01 / Quality framework
Checkpoints are defined by the project.
The exact inspection scope depends on product structure, intended use, agreed specifications and buyer requirements.
Incoming material check
Review relevant material information and project-specific requirements before production.
First-piece confirmation
Confirm the initial production result against the approved reference where required.
In-process inspection
Monitor defined product characteristics during production.
Final inspection
Review the finished product and packaging against the agreed project standard.
Shipment documentation
Prepare the commercial and quality documents agreed for the order.
02 / Material baseline
Confirmed product-line material information.

03 / Certification support
Certification Support for Your Target Market
We support third-party testing, documentation and certification coordination based on your product, intended use and destination market.
Project-specific coordination
- Target market review
- Testing scope discussion
- Documentation coordination
- Third-party communication support
CE, CPC, FDA, LFGB or ISO are not presented as blanket existing certifications for every product configuration.
04 / Evidence layers
Match the document to the material, product and order.
Available records include selected raw-material reports and product-specific test reports. Applicability must be checked against the current design, formulation, color, components, intended use and target market.
Specified raw materials
Third-party SGS reports are available for selected silicone raw-material grades and listed food-contact, EN 71-3 and restricted-substance scopes. Supplier-material evidence does not establish finished-product compliance.
Submitted product samples
Selected drawing mat, food-contact silicone, storage-bag and other samples have product-specific reports. Each result applies only to the identified sample and stated test scope.
Order-level verification
Before a document is used, the current order should be matched by product identity, bill of materials, color, printing, accessories, age grading, use conditions and destination market.
Important: A test report is not government approval, and a customer-specific CPC cannot automatically be reused for another importer, brand or production period. Read the buyer's compliance-document guide.
05 / Traceable communication
Approve the standard before production.
A custom project works best when design files, sample references, packaging requirements and inspection expectations are documented before mass production begins.
- Design and sample confirmation
- Agreed product specifications
- Project-defined inspection points
- Final packing requirements
