A label is rarely the first thing that comes to mind when reviewing regulatory risk. Yet in pharma, food production, and the chemical industry, the label is often the last line of defence between a compliant product and a costly incident. A missing pictogram, an unreadable font, a batch number applied to the wrong field – these are not minor formatting issues. They can trigger product recalls, block customs clearance, result in regulatory fines, and, in the most serious cases, put end users at risk.
This guide breaks down the specific labelling requirements that apply across three heavily regulated sectors, identifies the most common compliance failures, and explains what it means in practice when choosing label materials and working with a label supplier.
Why labelling compliance deserves its own conversation
Compliance is often treated as a legal department concern, handed off to a specialist and assumed to be someone else's problem. In practice, however, labelling decisions are made at the intersection of procurement, operations, quality assurance, and design – and errors tend to happen precisely at those interfaces.
The stakes differ by sector. In pharmaceuticals, a serialisation error can mean a product cannot be scanned at the point of dispensing, and must be withdrawn from the supply chain. In food production, an incorrectly declared allergen can lead to a public health incident and a full market recall. In the chemical industry, a missing UFI code or an incorrectly sized hazard pictogram can result in an immediate ban on sale within the EU.
What these scenarios share is that the label failure is often the visible symptom of a process failure upstream – in specification, supplier communication, or quality control. Understanding the regulatory requirements in detail is the first step to building a process that prevents these failures.
Pharmaceutical labelling: precision under the microscope
The pharmaceutical sector operates under some of the most demanding labelling regulations in the world. Two frameworks in particular define labelling practice for products placed on the EU market.
The EU Falsified Medicines Directive (FMD), which became fully operational in 2019, requires that prescription medicines carry a unique identifier – a 2D DataMatrix code encoding the product code, serial number, batch number, and expiry date. This code must be printed at a minimum resolution that allows reliable scanning in supply chain environments, and must be accompanied by a tamper-evident feature that shows visually if the packaging has been opened.
The practical implications go beyond just printing a code. Serialisation requires integration between label production, line management systems, and aggregation databases. Any mismatch between the data on the label and the data in the system – even a transposed digit in a batch number – can result in the product being flagged as falsified at the point of verification.
GMP Annex 1 and Annex 15 set out requirements for label reconciliation, version control, and the handling of label waste. In a GMP-compliant environment, every label printed must be accounted for. Excess or damaged labels cannot simply be discarded – they must be destroyed and documented. This places significant demands on label production and application processes, particularly for small batch runs or multiproduct lines.
Material requirements add another layer of complexity. Pharmaceutical labels must survive the full lifecycle of the product, which can include:
- cold chain storage (down to -20°C or lower for certain biologics);
- autoclaving or gamma irradiation for sterile products;
- immersion in water, alcohol, or cleaning agents during handling; or
- glass, HDPE, or aluminium surfaces, each with different adhesion characteristics.
Common compliance failures in pharma labelling include font sizes that fall below the minimum legible threshold, missing or incorrect language versions for multi-market SKUs, and adhesive failure on glass vials under cold chain conditions – a failure that is not just cosmetic, but renders the product unidentifiable in the supply chain.
Food labelling: balancing regulation and shelf appeal
Food labelling in the EU is governed primarily by Regulation (EU) No 1169/2011 on the provision of food information to consumers, commonly known as the FIC Regulation. It defines a set of mandatory particulars that must appear on pre-packaged food products, and sets out the conditions under which they must be displayed.
The mandatory elements include:
- name of the food,
- list of ingredients,
- any allergens present (which must be emphasised – typically in bold – within the ingredients list),
- net quantity,
- date of minimum durability or use-by date,
- any special storage conditions requirements,
- name and address of the food business operator,
- country of origin, where required,
- instructions for use, where required, and
- nutrition declaration.
The allergen declaration requirement deserves particular attention. The FIC Regulation identifies 14 allergen groups – including cereals containing gluten, milk, eggs, nuts, and sulphur dioxide – that must be declared whenever present as ingredients or as processing aids. The emphasis requirement (bold, italic, underline, or different colour) is mandatory, not optional. Labels that list allergens without emphasis are non-compliant, regardless of how clearly the information is otherwise presented.
The distinction between 'best before' and 'use by' dates is also a legal matter, not a commercial preference. 'Use by' dates apply to microbiologically perishable foods where safety is the concern. 'Best before' dates apply to products where quality rather than safety is the issue. Using the wrong date format is a compliance error with direct consumer safety implications.
From a material perspective, food labels face a challenging environment too. Labels applied to products that go into cold storage must maintain adhesion at low temperatures and recover legibility after condensation. Labels on packaging that goes through washing or ice contact must resist moisture. Labels applied to flexible packaging – pouches, shrink sleeves, modified atmosphere packs – must flex without cracking or lifting at the edges.
Starting 12 August, 2026, the European Union's Packaging and Packaging Waste Regulation (PPWR) imposes strict, new, and legally binding restrictions on substances used in packaging. For food-contact packaging, PFAS levels must be below 25 ppb for individual substances or 250 ppb for the sum of PFAS. Additionally, the combined total of lead, cadmium, mercury, and hexavalent chromium is capped at 100 mg/kg for all packaging types.
While food, feed, and medicinal products are exempt from the Digital Product Passport (DPP) under the Ecodesign for Sustainable Products Regulation (ESPR), the PPWR mandates that all packaging – including that used for food and pharmaceuticals – must eventually have its own digital passport and standardised QR code labelling by 12 August, 2028.
Chemical labelling: GHS/CLP and the language of hazard
Chemical labelling in the EU is governed by the CLP Regulation (EC) No 1272/2008, which implements the Globally Harmonised System of Classification and Labelling of Chemicals (GHS) in European law. CLP applies to substances and mixtures placed on the EU market and sets out precise requirements for how hazards must be communicated on the label.
The mandatory CLP label elements are:
- product identifier,
- supplier details,
- hazard pictograms,
- a signal word (either 'Danger' or 'Warning', depending on severity),
- hazard statements (H-statements),
- precautionary statements (P-statements), and
- since 2021 for consumer-facing mixtures – the Unique Formula Identifier (UFI).
The UFI is a 16-character alphanumeric code that links the product formulation to the data submitted to the European Chemicals Agency (ECHA) for poison centre notification purposes. Its introduction was specifically intended to improve emergency response – when a person is exposed to a hazardous mixture, the poison centre can use the UFI to retrieve precise formulation data and advise treatment accordingly. A product sold without a UFI where one is required is non-compliant and cannot legally be placed on the EU consumer market.
Pictogram sizing requirements are a frequent source of compliance failures. CLP specifies minimum label sizes based on the volume of the package, and minimum pictogram dimensions as a proportion of the label area. On small containers – vials, cartridges, sample bottles – fitting all mandatory elements within the available space while meeting size requirements demands careful label design, often requiring extended content label formats.
From a materials standpoint, chemical labels operate in arguably the most demanding environments. Labels on industrial cleaning products, solvents, lubricants, or process chemicals must resist the very substances they are labelling. Requirements typically include:
- resistance to solvents, oils, fuels, and aggressive cleaning agents;
- UV resistance for products stored or used outdoors;
- performance across wide temperature ranges, from cold storage to high-temperature process environments; and
- adhesion to metal, glass, HDPE, and PP surfaces – many of which are low-energy and inherently difficult to bond to.
Polyester and polyimide film labels with aggressive permanent adhesives are the standard solution for the most demanding chemical applications. For extreme conditions – labels that must survive autoclaving, prolonged solvent immersion, or outdoor weathering beyond five years – specialist substrates and adhesive systems are required, and these decisions should be made at the specification stage, not after a field failure.
Cross-industry considerations: what all three sectors share
Despite their differences, pharma, food, and chemical labelling share several practical challenges that any compliance-focused operation will encounter.
Multi-language and multi-market labelling is a reality for most manufacturers selling across the EU. Managing label variants – ensuring the right language version reaches the right market, controlling version changes, preventing obsolete labels from reaching the line – is a process management challenge as much as a design one. Extended content labels, which open (booklet labels) or peel (peel-off labels) to reveal additional text panels, are widely used in all three sectors to accommodate mandatory multi-language content without increasing label size or reducing font legibility below the legal minimum.
The EU Declaration of Conformity (DoC) (mandatory from 12 August, 2026) is a significant new administrative requirement that arrives with the PPWR. Every unique packaging type placed on the EU market must be backed by a technical documentation file and a signed Declaration of Conformity (DoC). This is a legally binding self-declaration confirming the packaging meets all safety and sustainability requirements.
Digital integration is increasingly crossing from value-added to mandatory. In pharma, serialisation is already the law. In food, QR codes linking to nutrition and sustainability data are moving from voluntary best practice toward being a regulatory requirement. In chemicals, the UFI is a statutory requirement, and machine-readable submission of formulation data to ECHA is part of the compliance framework. The label is becoming an interface between the physical product and a digital compliance record – and label specifications need to reflect that.
Label verification and quality control cannot be an afterthought. Print quality inspection systems – cameras and scanners integrated into print-and-apply lines – are standard in pharmaceutical manufacturing and increasingly expected in food and chemical production. At a minimum, every label run should include a process for verifying that the correct version was applied, that codes are readable, and that mandatory elements are present and legible.
Supplier qualification matters more than it is often given credit for. A label supplier working in regulated sectors should be able to demonstrate ISO 9001 certification as a baseline, with GMP-compliant production capability for pharmaceutical customers. They should maintain documented material qualification records – evidence that the substrate and adhesive combination has been tested under the conditions your application requires – and be able to support you through change management when formulations, substrates, or regulatory requirements change.
Compliance starts at the specification stage
The most expensive label compliance failures are those that are discovered late – during a regulatory audit, a customer complaint, or a field recall. The least expensive are those that are designed out at the specification stage, before a label has even been printed or applied.
That means treating the label specification as a compliance document, not just a design brief. It means briefing your label supplier on the regulatory environment your product operates in, the surfaces and conditions the label will face, and the verification requirements you need to meet. It means building label version control into your quality management system, not managing it informally in a spreadsheet.
A well-specified label, produced by a qualified supplier, using the right material for the application, is not just a compliance asset – it is a risk management asset. In regulated industries, the two are the same thing.
