Reach Compliance for Dual Mass Flywheel: Buyer Checklist
Procurement teams sourcing a dual mass flywheel need more than a dimensional match. REACH compliance reaches into full material declarations, SVHC screening, coating chemistry, damping grease, rubber or polymer elements, cleaning agents, labels, and export packaging. For EU-bound supply, buyers should confirm that the part, its packaging, and any process chemicals with carry-over risk do not create avoidable exposure during import, warehousing, or customer audits. Driventus is an independent aftermarket manufacturer; brand names are referenced for fitment only.
A controlled sourcing file should trace the part from steel heats and purchased springs through damping medium, final inspection, and export packing. It should include a declaration against REACH (EC) No 1907/2006, an SVHC review against the current Candidate List, and internal controls aligned with IATF 16949:2016 and ISO 9001:2015. For fleets, distributors, repair networks, and importers, the practical question is direct: can the supplier prove consistent build quality, stable chemistry, and documented change control before shipment? A strong reach compliance for dual mass flywheel file answers that question before the first purchase order is released.
What REACH compliance means for a dual mass flywheel
REACH compliance is not a marketing claim, and it should not be reduced to a generic line on a quotation. For a dual mass flywheel, the supplier needs to identify and control substances used across every relevant material stream: steel plates and hubs, friction interfaces, seals, springs, rivets, bearings or bushings, damping grease, surface treatment, cleaning agents, anti-corrosion protection, labels, and packaging. Buyers should expect a signed statement covering REACH (EC) No 1907/2006, backed by a dated process for monitoring SVHC Candidate List updates and Annex XVII restricted-substance changes.
The 0.1% w/w SVHC communication threshold is assessed article by article under EU expectations. A flywheel assembly, therefore, should not be treated as one undifferentiated metal component. Procurement teams need to understand how the supplier evaluates homogeneous materials and discrete subcomponents, particularly where grease, coatings, adhesives, plastics, rubber, paints, or plated finishes are involved. These are often the places where a mechanically acceptable part can still create documentation risk.
Key points to verify:
- Material declaration for all relevant homogeneous materials and subcomponents
- SVHC screening against the current Candidate List, with disclosure where any article exceeds 0.1% w/w
- Confirmation that Annex XVII restricted substances are not intentionally added above applicable limits
- Review of damping grease, anti-corrosion oil, coating, plating, passivation, and cleaning chemistry
- Packaging declaration for inks, adhesives, plastic bags, stretch film, cartons, labels, desiccants, and pallet materials
- Change notification if chemistry, coating, lubricant, supplier source, cleaning process, or packaging material changes
- Named contact responsible for updating the declaration after REACH Candidate List revisions
For importers, best practice is to keep the declaration with the commercial invoice, packing list, certificate of conformity, and batch traceability record. The file should identify the exact part number, production lot, declaration date, supplier name, and document revision, so a warehouse, broker, or end customer can connect the paperwork to the physical goods without guesswork.
Buyer checklist for sourcing compliant flywheels
Use this checklist during RFQ, sample approval, supplier onboarding, and pre-shipment review. The goal is not only to confirm that the dual mass flywheel fits the application. It is also to check whether the supplier can hold the same compliance position across repeat batches. A low price quickly loses its value if the declaration is generic, outdated, or disconnected from the materials actually used in production.
| Item | What to ask for | Why it matters |
|---|---|---|
| REACH declaration | Signed statement tied to exact part number, supplier, date, revision, and batch where possible | Confirms the current regulatory position and avoids generic paperwork |
| SVHC screening | Latest assessment date, Candidate List version, and internal owner for updates | Shows whether the supplier tracks regulatory changes, not only old customer requests |
| Material breakdown | Steel grade family, grease, springs, fasteners, rubber or polymer elements, coatings, plating, labels, and packaging | Identifies where restricted-substance risk may appear |
| Traceability | Lot code, production date, steel or component batch reference, inspection record, carton label, and shipment reference | Supports recalls, customer audits, warranty analysis, and complaint containment |
| Change control | Written notice for formula, material source, coating, grease, cleaning agent, packaging, or process changes | Prevents silent compliance drift after approval |
| Test evidence | Axial runout, radial runout where specified, torque check, end play, angular free travel, imbalance, and visual inspection data | Confirms product consistency and supports quality approval |
| Packaging review | Carton, label, ink, adhesive, plastic bag, desiccant, stretch film, and pallet material information | Ensures the compliance file covers what enters the market, not only the metal part |
| Supplier accountability | Named technical, quality, and compliance contacts | Speeds resolution if customs, distributor, or customer questions arise |
