Your product, visually traced
Every step sits in our chain — with photo evidence, signed reports and one accountable contact.
01 Product design & sampling
Specs, ID, firmware tuning and golden samples — confirmed before tooling.
02 Audited production line
On-site visits before each run. We verify capacity, equipment, working conditions.
03 In-line QC & final inspection
Pre-production samples · DUPRO during production · PSI before shipment.
04 Container loading
Palletised, shrink-wrapped, container-loaded. PI / CI / PL / COO / MSDS handled.
05 Export to your door
Air, sea or courier — we choose the right lane for lead time, weight and destination.
Four capabilities — one accountable contact
Most of our competitors either run their own (limited) factory or hand you a list of suppliers and walk away. We sit between you and production, owning the result.
On-site visits before we onboard a new partner. We verify capacity, equipment, working conditions — and send you the photo evidence.
Pre-production samples · During-production checks (DUPRO) · Pre-shipment inspections (PSI). You choose how strict — we sign the report.
PI · Commercial Invoice · Packing List · COO · MSDS · UN38.3 where applicable. We handle paperwork so the shipment clears.
NDA before samples leave. Your logo, your molds, your tooling — we never reproduce or repackage for another client.
