Certifications — ECE R129 & More
Holdum maintains rigorous testing and documentation standards to support our global partners in child passenger safety.
ECE R129 Path: Engineering Standards and Documented SKU Status
ECE R129 represents the global benchmark for child occupant protection, mandating height-based classification, integrated lateral impact criteria, and extended rearward travel. Our i-size-ece-r129-car-seats technical testing framework ensures verified development and certification milestones across key Holdum child restraint models.
Dynamic Side-Impact Protection Benchmarks
ECE R129 defines lateral-impact criteria (including a typical ~24 km/h sled profile) using industry Q-series dummies. Holdum designs reference those regulatory expectations with energy-absorbing structure and deep side wings — detailed test summaries are shared for applicable approved platforms upon request, not as stand-alone public proof numbers.
Stature-Based Grouping
Child fitment is categorized by standing height in centimeters rather than weight alone, ensuring more accurate harness positioning and headrest alignment.
Extended Rear-Facing
Rearward installation is required up to a minimum of 15 months, supporting cervical vertebrae during high-energy frontal impacts.
Homologation Documentation
Documented by Model
Holdum SKU Homologation Status
Factual certification milestones and target stature groups for OEM and wholesale buyers.
Type-approval dossiers are on file for every model in this range: UN ECE R129 (i-Size) type-approval, plus CCC (GB 27887) for the China market. Certificate copies and test reports are released to qualified buyers at RFQ stage.

Conformity of Production Controls
Batch-level dynamic sampling and mechanical checks are performed systematically to align production with certified type-approval specifications.
Head Performance Evaluation
Regulatory head-performance criteria use calibrated Q-series methods; Holdum shares summaries for applicable platforms when buyers request certification data.
Comprehensive Buyer Dossiers
Type-approval certificate copies, test summaries, and installation manuals are provided to prospective brand partners upon commercial request.
Legal Entity & Certification Scope
Holdum is the export brand of Jiangsu Myriad Child Safety Seat Co., Ltd., the legal entity named on the approvals listed above. Certificate copies are issued under the registered company name; the Holdum brand appears on product labelling, packaging and commercial documents. Buyers verifying approval numbers against issuer databases should search for the legal entity name.
Holdum currently holds UN ECE R129 (i-Size) type-approval and China Compulsory Certification (CCC, GB 27887-2011) for the models listed above.
We do not hold these approvals:
- FMVSS 213 — United States (NHTSA)
- CMVSS 213 — Canada (Transport Canada)
- AS/NZS 1754 — Australia / New Zealand
For programmes requiring these standards, buyers must obtain destination-market certification through their own accredited testing body. We can support that process with sample submission, technical files and factory audit access, but we do not issue or hold those certificates.
Products supplied to European and UK markets are covered by the ECE R129 approvals listed above. If your programme requires a standard outside this scope, please raise it at RFQ stage so we can confirm feasibility before sampling.
Transparent CCC Documentation and Market Entry Dossiers
For regional distribution and domestic market clearance, China Compulsory Certification (CCC) documentation for applicable models follows GB 27887, covering MY-166 for the China market. Holdum maintains organized dossiers so OEM and brand partners can request verification paths without treating this page as a substitute for official certificate copies.
Technical File Preparation
We assemble complete structural drawings, material disclosures, harness component verifications, and user manual drafts mapped to regulatory criteria.
Buyer-Accessible Files
Distributors can request standard compliance dossiers, factory audit status overviews, and test progress reports for specific child seat models.
Model Verification Scope
Evaluating product build parameters across convertible, rotating, or booster categories to confirm precise test requirements and documentation paths.
Sample & Test Tracking
Supporting sample submission to designated testing bodies and tracking regulatory test progress (dynamic, flammability, and chemical assessments as applicable).
Dossier Maintenance
Providing validated documentation packages and supporting continuous CoP (Conformity of Production) records for continuous wholesale distribution.
Complete Technical Files and Verifiable Compliance Data Shared with Buyers
Holdum provides qualified distributors, private label brands, and OEM buyers with clear, auditable documentation. From homologation test summaries to batch conformity records, every deliverable is grounded in verifiable engineering evidence. We share these detailed reports to ensure you have the necessary safety data for your product lines.
Direct Access to Regulatory Documentation and Batch Records
International infant and child product procurement requires reliable proof of safety and production consistency. We supply structured technical dossiers upon request to simplify your import declarations, retail audits, and market registrations.
