We systematically structure operational use cases, operating environments, material grades, engineering tolerances, Pantone colors, target order runs, and packaging styles. Confirmed criteria are segregated from items to be confirmed to create an actionable milestone plan.
We collaborate with manufacturing partners to evaluate optimal resin/metal grades, decorative surface treatments (electroplating, UV coating, anodization), printing techniques, and internal enclosure structures. Tooling fabrication (new injection molds) and multi-part sub-assemblies are fully scoped before commitment.
We audit prototypes against functional, dimensional, and tactile standards, compiling structured modification logs. The signed-off physical sample (Golden Master Sample) alongside locked CAD drawings and packaging artwork serves as the frozen baseline for mass production.
We provide transparent milestone updates throughout mass production. When placing repeat orders, we proactively re-audit raw material supplies, supplier tooling wear, and market pricing to prevent quality deviations or supply bottlenecks.
Keep devices, skincare, containers and printed packaging on one project schedule. GAMU coordinates partner factories, tracks approved specifications and samples, records open decisions, and follows up on production, inspection and shipment. Shared records and named factory contacts make the work easier to hand over when a salesperson changes.
Define the intended market, product claims and sales channel before locking the design. We help collect and check partner-factory documents, match them to the proposed product and production site, and coordinate missing tests or registration information with the appropriate specialists.
For beauty devices and electronics, we help review applicable CE documentation, FCC authorization evidence and RoHS records against the model, configuration and intended market. Design or component changes are checked for their effect on the supporting evidence.
For skincare OEM, we help verify the scope of ISO 22716 / GMPC factory documents and request relevant SDS (MSDS) and batch COA records. For US-bound cosmetics, we coordinate factory information needed for applicable FDA facility registration and product listing. Registration or listing does not mean FDA product approval.
Share your importer, marketplace or retailer checklist at the start. We organize document gaps, responsible parties and due dates alongside sampling and production.
Request EXW at an agreed pickup location, FOB Guangzhou for sea freight at a named port, or DDP (Delivered Duty Paid) door-to-door delivery to the US, UK, EU, Australia and Middle East. Available routes depend on the product and destination. Before booking, confirm import arrangements, duties and taxes, delivery access and any unloading charges in the quotation.
Discuss Your Project & Document ChecklistCustom OEM development commences upon specification freeze and receipt of an initial project deposit. First-time engineering support is quoted upfront at up to 5% of product value based on structural design complexity and prototype iterations. Repeat orders for the same product will never incur this engineering fee again.
This engineering support fee is calculated independently from our standard service fee. Once established, subsequent repeat orders, or minor revisions for the same product line will NEVER incur this development fee again.
