Adhesive tapes rarely appear on a bill of materials as a critical component, yet they ship inside almost every electronic, automotive, and appliance assembly. A polyimide tape masking a PCB during wave soldering, a double-sided PET tape bonding a display module, or an insulation tape wrapping a transformer all become part of the finished product. If any of them contains a restricted substance, the entire product can fail import inspection in the EU and similar markets that mirror EU rules.
For procurement engineers and distributors, the practical risk is not usually the polymer film itself—PET, polyimide, and PTFE backings are generally low-risk—but the adhesive system, plasticizers, flame retardants, pigments, and release liners. These are exactly the layers where legacy formulations historically used phthalates, brominated flame retardants, or heavy-metal stabilizers. Compliance therefore has to be verified per product and per formulation, not assumed from the backing material.
The EU RoHS Directive (2011/65/EU, commonly called RoHS 2, with the 2015/863 amendment sometimes labeled RoHS 3) restricts ten substances in electrical and electronic equipment: lead, mercury, cadmium, hexavalent chromium, two brominated flame retardant families (PBB and PBDE), and four phthalate plasticizers (DEHP, BBP, DBP, DIBP). The regulatory limit is 0.1% by weight per homogeneous material, except cadmium at 0.01%. Crucially, a tape is not one homogeneous material—the backing, adhesive, and any primer or liner are each evaluated separately.
In tape products, the substances most worth scrutinizing are phthalates in soft PVC backings and some rubber adhesives, cadmium or lead compounds in older pigment and stabilizer systems, and brominated compounds in flame-retardant grades. Tapes built on PET, polyimide, copper, or aluminum foil with acrylic or silicone adhesives are typically straightforward to formulate RoHS-compliant, which is one reason electronics assemblers favor them. The differences between adhesive chemistries are covered in more depth in our guide to acrylic vs rubber adhesives.
REACH (EC 1907/2006) works differently from RoHS. Rather than banning a fixed list outright, it maintains a Candidate List of Substances of Very High Concern (SVHC), updated roughly twice a year by ECHA and now containing well over 200 entries. For articles such as adhesive tapes, the key obligation is Article 33: if any SVHC is present above 0.1% by weight of the article, the supplier must inform the customer and provide safe-use information. EU suppliers must also file SCIP database notifications for such articles.
For buyers, the practical takeaway is that a REACH statement is a declaration, not a certificate. Because the Candidate List changes every January and June or July, an SVHC declaration referencing a list version from two years ago provides weak assurance. A competent supplier statement should name the Candidate List version or date it was assessed against, state whether any SVHC exceeds 0.1% w/w, and be reissued when the list updates or the formulation changes.
A credible compliance file for an industrial tape typically contains four elements. First, a Declaration of Conformity (DoC) issued by the manufacturer, identifying the exact product code, the directives or regulations covered (RoHS 2011/65/EU as amended, REACH SVHC), and a responsible signatory. Second, third-party test reports from laboratories such as SGS, Intertek, or TÜV showing screening results for the RoHS substances—reputable reports list each restricted substance with a detection limit and result, and they identify which layer of the tape was tested. Third, an SVHC assessment letter referencing a current Candidate List version. Fourth, where relevant, halogen content data (see below).
Check the details, not just the logo. Test reports should be recent—many OEMs require reissue every one to three years or after any formulation change—and the sample description should match the product you are buying, including color and adhesive type, since pigments alone can change the result. For tapes performing a measurable function, buyers often pair the compliance file with performance data such as peel adhesion tested to ASTM D3330, so that compliance and mechanical specification are reviewed together. Selection criteria for heat-resistant grades are summarized in how to choose high-temperature tape.
Beyond legal minimums, much of the electronics supply chain—particularly PCB, battery, and consumer-device manufacturers—now specifies halogen-free materials. The most cited benchmark is IEC 61249-2-21, which defines halogen-free as chlorine below 900 ppm, bromine below 900 ppm, and total halogens below 1500 ppm. This is a customer-driven specification rather than a law, but for tapes used in PCB masking, battery insulation, or EMI shielding it is increasingly treated as a de facto requirement.
Halogen-free demand affects tape selection directly. Standard PVC masking tapes are chlorinated by nature and cannot meet the threshold, which pushes electronics users toward crepe paper, PET, or polyimide constructions. Flame-retardant tapes need phosphorus- or nitrogen-based systems instead of brominated additives. Conductive products such as copper foil tape and ESD tapes for static-sensitive assembly are likewise routinely ordered with halogen test reports. If your end customer is in consumer electronics or EV batteries, ask for halogen data up front rather than discovering the requirement at audit.
HONGFU manufactures industrial tapes factory-direct across 59 categories—including high-temperature tapes, polyimide (Kapton-type) tape, double-sided tapes, foil, ESD, and insulation products—with RoHS and REACH documentation available for compliant grades, plus die-cutting services for converted parts. Send your application details and compliance requirements through our inquiry page to receive datasheets, declarations, and samples for evaluation.
RoHS applies to electrical and electronic equipment sold in the EU, so a tape must comply when it ships inside such a product. Tapes for packaging or general industrial use fall outside RoHS scope, but many buyers specify RoHS-compliant grades anyway to keep one approved inventory across applications.
There is no official "RoHS certificate." Compliance rests on the manufacturer's Declaration of Conformity, which is a self-declaration. A third-party test report from a lab such as SGS or Intertek provides supporting evidence for a specific sample and date. Strong compliance files include both, with the report matching the exact product code.
The ECHA Candidate List is updated roughly twice a year, typically in January and June or July. A declaration should reference the list version it was assessed against and be reissued after each update or whenever the tape formulation changes. Many OEMs reject SVHC letters older than about twelve months.
No. RoHS restricts specific brominated flame retardants (PBB, PBDE) but does not limit total halogen content. Halogen-free is a stricter customer specification, commonly based on IEC 61249-2-21: under 900 ppm chlorine, under 900 ppm bromine, and under 1500 ppm total. A PVC tape can be RoHS compliant yet never halogen-free.
The highest-risk layers are soft PVC backings (phthalate plasticizers), flame-retardant additives (brominated compounds), pigments and stabilizers (lead, cadmium), and some rubber adhesive systems. PET, polyimide, and foil backings with acrylic or silicone adhesives are generally lower risk, but each homogeneous layer still requires verification.
