How to Use This Supplier Evaluation Guide<\/h2>\n  <p>Compare electric-toothbrush suppliers in China using ten practical criteria, from drive design and charging to materials, software and production controls. Start with the features your product needs, then ask each supplier for documents and samples that demonstrate its ability to deliver them.<\/p>\n  <p>Confirm the contracting company and factory address, and ask which production steps are subcontracted. Use the same product specification when reviewing samples, test reports and quotations so you can compare offers fairly.<\/p>\n  <p>For an overview of the development and sourcing process, see our <a href=\"\/cn\/oem-odm-%e7%94%b5%e5%8a%a8%e7%89%99%e5%88%b7%e5%88%b6%e9%80%a0%e6%8c%87%e5%8d%97\/\">OEM\/ODM \u751f\u4ea7\u6307\u5357<\/a>.

How to Evaluate a Supplier for Your Project<\/h2>\n  <p>Keep a comparison sheet for each supplier with its legal entity, factory address, proposed model, documents reviewed, unanswered questions and quotation assumptions. Record specification and bill-of-materials revisions so changes remain traceable.<\/p>\n  <h3>Certificates and market requirements<\/h3>\n  <p>Start with the product\u2019s intended use, electrical and wireless features, claims and destination markets. Match compliance documents to the company, factory, scope and model they cover. ISO 13485 addresses a medical-device quality-management system; it does not approve a product. CE marking indicates conformity with applicable EU requirements, while FDA establishment registration and device listing identify registered operations and listed devices rather than FDA approval.<\/p>\n  <p>For US medical-device questions, review the <a href=\"https:\/\/www.fda.gov\/medical-devices\/how-study-and-market-your-device\/device-registration-and-listing\" target=\"_blank\" rel=\"noopener noreferrer\">FDA registration and listing information<\/a> and the <a href=\"https:\/\/www.fda.gov\/medical-devices\/postmarket-requirements-devices\/quality-management-system-regulation-qmsr\" target=\"_blank\" rel=\"noopener noreferrer\">FDA QMSR page<\/a>. For Great Britain, see the current <a href=\"https:\/\/www.gov.uk\/guidance\/placing-manufactured-goods-on-the-market-in-great-britain\" target=\"_blank\" rel=\"noopener noreferrer\">UK government guidance on placing manufactured goods on the market<\/a>. Confirm requirements for Northern Ireland separately.<\/p>\n  <h3>MOQ, quotes, and tooling<\/h3>\n  <p>Request a written quote for the exact SKU, order quantity, packaging, accessories, customization, and delivery terms. Ask suppliers to separate product price, tooling, testing, packaging, sample charges, and freight assumptions. MOQ can differ by stock model, color, packaging, custom housing, and new tooling; do not assume one figure applies to every order or supplier.<\/p>\n  <p>For custom work, define tooling ownership, maintenance, permitted use, change approval, and what happens when a project ends. Confirm in writing whether sample fees can be credited and which deliverables are included; do not rely on a general industry rule.<\/p>\n  <h3>Samples and production controls<\/h3>\n  <p>Record the sample\u2019s model, revision, materials, firmware and test conditions, then check it against your specification. Agree how incoming materials, assembly and finished goods will be inspected, and how the supplier will notify you of changes before production.<\/p>\n  <p>AQL means acceptance quality limit, a parameter used in a sampling plan. Agree the standard, inspection level, defect categories, sample size and acceptance and rejection numbers. Sampling does not guarantee that every unit is defect-free; specify separate controls for safety-critical defects.<\/p>\n  <h3>Communication, timing, and payment<\/h3>\n  <p>Assess how clearly the supplier answers technical questions and records decisions, changes and unresolved issues. Agree working contacts, response times and an escalation process. Allow for local time zones and daylight-saving changes when arranging calls.<\/p>\n  <p>Build the schedule around sample approval, tooling, component availability, production capacity, testing and shipment. Tie payment milestones to the agreed deliverables and documents, and check bank or platform protection terms, fees and dispute procedures before relying on them.<\/p>\n\n  <h2>5. Warning Signs During Supplier Review<\/h2>\n  <p>Follow up on inconsistencies before committing to an order. Ask for an explanation and supporting records so you can decide whether the concern has been resolved.<\/p>\n  <h3>Questions that need evidence<\/h3>\n  <ul>\n    <li><strong>Documents do not match the entity or model:<\/strong> Compare the certificate or test report with the named legal holder, site, scope, date, and product configuration.<\/li>\n    <li><strong>Unclear subcontracting:<\/strong> Ask which stages are performed at the stated site and which are assigned to outside providers.<\/li>\n    <li><strong>Sample and quote differ:<\/strong> Reconcile materials, accessories, packaging, firmware, and revision before comparing prices.<\/li>\n    <li><strong>Unexplained capacity or lead-time claims:<\/strong> Ask what assumptions, production steps, and current schedule support the estimate.<\/li>\n    <li><strong>Unspecified inspection terms:<\/strong> Put the inspection method, defect categories, sample size, and acceptance criteria in the project documents.<\/li>\n    <li><strong>Pressure to skip review:<\/strong> Keep time to verify identity, product claims, commercial terms, and market-specific responsibilities.<\/li>\n    <li><strong>Vague payment protection:<\/strong> Check the actual contract, platform rules, bank requirements, fees, and dispute process.<\/li>\n    <li><strong>Unclear material or design changes:<\/strong> Agree who may approve substitutions and how the approved version is recorded.<\/li>\n  <\/ul>\n\n  <figure class=\"relish-article-illustration\" data-concept=\"02\" style=\"margin:28px auto;width:100%;max-width:960px;\"><img loading=\"lazy\" class=\"wp-image-7901\" src=\"https:\/\/relish-tech.com\/wp-content\/uploads\/2026\/09\/electric-toothbrush-sample-engineering-discussion.webp\" alt=\"\u4e70\u5bb6\u901a\u8fc7\u89c6\u9891\u901a\u8bdd\u4e0e\u5de5\u7a0b\u5e08\u8ba8\u8bba\u7535\u52a8\u7259\u5237\u6837\u54c1\u7684\u63d2\u56fe\u3002.\" width=\"1536\" height=\"1024\" decoding=\"async\" style=\"display:block;width:100%;max-width:100%;height:auto;object-fit:contain;\" srcset=\"https:\/\/relish-tech.com\/wp-content\/uploads\/2026\/09\/electric-toothbrush-sample-engineering-discussion.webp 1536w, https:\/\/relish-tech.com\/wp-content\/uploads\/2026\/09\/electric-toothbrush-sample-engineering-discussion-300x200.webp 300w, https:\/\/relish-tech.com\/wp-content\/uploads\/2026\/09\/electric-toothbrush-sample-engineering-discussion-1024x683.webp 1024w, https:\/\/relish-tech.com\/wp-content\/uploads\/2026\/09\/electric-toothbrush-sample-engineering-discussion-768x512.webp 768w, https:\/\/relish-tech.com\/wp-content\/uploads\/2026\/09\/electric-toothbrush-sample-engineering-discussion-18x12.webp 18w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><figcaption style=\"margin-top:10px;font-size:14px;line-height:1.5;text-align:center;\">Use project documents and sample reviews to clarify technical and commercial questions.

Shenzhen and the Pearl River Delta: A Sourcing Context<\/h2>\n  <p>When reviewing suppliers in Shenzhen and the Pearl River Delta, ask how they source components and arrange tooling, testing, assembly and export shipments.
