Heavy metals can be found in everything from jewelry and watch cases to electronic components and toy paints. While lead, cadmium, mercury, and other heavy metals serve a purpose – these substances are also strictly regulated in the European Union.
Keep reading, and learn what you must know about EU heavy metals regulations, including REACH, RoHS, and much more.
Content Overview
What is considered a heavy metal?
Heavy metals are generally defined as metals with relatively high densities, high atomic weight, or high atomic number. The definition of heavy metals is not always fixed and might change depending on the context and subjects.
Various kinds of heavy metals and their compounds can be found in petroleum products, which constitutes a wide range of consumer products like cosmetics, personal care products, food contact products, medical devices, and electronics.
Heavy metals, such as lead, are also used in paints, dyes, and inks, in order to accelerate drying, increase durability, to delay corrosion. Finally, heavy metals might already exist in the raw materials used to manufacture the products.
Here is a list of some of the most common and regulated heavy metals:
- Lead
- Mercury
- Nickel
- Chromium
- Arsenic
Are heavy metals banned in the European Union?
Heavy metals are not completely banned in the European Union. However, they are restricted as exposure to heavy metals is proven to cause various diseases and dysfunctionalities in the human body.
For example, long-term exposure to lead might cause learning, language, and behavioral problems to young infants and children. Mercury is linked to the nervous system, reproductive, immune, and respiratory toxicity. Chromium is linked to asthma, chronic bronchitis, rhinitis, congestion, and hyperemia.
The EU and the individual member states have regulations restricting the content concentration of certain types of heavy metals in some consumer products, including:
- REACH
- RoHS Directive
- Toy Safety Directive
- Regulation (EC) 1223/2009 on Cosmetics Products
- Regulation (EC) 1935/2004 on Food Contact Materials
Which products and materials may contain heavy metals?
It’s fair to say that almost any product can contain heavy metals because they can be found in paints, metal alloys, or petroleum-based products. Paint can be applied to any material so it’s a risk that spans all products.

Heavy Metal Product Regulations Overview
REACH
REACH establishes maximum concentration limits for heavy metals, and other dangerous substances such as Phthalates or Bisphenol A, in consumer products. The restricted heavy metals are recorded in the Annex XVII of the regulation.
The specific concentration value heavy metals allowed might vary according to the product and the heavy metal that we take under consideration. For example, an amendment of REACH’s Annex XVII requires that the concentration limit for textiles, clothing, and footwear should be less than 1mg/kg – for the following substances:
- Lead and its compounds
- Cadmium and its compounds
- Chromium VI
- Arsenic
However, for jewelry products like bracelets, necklaces, watches, and rings, the concentration of lead should not be greater than 0.05 % by weight.
Below we list some of the most common heavy metals regulated by REACH, which might be found in medical devices, jewelry, textiles, cosmetics, electronics, food contact products, and other types of consumer products.
Mercury
REACH forbids the use of mercury in fever thermometers, manometers, barometers, sphygmomanometers, and thermometers.
Nickel
REACH regulates the nickel migration levels of jewelry products and accessories such as:
- Earrings
- Necklaces
- Bracelets
- Anklets
- Rings,
- Wrist-watch cases, watch straps and tighteners
- Rivet buttons

- Metal marks
The migration level of nickel for parts like pins, needles, or parts that will pierce through the body should be less than 0.2 μg/cm2/week. Parts that are designed to come into direct or indirect contact with the body should have a migration rate of fewer than 0.5 μg/cm2/week.
Cadmium
REACH prohibits the use of cadmium in amounts equal to or greater than 0.01% by weight in synthetic organic polymers, including the following ones:
- PVC
- PP
- Polyurethane
- High-impact polystyrene
- Epoxy resins
Chromium
REACH requires that Chromium VI Compounds used in leathery products like boots, purses, textiles should not exceed 3 mg/kg.
Antimony
REACH requires that the migration limit of Antimony from PET bottles and other food packagings should not exceed 40 mg/kg.
RoHS Directive
The RoHS Directive establishes rules on the restriction of the use of hazardous substances, including heavy metals, in electrical and electronic equipment (EEE) manufactured, or imported on the market of the European Union, in an effort to protect public health and the environment.
The RoHS Directive requires the maximum tolerable value of 4 kinds of heavy metals used in EEE to be 0.1%:
- Lead

All toys or components of toys regulated by this directive should not exceed the migration limits, which are different depending on the heavy metal taken into consideration.
Materials
The Toy Safety Directive differentiates the materials and textures of the toys into three types, and the tolerable limit for each type of the restricted heavy metal differs according to the material type:
a. Dry, brittle, powder-like, or pliable toy material, such as crayons
b. Liquid or sticky toy material, such a finger paint
c. Scraped-off toy material, such as metals, and coatings

Packaging: Directive 94/62/EC
The Directive 94/62/EC aims to harmonize regulations among the member states in regard to the issue of product packaging and packaging waste. This Directive prioritizes the prevention of packaging waste increases the recycling rate and reduces the final disposal of such waste.
In addition, this Directive also concerns the packaging safety to humans and the environment by limiting the sum of heavy metal concentration levels.
Specifically, the total concentration of lead, cadmium, mercury, and hexavalent chromium in product packaging should not exceed 100 ppm by weight.
Heavy Metal National Regulations
Several member states of the European Union published their own national regulations concerning the issue of heavy metal migration rates on food contact materials. We selected several countries below and briefly introduced some of their specific heavy metal restrictions.
France
The French General Directorate for Competition Policy, Consumer Affairs and Fraud Control (DGCCRF) published several documents regulating the safety of food contact products made from metals, rubbers, plastic glass, ceramic, plant fibers, and several other kinds of organic or inorganic materials.
The document DM/4B/COM/002 set up the heavy metal migration rules for FCMs that are made of inorganic materials such as ceramics, glass, glass-ceramic, and enamel as following:
- Aluminum < 1 mg/kg
- Cobalt < 0.02 mg/kg
- Arsenic < 0.002 mg/kg
Italy
The Decree of the Ministery for Health of March 21, 1973, of Italy oversees the issue of hygiene for packaging, containers, and utensils intended to come into contact with foodstuffs or personal use products.
This Decree regulates the following list of heavy metals elements contained by stainless steel food contact products:
- Chromium
- Cooper
- Nickel
- Titanium
The Netherlands
The Packagings, Paper, and Card Management Decree of the Netherlands requires that the heavy metals content in packaging and packaging components that are made from paper and card, may not exceed 100 ppm by weight. This Decree also regulates packaging for foodstuff and beverages.
These heavy metals stipulated by this Decree include:
- Lead
- Cadmium
- Mercury
- Chromium VI
Belgium
The Belgium Royal Decree of 25th September 2016 establishes a migration limit from varnishes and coatings intended to come into contact with foodstuffs.
The Decree requires the migration limit for 4 categories of food contact materials and they are plastic, ceramics, regenerated cellulose, and active and intelligent materials. The varnish and coatings migration limit of these products shall not exceed 10 mg per decimeter squared.
Spain
The Royal Decree 847/2011 of Spain establishes the positive list of substances allowed for the manufacture of polymeric materials intended to come into contact with food.
This royal decree aligns with the European Resolution AP (89) 1, which regulates the colorants in plastic materials and its heavy metal migration limit as follows:
- Lead: 0.01%
- Mercury: 0.005%
- Cadmium:0.01%
- Chromium :0.1%
- Antimony: 0.05%
- Arsenic: 0.01%
- Barium:0.01%
- Selenium:0.01%
Lab Testing
In order to confirm whether the imported products contain excessive amounts of restricted heavy metals by different legislations for different consumer products, importers can consult a lab testing company such as:
- TÜV SÜD
- Intertek
- SGS
- Eurofins
- ATS
Lab testing costs for heavy metals migration levels usually start at around US$80-100. However, they might vary according to the materials.
Strictly speaking, only lead, cadmium,mercury, barium and tin are usually considered as heavy metals. Antimony, arsenic selenium are metalloids. Titanium, chromium, manganese,cobalt, nickel, copper and zinc are first row transition metals and are found either side of iron, a very important metal for mammalian life. The difference between Cr III and Cr VI is that the latter has been found to be carcinogenic, but not the former(?) This comment is in response to Fredrik’s hesitancy with regard to what constitutes a heavy metal. I hope this is of help
Thank you John!
As a guitarist, I noted that the items quoted, with limits on nickel, do not include guitar strings; many of which have nickel coated windings around steel cores. A good review, thank you.
