Pre-Defining Inspection Scope & Defect Classifications

Inspection parameters are established upfront for exterior defects (scratches, burrs, foreign particles), piece counts, SKU matching, color consistency, print fidelity, and compliance labels. Protocols—100% full inspection or statistical sampling based on ISO/AQL standards—are confirmed according to product value and volume.

Physical Cross-Referencing & Operational Testing

Inbound goods are strictly cross-checked against approved purchase order specifications and golden samples. Precise dimensional tolerances, gross weights, power/functional operations, and mechanical component fit are audited according to customized product checklists.

Defect Documentation & Supplier Remediation

Every defect is documented by classification (Critical, Major, Minor), defect count, and high-resolution photo evidence. Under pre-agreed contract terms, we enforce free factory rework, non-conforming unit replacement, shortage replenishment, and mandatory re-inspection locally in China.

Coordinating Specialized Lab & Compliance Testing

Vacuum leak testing, long-term durability cycling, chemical hazard analysis, and mandatory statutory testing through accredited laboratories (SGS, TÜV, RoHS, PSE) are arranged on demand. We clearly segregate routine visual inspections from destructive lab trials, quoting scopes, and costs upfront.

Multi-Factory Consolidation & Dedicated Project Management

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.

Before combining goods from different factories, reconcile supplier deliveries with the master order list, separate held or rejected stock, and confirm labels, set contents, carton quantities and destination allocations. Release each lot against the agreed inspection result and document checklist.

Inspection Records Matched to Your Product and Destination

Agree the inspection checklist, sample size or full-check scope, defect criteria and release decision before the visit. We link findings to the SKU, approved revision and production lot, with photographs and the agreed report format.

Beauty Devices & Electronics

For beauty devices and electronics, document checks can include CE, FCC and RoHS evidence, with the model numbers, relevant configuration and issuing details checked against the order. Any missing or mismatched evidence is recorded for follow-up.

Skincare OEM & Cosmetics

For cosmetics, the agreed document review can cover ISO 22716 / GMPC production-site records, relevant SDS (MSDS), lot-specific COA and information supporting applicable FDA registration or listing. We identify missing records and coordinate factory responses; physical QC and regulatory assessment remain separate work items.

EXW / FOB Guangzhou / DDP

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.

AQL Sampling Inspection Protocol Example

For larger volume production, statistical sampling based on international AQL standards can be agreed to balance cost efficiency and strict quality control. The following illustrates an agreed sampling protocol for screen-printed cosmetic glass bottles:

Sampling Protocol: Randomly draw and inspect 50 units per master carton of 500 bottles.

  • Critical Defects (1 or more rejects carton): Structural breakage, glass cracks, severe deformation, or incorrect statutory/regulatory print text.
  • Major Defects (3 or more rejects carton): Peeling ink/poor adhesion, artwork misalignment, blurred printing, uneven spray coating, or surface leveling defects.
  • Minor Defects (5 or more rejects carton): Non-functional micro-scratches, minute air bubbles, or negligible surface blemishes.

If any defect threshold is reached, the affected carton/lot is rejected, and GAMU immediately coordinates factory return, sorting, or rework. All findings are logged in an official inspection report with detailed photo documentation and defect counts. Actual sampling ratios and acceptance criteria are tailored to each product category.
