Supply Chain Management

(1) Pre-production preparation

① Specify detailed technical parameters and avoid ambiguity.

② Implement a reduced lead time compared to the standard (e.g., 25 days for trial orders versus the regular 30-day delivery window) to assess supply chain resilience.

③ Specify internal and external packaging details (e.g., shockproof and moisture-proof requirements) to prevent transportation damage.

④ Sign a contract with punitive terms, clearly defining acceptance criteria, non-conforming goods handling terms (retuen/replacement/discount), intellectual property ownership, etc.

(2) Producing process monitor and control

Require suppliers to provide photo/video documentation at the following four stages: raw material procurement, first article production, semi-finished product inspection, and pre-packaging.

(3) Logistics and delivery verification

① Require suppliers to submit complete logistics documentation (e.g., packing list, bill of lading, customs clearance documents) to evaluate their document management capability.

② Track deviations between actual vs. agreed delivery timelines; conduct root cause analysis (e.g., production delays or logistics failures) for delays exceeding 3 days.

(4) Initial arrival inspection

External packaging and label verification:

① Integrity: Check for damage, moisture, deformation on outer cartons, and signs of resealing (e.g., tampered tape).

② Label information: Verify markings (product name, model, quantity, order number) against order requirements.

③ Special Symbols: Confirm fragile/moisture-sensitive items are marked (e.g.,”↑arrow, umbrella symbol).

Quantity and specification verification:

① Full Counting: Conduct 100% quantity verification.

② Specification Sampling: Randomly inspect 5–10 items for model, color, and size consistency to prevent mixed materials.

(5) Detailed unpacking inspection

Appearance inspection:

① Surface scratches, color deviations, stains

② Assembly gap uniformity (e.g., ≤0.5mm tolerance measured with calipers)

Functional inspection:

① Electronic product: Power-on test, button responsiveness, interface compatibility, etc.

② Mechanical product: Transmission system (e.g., fluency of gears, drive belts, drive chains, etc.), power system (e.g., stability of electric motors, generators, etc.), control system (e.g., validate responsiveness of switches, buttons, indicator lamps, etc.), etc.

(6) Unqualified product handling

Evidence Retention: Photograph/video defects, mark issue locations, and retain samples.

Supplier Communication: Send quality report within 24 hours, demand resolution timeline and propose rework/replacement plans.

(7) Evaluation after trial order

Assign different weights to factors such as quality compliance rate, on-time delivery accuracy, and communication responsiveness. Evaluate suppliers based on their weighted scores and screen out qualified candidates for collaboration.
