oSIST prEN 50777:2026 is a draft European Standard from CLC for measuring and calculating recycled content in smartphones, mobile phones other than smartphones, cordless phones and slate tablets. oSIST prEN 50777:2026 tells manufacturers how to establish traceability, calculate recycled content at part and product level, and report the result for assessment and ecodesign purposes.
What does oSIST prEN 50777:2026 specify?
oSIST prEN 50777:2026 specifies technical methods for determining recycled content in the listed device types, using supply-chain evidence, part-level calculations and product-level aggregation. The scope also says the same approach can be applied, when relevant, to other audio, video and multimedia systems and equipment.
The document is organized into five clauses plus one informative annex. Clause 4 is the core method for assessment, calculation and traceability, while Clause 5 defines how the assessment must be reported.

| Annex ZZ | Relationship between this European Standard and the ecodesign requirements of Regulation (EU) 2023/1670 aimed to be covered |
What are the key requirements of oSIST prEN 50777:2026?
oSIST prEN 50777:2026 requires the recycled content assessment to be done from the manufacturer’s position and to cover both pre-consumer and post-consumer recycled material. In practice, the manufacturer has to build an evidence trail that supports the claim, not just a mass calculation.
Traceability and chain of custody
Clause 4.2 makes traceability a prerequisite. Recycled material inputs have to be tracked through documented chain-of-custody (CoC) procedures from the point where the recycled material acquires its status, through the supply chain, to its final use in the product.
This matters because the claim must connect administrative records to the physical flow of material. If different CoC models are used, the model with the lowest level of physical presence across the supply chain applies to the claim, and approaches such as book-and-claim are not included.
Supply-chain evidence and material input assessment
Clause 4.3.1 requires recycled input assessment to rely on declarations from materials and parts suppliers. The document also says the origin of the recycled material, the recycled quantity, and whether it is pre-consumer or post-consumer must be documented.
EN IEC 82474-1:2025 is identified as a format that may be used for those declarations. In practice, this helps teams collect supplier data in a structured way that can be checked later.
Material grouping and exclusions
Clause 4.3.2 defines the material clusters used for this product group, including steel, aluminium, magnesium, copper, plastics by polymer class, glass, cobalt, lithium, nickel, gold, silver, tin, indium and platinum group metals. Where a material does not fit one cluster clearly, it is assigned to the cluster of the dominant constituent by mass, or treated as “other materials”.
Parts may be excluded from allocation to specific clusters for reasons such as size or weight, complexity, or administrative and legal issues. If a part is excluded, the report must justify that decision and identify its mass, so the final result stays transparent.
Calculation at part level and product level
Clause 4.4 sets separate formulas for pre-consumer recycled content, post-consumer recycled content and total recycled materials content in a part. Clause 4.5 then aggregates the part results to the product level using the mass of each part and the total product mass.
That means the calculation is not a simple average. Larger parts influence the product figure more than smaller parts, and the total product mass includes all parts whether or not they were counted in the recycled content calculation.
Consistency and reporting
Clause 4.5 requires a consistency check so that the product’s pre-consumer and post-consumer figures add up to the total recycled content. Clause 5 then requires the assessment to be documented, and if the total recycled content is communicated, it must be reported together with the pre-consumer and post-consumer figures.
The assessment report in Clause 5.2 covers the assessor, date and place, the applied standards and regulatory requirements, the product model, included and excluded parts, supplier and recycling facility details, masses, calculated results, assumptions and references. Table 1 and Table 2 give example reporting layouts.
What terms does oSIST prEN 50777:2026 define?
- Primary material - virgin material that has not been previously used or processed beyond its own production.
- Recycled content - the proportion by mass of recycled material.
- Recycled material - material reprocessed from end-of-life products or waste and ready for use in manufacturing.
- Pre-consumer material - recycled material recovered from material discarded during a manufacturing process.
- Post-consumer material - recycled material recovered from end-of-life products or waste from end-users, including returns from the distribution chain.
- Chain of custody (CoC) - the process that transfers, monitors and controls inputs and outputs as they move through the supply chain.
- Traceability - the ability to trace the origin, history, application, location or characteristics of a product or material.
- Part - a hardware, firmware or software constituent of a product; for this document, firmware and software are not relevant.
Who uses oSIST prEN 50777:2026?
oSIST prEN 50777:2026 is for manufacturers of smartphones, mobile phones other than smartphones, cordless phones and slate tablets who need a documented recycled content figure. It is also used by suppliers that provide recycled material declarations, and by compliance, product stewardship, quality and audit teams that collect evidence and prepare reports.
In practice, the standard supports ecodesign assessments, supplier data collection, product documentation and verification of recycled content claims.
Which standards are used with oSIST prEN 50777:2026?
oSIST prEN 50777:2026 cites EN 45557:2020 as the main normative reference. EN 45557:2020 provides the general method for assessing recycled material content in energy-related products and identifies the chain-of-custody models used in the assessment.
Clause 4.3.1 and Clause 5.2 also point to EN IEC 82474-1:2025 as a useful format for material declarations. That helps organizations structure supplier declarations in a way that supports the recycled content calculation.
What does the oSIST prEN 50777:2026 document contain?
oSIST prEN 50777:2026 contains a step-by-step assessment method, calculation formulas and reporting requirements for recycled content. Clause 4 covers traceability, supply-chain information, material grouping, part-level calculations and product-level aggregation.
Clause 5 and the example tables show how to document the result, including product mass, assessed materials, recycled fractions and assumptions. Annex ZZ links the standard to the ecodesign requirements of Regulation (EU) 2023/1670 and shows where the clauses are intended to support conformity assessment.

158 4 Assessment steps
159 4.1 General
160 The recycled content assessment produces a part or product-level recycled content figure. The assessment is
161 conducted from the position of the product manufacturer, considering both pre-consumer and post-consumer
162 recycled material.
163 The following steps shall be followed:
164 Step 1. Establish traceability and assess recycled material inputs
165 The traceability of recycled materials shall be established and documented through chain-of-custody procedures
166 in accordance with 4.2. Information on recycled material inputs shall then be obtained from the supply chain in
167 accordance with 4.3.
168 Step 2: Calculate the percentage of recycled content
169 The percentage of recycled content shall be calculated first at part level in accordance with 4.4, and shall be
170 aggregated to product level in accordance with 4.5 whenever a product level recycled content figure is reported.
171 4.2 Traceability
172 Traceability of recycled materials is a pre-requisite for calculating and verifying recycled materials content.
173 The traceability of recycled material shall be ensured through documented CoC procedures for tracking recycled
174 material inputs within defined system boundaries from the point of origin of the recycled material (including, the
175 recycling facility or equivalent processing facilities at which the material acquires its recycled status) through
176 each step of the supply chain to their final application in the product.”
177 Procedures (management system) for the identification and the tracking of recycled content declarations shall
178 be appropriately documented and available for independent verification.
179 Where recycled and primary materials are mixed during manufacturing or material processing, traceability shall
180 be demonstrated through accounting methods that ensure the quantity of recycled content declared can be
181 verified against verified recycled inputs, taking into account outputs, losses, and defined accounting periods.
182 The CoC model shall demonstrate that the administrative record flow is connect
