QR Code Placement Requirements for ESPR Digital Product Passports
ESPR Regulation (EU) 2024/1781 and its delegated acts specify where and how the QR code data carrier for the Digital Product Passport must be placed on products and packaging. Incorrect QR code placement is a compliance failure that can result in products being refused entry at EU customs or withdrawn from the EU market. This page covers the placement rules, size requirements, and durability standards that apply to ESPR DPP QR codes.
General QR Code Placement Rules Under ESPR
ESPR establishes a hierarchy for QR code placement: the data carrier must be placed on the product itself where technically feasible, on the product's packaging where placement on the product is not feasible, and on accompanying documents (such as the product information sheet) where placement on the product or packaging is not feasible. The preference for product-level placement reflects the regulation's intent to maintain DPP accessibility throughout the product's lifetime, including after the original packaging has been discarded.
The data carrier must remain accessible and scannable throughout the product's expected lifetime. For products with a 10-year or longer expected lifetime — which includes most ESPR-regulated product categories — this means the QR code must be durable enough to survive normal use conditions. A QR code printed on a paper label that will degrade within two years does not meet this requirement for a product with a 10-year expected lifetime.
Product-Specific Placement Requirements
| Product Category | Preferred Placement | Minimum Size | Durability Requirement |
|---|---|---|---|
| Batteries (industrial, EV) | Directly on battery casing | 10mm × 10mm | Must survive battery lifetime (10+ years) |
| Smartphones / mobile devices | On device (engraved or permanent label) | 10mm × 10mm | Must survive device lifetime |
| Washing machines / appliances | On product rating plate | 15mm × 15mm | Must survive appliance lifetime (10+ years) |
| Textiles / garments | On care label or hang tag | 10mm × 10mm | Must survive washing and normal use |
| Furniture | On product (underside or back) | 15mm × 15mm | Must survive furniture lifetime |
| Tyres | On tyre sidewall or label | 15mm × 15mm | Must survive tyre lifetime |
| Solar panels | On panel frame or back sheet | 15mm × 15mm | Must survive 25+ year panel lifetime |
QR Code Size and Quiet Zone Requirements
The minimum size for a QR code on an ESPR-regulated product is specified in the applicable delegated act, but the general requirement is that the QR code must be scannable by a standard smartphone camera at a distance of at least 30 centimetres. This typically requires a minimum module size of 0.33mm, which translates to a minimum QR code size of approximately 10mm × 10mm for a Version 3 QR code (29 × 29 modules). For products where the QR code will be scanned at greater distances — such as large appliances or industrial equipment — a larger minimum size applies.
The quiet zone — the white border around the QR code — must be at least 4 module widths on all sides. For a 10mm QR code with 0.33mm modules, this means a quiet zone of at least 1.3mm on all sides. Failure to maintain the quiet zone is one of the most common causes of QR code scan failures in field testing.
Durability and Tamper-Evidence Requirements
ESPR requires that the data carrier remain accessible throughout the product's lifetime. This creates specific durability requirements depending on the product category and its expected use conditions. For outdoor products such as solar panels and tyres, the QR code must be resistant to UV radiation, temperature extremes, and moisture. For food-contact products, the QR code material must comply with food safety regulations. For products that are regularly cleaned — such as washing machines and dishwashers — the QR code must be resistant to cleaning chemicals.
Some delegated acts also require tamper-evidence — the QR code must be designed so that any attempt to remove or replace it is visually apparent. This is particularly relevant for batteries, where the Battery Regulation requires that the QR code be "permanently attached" to the battery and that any removal attempt leaves visible evidence of tampering.
Multiple Data Carriers on the Same Product
ESPR does not prohibit multiple data carriers on the same product. A product may carry both a QR code (for consumer scanning) and an NFC tag (for supply chain scanning) as long as both data carriers link to the same DPP record. However, the regulation requires that there be a single primary data carrier that is accessible to consumers and market surveillance authorities without specialised equipment. The QR code is the de facto primary data carrier for consumer products because it can be scanned by any smartphone camera.
QR Code Placement: The Practical Compliance Challenge
ESPR Article 8(2)(c) requires the data carrier to be "affixed to the product, its packaging, or accompanying documents." The preferred placement is on the product itself — not on the packaging, which may be discarded. For many products, placing a QR code on the product itself is straightforward. For others — particularly small products, products with complex surfaces, and products used in harsh environments — QR code placement requires careful planning.
The QR code must be visible and accessible throughout the product's lifetime. For a washing machine, this means placing the QR code in a location that is visible when the machine is installed — typically on the inside of the door or on the back panel. For a solar panel, this means placing the QR code in a location that is accessible after installation — typically on the back of the panel, in a location that is not covered by the mounting frame. For a tyre, this means placing the QR code on the sidewall in a location that is not subject to road abrasion.
Placement Requirements by Product Category
| Product Category | Recommended Placement | Special Considerations |
|---|---|---|
| Household appliances | Inside door/lid, or back panel | Must be accessible after installation |
| Consumer electronics | Back of device, or inside battery compartment | Must survive normal handling and cleaning |
| Solar panels | Back of panel, away from mounting frame | Must survive 25 years of outdoor exposure |
| Tyres | Sidewall, away from contact patch | Must survive road use; direct part marking recommended |
| Construction materials | On product surface, or on permanent label | Must survive installation and remain accessible |
| Furniture | Underside or back of product | Must remain accessible throughout product lifetime |
| Clothing and textiles | Care label or separate DPP label | Must survive washing; consider NFC for durability |
Minimum Size and Visibility Requirements
The QR code must be large enough to be scannable by a standard smartphone camera at a reasonable distance. GS1 General Specifications require a minimum module size of 0.4mm. For a QR code with 25x25 modules (Version 2), this gives a minimum overall size of 10mm x 10mm. For a QR code with 37x37 modules (Version 5), this gives a minimum overall size of 14.8mm x 14.8mm. In practice, a minimum overall size of 20mm x 20mm is recommended for reliable scanning in real-world conditions.
The QR code must have sufficient contrast to be scannable. Dark modules on a light background (black on white) provides the best contrast. The minimum contrast ratio is 4:1 (dark module reflectance to light module reflectance). Coloured QR codes (non-black modules or non-white background) must be tested to verify that they meet the minimum contrast requirement.
QR Code Size Requirements for ESPR Compliance
The minimum size of a QR code for reliable scanning depends on the scanning distance and the QR code version (which determines the number of modules in the code). For ESPR DPP QR codes, the EU delegated acts will specify minimum size requirements based on the product category and expected scanning distance. As a general guideline, a QR code that must be scannable at 30 cm distance (typical for a handheld scanner or smartphone) requires a minimum module size of 0.3 mm, which translates to a minimum QR code size of approximately 12 × 12 mm for a Version 4 QR code (33 × 33 modules). For QR codes on small products or packaging where space is constrained, Micro QR codes (ISO/IEC 18004:2015, Section 9) or GS1 DataMatrix codes may be used as alternatives.
QR Code Placement on Different Product Types
The placement of the ESPR DPP QR code on the product must ensure that it remains readable throughout the product's lifetime and is accessible without disassembly. For consumer electronics, the QR code is typically placed on the product label on the back or bottom of the device, or on the packaging. For large appliances (washing machines, refrigerators), the QR code is placed on the rating plate that is already required by EU Ecodesign regulations. For textiles and garments, the QR code is placed on the care label or a separate label attached to the garment. For tyres, the QR code is placed on the tyre sidewall. For construction products, the QR code is placed on the product label, the packaging, or the delivery documentation. The delegated act for each product category will specify the exact placement requirements.
QR Code Durability Requirements
The ESPR DPP QR code must remain readable for the lifetime of the product. For products with long lifetimes — such as construction products (50+ years), industrial equipment (20+ years), and vehicles (15+ years) — the QR code must be applied using a durable method that can withstand the expected environmental conditions. Options include: laser engraving (for metal and plastic surfaces), chemical etching (for metal surfaces), ceramic printing (for glass and ceramic surfaces), and UV-resistant ink printing on durable label materials. Manufacturers should test the durability of their QR code application method under the expected environmental conditions — temperature cycling, UV exposure, chemical exposure, and abrasion — before committing to a production method. The ISO/IEC 15415 standard provides a methodology for grading the print quality of 2D barcodes including QR codes.

The placement of the DPP QR code on a product is a critical compliance requirement. A QR code that is inaccessible, unreadable, or removed before end-of-life is a compliance failure. The ESPR implementing regulations will specify the exact placement requirements for each product category, but the general principles are: the QR code must be affixed to the product in a location that is accessible throughout the product's lifecycle; the QR code must be readable by a standard smartphone camera without special tools or disassembly; the QR code must be durable enough to remain readable for the full expected lifespan of the product; and the QR code must be affixed to the product itself, not just the packaging (except where this is technically impractical).
For products where the QR code cannot be affixed to the product surface (such as bulk materials, liquids, or very small components), the ESPR implementing regulations may permit the QR code to be on the product packaging or on a separate document that accompanies the product. However, this exception is expected to be narrow — the general rule is that the QR code must be on the product itself. Manufacturers who believe that their product cannot accommodate a QR code should document the technical reasons and be prepared to justify this to market surveillance authorities.
The QR code must also meet minimum technical specifications: minimum size of 10mm × 10mm (larger for products that will be handled in challenging environments); minimum contrast ratio of 4:1 between the dark modules and the light background; minimum error correction level of Level M (15% error correction); and encoding of the GS1 Digital Link URI in compliance with GS1 standards. A QR code that meets these technical specifications but is placed in an inaccessible location (such as inside a sealed unit) is not compliant.
Frequently Asked Questions
For washing machines, the QR code is expected to be placed on the inside of the door or on the back panel — a location that is accessible throughout the product's lifecycle but not prominently visible during normal use. The QR code must also appear on the product packaging and in the product documentation.
The minimum size for a DPP QR code is 10mm × 10mm. This is the minimum size that can be reliably read by a standard smartphone camera at a distance of 20–30cm. For products that will be handled in challenging environments (high temperature, UV exposure, chemical exposure), a larger QR code (15mm × 15mm or larger) is recommended.
Yes. The DPP QR code can be combined with other QR codes (such as the product's retail barcode or the manufacturer's own QR code) on the product label, provided that each QR code is clearly distinguishable and meets the minimum size and contrast requirements. Using a GS1 Digital Link QR code that encodes both the GTIN and the DPP URI is the recommended approach for combining retail and DPP QR codes.
The QR code must be affixed using a method that ensures it remains readable throughout the product's expected lifespan. For short-lived products, a standard printed label is sufficient. For long-lived products (25+ years), the QR code should be laser-engraved, chemically etched, or printed with UV-resistant inks on a durable substrate. A QR code that becomes unreadable before end-of-life is a compliance failure.
Yes, in most cases. The general rule under ESPR is that the QR code must be on the product itself, not just the packaging. This is because the packaging is typically discarded before the product reaches end-of-life, making the packaging QR code inaccessible to recyclers and repair technicians. The QR code on the packaging is an additional requirement, not a substitute for the product QR code.
