Direct answer: An ESD packaging specification should identify the protected item and handling route, define the required protective functions, name the governing standard and test method, describe the complete box-and-divider configuration, and set conditioning, acceptance, traceability and sample-approval requirements. Цвет, a material label or one favorable reading does not prove compliance.
On 30 August 2026, CCTV reported—citing customs data—that China’s integrated-circuit exports reached US$216 billion in the first seven months of 2026, up 99.5% year over year and already above the US$201.9 billion reported for all of 2025. The same report said first-half PCB exports reached US$16.12 billion, up 34%. It also described the growth reaching semiconductor packaging equipment, PCB manufacturing and logistics. Read the CCTV report.
That market growth does not change ESD physics or the applicable standards. It does make a repeatable procurement specification more valuable when more parts, suppliers, shifts and returnable containers enter the flow. The checklist below is designed to remain useful after the news cycle moves on.
For a term-by-term material comparison, use Jinmai’s anti-static vs conductive PP hollow-sheet guide. This article starts one step later: turning an approved ESD requirement into a request for quotation (запрос цен), test plan and production-release record.
Key takeaways
- Start with the device, its route and the required protective functions—not a color or material label.
- Low-charging behavior, resistance-related properties and discharge shielding answer different risks.
- State whether acceptance applies to raw sheet, converted components, the assembled box or the loaded packaging system.
- Treat the box body, knife-card dividers, контактные площадки, lid, labels and hardware as defined parts of one configuration.
- A test requirement is incomplete without the method and revision, sample condition, measurement path, test points, conditioning and acceptance rule.
- Approve structure, use performance and ESD evidence as separate decisions, then link the approved sample to a controlled production revision.
What Should an ESD Packaging Specification Include?
An RFQ is easier for suppliers to price—and for buyers to audit—when it follows the product’s actual handling route.
On a small screen, swipe the table sideways to view all columns.
| Specification field | What the buyer should write | Why it belongs in the RFQ |
|---|---|---|
| Protected item | Part number or family, dimensions, weight, exposed terminals, sensitive surfaces and available sensitivity or customer information | Identifies what can be damaged and what may contact the package |
| Handling route | Loading, хранилище, line feeding, work in process, транспорт, customer receipt, return and cleaning; identify stages inside and outside an ESD protected area (EPA) | The required protective function can change along the route |
| Required functions | Low charging, an agreed resistance-related classification, discharge shielding, physical separation or a documented combination | Replaces the vague phrase “ESD safe” with an engineering requirement |
| Governing documents | Standard, customer specification, drawing or internal procedure, including revision | Establishes the controlled basis for design and acceptance |
| Package configuration | Box dimensions, lid, knife-card or grid layout, контактные площадки, contact surfaces, access, grounding features if applicable, labels and hardware | Defines the item that will actually be handled and approved |
| Test and conditioning | Property, method, test object, electrodes or measurement path, locations, environmental conditioning, sample quantity and acceptance rule | Makes supplier and buyer results comparable |
| Evidence and traceability | Report fields, sample ID, drawing revision, material or lot reference, retained records and change-notification requirements | Connects an approved result to the delivered product |
| Release process | Sample stages, approval owner, first-production checks and handling of deviations | Prevents an informal “sample OK” from becoming an unlimited approval |
Standards note: IEC 61340-5-3:2022 и ANSI/ESD S541-2026 define packaging properties and reference test methods for protecting ESD-sensitive items. The project specification should identify the applicable document and revision, then add the buyer’s device, handling route, test conditions and acceptance criteria. The licensed standard and customer requirements govern.
If any field is unknown, write “buyer ESD program owner to confirm” instead of allowing a supplier to fill the gap silently.
Match each risk to a protective function
“Anti-static,” “static-dissipative,” “conductive” and “shielding” are often used as if they were grades on a single scale. They are not interchangeable purchasing instructions.
On a small screen, swipe the table sideways to view all columns.
| Risk or handling condition | Function to evaluate | Question for the specification owner |
|---|---|---|
| Charge generated when the product, operator and packaging contact and separate | Low-charging behavior of relevant surfaces | Which surfaces touch the device, and how will low-charging performance be evaluated? |
| Charge must move through a controlled package or grounded handling system | The applicable resistance-related property and connection path | Which property, method and system arrangement does the ESD control plan require? |
| The package moves outside a controlled ESD protected area | Discharge shielding, where required, or an additional qualified packaging layer | What protection is required before the package leaves the EPA? |
| Parts can collide, scrape, bend or mix during movement | Cell geometry, clearance, orientation, lid and mechanical structure | What movement and contact are acceptable during the complete route? |
The EOS/ESD Association’s ESD control overview distinguishes packaging used inside an EPA from packaging used outside it. A reusable divider box that supports controlled internal handling should not automatically be described as providing every protective function needed for uncontrolled transport.
Three shortcuts that do not prove compliance
- Black color: Black can be used for identification or can result from a formulation, but appearance is not an electrical test.
- A material name: “PP,” “anti-static PP,” “conductive PP” or a supplier grade name does not, by itself, state the required package function, method or acceptance criteria.
- One test result: A single reading cannot establish compliance if the test object, parameter, method, conditioning, locations, sample quantity and pass rule are undefined.
Resistance is one property. It should not be used alone to infer low-charging behavior, discharge shielding or the performance of a complete package.
Specify the finished box and knife-card dividers
For PCB assemblies, chips in secondary carriers, connectors, sensors and other precision parts, the packaging system may include a box body, interlocking knife-card dividers, контактные площадки, a lid, edge protection, ручки, этикетки, print and fastening hardware. Each component can have a different contact role.
If the packaging structure is not yet defined, start with Jinmai’s ESD corrugated plastic box selection guide. Use this specification page once the required functions and package configuration are ready to become an RFQ, test plan and approval record.
State the acceptance unit instead of assuming that a flat sheet coupon represents everything made from it:
On a small screen, swipe the table sideways to view all columns.
| Possible test or approval unit | What it can show | What it cannot automatically prove |
|---|---|---|
| Raw PP hollow-sheet coupon | A result for the identified sheet sample under the stated method and conditions | Finished-box performance, every converted face or later production lots |
| Cut, creased or welded component | The property of a defined converted part or area | The behavior of the full assembled and loaded package |
| Assembled box and divider set | Results at specified locations on the approved configuration | Product fit, operator handling or protection after an undefined change |
| Loaded pack-out | Clearance, orientation, access, movement and complete-route handling | Unmeasured ESD properties or unrelated future configurations |
Define which box and divider surfaces contact the product. Include cell length, width and depth, loading direction, finger clearance, prohibited contact areas, quantity per cell and total load. If dividers are removable, identify the correct installation orientation and any part number or marking needed to prevent mix-ups.
The divider does not automatically need the same material description as the outer box. It does need a written requirement that matches its actual role. Conversely, an outer box result should not be used to approve an untested direct-contact divider when that divider is part of the specified protective system.
What Test Details Should an ESD Packaging Specification Include?
“Test the surface resistance” is not a complete instruction. Before comparing quotations or reports, write down:
- The property being evaluated and the acceptance parameter.
- The standard, customer method or internal procedure, including revision.
- The test object: sheet coupon, cut part, divider, assembled empty box or loaded configuration.
- The measurement path and direction, and the electrode or apparatus required by the method.
- Test voltage or other instrument settings when required by the governing method.
- Temperature, relative humidity and conditioning period specified by the method or ESD control program.
- Whether the sample is tested as received, after cleaning, after use or after another defined exposure.
- Measurement locations, including contact surfaces or converted areas where relevant.
- Sample quantity, allowed failures, retest rule and acceptance authority.
- Report fields, including individual results rather than only an average or pass statement.
Conditioning boundary: Environmental conditioning matters because material and measurement behavior can be affected by the test environment. Do not copy a generic temperature, humidity or conditioning time from a marketing page. Use the condition required by the applicable standard, customer procedure or ESD control program, and record it so the result can be interpreted and repeated.
Separate qualification from routine verification. Qualification asks whether the defined design and material are suitable for release. Incoming, lot or periodic verification asks whether repeat production remains within the agreed control plan. The buyer should state the frequency and evidence required for each; a qualification report does not automatically set a universal lot-inspection plan.
Build traceability into the purchase requirement
The report and the physical package should point to the same controlled baseline. Depending on the project, that baseline can include:
- customer part and packaging project number;
- box and divider drawing revision;
- approved sample ID and approval date;
- sheet, formulation or supplier material reference agreed for the project;
- batch, lot or other production traceability reference;
- manufacturing date or defined production period;
- test report number, method revision, conditioning and test locations;
- instrument identification and calibration status where required by the method or quality agreement;
- label, print and ESD identification artwork revision;
- approved cleaning, reuse and retest instructions.
Also define which changes require notice or reapproval. Relevant changes may include material source or formulation, additive or color masterbatch, recycled-content requirement, sheet construction, dimensions, flute direction, tooling, cutting or welding process, макет разделителя, hardware, label, test method, production site or subcontracted operation.
The point is not to create paperwork for its own sake. It is to identify which delivered boxes belong to the same qualified configuration and which do not.
How Should Buyers Approve an ESD Packaging Sample?
Avoid a single email that says only “sample approved.” Record three decisions:
1. Structure and fit
Confirm inner and outer dimensions, divider-cell size, loading orientation, clearance, part removal, lid fit, этикетки, handles and packing for delivery.
2. Handling and mechanical use
Use real parts or controlled surrogates to check movement, scraping, access, carrying, stacking and the intended route. Define any separate transport or reuse validation required by the buyer.
3. ESD evidence
Verify the specified components and locations using the agreed method, conditioning and acceptance rules. Record whether approval covers sheet, converted parts, the assembled package or a defined combination.
After all required gates pass, freeze the drawing, material reference, sample ID, test evidence and approval record. State what the first production lot must reproduce and how an exception or change will be handled. Sample approval confirms only the defined sample and approval scope; it is not a blanket product certification or proof for uncontrolled future lots.

What Jinmai can—and cannot—define
Jinmai manufactures PP hollow sheet and converts it into custom boxes, knife-card dividers, layer pads and other reusable packaging components. For an ESD packaging project, Jinmai can review the manufacturability of the requested box and divider structure, prepare a controlled sample and align project records with the written material, drawing and evidence requirements agreed for the order.
Jinmai does not determine a device’s ESD sensitivity, choose the buyer’s ESD control limits, or turn a color, material label or isolated test into a compliance claim. The device owner, customer or ESD program owner must define and approve the required protective functions, governing documents, test conditions and final acceptance criteria. Any certificate, third-party test or lot-report requirement must be agreed before quotation and sampling.
Ready to turn your requirement into a controlled sample? Send Jinmai the part drawing, quantity per box, handling route, required ESD functions, test reference, conditioning, evidence format and reuse conditions.

Frequently asked questions
Is a black corrugated plastic box automatically ESD safe?
Нет. Color is not proof of low-charging behavior, resistance-related performance or discharge shielding. Approve the identified material and package configuration using the agreed methods, conditions and acceptance criteria.
Can a material name prove ESD compliance?
Нет. Names such as “anti-static PP” or “conductive PP” are incomplete without a required function, governing method, conditions, acceptance rule and traceable test object. The customer specification and ESD control program remain the basis for acceptance.
Is one surface-resistance reading enough to approve the packaging?
Нет. The property, method, electrode or measurement path, sample conditioning, locations, sample quantity and pass rule must be defined. Resistance alone also does not prove low-charging behavior or discharge shielding.
Can a raw-sheet report approve the finished box and dividers?
Not automatically. A raw-sheet report applies to the identified sample under the stated conditions. The buyer must decide whether converted parts, direct-contact dividers, the assembled package or the loaded pack-out also require verification.
What conditioning temperature and humidity should an RFQ specify?
Use the conditions required by the applicable standard, customer method or ESD control program. Do not insert a generic blog value. State the temperature, relative humidity, duration and whether samples are tested as received, after cleaning or after another defined exposure.
Can Jinmai choose the resistance range or certify the customer’s ESD system?
Нет. Jinmai can manufacture and sample against agreed requirements, but the buyer or ESD program owner must define the application-specific functions, methods, limits and approval scope. Required reports or third-party evidence must be specified in the RFQ and contract.
