Every year, procurement managers ask the same question: "Are your brass fittings RoHS compliant?" The honest answer is: it depends on which alloy, which application, and when you're asking. This guide gives you the complete, verifiable picture — not a checkbox answer that falls apart the moment someone looks closely at it.

What RoHS Actually Is
RoHS stands for Restriction of Hazardous Substances. The current directive is EU Directive 2011/65/EU (RoHS 2), amended by Commission Delegated Directive 2015/863 (RoHS 3). The directive restricts specific hazardous substances in electrical and electronic equipment (EEE) placed on the EU market.
RoHS was first adopted as Directive 2002/95/EC (RoHS 1) and came into force in July 2006. It was recast in 2011 as Directive 2011/65/EU (RoHS 2) to expand scope, introduce CE marking obligations, and provide a clearer legal framework. RoHS 3 (2015/863) added four phthalates to the restricted substances list, effective from July 2019 for most categories.
The directive is enforced by EU member state market surveillance authorities. In Germany, this is the Federal Institute for Occupational Safety and Health (BAuA). In the UK (post-Brexit), enforcement falls to Trading Standards. Penalties vary by country but can include product recalls, import bans, and significant fines.
The 10 Restricted Substances
RoHS restricts ten substances to maximum concentration values (MCVs) in homogeneous materials within EEE products. The first six have been restricted since 2006 (RoHS 1). Four phthalates were added by RoHS 3, effective from July 2019 for most product categories.
| # | Substance | Symbol / Abbr. | Max Concentration (homogeneous material) | Relevant to Brass? | Added |
|---|---|---|---|---|---|
| 1 | Lead | Pb | 0.1% (1,000 ppm) | ⚠️ Yes — see Exemption 6(c) | RoHS 1 |
| 2 | Mercury | Hg | 0.1% (1,000 ppm) | ✅ Not present in brass | RoHS 1 |
| 3 | Cadmium | Cd | 0.01% (100 ppm) | ✅ Trace only — below limit in standard alloys | RoHS 1 |
| 4 | Hexavalent Chromium | Cr⁶⁺ | 0.1% (1,000 ppm) | ✅ Not present in brass alloys | RoHS 1 |
| 5 | Polybrominated Biphenyls | PBB | 0.1% (1,000 ppm) | ✅ Not present in metals | RoHS 1 |
| 6 | Polybrominated Diphenyl Ethers | PBDE | 0.1% (1,000 ppm) | ✅ Not present in metals | RoHS 1 |
| 7 | Bis(2-ethylhexyl) phthalate | DEHP | 0.1% (1,000 ppm) | ✅ Not in solid brass (polymer/gasket concern) | RoHS 3 |
| 8 | Butyl benzyl phthalate | BBP | 0.1% (1,000 ppm) | ✅ Not in solid brass | RoHS 3 |
| 9 | Dibutyl phthalate | DBP | 0.1% (1,000 ppm) | ✅ Not in solid brass | RoHS 3 |
| 10 | Diisobutyl phthalate | DIBP | 0.1% (1,000 ppm) | ✅ Not in solid brass | RoHS 3 |
For solid brass and copper alloys, the only substance of concern is Lead (substance #1). Substances 4–10 are either not present in metallic alloys or exist only at trace concentrations well below any threshold. Cadmium (substance #3) may appear in trace quantities in some copper alloys but standard EN-specified alloys are below the 100 ppm limit.
Does RoHS Apply to Your Brass Fittings?
This is the question most suppliers dodge with a generic "yes, compliant" answer. The honest answer requires understanding scope first.
RoHS applies to Electrical and Electronic Equipment (EEE) — specifically products that depend on electric current or electromagnetic fields to work, or that generate, transfer, or measure electric current or fields, which are designed for use with a voltage rating not exceeding 1,000 V for alternating current and 1,500 V for direct current.
- 1. Large household appliances 2. Small household appliances
- 3. IT and telecommunications equipment 4. Consumer equipment
- 5. Lighting equipment 6. Electrical and electronic tools
- 7. Toys, leisure and sports equipment 8. Medical devices
- 9. Monitoring and control instruments 10. Automatic dispensers
- 11. Other EEE not covered by categories 1–10
Excluded from RoHS scope: Plumbing, gas distribution, HVAC, industrial fluid systems, automotive components (covered by End-of-Life Vehicles Directive 2000/53/EC instead), aerospace, large-scale stationary industrial tools, large-scale fixed infrastructure, means of transport for persons or goods.
| Application | In RoHS Scope? | RoHS Document Needed? |
|---|---|---|
| Plumbing fitting in domestic water system | NO | No — but buyers may request as policy |
| HVAC component in heating system | NO | No |
| Gas valve body in distribution line | NO | No |
| Industrial fluid control fitting | NO | No |
| Brass terminal block in control panel (EEE) | YES | Yes — Exemption 6(c) applies |
| Brass connector in electronic assembly | YES | Yes — Exemption 6(c) applies |
| Brass fitting in medical gas system (clinical) | YES (Category 8) | Yes — Annex IV exemptions may apply |
| Automotive brass fitting (in vehicle) | NO — ELV Directive | ELV compliance instead |
Why Lead Is in Brass at All
Pure copper-zinc brass is technically machinable, but slowly and with tool wear that makes high-volume CNC production economically unviable. Lead — typically 1.5% to 3.5% by weight — acts as an internal lubricant and chip-breaker. When a cutting tool shears through leaded brass, the lead particles cause the swarf to break cleanly rather than forming long stringy chips that damage tooling and jam machines.
The result: leaded brass machines 3–5× faster than lead-free alternatives, with dramatically better surface finish and longer tool life. For precision components — valve bodies, fittings, connectors — this translates directly into unit economics that determine whether a product is commercially viable. The entire Jamnagar brass industry, the world's largest brass component cluster, is built on this metallurgical reality.
Switching to lead-free brass is not a simple substitution. It requires reformulating alloys (silicon brass, bismuth brass, tellurium copper), recalibrating CNC programs for different chip formation behaviour, extending cycle times by 30–80%, and requalifying tooling. For many precision fittings — particularly those with thin walls, complex internal geometries or fine thread pitches — lead-free alternatives produce acceptable quality at unacceptable cost. The EU legislators understood this in 2002. Hence Exemption 6(c).
Exemption 6(c): The Brass Exemption in Full
Annex III of RoHS Directive 2011/65/EU lists exemptions from the substance restriction requirements. Exemption 6(c) states:
"Lead in copper alloy containing up to 4% lead by weight"
Source: EUR-Lex — Directive 2011/65/EU, Annex III · Also see Amending Directive 2015/863
This is an Annex III exemption — meaning it applies across all EEE product categories without restriction. It is not category-specific (unlike Annex IV exemptions for medical devices). Any copper alloy, including all brass grades (Cu-Zn), bronze (Cu-Sn), and gunmetal (Cu-Sn-Zn-Pb), containing up to 4% lead by weight is exempt from the general 0.1% lead restriction when used in EEE.
Exemption 6(c) — Renewal History
| Period | Status | Legal basis |
|---|---|---|
| 2002–2006 | In force (RoHS 1) | Directive 2002/95/EC, Annex — included from original adoption |
| 2006–2013 | In force (RoHS 1) | Continuous — no expiry date in original directive |
| 2013–2021 | In force (RoHS 2) | 2011/65/EU Annex III — renewed periodically per Art. 5(2) |
| July 2021 | Interim extension | Pending renewal application — Commission extended on interim basis |
| November 2025 | Formally renewed | EU Commission Delegated Directive extending to 30 June 2027 |
| 30 June 2027 | Current expiry | Renewal application submitted December 2025 — decision pending |
If Exemption 6(c) is not renewed beyond 30 June 2027, standard leaded brass (CW617N, ~2% Pb) would be non-compliant for EEE applications under EU RoHS. The general 0.1% lead limit would apply without exception.
Industry bodies — including Eurofer, CECOF, and the European Copper Institute — have argued that technically and economically equivalent lead-free alternatives are not yet available across all brass fitting applications. The Commission evaluates exemption renewals based on criteria in Article 5(1)(a): whether elimination of lead is "scientifically or technically impracticable", and whether the "reliability of substitutes is not ensured". The exemption has been renewed at every previous expiry. The outcome of the post-2027 renewal application was pending at time of writing (May 2026).
If your application requires post-2027 certainty today: CW724R silicon brass (<0.09% Pb) is the only grade below the 0.1% general limit — it needs no exemption and remains compliant regardless of Exemption 6(c) renewal. CW602N DZR (0.2–0.3% Pb) reduces lead content but still exceeds the 0.1% limit and still depends on Exemption 6(c).
Alloy Comparison: CW617N, CW602N, CW614N, and Lead-Free Options
Not all brass is the same. Here is a full comparison of the most common brass and copper alloys used in fittings, showing their RoHS status and practical trade-offs.
| Alloy | Standard | Lead % | RoHS Status (EEE) | Machinability | Best For |
|---|---|---|---|---|---|
| CW617N (Free-machining brass) | EN 12164 | 1.6–2.5% | Exempt 6(c) to Jun 2027 | Excellent (100) | Standard fittings, valves, connectors |
| CW614N (High-tensile brass) | EN 12164 | 2.5–3.5% | Exempt 6(c) to Jun 2027 | Excellent (95) | High-pressure, structural fittings |
| CW602N (DZR low-lead) | EN 12164 | 0.2–0.3% | Exempt 6(c) to Jun 2027 — still exceeds 0.1% limit | Good (70) | Potable water (WRAS), chlorinated water, DZR applications |
| CW724R (Silicon brass) | EN 12165 | <0.09% | General limit — no exemption | Good (65) | Lead-free EEE, drinking water (no Prop 65 warning) |
| CW510L (Phosphor bronze) | EN 12163 | <0.05% | General limit — no exemption | Moderate (50) | Springs, contacts — not typical for fittings |

Homogeneous Material: What It Means for Testing
RoHS concentration limits apply to homogeneous materials — not to the finished product as a whole. This is a critical concept often misunderstood by non-specialist procurement teams.
A "homogeneous material" is a material of uniform composition throughout — one that cannot be mechanically disjointed into different materials. For a solid brass fitting, the homogeneous material is the brass alloy itself. The maximum concentration values apply to this material in isolation. So a CW617N brass body with ~2% lead is assessed against the 0.1% lead limit as a homogeneous material — and it fails, which is precisely why Exemption 6(c) exists.
Where this matters practically: if a brass fitting assembly includes a rubber gasket, a nickel-plated surface, or a polymer cap, each of those is a separate homogeneous material assessed independently. The rubber gasket might contain DEHP (phthalate); the plating might contain cadmium. Each must be assessed separately. An EEE manufacturer incorporating brass fittings into a final product must assess the RoHS status of each homogeneous material, not just the brass.
How RoHS Is Tested: XRF, ICP-MS, and Material Certificates
RoHS compliance for metal components is verified by chemical analysis. The two primary methods are:
X-Ray Fluorescence (XRF) — Primary Screening Method
XRF is a non-destructive analytical technique that bombards a sample with X-rays and measures the characteristic fluorescence emitted by each element. It can identify and quantify elements present in a few seconds without damaging the component. XRF is accurate to approximately ±50–200 ppm for most elements, which is sufficient for the 1,000 ppm (0.1%) and 100 ppm (0.01% cadmium) limits. XRF is used for incoming inspection and production monitoring. Most large EEE manufacturers and independent labs offer XRF screening. Portable XRF analyzers (e.g., Olympus Vanta, Bruker S1 TITAN) are widely used for on-site verification.
ICP-MS / ICP-OES — Confirmatory Method
Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Optical Emission Spectrometry (ICP-OES) provides higher precision analysis — accurate to single-digit ppm levels. It requires sample dissolution, is destructive, and takes longer, but is used for official regulatory verification, dispute resolution, and when XRF results are inconclusive or close to a threshold. Third-party labs accredited to ISO/IEC 17025 perform ICP analysis for RoHS compliance.
Material Test Certificates (MTC)
All Brassland shipments are accompanied by Mill Test Certificates / Material Test Reports (MTR) showing the chemical composition of the alloy batch. These are issued by our in-house spectrometer and confirmed against EN 12164/12165 alloy specifications. MTCs provide the primary documentary evidence of alloy composition for RoHS compliance purposes.
- RoHS Declaration of Conformity (specifying applicable exemptions)
- Material Test Certificate / Mill Certificate for each alloy/batch
- EN alloy specification for the grade supplied (e.g. EN 12164 CW617N)
- XRF or ICP test report if required by your quality system
The RoHS Regulatory Timeline for Brass
UK RoHS Post-Brexit
Following the UK's departure from the EU, the UK adopted its own RoHS legislation: The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012 (SI 2012/3032), as amended by The RoHS Regulations 2019 (SI 2019/492). This regulation is commonly called "UK RoHS".
UK RoHS mirrors EU RoHS in all material respects: the same 10 restricted substances with the same maximum concentration values, the same product categories, and the same exemption structure including Exemption 6(c) for copper alloys. However, UK RoHS is now a separate legal instrument — compliance with EU RoHS does not automatically confer UK RoHS compliance, and vice versa. Manufacturers supplying both EU and UK markets must document compliance against both frameworks.
UK enforcement is by Trading Standards authorities. Products for the UK market require UKCA marking (replacing CE marking) where applicable. Brassland RoHS compliance statements are issued to cover both EU Directive 2011/65/EU and UK SI 2012/3032 (as amended).
Global RoHS Equivalents
The EU's RoHS Directive has been widely adopted or adapted globally. If you export to multiple markets, you may need to comply with several parallel frameworks:
The USA has no federal RoHS equivalent. California's Proposition 65 addresses toxic chemicals in consumer products but differently (warning-based, not restriction-based). The EU RoHS directive does not apply to products sold only in the US market. However, many US OEMs require EU RoHS compliance as a supply chain policy standard regardless of their end market. See our California Prop 65 guide for the US regulatory framework.
What a RoHS Compliance Statement Actually Means
A RoHS compliance certificate or declaration of conformity from a brass fitting manufacturer does not mean the product contains zero lead or zero restricted substances. It means one of two things: either the product contains all restricted substances below their maximum concentration values in every homogeneous material, or any substance exceeding the limit is covered by a valid Annex III or Annex IV exemption.
When Brassland issues a RoHS compliance statement for standard brass fittings, that statement confirms compliance under Exemption 6(c) for lead content. It does not claim zero lead. The declaration will explicitly state the exemption relied upon.
A common problem in supply chains is generic "RoHS compliant" declarations that do not identify which exemptions apply. If your auditor or customer asks about this, the right response from any brass supplier is: "compliant under Annex III Exemption 6(c), valid until 30 June 2027, lead content [X]% by alloy specification EN 12164 CW617N".
How to Verify a Supplier's RoHS Claim
Not all RoHS declarations are equal. Here is what to check when evaluating a brass supplier's compliance documentation:
| What to check | What good looks like | Red flag |
|---|---|---|
| Exemption cited | States "Exemption 6(c), Annex III, Directive 2011/65/EU" | No exemption mentioned, or generic "RoHS compliant" |
| Alloy identification | Names alloy (e.g. CW617N) and EN standard | Only says "brass" with no alloy specification |
| Lead content | States actual Pb% range from alloy spec (e.g. 1.6–2.5%) | Claims 0% lead for leaded brass — false |
| Validity date | Acknowledges exemption valid to 30 June 2027 | No expiry date mentioned |
| Supporting test | Provides MTC, XRF report or ICP certificate | Declaration only, no supporting analytical evidence |
| Scope statement | Clarifies whether plumbing use is in or out of RoHS scope | Implies RoHS applies to all brass regardless of application |
| Signatory | Signed by authorised representative with title and date | Unsigned, undated, or created by supplier's junior sales team |
Brassland's RoHS Position — Summary
- CW617N standard fittings: RoHS-compliant under Exemption 6(c), Annex III, Directive 2011/65/EU for EEE applications. Valid to 30 June 2027. Lead content 1.6–2.5% per EN 12164.
- CW602N DZR fittings: RoHS-compliant under Exemption 6(c). Lead content 0.2–0.3% per EN 12164. Note: 0.2–0.3% Pb still exceeds the 0.1% RoHS general limit — CW602N also relies on Exemption 6(c), the same as CW617N. Preferred for potable water (WRAS/DZR) applications.
- CW614N high-tensile fittings: RoHS-compliant under Exemption 6(c). Lead content 2.5–3.5% per EN 12164.
- Plumbing / gas / HVAC / industrial: RoHS not applicable — these applications are outside EEE scope. RoHS documentation can be provided on request as a supply chain policy document.
- Documentation: Full RoHS Declaration of Conformity (EU and UK) issued at order confirmation. Material Test Certificates supplied as standard with all shipments. XRF test reports available on request.
