Most PCB buyers know about RoHS. But when your shipment of 10,000 assembled boards arrives at Rotterdam or Long Beach, it's REACH, WEEE, and TSCA that determine whether customs releases the container or flags it for laboratory testing — at your expense. A single non-compliant substance at 0.1% concentration can trigger a rejected shipment, a mandatory recall, or a €50,000+ fine under EU enforcement. Here's what you need to know beyond RoHS.
At Huaxing PCBA, we ship to 30+ countries and maintain full material declarations (FMD) for every laminate, solder paste, and conformal coating in our supply chain. Our IATF 16949 and ISO 14001 certifications include REACH Article 33 communication procedures — meaning we can tell you exactly which Substances of Very High Concern (SVHCs) are present in your boards, if any, before they leave our factory. Here's how the three major regulations apply to your PCB imports.
REACH: Substances of Very High Concern (SVHC) in PCB Materials
REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals) is the EU's chemical safety regulation (EC 1907/2006). Unlike RoHS — which bans six specific substances from electronic equipment — REACH covers 240+ SVHCs across all products, with new substances added to the Candidate List twice per year. For PCB importers, the key obligations are Article 33 (communication duty) and Article 7 (notification duty).
SVHCs That Appear in PCB Manufacturing
| SVHC Substance | Where It Appears in PCBs | Threshold | Status (2026) |
|---|---|---|---|
| Lead (Pb) | Solder (if non-RoHS), component terminations | 0.1% w/w | Candidate List |
| DEHP / DIBP / DBP / BBP (Phthalates) | Flex PCB coverlay adhesives, wire insulation | 0.1% w/w (sum) | Authorization List (Annex XIV) |
| Boric Acid / Borates | FR-4 flame retardant (boron-based) | 5.5% (boric acid), 3.1% (borates) | Candidate List |
| TBBPA (Tetrabromobisphenol A) | FR-4 brominated flame retardant | 0.1% w/w | Under evaluation (Restriction proposed) |
| PFAS (Per- and polyfluoroalkyl substances) | PTFE-based high-frequency laminates, non-stick mold release | 25 ppb (proposed EU-wide restriction) | Restriction dossier submitted (2023) |
| Melamine | FR-4 resin cross-linker (melamine-formaldehyde) | 0.1% w/w | Candidate List |
| Antimony Trioxide | FR-4 flame retardant synergist | 0.1% w/w | Candidate List |
Critical Update: The EU's universal PFAS restriction proposal (submitted by Germany, Netherlands, Denmark, Norway, and Sweden in January 2023) is expected to take effect in 2027–2028. This will ban PTFE-based PCB laminates — widely used in RF and high-frequency PCB designs — unless exemptions are granted. Importers of telecom and aerospace PCBs should begin qualifying hydrocarbon-ceramic laminate alternatives (Rogers RO4000-series, Isola Astra MT77) now.
Article 33: Your Duty to Communicate SVHC Information
If any article (which includes a bare PCB or assembled PCBA) contains an SVHC above 0.1% weight-by-weight, REACH Article 33 requires the supplier to provide — within 45 days of a customer request — the name of the substance and safe-use information. This obligation cascades down the supply chain: your PCB manufacturer must disclose to you, and you must disclose to your EU customer.
Request Full Material Declaration (FMD) from Your PCB Supplier
A compliant FMD lists every homogeneous material in the PCB (laminate, solder mask, surface finish, legend ink) with its chemical composition down to 0.1% by mass. Generic statements like "RoHS compliant" or "REACH compliant" are not acceptable substitutes — EU enforcement authorities require traceable documentation. See our RoHS compliance guide for what a proper material declaration looks like.
Monitor the ECHA Candidate List Twice Per Year
ECHA adds new SVHCs every January and July. A substance that was unregulated when you placed your order could be listed by the time your shipment arrives. Subscribe to ECHA's RSS feed and cross-reference new entries against your supplier's FMD within 30 days of each update. Our PCB certifications guide includes a compliance calendar template.
SCIP Database Submission (EU Waste Framework Directive)
Since January 2021, any article containing an SVHC above 0.1% must be registered in ECHA's SCIP database with a unique identifier. The importer of record (that's you, if you're the EU-based entity placing the product on the market) is responsible for this submission — your Chinese PCB supplier cannot do it for you. The database is public, and NGOs actively scan it for enforcement targets.
WEEE: Extended Producer Responsibility for PCB Assemblies
The Waste Electrical and Electronic Equipment Directive (2012/19/EU) requires producers and importers of electronic equipment to finance the collection, treatment, and recycling of their products at end-of-life. While individual PCBs may fall below the de minimis thresholds, the assembled products they go into almost certainly don't.
WEEE Categories That Apply to PCB-Based Products
Since the 2018 "open scope" revision, all electrical and electronic equipment falls under WEEE unless specifically excluded (military, space, large-scale fixed industrial tools). The six current categories most relevant to PCB importers:
Category 1: Temperature Exchange Equipment
Any PCB inside a refrigerator, air conditioner, or heat pump. These products have an 80% recovery and 75% recycling target. The metal-core PCBs used in these applications (see our MCPCB guide) must be separable from the aluminum substrate for material recovery.
Category 5: Small Equipment (external dimension ≤ 50 cm)
This is the catch-all category for most consumer, IoT, and medical devices containing PCBs. 55% recovery and 50% recycling targets. If your PCB goes into a smart home sensor, wearable device, or handheld diagnostic tool, it falls here.
Category 6: Small IT and Telecommunications Equipment
Routers, switches, base stations — anything that processes or transmits data. The PCB is the highest-value recyclable component, containing gold (edge connectors), palladium (MLCCs), and copper (inner layers). Our telecom PCB guide covers the specific laminate requirements.
Practical Impact: If you're importing PCBA-based products into the EU, you must register as a WEEE producer in each member state where you sell, report your placed-on-market weight annually, and either join a collective compliance scheme (e.g., ERP, Recolight) or set up your own take-back system. Non-compliance penalties start at €5,000 per member state and escalate to product withdrawal orders.
TSCA: US Chemical Regulation and PFAS in PCBs
The US Toxic Substances Control Act (TSCA), as amended by the 2016 Frank R. Lautenberg Chemical Safety Act, gives the EPA authority to restrict or ban chemicals that pose unreasonable risk. For PCB importers, the critical development is the EPA's October 2024 final rule on PFAS reporting under TSCA Section 8(a)(7).
TSCA Section 8(a)(7): PFAS Reporting Rules
Effective January 2026, any entity that has manufactured or imported PFAS or PFAS-containing articles since January 1, 2011 must submit a one-time report to the EPA covering:
Chemical Identity and CAS Number of Each PFAS Substance
This includes PTFE (CAS 9002-84-0), the most common high-frequency PCB laminate material. Even if the PTFE is fully polymerized (considered low-risk in its final form), the reporting obligation still applies under TSCA's broad PFAS definition — any molecule containing at least one fully fluorinated carbon atom.
Categories of Use and Volume Imported (2011–2025)
The EPA requires estimated import volumes by year, categorized by industrial sector. For PCB importers using PTFE laminates (Rogers RO3000/RT-duroid, Taconic RF-35, Arlon AD-series), the category is "Electrical and Electronic Products — Printed Circuit Boards." Even small importers qualify — there is no de minimis volume exemption.
Environmental Release and Worker Exposure Data
You must describe how the PFAS-containing PCB is processed at end-of-life (incineration, landfilling, recycling) and any known occupational exposure during PCB fabrication. This requires coordination with your PCB supplier's environmental health and safety data, which should be part of your supplier audit questionnaire.
TSCA Section 6(h): PBT Chemicals Already Restricted
Five persistent, bioaccumulative, and toxic (PBT) chemicals have been restricted since 2021. Two are directly relevant to PCB manufacturing:
Decabromodiphenyl Ether (DecaBDE) — Flame Retardant
Banned in PCB laminate production. Any FR-4 designated as "non-RoHS" or manufactured before 2021 may contain DecaBDE. Importers must verify that their supplier's laminate certification explicitly states "DecaBDE-free" — RoHS compliance alone doesn't cover this because DecaBDE was exempted from RoHS until 2019. Confirming this is part of our PCB materials qualification process.
PIP (3:1) — Plasticizer in Flex PCB Coverlay
Phenol, isopropylated phosphate (3:1) was used as a flame retardant plasticizer in polyimide coverlay films for flex and rigid-flex PCBs. It is now prohibited above 0.1% in articles. Our flex PCB manufacturing guide covers the PIP-free coverlay alternatives now used in production.
Practical Compliance Checklist for PCB Importers
Here is the step-by-step process we recommend to every customer importing PCBs into the EU or US:
Request an IPC-1752A Class D Material Declaration from Your Supplier
This is the industry-standard format for full material disclosure. It covers REACH SVHCs, RoHS substances, and can be extended to TSCA PBTs. Any competent PCB manufacturer serving export markets should be able to provide this within one business week. If they can't, that's a red flag. Use our IPC standards comparison guide to understand the Class levels.
Cross-Reference Laminate Datasheets Against ECHA Candidate List
Your supplier's FMD is only as good as their upstream laminate data. Request the manufacturer datasheet for your specific laminate grade (e.g., Shengyi S1000-2M, ITEQ IT-158, EMC EM-827) and verify the flame retardant chemistry. If the datasheet says "brominated epoxy" without specifying the exact compound, ask for clarification — it could be TBBPA (under evaluation) or DecaBDE (already banned).
Register for WEEE in Each EU Member State Where You Sell
Use a pan-European compliance scheme like ERP or Landbell Group to handle multi-country registration. Budget €500–1,500 per member state per year, depending on your placed-on-market weight. Your PCB's weight alone may not trigger an obligation, but the finished product it goes into almost certainly will. If you're unsure about your PCB's classification, our import duty and tariff guide includes customs classification codes.
Prepare TSCA PFAS Report If You Imported PTFE Laminates (2011-2025)
The one-time reporting window extends through mid-2026. If your PCB uses PTFE-based materials (Rogers, Taconic, Arlon), start gathering import volume data now. The EPA's electronic reporting tool (CDX) accepts bulk submissions — your customs broker or freight forwarder can extract the relevant HS code data from past entries.
Include Compliance in Your Supplier Audit
REACH and TSCA compliance isn't a one-time certification — it's a continuous process that must be verified during supplier audits. Add these questions to your next audit: (1) How often do you update your FMD to reflect new ECHA Candidate List additions? (2) Can you provide laminate lot-level traceability to the chemical composition? (3) What is your process for customer notification when an SVHC is newly listed? Our PCB supplier audit checklist includes a full environmental compliance module.
At Huaxing PCBA, REACH and RoHS compliance is not an add-on — it's embedded in our material procurement process. Every laminate batch is qualified against the latest ECHA Candidate List before entering production. We provide IPC-1752A Class D declarations as standard documentation with every shipment, and our ISO 14001-certified environmental management system tracks substance restrictions across our full laminate portfolio. Before you place your next PCB order in China, ask for the material declaration — and if the answer is "we comply with RoHS," dig deeper. The three regulations above apply whether your supplier acknowledges them or not.
