Any factory that refuses all four should be crossed off your list.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide shows exactly what to check at each step \u2014 written from inside a factory, so you see both the legitimate process and the red flags that trading companies cannot hide.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Verify the Business Registration<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The company that signs your contract should be the same entity that owns the factory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What to check:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Business license<\/strong>\u00a0\u2014 Ask for a copy. Verify the registered address is a workshop location, not just a business office. The license in China shows the legal entity name, address, and business scope.<\/li>\n\n\n\n<li><strong>Company name match<\/strong>\u00a0\u2014 The name on the license, the contract, the invoices, and the bank account should all match. Discrepancies mean you may be dealing with a middleman billing under a different entity.<\/li>\n\n\n\n<li><strong>Export license<\/strong>\u00a0\u2014 A factory exporting directly needs import\/export rights. Ask which import-export license number is on their profile.<\/li>\n\n\n\n<li><strong>B2B platform profile age<\/strong>\u00a0\u2014 Alibaba or Made-in-China membership years are a rough proxy for operational history. A 2018 profile with 15 years of claimed experience is a contradiction.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Red flags:<\/strong>&nbsp;The business license address is in a commercial complex. The contract signer cannot produce a business license. The bank account name differs from the company name on the license.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Validate Certifications<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Certifications are the second verification layer. They are market-entry requirements \u2014 and verifiable documents.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What to check:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Certification<\/th><th>Market<\/th><th>How to Validate<\/th><\/tr><\/thead><tbody><tr><td>ISO 9001<\/td><td>Global<\/td><td>Verify the certificate number with the issuing body (e.g., TUV, SGS, BSI)<\/td><\/tr><tr><td>BSCI<\/td><td>Global (social compliance)<\/td><td>BSCI audits are searchable by audit ID in the BSCI database<\/td><\/tr><tr><td>ISO 14001<\/td><td>Global (environment)<\/td><td>Same as ISO 9001 \u2014 verify with the issuer<\/td><\/tr><tr><td>CE \/ UKCA<\/td><td>EU \/ UK<\/td><td>Check the declaration of conformity; CE marking without a valid DoC is a red flag<\/td><\/tr><tr><td>FDA<\/td><td>US<\/td><td>FDA registration is publicly searchable on the FDA website (device establishment registration)<\/td><\/tr><tr><td>RoHS \/ REACH<\/td><td>EU<\/td><td>Test reports from a recognized lab (SGS, TUV, Bureau Veritas) \u2014 check the lab name and report date<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What to request:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Copies of the certificates \u2014 not photos of a certificate wall<\/li>\n\n\n\n<li>The issuing body and certificate number for online verification<\/li>\n\n\n\n<li>Recent test reports \u2014 within 12 months \u2014 from a recognized third-party lab<\/li>\n\n\n\n<li>Confirmation of which certificates are in the factory&#8217;s own name<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Red flags:<\/strong>&nbsp;&#8220;Certificates available&#8221; but copies never arrive. Certificates in a different company name. Test reports older than 2 years. The factory cannot explain what each certificate covers.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Conduct an Audit (Remote or On-Site)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An audit is the highest-confidence verification. Two options:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Remote Audit (Video Call)<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Ask for a live, unscripted video walkthrough:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Production floor with running machines<\/li>\n\n\n\n<li>Material storage area (<a href=\"https:\/\/mellumeeyewear.com\/pt\/categoria-produto\/custom-acetate-sunglasses\/\" style=\"color:#0073aa; text-decoration:underline; font-weight:500;\">acetate<\/a> sheets, lenses, hardware)<\/li>\n\n\n\n<li>QC inspection station with actual tools<\/li>\n\n\n\n<li>Packaging area<\/li>\n\n\n\n<li>A random product pulled off the line and shown close-up<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A real factory can do this in 10 minutes. A trading company cannot \u2014 their &#8220;factory&#8221; is someone else&#8217;s.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">On-Site Audit (Recommended for Orders Above $10,000)<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">For significant orders, visit or hire an inspection agency for an on-site audit. What to check in person:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Check<\/th><th>What to Look For<\/th><\/tr><\/thead><tbody><tr><td>Production floor<\/td><td>Machines running, workers at stations \u2014 not a showroom<\/td><\/tr><tr><td>Equipment condition<\/td><td>Maintenance records, no rusted or idle machines<\/td><\/tr><tr><td>Material inventory<\/td><td>Stock of the acetate sheets, lenses, and hardware they claim to use<\/td><\/tr><tr><td>QC area<\/td><td>Magnification lamps, measuring tools, inspection stations<\/td><\/tr><tr><td>Mold library<\/td><td>Labeled storage, your competitor&#8217;s molds (or absence of them)<\/td><\/tr><tr><td>Worker environment<\/td><td>BSCI-compliant conditions \u2014 safety gear, no child labor signals<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Red flags:<\/strong>&nbsp;The &#8220;factory&#8221; is a small room with sample boards. Equipment is covered in dust. The tour skips the QC area. You are shown a video instead of a live walkthrough.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Verify Client References<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Any supplier can claim 500 clients. Verifiable references are the proof layer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What to check:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ask for 2-3 references from brands in your market and price segment \u2014 not just their biggest names<\/li>\n\n\n\n<li>Ask for a sample from a recent order, with the client&#8217;s market and product type described<\/li>\n\n\n\n<li>Check trade show presence: MIDO (Milan), Vision Expo (New York), CIOF (Shanghai) exhibitor directories are public<\/li>\n\n\n\n<li>Ask for their LinkedIn company page and check for a history of posts \u2014 a factory that posts factory floor content over years is likely real<\/li>\n\n\n\n<li>For Alibaba stores, check response rate, years, and review history<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What counts as verification:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A reference brand that replies to your email<\/li>\n\n\n\n<li>A sample product that matches the claimed order history<\/li>\n\n\n\n<li>An exhibitor listing at a real trade show<\/li>\n\n\n\n<li>A LinkedIn page with organic, dated factory content<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Red flags:<\/strong>&nbsp;References are always &#8220;confidential.&#8221; The &#8220;big clients&#8221; listed cannot be found on LinkedIn or the web. No trade show participation, ever.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">The Verification Scorecard<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Step<\/th><th>Pass (2 pts)<\/th><th>Partial (1 pt)<\/th><th>Fail (0 pts)<\/th><\/tr><\/thead><tbody><tr><td>1.

SGS, TUV, and Bureau Veritas pre-shipment inspections cost $200-500 and cover what a video call cannot \u2014 batch consistency, finish quality, and packaging compliance.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Can I trust Alibaba&#8217;s &#8220;Verified Supplier&#8221; badge?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">It is a starting point, not proof. Verification covers legal registration, not production capability or quality. Run all four steps regardless of badge status.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">What if the factory asks for 50% deposit before sampling?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Unusual. Industry standard is full or partial sample payment first, then a 30-50% production deposit. A demand for a large deposit before any sample is a red flag.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">How do I know if a factory is using child labor or unsafe conditions?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Check their BSCI audit status in the BSCI database. BSCI is a third-party social compliance audit. Factories with a valid BSCI audit have been inspected for worker conditions, safety, and ethical practices.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p
