Do You Need to Retest After an SVHC List Update?

Update, then assess：A list change calls for traceable reassessment, not indiscriminate retesting

ECHA updates the Candidate List when substances are added. After inclusion, companies should assess whether product, material and supply-chain data cover the added substance and current product version. Duties arise from inclusion, while Article 7 notification has its own statutory timing.

The Regulation does not say that every article must undergo new laboratory testing on each update. A stronger process compares declarations, material data and product changes first, then uses updated evidence or targeted testing only where a material gap remains.

Bottom line first

A Candidate List update should trigger product and evidence reassessment.
There is no blanket automatic retest requirement for all articles.
Article 33 and Article 7 have different conditions and timing.
For complex products, consider constituent articles when applying 0.1% w/w.
Keep the list version, decision record and evidence updates.
As checked on 8 August 2026, ECHA's Candidate List contained 253 entries following the 4 February 2026 update.

Information needed before deciding

ECHA Candidate List check date and version
Added SVHC name, CAS/EC number and inclusion date
Product status by part number, revision and market
Whether material declarations explicitly cover the added SVHC
Whether the product contains multiple constituent articles
Concentration and weight basis for each constituent article
Whether the company is an EEA producer or importer
Total annual tonnage of the SVHC
Whether exposure can be excluded and safe-use instructions
Whether SCIP may apply to EU-market supply
Article 7(2) conditions, plus whether the Article 7(3) exposure exclusion or Article 7(6) prior-registration condition applies

Practical decision flow

Capture the official change

Record the added substance, inclusion date and check date from ECHA’s Candidate List.

Screen impact

Use CAS/EC numbers, material categories and supplier data to identify potentially affected parts.

Check configuration

Confirm whether BOMs, materials, processes or suppliers changed since the prior evidence.

Assess each duty

Evaluate Article 33 communication, Article 7 notification/registration and SCIP separately.

Update evidence

Request focused updated data; use testing only for uncertainties documents cannot resolve.

Keep the decision record

Retain list checks, calculations, exception analysis and communication versions.

What different evidence can support

Evidence	What it can support	Important limitation
ECHA Candidate List check record	The official list and date used	It does not establish product content
Updated supplier declaration	A current supplier statement for the added SVHC and named product	Product and material scope still require review
Material composition data	Identification and concentration information for a material or part	Unknown impurities and later changes may not be covered
BOM and change control	Whether the current configuration matches historical evidence	It does not directly establish chemical concentration
Targeted test report	Results for a specified sample and new analyte	It supports only the sampled and analytical scope

Common mistakes

Mistake：Making no review after a list update

**Risk：**New duties and customer information can be missed

**Better approach：**Use an inclusion-date impact assessment trigger

Mistake：Retesting every product blindly

**Risk：**Cost rises without necessarily closing the key data gap

**Better approach：**Start with material and document gap analysis

Mistake：Treating Articles 7 and 33 as the same duty

**Risk：**Tonnage, role or timing is applied incorrectly

**Better approach：**Assess conditions separately

Mistake：Diluting SVHC concentration across the whole complex product

**Risk：**The 0.1% threshold may be misapplied

**Better approach：**Assess constituent articles where applicable

Mistake：Failing to retain the list version

**Risk：**The basis for the historical decision cannot be shown

**Better approach：**Preserve source, date and decision record

Company action checklist

Monitor ECHA Candidate List changes
Include list updates in engineering-change and supplier-management processes
Screen added SVHCs by CAS/EC number
Update supplier questionnaires by part number and revision
Separate Article 33, Article 7 and SCIP decision fields
Use targeted tests only where documents cannot support a material conclusion
Keep traceable customer-information and consumer-response versions

Manager summary

After a Candidate List update, the management task is a documented reassessment, not universal retesting. Compare the added SVHC with the current BOM, material data and company role, then concentrate testing on uncertainties that reliable supply-chain information cannot answer.

Frequently asked questions

Must we retest after every SVHC update?

No. First assess whether existing evidence covers the added substance and current product.

When does Article 33 apply?

It applies to suppliers of articles containing a Candidate List SVHC above 0.1% w/w.

Does Article 7 notification have a tonnage condition?

Yes. Article 7(2) includes producer/importer, SVHC concentration and total annual quantity conditions.

Is SCIP the same as Article 7 notification?

No. SCIP is a separate information-submission duty under the Waste Framework Directive.

How should complex products be handled?

Identify constituent articles and assess the 0.1% threshold according to the applicable legal interpretation.

Does inclusion on the Candidate List itself create a general ban?

No. Inclusion can trigger defined REACH information, notification or supply-chain duties when their conditions are met; it is not itself a general prohibition on every use or article.
