A REACH SVHC declaration, a conflict-minerals statement and a full material disclosure are documents your EU customer or customs broker will demand before nickel alloy lands in Europe, but most suppliers hand you a generic form that does not describe the heat you bought. This guide shows how to demand one tied to your melt and verify it.
Short answer: a REACH SVHC declaration, a conflict-minerals statement and a full material disclosure are documents your EU customer or customs broker will demand before nickel alloy lands in Europe — but most suppliers hand you a generic form that does not describe the actual heat you bought. This guide shows how to demand a declaration tied to your specific melt, how to verify it against the chemistry on the mill certificate, and the purchase-order clauses that turn a false declaration into the seller's liability rather than yours.
Nickel-based and high-temperature alloys are sold on chemistry. The same grade from two different melt routes can carry different residual elements, different cobalt origin and different trace substances — and those differences are exactly what REACH, the EU Conflict Minerals Regulation and your customer's own compliance program ask about. A declaration that merely names the grade is worthless; a declaration that names the heat number and the actual composition is what clears customs and satisfies an auditor.
We write this from the mill side. At Hangbo we melt every heat from 100% virgin prime charge, remelt by VIM plus ESR or VIM plus VAR, fully remove oxide scale before working, and hold each heat to its specified solution-anneal or age treatment, so the chemistry on the certificate is the chemistry in the bar — and the declaration we issue names that exact heat number.
Short answer: REACH and the Conflict Minerals Regulation are written around the actual substance present in the article, not the grade name, so a boilerplate form that only says "Inconel 625" cannot show compliance and will be rejected at the border or by your customer's QA.
Under REACH (Regulation (EC) No 1907/2006), any article containing more than 0.1% w/w of a substance on the SVHC (substances of very high concern) candidate list must be communicated down the supply chain, including the identity of the substance and safe-use information. Nickel and several nickel compounds sit on that list. The Conflict Minerals Regulation ((EU) 2017/821) obliges importers of certain products to report due diligence on tin, tungsten, tantalum and gold (the 3TG metals) that may originate from conflict-affected areas.
The trap is structural. A trading company rarely owns the melt. It forwards a declaration it copied from a previous order, or a generic template downloaded from the internet, and hopes you never check. A mill that actually poured the heat can issue a declaration that references the same heat number as the certificate, lists the real cobalt and tantalum sources, and stands behind it. If your declaration names the wrong chemistry, the liability for a non-compliant import sits with the importer — you.
This matters most for buyers choosing between nickel alloy and stainless steel, because the two material families trigger very different declaration obligations, and for anyone shipping into chemical or energy service where a customer already runs a strict supplier-compliance portal.
Short answer: most declaration problems fall into five patterns — wrong heat, boilerplate text, missing cobalt or tantalum origin, no SVHC statement, and a form with no accountable signatory.
| Problem | Root cause | Symptom you see | How to detect it | How to prevent it |
|---|---|---|---|---|
| Declaration names a grade, not a heat | Seller copied a template; never tied paper to your melt | Heat number on declaration does not match the MTC | Cross-check the declaration's heat number against the EN 10204 certificate | Require the declaration to cite the exact heat number in the PO |
| Boilerplate SVHC text | Generic "compliant with REACH" sentence | No named SVHC, no concentration, no safe-use note | Read for a specific substance identity and a measured or calculated % | Require an article-14-style communication naming any SVHC > 0.1% |
| No cobalt or tantalum origin | Alloy contains Co/Ta but the 3TG step was skipped | Declaration silent on conflict minerals | Ask for the smelter names and country of origin for Co and Ta | Require a conflict-minerals statement per (EU) 2017/821 |
| Chemistry does not match the bar | Declaration lifted from a different grade | Listed elements differ from the MTC composition | Compare declaration composition to the certified chemistry | Buy only where the mill issues both from the same heat |
| No accountable signatory | Anonymous PDF with no letterhead | No company name, no signature, no date | Check for a named contact and company on letterhead | Reject unsigned declarations; require mill letterhead |
Short answer: the substance you must disclose is usually nickel itself (and certain nickel compounds), plus any SVHC present above the 0.1% threshold from residuals, coatings or filler additions.
Nickel metal and nickel compounds are listed as SVHC for their carcinogenicity and sensitising properties. For solid nickel alloy bar, tube, plate and forgings, the communication is normally about the alloy as an article: you state whether any SVHC is present above 0.1% w/w and, if so, provide the substance name and safe-use guidance. Residuals are the part buyers forget — a grade with deliberately added cobalt (many superalloys) or trace tantalum can trip the threshold through the alloy design itself, not through contamination.
Where the part is welded, the filler also matters. A 625 filler such as ERNiCrMo-3 carries its own chemistry that must be consistent with the declaration, and a Monel 400 or Nickel 200 component brings different residuals into play. The safe practice is to declare per heat for the base metal and per batch for any weld consumable, and to keep the two consistent.
The full chemical composition of a C-type alloy shows why a grade-name declaration is never enough: the same UNS can be made to slightly different residual limits by different mills, and only the heat-specific certificate reveals what your particular lot contains.
Short answer: nickel alloys rarely contain tin, tungsten or gold in meaningful amounts, but cobalt is common in high-temperature grades, and cobalt sourced through the DRC supply chain is exactly what the Conflict Minerals Regulation targets.
The 3TG metals are tin, tungsten, tantalum and gold. Nickel alloys are not tin- or tungsten-heavy, but cobalt appears deliberately in many superalloys for strength and corrosion resistance, and tantalum is used in a few precipitation-hardening chemistries. Because cobalt is mined in the Democratic Republic of the Congo and neighbouring countries, a credible conflict-minerals statement must name the smelter and the country of origin for the cobalt in your heat.
A trader cannot name a smelter it never dealt with. A mill that poured the heat bought its cobalt from a known smelter and can show the due-diligence record. When your customer runs a compliance portal (IMDS for automotive, or a proprietary ESG system), they will ask for exactly that traceability — and a generic "we comply" line will bounce the submission back to you.
This is why, for any corrosion-resistant grade specified for chemical plant, the material declaration should travel with the order from day one, not arrive as an afterthought when the auditor is already at the door.
Short answer: write the declaration requirements into the PO as measurable, rejectable clauses — heat number, SVHC statement, conflict-minerals statement, full chemistry, and mill letterhead with a signatory.
A declaration obligation that lives only in your quality manual is unenforceable at goods-in. Move it into the order. State the standard you are buying against (for example REACH (EC) 1907/2006 and the Conflict Minerals Regulation (EU) 2017/821), name the documents you require, and state that a missing or generic declaration makes the lot rejectable at the supplier's cost.
Also require that the declaration reference the same heat number as the mill test certificate, so the two papers can be reconciled in seconds. Where you resell into a regulated industry, ask for the declaration in a structured form (an IMDS entry, or an XML/CSV of element mass percentages) so your own compliance team can upload it without retyping.
Finally, keep the declaration with the rest of your procurement evidence so that, years later, you can prove the heat you imported was declared correctly — the audit question is rarely "is it compliant today" but "can you prove what you imported five years ago."
Short answer: the four documents that normally govern a nickel alloy declaration into Europe are REACH, the CLP Regulation, the Conflict Minerals Regulation, and — for electrical/electronic end use — RoHS.
| Instrument | What it requires | Trigger for nickel alloy |
|---|---|---|
| REACH (EC) 1907/2006 | SVHC communication down the chain when > 0.1% w/w present | Nickel and nickel compounds on the candidate list |
| CLP Regulation (EC) 1272/2008 | Classification, labelling and safe-use of hazardous substances | Labelling of nickel-containing articles and SDS where relevant |
| Conflict Minerals Reg. (EU) 2017/821 | Due diligence on 3TG in the supply chain | Cobalt and tantalum content of superalloys |
| RoHS Directive 2011/65/EU | Restriction of hazardous substances in EEE | Only if the alloy ends in electrical/electronic equipment |
Short answer: before you pay, confirm the declaration names your heat, states the SVHC position with numbers, covers cobalt/tantalalum origin, is on mill letterhead, and is filed with the certificate.
| Check | Pass criterion |
|---|---|
| Heat number matches MTC | Declaration cites the exact heat on the certificate |
| SVHC statement present | Names substance(s) and concentration, or states none > 0.1% |
| Conflict-minerals statement | Names Co/Ta smelter and country of origin |
| Full chemistry disclosed | Element table matches the certified composition |
| Signatory and letterhead | Named person, company, date, contact |
| Filed with the order | Stored with MTC for future audit |
Yes, if the article contains an SVHC above 0.1% w/w, which nickel alloy normally does because nickel and its compounds are on the candidate list. The declaration does not have to be complex, but it must name the substance and give safe-use information; a bare "REACH compliant" sentence is not sufficient and will not satisfy an auditor or a customer's compliance portal.
No. REACH and the Conflict Minerals Regulation follow the actual substance in the article, not the trade name. Two heats of the same UNS can carry different residuals and a different cobalt origin, so only a heat-specific declaration tied to your mill certificate proves what you actually imported.
They can forward a declaration from the mill that poured the heat, provided they name that mill and the heat number. What they cannot do is invent one. If a trader hands you an anonymous generic form with no heat number and no mill identity, treat it as unverified and reject it until the real mill paper arrives.
Usually not tin, tungsten or gold in meaningful amounts, but cobalt is common in high-temperature grades and tantalum appears in a few, and both can originate from the DRC supply chain. A credible conflict-minerals statement must name the smelter and country of origin for that cobalt — which only the melting mill can truthfully provide.
REACH governs substances of very high concern in articles generally and almost always applies to nickel alloy; RoHS restricts hazardous substances only in electrical and electronic equipment, so it matters only if your alloy becomes part of an EEE product. Ask your customer which applies to the end use before assuming.
Compare the declared element table against the chemistry on the EN 10204 certificate for the same heat number. If the numbers disagree, or the declaration carries no heat number at all, it was not written for your lot. Buy only where the mill issues both papers from the same heat so they reconcile automatically.
As the importer of record into the EU, you carry the primary liability for a non-compliant import. That is why the purchase order must shift the risk back to the supplier: require a heat-specific, signed declaration and state that a false or generic one makes the lot rejectable at the supplier's cost.
If your EU customer or customs broker is asking for a REACH SVHC statement, a conflict-minerals declaration or a full material disclosure and your current supplier cannot produce one tied to your heat, tell us the grade, UNS and intended end use. We will quote nickel alloy with a heat-specific declaration — SVHC position stated with numbers, cobalt and tantalum origin named, full chemistry reconciled to the mill certificate — issued on mill letterhead and filed with the order so you can prove compliance years later.
