ECHA REACH Lookup – SVHC, Annex XIV & XVII Status

What does ECHA REACH Lookup do?

REACH substance lookup with SVHC candidate list status for manufacturers, importers, regulatory affairs and product compliance teams: look up any substance on ECHA CHEM by CAS number, EC number or name and get, in one record, its REACH registration status, whether it is on the Candidate List of substances of very high concern and since when, its Authorisation List (Annex XIV) and Restriction List (Annex XVII) status, and its harmonised classification (CLP Annex VI). Switch to monitor mode and every Candidate List addition reaches you the day ECHA publishes it, per substance and per list, with the reason for inclusion.

A missed Candidate List addition is a breach of the information duty

The Candidate List is updated by ECHA once or twice a year (28 October 2008 to 4 February 2026: 253 entries). Each addition starts legal clocks for everyone who makes, imports or sells articles containing that substance above 0.1% weight by weight:

• Article 33 REACH: suppliers of such articles must give their customers enough information for safe use, at least the name of the substance, immediately after the inclusion; consumers may ask for it and must be answered within 45 days.
• Article 7(2) REACH: producers and importers of such articles must notify ECHA within six months if the substance is present above one tonne per year.
• Article 9(1)(i) of the Waste Framework Directive: suppliers of such articles must notify them in ECHA's SCIP database.
• Article 31 REACH: safety data sheets must mention the inclusion; downstream users receive updated SDSs.

Nobody sends a letter. ECHA publishes the update on its website and the obligations apply from that day. A company that learns of an inclusion at the next annual review has been out of compliance for months; market surveillance authorities check Article 33 information actively, and non-compliance is an offence in every member state.

This Actor does two things about that: it answers, for any substance, what is its status today, and it watches the lists so that what changed arrives as a dataset item, a webhook and, if you wish, an e-mail, on the day.

Monitor mode: the lists, and your substances

Set mode to monitor, choose the lists to follow, add the substances of your portfolio, and schedule the task (daily is right for the Candidate List; ECHA publishes updates on working days).

• The first run records a baseline of every entry of the followed lists and the current status of every watched substance. Baseline entries are delivered as baseline records so you can see what is being watched; they are free. Each watched substance is looked up once, at the lookup price.
• Every later run delivers only what changed: a substance added to a followed list (with its date of inclusion and reasons), an entry that changed (a sunset date, a group entry that gained members, a restriction amended) or one that was removed, and a watched substance whose status changed (it entered the Candidate List, got an Annex XIV entry, became restricted, lost its registration, gained a harmonised classification). A run in which nothing changed costs the start fee only.
• The summary of each change is written for a compliance inbox: n-hexane (110-54-3): now on the Candidate List (included 2026-02-04; Specific target organ toxicity after repeated exposure (Article 57(f) - human health)).
• The webhookUrl receives a POST with the run's summary and the changes. Point it at your ticketing system, Slack or an e-mail bridge.

Sources

Everything comes from ECHA CHEM (chem.echa.europa.eu), the European Chemicals Agency's chemicals database, through the same JSON interface its own web application uses: substance search, the regulatory lists, per-substance obligations, harmonised classifications and REACH registration dossiers. There is no full-database download for these lists, and ECHA's legal notice prohibits systematic copies of its databases; this Actor makes only the requests needed for your lookups and pages through a followed list once per run, paced at four requests per second.

• Reuse of ECHA data is permitted for commercial purposes with attribution. Records delivered by this Actor should carry: Source: European Chemicals Agency, https://echa.europa.eu/.
• CAS Registry Numbers are the property of the American Chemical Society; ECHA provides them so that regulatory requirements can be fulfilled, which is what this Actor uses them for.
• SCIP (the database of articles containing Candidate List substances) is not included: ECHA offers no interface to it and its dissemination has been delayed since 2026. The Actor tells you that a substance requires a SCIP notification; it does not read SCIP.
• ECHA CHEM also holds the EUCLEF cross-references to other EU legislation; they are counted (otherLegislationReferences) but not delivered, as their terms exclude resale.

Features

• SVHC candidate list check per substance: listed or not, direct or group entry, date of inclusion and Article 57 reasons
• Authorisation List (Annex XIV) status with sunset date, latest application date and remarks
• Restriction List (Annex XVII) entries that cover the substance directly or through a group, with the amending regulation and the link to the conditions
• REACH registration status: active and inactive dossiers, full versus intermediate registrations, tonnage band, latest update
• Harmonised classification (CLP Annex VI): hazard classes, H-statements, signal word, pictograms and a cmrCategory1 flag
• CAS and EC number check-digit validation before anything is searched, and exact-name matching so a lookup never returns the wrong substance
• Candidate List monitor: every addition, change or removal on the followed lists on the day ECHA publishes it, with a webhook
• Live from ECHA CHEM: every field is what ECHA says at the moment of the run, never a copy
• Runs through the Apify API, on a schedule, or from Make, Zapier and n8n

Use cases

Manufacturers and importers of articles: the Article 33 check

Put the substances of your bill of materials (CAS numbers from the supplier declarations) in substances, run once for the current picture, then switch the task to monitor mode and schedule it. candidateList.listed with dateOfInclusion is the Article 33 trigger; restrictionList.entries tells you whether an article may be placed on the market at all; authorisationList.sunsetDate is the day a use without authorisation becomes illegal.

Regulatory affairs: portfolio screening

A thousand substances cost $200 and take about ten minutes. Sort the dataset by harmonisedClassification.cmrCategory1, candidateList.listed and registration.status and you have the substitution shortlist and the list of substances whose registrations are inactive (a supplier whose registration lapsed cannot lawfully supply above one tonne).

Product compliance and PLM software

Call the Actor from your backend when a new material is created, and store the record with the material:

// npm install apify-client
import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: process.env.APIFY_TOKEN });
const run = await client.actor('lwsdjfls/echa-reach-svhc-lookup').call({ substances: ['117-81-7', 'EC 203-777-6', 'Bisphenol A'] });
const { items } = await client.dataset(run.defaultDatasetId).listItems({ clean: true });

for (const { payload } of items) {
    if (payload.status !== 'found') { console.warn(payload.input, payload.status, payload.statusReason); continue; }
    const flags = [
        payload.candidateList.listed && `SVHC since ${payload.candidateList.dateOfInclusion}`,
        payload.authorisationList.listed && `Annex XIV, sunset ${payload.authorisationList.sunsetDate}`,
        payload.restrictionList.listed && `Annex XVII entry ${payload.restrictionList.entries.map((e) => e.entryNumber).join('/')}`,
        payload.harmonisedClassification?.cmrCategory1 && 'CMR 1A/1B',
    ].filter(Boolean);
    console.log(`${payload.substance.name} (${payload.substance.casNumber}): ${flags.join('; ') || 'no listing'}`);
}

Distributors and e-commerce: restricted substances in consumer articles

Annex XVII limits what may be in toys, textiles, jewellery, packaging and consumer mixtures. Look up the substances your suppliers declare and act on restrictionList.entries; each entry links to the conditions in EUR-Lex.

How to use it

1. Keep Mode on lookup and paste what your suppliers gave you into Substances: CAS numbers, EC numbers or plain substance names, mixed freely. A bill of materials pasted as one column per line is the normal starting point. Each entry becomes one record, including the ones ECHA does not know.
2. Read the substances view. Per substance you get registration status, whether it sits on the Candidate List with the date and the reason it was added, its Annex XIV authorisation and Annex XVII restriction status, and the harmonised classification when Include harmonised classification is on.
3. Switch Mode to monitor, give it a State key and schedule it. The Candidate List is updated in batches, usually twice a year but not on a fixed date, and the obligation to inform your customers starts the day a substance is added. A scheduled monitor with a webhook tells you that day instead of at your next manual review.

The changes view is what a monitor produces, and listEntries is the list itself if you would rather hold a copy. A substance that ECHA answers only partially still produces a record with the fields it did return, so a half answer is visible rather than missing.

Know where the answer stops. This reports what ECHA CHEM publishes about a substance. It does not know your product, your concentrations or your tonnage, so it cannot tell you whether an article of yours crosses the 0.1 percent threshold or whether you need an authorisation. It gives a compliance team the regulatory status per substance, quickly and with the dates attached, and the assessment stays theirs.

Input

Field	What it does	Example
mode	lookup delivers every substance on every run; monitor records a baseline and later delivers only changes.	"lookup"
substances	One per line: a CAS number, an EC number (204-211-0 or EC 204-211-0) or a substance name. Numbers are check-digit validated; names must equal a name ECHA knows. Lookups that find nothing are free, so they share an allowance of 1,000 requests per run, retries included, plus maxSearchPages per substance found: a lookup starts only while its search requests (one per CAS or EC number, up to maxSearchPages per name) still fit next to those of the lookups in progress, which can take a run past the allowance with their retries and, when they fail, the requests after their search. The substances that do not fit are logged as not looked up. CAS and EC numbers are looked up, and listed, before names.	["117-81-7", "EC 203-777-6", "Bisphenol A"]
lists	Regulatory lists whose entries are followed in monitor mode.	["candidateList", "authorisationList", "restrictionList"]
includeClassification	Adds the harmonised classification and labelling (CLP Annex VI).	true
includeRegistrations	Adds the REACH registration status.	true
maxSearchPages	How many pages of 100 search results are scanned for an exact name match ("Bisphenol A" is on page 2).	3
maxSubstancesPerRun	Caps the charged lookups in one run. In lookup mode a run also starts at most twice this many lookups, because unknown numbers and unmatched names are free but still take requests; the rest is logged as not looked up.	1000
maxChangesPerRun	Monitor mode: caps the charged changes in one run. When more change at once, delivery stops at the cap and the rest follows in the next runs.	25
maxConcurrency	Substances looked up at the same time; requests to ECHA CHEM are paced at 4 per second regardless.	3
webhookUrl	Receives a POST with a summary after each run that delivered results or changes; must be a public http(s) address and is stored encrypted.	https://hooks.example.com/reach
stateKey	Separates independent monitors. Defaults to the task ID, so each saved task keeps its own baseline.	portfolio-2026

  "substances": ["117-81-7", "EC 203-777-6", "Bisphenol A", "7439-92-1"],
  "includeClassification": true,
  "includeRegistrations": true
}

A CAS number (117-81-7), an EC number (204-211-0 or EC 204-211-0) or a name, one per line. Numbers are validated against their check digit before anything is searched, because a mistyped CAS number silently finds a different substance. Names must equal a name ECHA holds for exactly one substance (ECHA's own search ranks "Bisphenol A" 127th of 225 results; the Actor scans the pages and picks the record that carries the name). When several records carry the name, the result is ambiguous, the candidates are listed with their CAS numbers, and nothing is charged.

Monitor mode:

}

Output

One record per substance, CAS and EC numbers first, then names. In monitor mode, one record per change (changeType added, changed or removed) with structured changes and a summary. A monitor run that could read none of its followed lists and watched substances (ECHA CHEM not answering, or a spending limit too low for the first lookup) ends as failed, charges nothing and keeps the recorded state, so the next run still reports every change since the last successful one. A watched number with a wrong check digit needs no answer from ECHA CHEM, so with one in the list such a run can end as partial instead.

• status: found, not-found (ECHA has no substance under that number), ambiguous (several substances carry that name; the candidates are listed), invalid-identifier (wrong CAS or EC check digit) or lookup-failed (ECHA CHEM did not answer completely, or had stopped answering before the substance was looked up; nothing charged)
• substance: ECHA's identity of the record: name, EC number, CAS number, other CAS numbers ECHA associates with it, IUPAC name, molecular formula, CLP index number, synonyms
• registration: registered, inactive-registrations-only (ECHA holds dossiers but none is active, so supplying above one tonne per year is not allowed: "no data, no market") or not-registered, with the number of active and inactive dossiers, full (Article 10) versus intermediate (Article 17/18) registrations, joint submission, tonnage band and the date of the latest dossier update
• candidateList: listed yes/no, direct entry or group entry, the entry's name, date of inclusion and reasons (Article 57 criteria: CMR, PBT, vPvB, endocrine disruption, equivalent concern)
• authorisationList: listed yes/no, Annex XIV entry number, sunset date, latest application date, reasons and the entry's remarks (exempted uses, transitional arrangements)
• restrictionList: every Annex XVII entry that covers the substance, directly or through a group (the phthalates, the PFAS, the CMR entries), with the entry number, the amending regulation and the link to its conditions
• harmonisedClassification: index number, hazard classes and categories (Repr. 1B, Carc. 1A, STOT RE 1), H-statements, signal word, pictograms, the ATP that set them, the date they apply from, and cmrCategory1 (true for a category 1A/1B CMR)
• otherProcesses: further ECHA processes the substance is in (substance evaluation under CoRAP, PIC, biocides, POPs, Drinking Water Directive) and the number of other EU legislation references ECHA holds for it
• sourceUrl to the ECHA CHEM record, and sourceCheckedAt

Every field comes from ECHA CHEM at the moment of the run, not from a copy: the answer for a substance is what ECHA says right now.

Pricing

Event	Name	What it means	Price
apify-actor-start	Actor start	Charged by Apify when a run starts: once for a run of up to 1 GB of memory, and once more for every extra GB. It covers the first five seconds of compute.	$0.00005 per run up to 1 GB of memory ($0.05 per 1,000)
substance-looked-up (primary)	Substance looked up	One substance resolved in ECHA CHEM and delivered with its identity, REACH registration status, Candidate List, Authorisation List and Restriction List status, and harmonised classification. In monitor mode charged once, when a watched substance is first recorded.	$0.20 per substance ($200.00 per 1,000)
change-detected	Change detected	In monitor mode: a substance added to, changed on or removed from a followed list (Candidate List, Authorisation List, Restriction List), or a change in the status of a watched substance.	$1.00 per change ($1000.00 per 1,000)

The example input above (four substances) costs $0.80. A portfolio of 1,000 substances costs $200, once. Following the Candidate List, Authorisation List and Restriction List daily costs the Actor start fee per run (a fraction of a cent) plus $1 per change; the Candidate List gained 2 entries in February 2026 and 1 in November 2025, the Authorisation List and Restriction List change a few times a year. One run never charges more than maxChangesPerRun changes (default 25). A missed inclusion costs a great deal more.

Not charged: substances ECHA does not know, ambiguous names, invalid numbers, lookups that failed halfway, baseline runs, and runs in which nothing changed. Because a lookup that finds nothing is free, such lookups share an allowance of 1,000 requests per run (in either mode), retries included, plus maxSearchPages per substance found. A lookup starts only while its search requests (one per CAS or EC number, up to maxSearchPages per name) still fit next to those of the lookups in progress, which can take a run past the allowance with their retries and, when they fail, the requests after their search. CAS and EC numbers go before names, and the substances that do not fit are logged as not looked up, so remove numbers and names ECHA CHEM does not know from long lists. When ECHA CHEM stops answering (10 lookups in a row without an answer; in lookup mode one more for each substance the run has found, up to 50), new lookups wait and one lookup tries again: it makes each of its requests up to five times, pausing between the attempts for a random time of up to 30, 60, 120 and 120 seconds (under three minutes per request on average), and at least as long as ECHA CHEM asks, if that is two minutes or less. An outage of a few minutes is often waited out, not always; if ECHA CHEM answers, the run goes on, otherwise it starts no more lookups. In lookup mode the substances it did not look up are delivered free with status lookup-failed: run just those again later, because a run of the whole list charges every substance it finds again. A watched substance that a run could not look up (a limit reached, ECHA CHEM not answering) is not recorded yet: the run that first looks it up records it and charges the lookup, not a change.

FAQ

What is the difference between the Candidate List, the Authorisation List and the Restriction List?

The Candidate List (Article 59) names substances of very high concern; inclusion triggers information duties (Articles 7(2), 31, 33, SCIP) but does not forbid anything. Substances are moved from it to the Authorisation List (Annex XIV) with a sunset date, after which every use in the EU needs an authorisation. The Restriction List (Annex XVII) limits or bans specific uses, concentrations or articles regardless of the other two lists; a substance can be restricted without ever being on the Candidate List.

A substance is "listed" through a group entry. What does that mean?

Many entries cover a group ("phthalates", "PFAS", "lead compounds"). ECHA links the member substances to the entry; the Actor reports entryType: "group" with the entry's name, and the obligations are the same as for a direct entry.

Why is a name not found while ECHA's website finds it?

ECHA's search returns every record that mentions the words; the Actor accepts only records that carry the exact name (as ECHA name, EC name, IUPAC name, synonym or trade name), so that a lookup never returns the wrong substance. Use the CAS or EC number when in doubt; both are unique.

How soon after an ECHA update does the monitor report it?

The Actor reads ECHA CHEM live; a change is reported on the first run after ECHA publishes it. Schedule daily on working days at, say, 12:00 CET (ECHA publishes during the Helsinki working day).

Is an SVHC candidate list lookup legal, and does it involve personal data?

The data is public regulatory information published by ECHA for exactly this purpose; ECHA permits reuse with attribution, and no personal data is involved, so the GDPR does not apply to the output. The Actor is not affiliated with ECHA. Regulatory conclusions (whether your article needs a notification, which use is exempted) remain your responsibility; the Actor gives you ECHA's data and the links to the legal texts.
