If you do business in the EU market, whether selling beauty products, 3C electronics, food, or daily necessities, you have most likely encountered the requirement of “heavy metal compliance for packaging”. Many people find it strange at first: they are just boxes and bags for holding things, why regulate heavy metals in them? In fact, this is a mandatory market access rule that has been implemented in the EU market for more than 20 years. If you fail to comply, the lightest consequence is cargo detention and rectification, and the heaviest is fines or even a ban on entering the market.
In this article, we start from the most basic concepts, all the way to being able to judge compliance by yourself and avoid common pitfalls. Whether you are a novice just getting into the EU market, or an experienced seller who wants to solidify your compliance work, you can find useful information here.
I. First, understand: what this rule is, and why you should attach importance to it
1. It is not an optional eco-label, but a mandatory access requirement
Many people think that heavy metal restrictions on packaging are some kind of “green certification” that is optional, but that is completely not the case — this is a mandatory requirement that all packaging placed on the EU market must comply with, and it is a hard threshold for market access.
The current rule is based on the EU (94/62/EC, amended in 2018). As a directive, it is currently implemented through the local regulations of each member state; when enterprises judge compliance, they must not only look at the limits at the EU level, but also confirm the document requirements of the target member state/UK. This rule has been implemented in the EU for more than 20 years. The newly released EU (PPWR) is a directly applicable regulation, and the implementation standards of member states will be more unified, with the core limit of 100ppm remaining unchanged; the specific effective date, transition period, and UK local implementation rules shall be subject to the official text and local requirements, and enterprises can make compliance preparations in advance.
2. Why focus on heavy metals in packaging
Simply put, it is because too much packaging is used and discarded too quickly, and heavy metals are difficult to degrade naturally, so they easily spread into the environment.
According to public statistics from the European Environment Agency, the EU generates tens of millions of tons of packaging waste every year, most of which is incinerated, landfilled, or enters the recycling system after use. If packaging contains heavy metals, they will be emitted with exhaust gas during incineration, seep into soil and groundwater during landfilling, and if they are made into new packaging or other products along with recycled materials, they will spread downstream all the way. Long-term accumulation is harmful to both the environment and human health. Therefore, restricting heavy metals in packaging from the source is a very important part of the EU’s environmental protection system.
3. Which markets must comply
The scope of application of this rule is not only the 27 EU member states, but also Norway, Iceland, and Liechtenstein in the European Economic Area (EEA) — these countries have unified internal market rules with the EU, so they must also comply.
In addition, the UK needs to be mentioned separately: after Brexit, the UK has an independent regulatory system, and the limit logic is generally close to that of the EU, but compliance declarations, regulatory references, responsible entities, and document archiving need to be prepared separately according to the UK system.
II. Core Rules: 4 Heavy Metals + 100ppm Total Limit
Now that we have clarified why to comply and which markets require compliance, let’s talk about the most core content: exactly which heavy metals are regulated, what the limits are, and what counts as meeting the standard.
1. The 4 regulated heavy metals mostly come from raw material residues
At present, there are 4 heavy metals explicitly regulated by the EU. They are rarely actively added by enterprises, and mostly come from residues of pigments, raw materials, or processes:
• Lead (Pb): The most common sources are color inks, stabilizers for plastic processing, coatings on metal surfaces, and impurities in recycled materials — old plastics and old paper may have residual lead-containing materials from early years, which are difficult to completely remove during recycling.
• Cadmium (Cd): It mostly appears in particularly bright pigments such as yellow, red, and orange, as well as in PVC (polyvinyl chloride) plastics and metal electroplating layers. Many materials have now been replaced with cadmium-free formulations, but investigation is still required.
• Mercury (Hg): Mercury is almost never actively added in modern packaging. It mostly comes from pollution during raw material mining or processing, or from materials using old processes. Although the probability of occurrence is low, it is still within the scope of regulation.
• Hexavalent chromium (Cr(VI)): A special emphasis here: only chromium in the valence state of “hexavalent chromium” is regulated, not all chromium elements. It often appears in metal anti-rust coatings, leather tanning agents, and some yellow pigments, and its toxicity is much higher than that of chromium in other valence states.
2. 100ppm is the total limit, not 100 for each type
When many people first come into contact with this rule, the easiest thing to get wrong is the limit logic: 100ppm is the upper limit of the total content of the 4 heavy metals, not a 100ppm quota for each heavy metal.
Let’s put it in plain terms: ppm is one part per million, 100ppm = 100mg/kg = 0.01%, which means that in 1 kilogram of packaging material, the total weight of these 4 heavy metals cannot exceed 100 milligrams.
Take a very simple example of non-compliance: if a certain packaging has a lead content of 70ppm, cadmium 20ppm, mercury 5ppm, and hexavalent chromium 10ppm, the total is 105ppm, which is considered non-compliant — even if none of the individual types reach 100ppm, it is still not acceptable.
3. Judged by the smallest detachable unit, whole-package average dilution is not allowed
Some people may think: then I can mix the parts with high heavy metal content with the parts with low content, and the average will meet the standard? The answer is absolutely no.
The EU’s judgment rule is calculated based on the smallest detachable unit. Each unit must meet the standard individually, and whole-package averaging cannot be used for dilution. What is the “smallest detachable unit”? It means using simple mechanical methods such as cutting, scraping, and tearing to disassemble until it can no longer be divided into small pieces of different materials. For example, for a color-printed paper box, if the tape on the surface can be torn off, the tape is a separate unit, and the paper box itself is another unit; both must meet the standard. If the ink cannot be scraped off, it is counted as the same unit as the paper base.
There is another special case: if it is water-containing packaging material (such as wet cushioning pulp), it will be calculated based on the dry weight after drying. This is a unified laboratory operation, and you do not need to process it yourself in advance.
4. All packaging components must be counted, no matter how light they are
Another point that is easy to miss: as long as it is a component delivered together with the packaging, no matter how light it is, it must be included in the testing scope of the corresponding unit.
For example, ink, coatings, adhesives, labels, sealing tape, hang tags, anti-counterfeiting labels, cushioning foam, outer bags of desiccants, and even the self-adhesive layer for sticking labels are all part of the packaging, and cannot be ignored because they are “too small and too light”.
III. Which Packaging Is Regulated, and Which Are Exceptions
After finishing the core rules, let’s draw a clear boundary: exactly which packaging falls within the scope of regulation, which does not need to be regulated, and which are legally exempt.
1. Judgment criteria for regulated packaging
In fact, the standard for judging whether something counts as “packaging” is very simple: as long as it is an item used to contain, protect, handle, deliver, or display goods, no matter what material it is made of or which link it is used in, it counts as packaging.
Common types include inner packaging (usually, containers such as cosmetic bottles and food bags that directly contact goods are inner packaging), sales packaging (color boxes, gift boxes sold to consumers), transport packaging (express boxes, pallets, bubble wrap), and service packaging (takeaway boxes, shopping bags). Whether it is paper, plastic, glass, metal, wood, leather, or composite materials, as long as it is packaging, it must meet the heavy metal restriction requirements.
2. Three types of clearly unregulated situations
Of course, not all things with packaging attributes are regulated. There are three types that are clearly outside the scope of regulation:
The first type is indivisible components of the product itself: only indivisible parts that are indeed part of the product itself, mainly undertake the product’s use function, and do not undertake packaging functions such as containment, protection, handling, delivery, and display are not included in the scope of packaging regulation. When the boundary is doubtful, it shall be evaluated strictly in accordance with packaging requirements.
The second type is reusable turnover boxes and pallets that are only circulated within the enterprise and not placed on the market, such as plastic boxes for transporting parts in factory workshops and turnover pallets in warehouses. As long as they are not sold to customers, they do not need to comply.
The third type is packaging only exported to regions outside the EU, which naturally does not need to comply with EU rules.
3. Only these 3 types are legally exempt
In addition to unregulated situations, there are three types of legal exemption scenarios — note that only these three types are explicitly stipulated by law as not needing to meet the 100ppm limit, and all have strict prerequisites. You cannot arbitrarily claim exemption by yourself, and complete supporting documents must be retained:
1. Packaging for the transport of dangerous goods: Exemption may apply only on the premise of meeting the applicable dangerous goods transport packaging regulations (such as ADR for road transport, IMDG for sea transport, etc.) and being able to provide complete supporting documents, because the core requirement of dangerous goods transport packaging is safety, which has a higher priority.
2. Special packaging for medical devices: Exemption is only possible if three conditions are met at the same time: direct contact with medical devices, no alternative solutions with low heavy metals, and compliance with EU medical device regulations. Not all medical packaging is exempt.
3. Lead crystal glass packaging: Glass packaging containers that meet EU crystal glass standards (such as crystal glass bottle bodies or bottle caps) are exempt because the material itself needs to contain lead to achieve the crystal effect. The exemption is based on the material meeting the corresponding standards and regulatory conditions, and is not applicable to any high-end or decorative packaging.
4. Never believe these “false exemptions”
Many people who are new to this think that certain situations can be exempted, but they are actually misunderstandings. We call them “false exemptions”, and there are 4 most common ones:
• Packaging made of recycled materials: Many people think it is normal for recycled materials to contain heavy metals and that there should be leniency, but there is actually none — heavy metals brought in by recycled materials must still meet the 100ppm requirement, and there are no special exemptions.
• Small-batch, sample, promotional, and only online-sold packaging: As long as it is placed on the EU market, no matter the quantity, whether it is a sample or a genuine product, whether it is sold online or offline, it must meet the requirements, which has nothing to do with quantity or channel.
• Transport pallets and cartons delivered with goods: Some people think that transport packaging is for transporting goods and does not count as packaging. In fact, as long as the transport packaging is delivered to the buyer together with the goods, it belongs to sales supporting packaging and must meet the requirements.
• No need for compliance if the customer doesn’t require it: This is the most common misunderstanding — this requirement is mandatory under EU law, not an optional requirement from the customer. Even if the customer doesn’t mention it, as long as your packaging enters the EU market, it must comply, otherwise you will still be held responsible if found out.
IV. Don’t Confuse It with Other EU Environmental Rules
Friends who are new to EU compliance often confuse the heavy metal requirements for packaging with several other common environmental regulations. In fact, their regulated objects and goals are completely different, and they cannot replace each other. We have compiled a comparison table so you can tell them apart at a glance:
| Regulation Name | Regulated Object | Core Logic | Can It Replace Packaging Heavy Metal Requirements? |
| Packaging Heavy Metal Rules | All packaging placed on the EU market | Total content of 4 heavy metals ≤100ppm, judged by the smallest detachable unit | —— |
| RoHS Directive | Electrical and electronic products themselves | Individual heavy metal limits are set for homogeneous materials, regulating harmful substances in the product itself | No |
| REACH Regulation | All chemicals, Substances of Very High Concern (SVHC) | Notification, assessment, and information transfer of chemicals | No |
| Food Contact Materials Regulations | Packaging/materials that come into contact with food | The amount of harmful substances migrating into food meets the limit | No |
Supplementary note: RoHS only applies to electrical and electronic products themselves, and its test reports cannot cover the heavy metal requirements of packaging; food contact materials regulations regulate the migration of harmful substances into food, which is parallel to the total content requirements of packaging materials themselves, and the two types of rules cannot replace each other; REACH and this rule may apply at the same time. If packaging materials trigger REACH restrictions or the obligation to transfer information on Substances of Very High Concern (SVHC), they still need to be fulfilled separately, but REACH compliance declarations cannot replace special testing for heavy metals in packaging. In addition, the packaging heavy metal rules do not mandate the CE mark, and the CE mark cannot prove compliance with this requirement, nor can “common industry practices” be used as a legal basis for compliance.
V. Beginner’s Practice: 4 Steps to Judge Whether Your Packaging Is Compliant
Master the following 4-step beginner’s judgment method, and you can conduct a preliminary assessment of the compliance of your packaging by yourself:
Step 1: First confirm whether it is within the scope of supervision
First ask yourself three questions:
1. Will my packaging eventually be placed on the EU/EEA/UK market? If yes, it most likely needs to comply.
2. Does my packaging fall into the 3 types of legal exemption scenarios mentioned above? If yes, prepare the corresponding supporting documents according to the exemption requirements.
3. Is my packaging only used within the enterprise and is turnover packaging that does not enter the market? If yes, it does not need to comply.
Step 2: Disassemble the packaging into the smallest testable units
After confirming that compliance is required, the next step is to disassemble the packaging into the smallest detachable units to ensure that each unit is covered.
The disassembly method is very simple: use ordinary mechanical methods such as cutting, scraping, and tearing to disassemble until it can no longer be divided into small pieces of different materials. For example, a color-printed plastic bottle can usually be disassembled into: PET bottle body (with printing, counted as one unit if the ink cannot be scraped off), PP bottle cap, paper label, and self-adhesive layer.
Special reminder for several small parts that are easy to miss: sealing tape, hang tags, anti-counterfeiting labels, blister aluminum foil, desiccant outer bags, and cushioning foam. All of these must be counted and cannot be missed.
Step 3: Quickly screen high-risk materials
After disassembly, you don’t need to test all materials at the same time. You can first conduct layered screening according to risk levels to save time and cost:
• High-risk materials: color inks/coatings, PVC plastics, leather/artificial leather, high-proportion recycled materials, metal anti-rust layers, bright pigments — these materials have a higher probability of heavy metal exceeding the standard, and compliance should be confirmed first.
• Low-risk materials: transparent/natural virgin plastics, unprinted virgin paper, colorless glass, uncoated metal — these materials themselves have a low probability of heavy metal exceeding the standard, and can be treated as low priority, but supplier compliance declarations, material descriptions, or sampling inspection basis must still be retained; once recycled materials are used, suppliers are changed, or batch abnormalities occur, timely re-inspection should still be carried out.
Step 4: Obtain compliance certification
After screening, you need to obtain the corresponding compliance certification. There are two common methods:
The first is to have the supplier provide: including a compliance statement specifically for EU packaging heavy metal requirements, plus test reports for the corresponding material or batch.
The second is to send for third-party testing: if the supplier cannot provide it, or you have doubts about the report, you can send the sample to a qualified third-party laboratory for testing. You don’t need to do the experiment yourself, just send the sample as required.
Note: Different EU environmental regulations have different regulatory objectives and scopes of application, and compliance documents of other regulations cannot be mixed (see Chapter IV for specific differences).
VI. Advanced Pitfall Avoidance: Details That Semi-Professionals Must Know
If you need to further safely avoid compliance risks, the following semi-professional judgment details can help you avoid the vast majority of common problems.
1. How to read test reports without being tricked
Many people get a test report and feel relieved just by seeing the word “qualified”. In fact, many pitfalls are hidden in the details of the report. Focus on these points:
• Check the test object: Is it tested according to the smallest detachable unit? If it is the average value tested by mixing the whole package together, this report is invalid.
• Check test items: Are all 4 heavy metals tested? Is hexavalent chromium tested separately? Some reports only test total chromium, not hexavalent chromium, which does not meet the requirements, because only hexavalent chromium is regulated.
• Check result calculation: Is it judged based on the sum of the 4 heavy metals? Is the unit ppm or mg/kg? Don’t mistake individual limits for the total limit.
• Check matching degree: Are the sample description, material, and batch in the report consistent with the packaging you actually use? Don’t use reports from other customers or other products provided by the supplier to make up the number, because when checked, they won’t match at all.
• Check validity: The regulations do not set a unified statutory validity period for test reports. Enterprises can set an internal re-inspection cycle according to their own quality control requirements; once materials, formulas, suppliers, inks, or the proportion of recycled materials change, or relevant standards are updated, re-testing must be carried out.
• There is another small detail: “Not Detected (ND)” in the report does not mean that there is absolutely no heavy metal, but that the content is lower than the detection limit of the test method — for example, if the detection limit is 2ppm, not detected means less than 2ppm, not 0. This should be judged in combination with the actual situation.
2. Compliance difficulty and selection logic for different packaging
Different types of packaging have very different compliance difficulties, and you can choose according to your own needs:
• Low difficulty: Unprinted natural virgin packaging, such as transparent plastic bags and blank cartons, usually has low heavy metal risk and low cost. If there are no special design requirements, you can give priority to them, but you still need to ask the supplier for a compliance statement or retain sampling inspection basis.
• Medium difficulty: For paper/plastic packaging with color printing, ink is the core risk point, and heavy metal-free formulations need to be confirmed first, but the compliance of other components such as paper/plastic substrates, coatings, adhesives, and recycled material sources must also be verified at the same time.
• High difficulty: PVC packaging, leather packaging, high-proportion recycled material packaging, and packaging with metal coatings. These materials have a relatively high probability of heavy metal exceeding the standard. You should first request targeted test reports or stronger compliance certifications, and should not release them solely based on the supplier’s verbal promises.
If your packaging is of high difficulty type, it is recommended to give priority to suppliers with experience in EU packaging compliance. Their materials and processes are more mature, which helps reduce the risks of subsequent sampling, supplementary testing, and material replacement.
3. What if it exceeds the standard?
If the test finds that it exceeds the standard, don’t panic first, and handle it according to this procedure:
First, verify first: Is the test method wrong? For example, the disassembly unit is incorrect, non-packaging components are included, or hexavalent chromium is mistakenly tested as total chromium, resulting in a high result — first rule out problems with the test itself.
If it does exceed the standard, replace it in time: for example, switch to heavy metal-free ink, replace PVC material with safer materials such as PE and PET, use higher-purity recycled materials or virgin materials, and solve the problem from the source.
If your packaging falls into the legal exemption category, organize the corresponding supporting documents, such as the compliance certificate for dangerous goods transport packaging and the exemption basis for medical device packaging, in preparation for customs or regulatory verification.
Finally, a red line reminder: never conceal the situation of exceeding the standard. Once found by EU customs or market supervision, the light consequence is cargo detention and fines, and the heavy consequence is being blacklisted and banned from entering the EU market, which is not worth the loss.
4. Key management points for long-term compliance
Compliance is not a one-time thing. To meet the requirements stably for a long time, it is enough to do these three points well:
• Supplier management: Clearly require in the procurement contract that the packaging must meet the EU packaging heavy metal limits, and at the same time agree that if the supplier changes materials or formulas, they must notify you in advance to avoid exceeding the standard without your knowledge.
• Changes trigger re-evaluation: As long as you change suppliers, packaging materials, colors, inks, or adjust the proportion of recycled materials, you must re-evaluate compliance. Don’t think that if there was no problem before, there will never be a problem.
• Document preservation: All test reports, compliance statements, supplier commitments and other documents must be properly preserved. EU market supervision and spot checks may occur at any time, as long as you can produce them when needed.
VII. Common Misunderstandings and Quick Self-Check List
Finally, we have sorted out the 6 most common pitfalls for beginners, and provided a self-check list that can be completed in 1 minute to help you quickly check your situation.
1. 6 most common misunderstandings for beginners
1. Only plastic/color packaging needs to comply? Wrong. Packaging of all materials, whether paper, glass, metal or wood, must meet the requirements, which has nothing to do with color or material.
2. 100ppm is the limit for each heavy metal? Wrong. It is the total content limit of 4 heavy metals, and the total must not exceed 100ppm to be considered up to standard.
3. RoHS/food contact/REACH reports can replace packaging heavy metal testing? Wrong. Different regulations have different regulatory logics and applicable scenarios, and cannot be used interchangeably (see Chapter IV for specific differences).
4. Ink/labels are light in weight so they don’t count? Wrong. As long as it is a component of packaging, no matter how light it is, it must be counted, and cannot be ignored because of its small weight.
5. Not detected means absolutely no heavy metals? Wrong. Not detected only means it is lower than the detection limit of the test method, and does not mean the content is 0.
6. Transport packaging/e-commerce packaging does not need to comply? Wrong. As long as the packaging is delivered to the buyer together with the goods, whether it is for transport or sales, it must comply.
2. 1-minute quick self-check list (beginner version)
You can conduct a quick initial screening against these 6 questions. If all are “yes”, it means that the beginner-level compliance framework has been initially covered, but you still need to further verify whether the test object of the test report is the smallest detachable unit, whether the report batch matches the actual goods, and whether exempt packaging has complete supporting documents, to confirm the final compliance:
• □ Will my packaging be placed on the EU/EEA/UK market?
• □ Is my packaging not in the legal exemption category?
• □ Have I disassembled the packaging into the smallest detachable units and listed all components?
• □ Is there compliance certification for high-risk materials such as color ink, PVC, leather, and recycled materials?
• □ Can I produce the test report or supplier compliance statement for the corresponding batch?
• □ Am I not using reports from other regulations to make up the number?
Summary
In general, the EU’s heavy metal restrictions on packaging seem to have many items, but the core logic is actually very clear: as long as the packaging is placed on the EU market, except for a few legally exempt situations, it must meet the requirement that the total content of the 4 heavy metals lead, cadmium, mercury, and hexavalent chromium does not exceed 100ppm, judged by the smallest detachable unit, and compliance documents of other EU environmental regulations cannot be mixed.
After reading this article, you should be able to master six core competencies: quickly judge whether this rule applies to packaging; accurately state the 4 restricted heavy metals and the 100ppm total limit requirement; distinguish between 3 types of legal exemptions and common false exemptions; clarify the boundaries between this rule and RoHS, REACH, and food contact materials regulations; complete packaging disassembly and preliminary compliance screening according to the 4-step process; verify key information of test reports, and re-evaluate compliance in a timely manner when materials, processes, or suppliers change.
