Calendrier des brosses à dents électriques OEM : Guide du processus semaine par semaine (2026)

Commencez la première semaine en rédigeant un Demande de devis (RFQ) et l'envoyer à 4-6 usines simultanément. La qualité de votre appel d'offres détermine la qualité des devis que vous recevrez en retour. Les demandes vagues donnent lieu à des réponses vagues et à des prix gonflés qui ne sont évidents que plus tard.

• Define product specifications: Drive technology and specified motion metric, battery voltage and capacity/Wh, applicable ingress-protection target, handle dimensions, brush-head type, charging method, and operating modes.
• Fixez vos quantités cibles : Indiquez la quantité de votre commande initiale et le volume annuel prévu. Les usines fixent des prix différents pour 500 et 5 000 unités.
• List destination-market compliance requirements: identify applicable product rules and evidence for the model and configuration; confirm testing and documentation with the laboratory or qualified adviser.
• Spécifier les exigences en matière d'emballage : Dimensions de la boîte de vente au détail, carte d'insertion, carton principal, exigences en matière d'étiquetage Amazon-ready
• Identifier 4 à 6 usines candidates : Utilisez les annuaires de Canton Fair, le filtre Alibaba Gold Supplier, Made-in-China.com, ou des références directes.

Compare quotations on identical specifications, quantity, Incoterms, testing, packaging, and documentation. Assess total landed cost and assumptions; price alone does not establish supplier quality or future rework cost.

• Comparez les devis sur la même base : Confirmer que tous les devis utilisent les mêmes incoterms (généralement FOB Shenzhen), incluent les mêmes certifications et couvrent des spécifications d'emballage identiques.
• Verify the supplier: Check its business registration and any claimed ISO 9001 certificate. For comparable products, request model-specific test reports and conformity documents relevant to your target market. CE is a conformity mark; FCC requirements depend on the product configuration.
• Évaluer la vitesse de communication : Track response times during evaluation and agree on communication expectations and escalation contacts before production.
• Demander le profil de l'usine : Combien de lignes de production ? Capacité annuelle ? Principaux clients actuels (sous couvert d'anonymat) ? Ont-ils déjà exporté vers votre marché cible ?
• Shortlist suppliers for further review. If needed, commission a scoped factory audit and obtain a current quotation from the provider.

After scope and commercial terms are agreed, engineering reviews design, tooling, materials, assembly, and available processes. The number of questions and response time depend on the project.

• DFM review: Ask engineering to identify design, tooling, assembly, and process questions and document any proposed changes.
• Review proposed CAD and tooling designs before authorizing fabrication. Changes after work begins may affect engineering, time, and cost; define approval and tooling ownership in writing.
• Confirmation des matériaux : Confirmer le matériau du manche (ABS / PC / mélange ABS+PC), le matériau des poils (qualité nylon / DuPont Tynex) et les spécifications du surmoulage TPE/caoutchouc.
• Document the relevant vibration or brush-head movement metric and test method; distinguish VPM, Hz, and rotational speed. Do not call sonic operation ultrasonic without supporting frequency data.
• Tooling cost and payment timing depend on design and contract. Agree amount, ownership, acceptance milestone, and payment triggers in writing.

During mold fabrication, request updates at agreed milestones. Toolmaking requires inspection and adjustment; the appropriate correction depends on the issue and engineering assessment.

• Tooling lead time and durability depend on design, material, process, workload, production conditions, and maintenance. Obtain a project-specific estimate.
• Demander des photos de l'état d'avancement des travaux : Demandez des photos d'usinage CNC à l'achèvement des 50% et 100%
• Tâches parallèles pendant cette attente :
  • Finaliser le logo de la marque et la palette de couleurs pour la texturation des moules
  • Projet de conception de l'emballage de vente au détail pour examen par l'usine
  • Ask your testing lab to review the rules and test scope for the intended product and destination markets.
  • Prepare importer-of-record arrangements if required for the destination and transaction.
• Tool life depends on grade, heat treatment, mold design, resin, production conditions, and maintenance; quoted shot counts are not universal guarantees.

A first mold trial (often called T1) evaluates molded parts and fit. It may identify dimensional, surface, or assembly issues and is not necessarily a complete functional product.

• Contrôle dimensionnel T1 : L'usine mesure les dimensions critiques par rapport aux dessins approuvés à l'aide d'une MMT (machine à mesurer les coordonnées) ou d'un pied à coulisse.
• Examen de l'état de surface : Vérifier la texture, le niveau de brillance, la visibilité du plan de joint, ainsi que les éventuelles marques d'enfoncement ou lignes de soudure.
• Procès de l'Assemblée : Les moitiés du boîtier sont assemblées avec les composants internes (circuit imprimé, moteur, batterie) pour vérifier l'ajustement et l'empilement des tolérances.
• T1 findings and corrective actions:
  • Inspect flash, sink marks, weld lines, fit, and surface texture against the drawing and sample criteria.
  • Ask engineering to identify root cause before approving a design, process, or tooling change.
  • Record corrective actions and re-trial timing in the project schedule; no single repair or turnaround applies to every case.
  • Review the updated sample before approving the next stage.
• Demande d'échantillons T1 physiquement expédiés : Même avec des photos, l'évaluation pratique révèle des éléments qui échappent à l'appareil photo. Qualité tactile, répartition du poids, sensation des boutons

The pre-production sample should represent the agreed design closely enough for review. Define tests, sample size, conditions, acceptance criteria, and any changes requiring reassessment.

• Functional sample testing:
  • Battery runtime: Define sample, charge state, operating mode, load, and stop criteria. One condition does not establish runtime for every mode or battery.
  • IPX7 immersion: Use applicable IEC 60529 conditions, commonly 1 m for 30 minutes for the relevant enclosure. Longer duration is not an IPX7 requirement; an air-pressure screen is not the water test.
  • Test de chute : Agree sample, height, surface, orientations, repetitions, and pass criteria in the project protocol.
  • Brush-head attachment: Define sample, cycle count, and evaluation criteria in the product specification.
  • Charging/cycle test: Specify charger, battery, cycle count, measurements, and acceptance criteria.
  • Vibration measurement: Document instrument, measurement point, method, and metric; distinguish sonic vibration from ultrasonic frequency and rotational speed.
  • Temperature test: Define product state, exposure duration, operating condition, and criteria; limited testing does not prove all-environment performance.
• Examen du prototype d'emballage : Vérifier les couleurs d'impression de la boîte de vente au détail (demander une épreuve Pantone précise), la lisibilité du code-barres et l'ajustement de la carte d'insertion.
• User manual review: Check labeling and instructions against the requirements applicable to each destination market and product configuration.

After sample and commercial terms are approved, issue a purchase order and confirm the production slot. Define specifications, quantity, price, delivery terms, inspection criteria, and payment schedule in writing.

• Délivrer un PO formel : Le bon de commande signé doit préciser les quantités exactes par UGS, le prix unitaire, les Incoterms, le délai de livraison, les spécifications d'emballage et les conditions de paiement.
• Confirmation du calendrier de production : L'usine fournit un diagramme de Gantt ou un calendrier de production indiquant la date de début, l'achèvement prévu et les étapes du contrôle qualité.
• Component procurement: Confirm availability and lead times for specified PCBs, batteries, motors, and materials with the supplier; update the project schedule if an item is not ready.
• Packaging production kickoff: Coordinate artwork approval, production quantity, and delivery timing with the packaging supplier and assembly schedule.
• Inspection planning: Agree the inspection scope, provider, sample plan, and timing with the supplier and inspector; availability varies.

Document production checkpoints, test coverage, sample plans, limits, and failure handling against the approved specification.

• Inline quality checkpoints (document the agreed plan):
  • Housing: check dimensions and visible defects against the approved specification and sampling plan.
  • PCB: document test coverage and limits; describe a check as 100% only if each unit receives the stated test.
  • Assembly: verify alignment and seals against the specification. An air-pressure screen is not an IEC 60529 water-ingress test.
  • Final function: identify the functions tested per unit and how failures are recorded and handled.
  • Packaging: verify SKU, labels, accessories, and carton data against the approved specification.
• Demander des photos/vidéos hebdomadaires de la production : Unités terminées sur la ligne, registres d'inspection CQ et ligne d'emballage en fonctionnement
• Suivre l'évolution de la production : For example, compare reported output with the production schedule and order quantity; investigate material variances early.
• If testing is required, confirm representative samples, scope, lab schedule, and production-change implications with the lab; timing is not guaranteed.

Pre-shipment inspection can check goods against the agreed purchase order and acceptance plan. Define scope and process in advance; it does not guarantee every shipped unit.

• Champ d'application de l'inspection avant expédition :
  • Quantity: compare physical count with the PO and any tolerance expressly agreed in contract.
  • Sampling: specify procedure, inspection level, sample size, defect classes, and acceptance/rejection numbers. AQL is a plan parameter, not measured defect rate; MIL-STD-1916 uses verification levels, not an AQL table.
  • Workmanship: assess surface, color, assembly, and agreed criteria.
  • Function: identify test functions, sample plan, and pass criteria.
  • Packaging: verify carton markings, accessories, and barcodes against the approved specification.
  • Carton drop testing: use the agreed protocol for height, orientations, surface, repetitions, and acceptance criteria.
• Choose an independent provider, buyer-appointed representative, or supplier records based on the agreed scope and evidence requirements. Fees and availability vary; confirm in writing.
• Document the nonconformity, corrective action, rework, and re-inspection criteria. Added time depends on the issue and agreed disposition.
• Prepare documents according to route, product, battery configuration, destination, and buyer requirements. Use a certificate of origin or conformity document only when applicable.

The forwarder coordinates pickup and export formalities. Clearance timing depends on the shipment and its documents; confirm cutoffs and required records for the chosen service.

• Sea freight planning examples:
  • Shenzhen to Los Angeles: request a current route and service estimate.
  • Shenzhen to Hamburg or Rotterdam: request a current route and service estimate.
  • Shenzhen to Tokyo or Osaka: request a current route and service estimate.
  • Shenzhen to Sydney: request a current route and service estimate.
• Air freight may suit samples or urgent shipments. Transit and cost depend on route, service, chargeable weight, battery acceptance, and current capacity; compare current quotes.
• Classification depends on product configuration, jurisdiction, origin, and import date. Treat HS 8509.80 only as a possible heading to investigate, not a final national tariff code or duty.
• Shipment document checklist (confirm what applies):
  • Commercial invoice with accurate transaction value and required shipment information.
  • Packing list with package count, weights, dimensions, and contents as required.
  • Bill of Lading or Air Waybill for the selected service.
  • Certificate of origin only if required by destination, buyer, or applicable procedure; confirm correct form and origin rules.
  • Applicable conformity documentation for the product and destination.
  • FCC documentation only when applicable to the product and import.
  • Battery test summary and shipping information required for the battery design and shipment mode.

Prepare import paperwork before arrival. Confirm free time, storage or demurrage terms, and broker deadlines from current carrier and port information; charges vary.

• Share documents according to the broker’s agreed lead time. Pre-arrival review can identify gaps; no fixed number of days applies to every shipment.
• For applicable U.S. vessel shipments, determine whether ISF applies and submit required information within the regulatory timeframe before loading. ISF is not a general air-freight filing.
• For EU imports, confirm the economic operator and importer arrangements, applicable conformity documents, and customs registration requirements with the importer and broker. Keep these separate from the rules for Great Britain and Northern Ireland.
• Confirm the conformity route for Great Britain or Northern Ireland and the product. Great Britain recognizes CE alongside UKCA for many applicable products under current arrangements; Northern Ireland differs.
• Droits à l'importation à budgétiser :
  • US: duty and additional tariffs depend on final classification, origin, product details, and import date. Check current official sources and obtain broker advice.
  • EU: determine duty from the final classification, origin, and import date; do not rely on a generic percentage.
  • UK: determine duty from the final commodity code, origin, and import date.
• Prepare fulfillment requirements before dispatch. For Amazon FBA, confirm current carton, labeling, prep, and shipment-plan requirements in Seller Central; these differ from standard third-party logistics.

La cargaison est dédouanée et livrée à votre entrepôt ou à votre centre de traitement des commandes. Le projet OEM est terminé. Mais le travail n'est pas terminé. La réception est un point de contrôle de la qualité que de nombreuses marques négligent à leur détriment.

• Reconcile carton count and visible condition, then inspect units under the receiving plan agreed for the order. Any percentage sample is project-specific, not universal.
• Mise à jour du système d'inventaire : Enregistrez les numéros de lot, les dates de production et les codes de lot. Ces éléments sont importants pour les réclamations au titre de la garantie et les rappels éventuels
• Amazon FBA receiving (if applicable): Reconcile delivered cartons and monitor receiving status against the shipment plan created before dispatch. Inventory availability depends on Amazon's processing.
• Photographie et mise à jour des listes : Si vous ne disposez pas encore de photographies de produits, organisez immédiatement une prise de vue en interne ou en studio. Vous voulez que les listes soient en ligne dans les jours qui suivent la mise à disposition de l'inventaire
• Débriefing du projet : Documentez ce qui s'est bien passé, ce qui a causé des retards et ce que vous feriez différemment. Ce document devient le mode opératoire normalisé de la fabrication pour le prochain cycle de production.
