceutical industry standard intended for the pharmaceutical packaging material system, which follows the associated review process of the National Medical Products Administration; GB/T 19633 is a national standard intended for medical device packaging, which follows the medical device registration system.
The practical effect is as follows: a medical device company uses GB/T 19633 for registration, while a pharmaceutical packaging material company uses YY/T 0698 for registration. Although the contents are similar, the report heading, test basis standard numbers, report numbering rules, and the system to which the report is ultimately submitted are all different.
Therefore, the first real boundary is not which standard is stricter, but which registration path the report must enter.
The Second Boundary: Test Item Numbers Correspond One-to-One, but Reports Cannot Be Mixed
This is the point where problems most often occur in practice.
ISO 11607-2 defines a set of standard test methods. In China, the corresponding standards are the YY/T 0681 series, Test Methods for Medical Device Packaging. Examples include:
YY/T 0681.1 for dye-penetration seal testing, YY/T 0681.2 for pressure-decay seal testing, YY/T 0681.3 for vacuum decay testing, YY/T 0681.5 for internal-pressure peel-strength testing, and YY/T 0681.8 for compression seal testing.
Within the GB/T 19633 system, the same tests are generally not cited using YY/T numbers. They may instead be cited as “tested in accordance with ISO 11607-2 / GB/T 19633 Annex X” or may directly reference YY/T 0681.
The problem lies in the citation chain of the report: if a report states on its heading, “Internal-pressure peel testing performed in accordance with YY/T 0681.5; sterile barrier system evaluated in accordance with YY/T 0698.1,” it belongs in the YY system’s documentation file. When the customer needs to submit it under the GB/T 19633 system, the report cannot be filed directly. A qualified institution must reissue it or perform additional accredited testing under the corresponding system.
We encountered this issue when a customer verbally instructed us to follow ISO 11607. We performed the testing under ISO 11607-2 and cited the ISO numbers in the report, but the customer’s registration system required domestic standard numbers and did not accept international standard numbers directly. We learned after the testing was completed that the references had to be changed. Although the methods were identical, the report had to be reissued, wasting both cost and time.
Therefore, the operational key to the second real boundary is: every standard number cited in the report must belong to the set recognized by the customer’s registration system—whether that means YY/T 0681.x and YY/T 0698.x or ISO 11607-1/2 and GB/T 19633. Specify these explicitly and do not leave them ambiguous.
The Third Boundary: Test Methods Can Be Shared, but the “System” Cannot Be Viewed in Isolation
This point is intended for experienced professionals.
ISO 11607-1 and -2 make an important distinction between the material itself, or sterile barrier system, and the formed sterile barrier system. YY/T 0698.1 corresponds to the former, while YY/T 0698.2 corresponds to the latter.
In typical projects, printers generally handle the former by providing sterile barrier materials, including paper-plastic structures, plastic bags, and lid materials. The latter falls within the scope of packaging system suppliers that perform form-fill-seal and thermoforming operations.
However, there is a practical pitfall: seal integrity is not an intrinsic property of the material alone; it results from the combined effects of the material, assembly method, and assembly parameters. Qualified barrier material can still produce an unacceptable seal if the assembly factory uses incorrect temperature, time, or pressure.
Our factory clearly states the printer’s boundary in the customer’s report: the report demonstrates the performance of the sterile barrier material under specified conditions and does not cover subsequent assembly-parameter validation for the formed sterile barrier system. Whether this statement is included can make a material difference in the customer’s registration documentation.
We were once invited to attend a technical meeting because this limitation was missing from the report. The customer’s validation manager asked, “Who is responsible for these sealing parameters?” and nobody responded.
Which 3 Documents Should a Printer Request First When Accepting Sterile Packaging Orders?
Translating these three boundaries into pre-production actions, our factory consistently asks for three items:
First, which registration path the report must enter: the medical device registration system or the pharmaceutical packaging material associated review system. This determines which standard system the report will reference. If the customer cannot clarify this, we do not proceed, because the completed report may be unusable for registration.
Second, the list of specific standard numbers recognized by the customer’s registration system. This includes the test method numbers, whether YY/T 0681.x or the corresponding provisions of ISO 11607-2; the evaluation system numbers, whether YY/T 0698.1/.2/.3 or the corresponding parts of GB/T 19633; and the specific clauses governing the sterile barrier system. We quote only after receiving the numbers, because the numbers determine which tests must be submitted and how many tests are required.
Third, the customer’s existing packaging system validation documentation must specify what the printer is required to undertake. Specifically, this includes the list of material performance specifications, the basis for demonstrating equivalence between trial production and mass production, and confirmation of whether the customer has already completed parameter validation for the formed sterile barrier system. If the customer has not completed formed sterile barrier system validation, the printer must clearly define the scope of its report. This is why the statement described under the third boundary must be included in the report.
One Sentence for Customers
GB/T 19633 and YY/T 0698 are not two separate standards. They are two Chinese registration paths based on the same international standards. Their content can be used for mutual reference, but their reports cannot replace one another.
Our recommendation is to lock down the numbering system once and for all in the contract and technical agreement, including test method numbers, evaluation system numbers, and report heading formats. Once these three elements are clearly specified, the report cannot end up being unusable after completion.

FAQ
Which is stricter, GB/T 19633 or YY/T 0698? Which should a printer follow to be safe?
The two standards overlap substantially and both adopt ISO 11607, with essentially identical technical requirements, so there is no question of which is stricter. The real difference lies in applicable stakeholders and submission paths: GB/T 19633 is a national standard for medical device registration, while YY/T 0698 is a pharmaceutical industry standard for pharmaceutical packaging material associated review. A printer should issue the report using the standard numbers recognized by the customer’s registration system, rather than choosing the supposedly stricter standard. Even a stricter report is unusable if its numbering system does not match the registration system. The safest practical approach is to cover both: perform the tests using YY/T 0681.x or the corresponding methods in ISO 11607-2, and format the report heading according to the customer’s system.
The customer verbally says that following ISO 11607 is sufficient. Can we proceed on that basis?
Technically, yes, because the YY/T 0681 series and ISO 11607-2 correspond to the same test methods. However, domestic registration systems have specific requirements for the standard numbers cited in reports, and international standard numbers cannot directly replace domestic industry standard numbers. Our factory has issued a report using ISO numbers that was later rejected by the customer’s registration system. The testing was not wasted, but the report had to be reissued, resulting in unnecessary costs and delays. Our practice is to confirm the numbering system. If the customer explicitly accepts international numbers, use them. If the customer is uncertain, require them to confirm with their registration consultant and record the requirement in the technical agreement. Spending half an hour on this step can save weeks of work later.
What is the difference between YY/T 0698.1 and YY/T 0698.2? Which one applies to our printing company?
YY/T 0698.1 addresses the material level of a sterile barrier system, such as lid materials, dialysis paper, and plastic bag materials. YY/T 0698.2 addresses formed sterile barrier systems, meaning components that have already been formed and sealed. Printers generally provide the former: paper, film, lid material, and other barrier materials. The customer or form-fill-seal supplier then performs filling and sealing or plastic forming to create the final sterile barrier system. These two levels cannot be separated because seal performance results from the combination of the material, assembly method, and assembly parameters. Qualified material can still produce an unacceptable seal if the assembly temperature or pressure is incorrect. A printer’s report therefore covers only material performance, not final-product assembly validation. This must be stated clearly, or the customer’s validation team will ask who is responsible for the sealing parameters.
The customer wants us to issue a report but says the specific test items have not yet been finalized. Can we start the work first?
It is not recommended. The test items for sterile packaging are determined by the customer’s packaging system validation plan, which is derived from product risk analysis. The required combinations differ substantially according to the sterilization level and intended use of the sterile device. If the printer performs a set of tests based on experience and the customer later finalizes the plan, missing tests must be completed while unnecessary tests represent wasted expenditure. Pricing is also undermined because the number of test items directly determines testing costs, making an accurate quotation impossible without a defined scope. Our standard practice is to obtain three items first: the list of standard numbers recognized by the customer’s registration system, the list of material performance specifications, and confirmation of whether the customer has completed formed sterile barrier system parameter validation. Once these are available, both the test program and quotation can be finalized.
We are only a printer performing printing and die cutting. Why are we being involved in sterile packaging validation?
The printer handles the material level of the sterile barrier. Dialysis paper, printing layers on lid materials, and adhesive layers used in sterile medical device packaging are all part of the sterile barrier system. The material itself must satisfy barrier, seal, and peel performance requirements. The customer generally does not engage a separate testing institution solely for the material. Instead, a qualified third party is usually commissioned to perform the tests, while the printer provides the materials, samples, and process parameters. In another arrangement, the customer conducts validation with the printer’s support by providing trial samples and process records. In both cases, the printer’s responsibility is limited to providing material performance data under specified conditions and records showing that process parameters were followed. The final conclusion on packaging system validation remains the customer’s responsibility.
Can we issue both a GB/T 19633 report and a YY/T 0698 report to reduce the risk?
Technically, this is possible, but it is unnecessary and may create new problems. Testing the same samples twice using the same methods doubles both material costs and time. A more realistic risk is that reports issued by different testing institutions may contain slightly different results, prompting the customer to question why the same samples produced different results in two tests. The better approach is to confirm one path first. If the customer genuinely needs both paths, such as when a medical device subsidiary and a pharmaceutical packaging material subsidiary within the same group both require them, the agreement should specify that the reports cover the same samples, use the same methods, and are issued by the same institution, with the underlying records retained so that the results are traceable and mutually verifiable.
