| Material Safety | Materials should be suitable for cosmetic contact and free from avoidable contamination risks. | Material specifications, safety data, migration or compatibility test reports, and incoming-material inspection records. | Packaging can affect product stability, odor, color, and consumer safety. |
| Quality Management | A documented quality system with defined inspection procedures, traceability, and corrective actions. | Quality manual, inspection standards, batch records, nonconformance reports, and audit documentation. | Consistent controls reduce defects across repeated production batches. |
| Dimensional Accuracy | Critical dimensions should be measured against approved technical drawings and agreed tolerances. | Engineering drawings, sampling plans, dimensional inspection reports, and approved reference samples. | Accurate components improve assembly, filling, sealing, and shelf presentation. |
| Product Compatibility | Compatibility testing should cover the actual formula, closure, decoration, and storage conditions. | Compatibility test plan, filled-pack samples, leakage results, and accelerated-aging observations. | A visually attractive package is unsuitable if it leaks, cracks, swells, or reacts with the formula. |
| Decoration Quality | Color, print registration, coating adhesion, gloss, and surface appearance should match an approved master sample. | Color standards, rub-resistance tests, adhesion tests, artwork proofs, and first-article approval records. | Reliable decoration protects visual consistency and reduces rework or rejected deliveries. |
| Minimum Order Quantity | The minimum order should match the buyer’s launch volume, inventory capacity, and demand forecast. | Written quantity tiers for standard, customized, decorated, and newly tooled items. | A suitable minimum order reduces excess inventory and lowers launch risk. |
| Sampling and Tooling | Samples should be available before mass production, with tooling ownership and revision terms clearly stated. | Sample timeline, prototype approval process, tooling quotation, mold-maintenance terms, and ownership clauses. | Clear development procedures prevent unexpected costs and approval delays. |
| Production Capacity | Capacity should be demonstrated through equipment information, realistic lead times, and production planning. | Capacity statement, machine list, production schedule, subcontracting disclosure, and contingency plan. | Capacity visibility helps prevent missed launch dates and unstable supply. |
| Lead-Time Reliability | Quoted lead times should distinguish sampling, tooling, production, decoration, and shipping stages. | Written production schedule, milestone dates, historical delivery records, and delay-escalation process. | Transparent scheduling supports accurate inventory and marketing planning. |
| Sustainability Options | Offerings may include recycled content, refillable designs, mono-material construction, or reduced packaging weight. | Material composition, recycled-content declarations, recyclability guidance, and environmental certifications where applicable. | Verified material information supports responsible design and more accurate environmental claims. |
| Packaging and Logistics | Export cartons should protect components from impact, moisture, abrasion, and excessive movement during transport. | Carton specifications, packing diagrams, pallet details, drop-test records, and shipping documents. | Effective packing lowers transit damage and improves landed-cost predictability. |
| Communication and Support | A clear contact process, prompt technical replies, and written approvals should be available throughout development and production. | Project communication plan, response-time expectations, approval workflow, and after-sales procedure. | Strong coordination reduces misunderstandings involving artwork, specifications, and delivery dates. |
| Commercial Transparency | Quotes should separate product, decoration, tooling, testing, packing, shipping, and applicable taxes or fees. | Itemized quotation, payment terms, validity period, tooling charges, inspection costs, and change-order policy. | Transparent pricing makes suppliers easier to compare and reduces unexpected project costs. |
