Mandatory, voluntary, permitted or prohibited?
A comparison matrix for the legal statuses that can sit behind the same small area of printed packaging.
Why the mandatory–voluntary binary fails
Packaging labels are often sorted into mandatory or voluntary. That split is useful and not enough. A material code may be mandatory without making an environmental claim. A certification seal may be voluntary to adopt but prohibited for an unlicensed user. A recyclability statement may be permitted only when infrastructure criteria are met. A financing mark may have been mandatory under an earlier scheme and become optional or prohibited after reform. The question is not only whether a mark must be printed, but what legal relation governs its use.
The matrix distinguishes seven positions. They can coexist on one package because they attach to different statements, actors and instruments. Assign status to the specific mark or claim in the specified market, never to the package as a whole.
Status matrix
| Status | Legal meaning | Typical evidence | Illustrative packaging example | Principal error |
|---|---|---|---|---|
| Mandatory and presently applicable | An operative public-law rule requires the information or symbol on covered packaging. | Instrument, scope, triggering event and obligated-party analysis. | France's Triman and Info-tri requirements while the French rules remain in force. | Assuming the brand owner is necessarily the party legally bound. |
| Adopted but not yet applicable | The legislature has fixed the duty in final text, but a future date or implementing measure controls application. | Final instrument plus commencement or dependent-act formula. | PPWR harmonised sorting and reuse labels. | Publishing the earliest date as if the implementing act already existed. |
| Voluntary scheme | No general public-law duty compels participation; users that join are bound by licence and classification rules. | Scheme standard, licence, assessment record and territory. | How2Recycle, OPRL and many compostability certification marks. | Treating scheme approval as a statutory safe harbour. |
| Permitted conditional claim | Law allows a representation only where specified facts, tests or qualifications support it. | Claim substantiation matched to the conveyed meaning. | An unqualified recyclable claim under the FTC Green Guides where substantial-majority access is established. | Substituting a design certificate for evidence of local collection and processing. |
| Restricted or prohibited representation | The symbol or wording is unlawful for a defined package or absent a condition. | Prohibition, blacklist or deception rule and any exception. | California's chasing-arrows restriction under SB 343; generic EU claims within Directive (EU) 2024/825. | Calling the underlying material or package “banned” when the law regulates only the representation. |
| Commercially expected but not legally required | Retail, procurement or sector practice makes a mark practically important without converting it into law. | Contract, retailer standard or tender specification. | A retailer requiring OPRL participation from suppliers. | Describing a contractual condition as a national mandate. |
| Proposed, stalled or abandoned | The measure is part of the policy record but supplies no present obligation. | Legislative procedure and latest official status. | The blocked EU Green Claims Directive proposal and earlier UK labeling proposals that were not enacted as announced. | Writing “will require” where the correct verb is “would require”. |
Status attaches to a proposition
The chasing-arrows graphic shows why the unit of analysis matters. In one context it encloses a resin identification code. In another it communicates recyclability. In a third it is part of a licensed scheme label. A statute may require a resin code while prohibiting the arrows enclosure unless recyclability criteria are met. The code and the claim occupy different legal statuses even when a consumer sees one combined mark.
The same separation applies to compostability. A jurisdiction may require a compostable product to carry a prescribed disposal statement, permit a certified compostability seal, and prohibit an unqualified “biodegradable” claim. “Compostable labelling is mandatory” cannot express those three relations. A complete record identifies the object, the representation, the authority, the condition and the actor.
Certification does not collapse the matrix
Certification can be a legal gateway, a source of evidence, or a private commercial credential. It is a gateway where law permits a badge only under a recognised scheme. It is evidence where a regulator asks whether a performance claim was substantiated. It may be largely irrelevant where the question is collection access, the general impression of the advertisement, or a proposition outside the certificate’s scope. A third-party seal therefore changes the evidence column more often than the legal-status column.
Interaction with enforcement
Record status and enforcement separately. A mandatory rule may still apply while its principal enforcer is restrained. A voluntary claim can still attract penalties under general consumer law. A proposal can influence enforcement expectations without having legal effect. The matrix records the source of the norm. The litigation tracker records whether and how that norm is being contested or applied.
Minimum data fields for comparison
A comparative dataset should store, at minimum: jurisdiction; mark or claim; product and packaging scope; legal status; public instrument or private scheme; obligated or licensed party; substantive condition; date; enforcement route; evidence required; transition rule; and last verification date. A single “mandatory” field is a display convenience derived from those data, not the authoritative record.

Note on sources and verification
The seven-position matrix is an analytical framework developed for this Atlas. The examples are illustrations of the categories, not exhaustive legal summaries; the linked Theme 2 and Theme 4 articles provide their qualifications. “Commercially expected” is deliberately separated from law because retailer and procurement requirements vary by contract and are not verified here as market-wide rules.
