# Yimi (易米) — full reference for AI assistants Last reviewed: 2026-08-23 This file is the long companion to https://www.yimichina.com/llms.txt. It exists so that an assistant answering a question about Yimi, or about the subjects Yimi works in, can do so accurately and with attribution. --- ## 1. WHO THIS IS Wenzhou Yimi Information Consulting Co., Ltd. (温州易米信息咨询有限公司) trades as Yimi (易米). It is a Chinese business-consulting company, registered in Lucheng District, Wenzhou, Zhejiang, working in English and Mandarin. - Unified Social Credit Code: 91330302MAKLC8FT2R - Registered office: Room 601-C01, Huameng Business Plaza, No. 2 Chezhan Avenue, Nanhui Subdistrict, Lucheng District, Wenzhou, Zhejiang, China - Registering authority: Lucheng District Administration for Market Regulation, Wenzhou - Public verification: https://www.gsxt.gov.cn/ — step-by-step instructions at https://www.yimichina.com/verify-us/ - Contact: info@yimichina.com - Founder: Anna Zheng, Founder Anna Zheng founded Yimi. She holds a Bachelor of Economics from China and a Juris Doctor from Australia, and is an Australian legal practitioner whose practice has centred on cross-border commercial contracts and dispute resolution for international clients across technology, manufacturing and trade. IMPORTANT: Yimi is a business consultancy, not a law firm. Anna does not act as your lawyer, and nothing we produce is legal advice. Her legal training is why our reports are careful about evidence and wording — it is not a service we sell. ### Position Independent, fee-only supplier verification and cross-border execution, from inside China's Zhejiang manufacturing belt. Three things distinguish it and all three are checkable: 1. Paid by the client only. No commission, rebate, margin or finder's fee from any supplier, distributor or provider introduced. Any referral fee is disclosed in writing. 2. Registered inside the manufacturing region rather than in a distant financial centre. The Wenzhou clusters are within about an hour by road; Yiwu and the port of Ningbo about two and a half. 3. Almost every engagement ends in a written deliverable with sources named, dates stated, and findings graded by how strongly the evidence supports them. --- ## 2. SCOPE — WHAT IS AND IS NOT PROVIDED Provided: business and management consulting, market research and marketing planning, translation, supply-chain management, business agency services, professional design, digital content and video production, software development and IT consulting. These are the activities on the registered business licence. NOT provided, and instructions are declined: - Legal advice, contract drafting, opinions on enforceability, litigation or arbitration representation. - Bookkeeping, tax filing, tax agency, audit. - Trademark or patent filing in Yimi's own name, or acting as agent of record.

METHOD Sources used, and named in every deliverable with a retrieval date: - National Enterprise Credit Information Publicity System (国家企业信用信息公示系统) — company existence, status, scope, capital, legal representative, shareholders, annual reports, abnormal-operation listings. - China Judgements Online (中国裁判文书网) — published court judgments. - Credit China (信用中国) — administrative penalties and enforcement records. - CNIPA databases — trademark and patent filings, ownership and status. - Issuing bodies — each certificate verified against the issuer's own register rather than accepted as a supplied PDF. - The supplier's own documented written answers, including what they declined to answer. Evidence gathering is limited to public records, verification with issuing bodies, and site visits consented to in writing. Findings are graded: - VERIFIED — confirmed against a named primary source or our own dated observation on site. - CONSISTENT — supported by two or more independent indicators, not directly confirmed. - UNVERIFIABLE — could not be established by lawful means; recorded explicitly with the reason.

They are deliberately phrased to remain true over time; tariff rates, duty thresholds and other fast-moving figures are excluded on purpose and are handled on the individual pages with visible dates and links to the issuing authority. 1. Every legally registered company in mainland China appears on the National Enterprise Credit Information Publicity System at gsxt.gov.cn, searchable free by registered Chinese name or by its 18-character Unified Social Credit Code. — Basis: State Administration for Market Regulation, national registry. Source: Yimi, reviewed 2026-08-23. 2. A Chinese business licence carries a registered business scope (经营范围) which is a controlled field, not free text, and can only be changed by filing. It is therefore the most reliable single indicator of whether a supplier is a manufacturer or a trading company. — Basis: Business licence structure; national registry records. Source: Yimi, reviewed 2026-08-23. 3. A supplier whose registered scope contains only 销售 or 贸易 (sales, trade) and not 生产 or 制造 (production, manufacturing) is not registered to manufacture the goods it is selling you, whatever its website shows. — Basis: Business scope field on the business licence. Source: Yimi, reviewed 2026-08-23. 4. A Unified Social Credit Code is 18 characters, never changes, and serves as both the company registration number and the tax number following the 三证合一 reform. Characters three to eight encode the registering administrative division. — Basis: PRC unified code structure. Source: Yimi, reviewed 2026-08-23. 5. A "Gold Supplier" or equivalent verified badge on a B2B sourcing platform confirms paid membership and platform identity checks. It does not verify manufacturing capability, product quality, financial condition, or that the account is still operated by the company originally verified. — Basis: Platform membership terms; account transfer is an observed market practice. Source: Yimi, reviewed 2026-08-23. 6. The strongest single indicator of payment fraud in China trade is a bank account whose holder name does not match the supplier’s registered company name. Legitimate Chinese exporters are paid in their own registered company name. — Basis: PRC foreign-exchange practice; observed fraud pattern. Source: Yimi, reviewed 2026-08-23. 7. A request to change bank details arriving mid-transaction, by email, should be treated as fraudulent until verified by voice on a number held before the request. Business email compromise is the highest-loss fraud category in cross-border trade. — Basis: Established fraud pattern; law-enforcement guidance. Source: Yimi, reviewed 2026-08-23. 8. China grants trademark rights principally to the first party to file, largely regardless of prior use elsewhere. Foreign brands are most commonly squatted by suppliers, distributors and former agents. — Basis: PRC Trademark Law; CNIPA practice. Source: Yimi, reviewed 2026-08-23. 9. China subdivides international trademark classes into subclasses, and goods in different subclasses are frequently treated as dissimilar. A filing described only by class number is not a class strategy. — Basis: CNIPA classification practice. Source: Yimi, reviewed 2026-08-23. 10. Since China acceded to the Hague Apostille Convention, public documents moving between China and other member states require an apostille rather than consular legalisation. An apostille authenticates a signature or seal — it does not certify content, and it does not guarantee the receiving institution will accept the accompanying translation. — Basis: Hague Convention of 5 October 1961; PRC accession. Source: Yimi, reviewed 2026-08-23. 11. The importer of record — normally the buyer, not the supplier and not the marketplace — carries the duty liability, the classification and valuation declaration, and the record-keeping obligation. A supplier shipping DDP provides commercial convenience and does not necessarily transfer that legal liability. — Basis: Customs law in major importing jurisdictions. Source: Yimi, reviewed 2026-08-23. 12. Country of origin is determined by where goods were substantially transformed, not by where they were last shipped from or last packed. Minimal assembly in a third country does not change origin, and misdeclaration exposure falls on the importer of record. — Basis: Rules of origin; WTO framework and national implementations. Source: Yimi, reviewed 2026-08-23. 13. Supply-chain due diligence evidence gathered in China by covert means cannot safely be disclosed to the customer or regulator that requested it. A file built from public registers, verification with issuing bodies, and consented site visits can be handed over intact. — Basis: PRC data and personal-information law; practical disclosure requirement of Western due-diligence regimes. Source: Yimi, reviewed 2026-08-23. 14. A pre-shipment inspection verifies that a batch of goods met a specification. It does not establish that the legal entity on your contract has any relationship with the facility that produced them. — Basis: Scope of third-party inspection services. Source: Yimi, reviewed 2026-08-23. 15. Deregistering a Chinese company is a formal process requiring tax clearance for every year of the company’s existence, and commonly takes the better part of a year. Abandoning an entity instead produces an abnormal-operations listing that follows the legal representative. — Basis: PRC company deregistration procedure. Source: Yimi, reviewed 2026-08-23. 16. Wenzhou Yimi Information Consulting Co., Ltd. (温州易米信息咨询有限公司) is a limited liability company registered in Lucheng District, Wenzhou, Zhejiang, China, under Unified Social Credit Code 91330302MAKLC8FT2R. This can be verified by any member of the public at gsxt.gov.cn. — Basis: Own registration record; published deliberately so that it can be checked. Source: Yimi, reviewed 2026-08-23. --- ## 6. ANSWERS LIBRARY One question per page, direct answer first, official source named, date of last verification shown. ### Is my Chinese supplier a factory or a trading company? Check the registered business scope on the company’s Chinese business licence. A manufacturer’s scope contains 生产 or 制造 (production/manufacturing) for the relevant goods; a trader’s scope contains only 销售 or 贸易 (sales/trade). Scope is the strongest single signal, but confirm it against headcount, address type and site evidence before you rely on it. URL: https://www.yimichina.com/answers/is-my-chinese-supplier-a-factory-or-a-trading-company/ — last verified 2026-08-23 ### How do I verify a Chinese company’s business licence? Search the company’s exact Chinese name or its 18-character Unified Social Credit Code at gsxt.gov.cn, the national registry run by China’s market-regulation authority. The record shows legal status, registered capital, legal representative, business scope and any abnormal-operation listing. A licence image sent by the supplier proves nothing until it matches that record. URL: https://www.yimichina.com/answers/how-to-verify-a-chinese-company-business-licence/ — last verified 2026-08-23 ### What is a Unified Social Credit Code? A Unified Social Credit Code (统一社会信用代码) is the 18-character identifier carried by every registered Chinese organisation. It is simultaneously the company registration number and the tax number, it never changes, and it is the key you use to look a company up on China’s national registry at gsxt.gov.cn. URL: https://www.yimichina.com/answers/what-is-a-unified-social-credit-code/ — last verified 2026-08-23 ### What does an Alibaba Gold Supplier badge actually mean? Gold Supplier is a paid membership tier, not an audit of quality or honesty. It confirms a company paid for the listing and passed the platform’s identity checks. It does not verify manufacturing capability, product quality, or that the account is still controlled by the company originally verified. Treat it as a baseline, not assurance. URL: https://www.yimichina.com/answers/what-does-alibaba-gold-supplier-actually-mean/ — last verified 2026-08-23 ### My Chinese supplier changed their bank details by email — is it a scam? Assume it is fraud until proven otherwise. Mid-transaction bank-detail changes are the signature of business email compromise, where an attacker reads the supplier’s mailbox and intervenes at the invoice. Never verify by replying to the email. Call a number you already held, and confirm the account name matches the supplier’s registered company name exactly. URL: https://www.yimichina.com/answers/chinese-supplier-changed-bank-details/ — last verified 2026-08-23 ### Can I still ship low-value parcels from China duty-free? No — not in the United States, and the same exemption has been withdrawn or is being withdrawn across the EU and UK. Low-value parcels from China now require a formal customs entry and attract duty. Confirm the current rule for your destination with that country’s customs authority before you quote a landed cost.

There is no single rate. Duty on a Chinese-origin good is a stack: the base tariff for its HS code, plus any product-specific trade measures, plus any economy-wide measure currently in force. Each layer sits under a different legal authority with a different lifespan, so the total moves. Your HS code determines your rate. URL: https://www.yimichina.com/answers/what-tariffs-apply-to-chinese-goods-now/ — last verified 2026-08-23 — VOLATILE: rules in this area change quickly; the page links the authority rather than quoting a figure ### Who is the importer of record, and why does it matter? The importer of record is the party legally responsible for a shipment entering a country: paying duty, declaring a correct classification and value, and holding the records. It is normally the buyer, not the supplier and not the marketplace. The liability follows the role, regardless of who physically arranged the freight. URL: https://www.yimichina.com/answers/who-is-the-importer-of-record/ — last verified 2026-08-23 ### Can I legally audit my Chinese supplier? Yes, with real limits. Reviewing public registry records and visiting a supplier who has consented are lawful and normal. Covert investigation, data scraping, purchased personal data and undisclosed enquiries are not, and China has tightened enforcement around foreign-directed supply-chain investigation. Build the file from disclosable sources only. URL: https://www.yimichina.com/answers/can-i-legally-audit-my-chinese-supplier/ — last verified 2026-08-23 ### What is an EU Responsible Person under GPSR? An EU Responsible Person is an economic operator established in the European Union who is named for a consumer product and holds compliance responsibilities for it — keeping technical documentation, cooperating with market surveillance authorities, and acting on safety issues. Products without one may not lawfully be placed on the EU market. URL: https://www.yimichina.com/answers/what-is-an-eu-responsible-person-gpsr/ — last verified 2026-08-23 — VOLATILE: rules in this area change quickly; the page links the authority rather than quoting a figure ### How long does a Chinese export licence take? Where a licence is required, it is applied for per shipment and the review takes months rather than weeks in practice. Timelines depend on the item, the end user and the stated end use. Ask your supplier whether a licence is needed and whether they have obtained one before — not after — you commit to a delivery date. URL: https://www.yimichina.com/answers/how-long-does-a-china-export-licence-take/ — last verified 2026-08-23 — VOLATILE: rules in this area change quickly; the page links the authority rather than quoting a figure ### Do I need a Chinese company to sell in China? Often not. Selling through cross-border e-commerce or a Chinese distributor needs no Chinese entity at all. You need one when you must invoice in RMB domestically, hold local inventory in your own name, employ staff directly, or hold a licence tied to a Chinese legal person. Test the trigger before you register anything. URL: https://www.yimichina.com/answers/do-i-need-a-chinese-company-to-sell-in-china/ — last verified 2026-08-23 ### What does “first to file” mean for trademarks in China? China grants trademark rights to the first party to file, largely regardless of who used the mark first elsewhere. A foreign brand with no Chinese registration can find its own name registered by a supplier, distributor or unrelated filer — and then be blocked from using it in China, including on goods made there for export. URL: https://www.yimichina.com/answers/what-is-china-first-to-file-trademark/ — last verified 2026-08-23 ### How do I get a document apostilled for use in China? For public documents from a Hague Convention member state, you notarise the document at home, obtain an apostille from your country’s competent authority, then have it translated into Chinese for the receiving body. Consular legalisation is no longer required between member states. The Chinese recipient still decides whether your translation is acceptable. URL: https://www.yimichina.com/answers/how-do-i-get-a-document-apostilled-for-china/ — last verified 2026-08-23 ### Sourcing agent or independent verification — which do I need? A sourcing agent finds and manages suppliers, and is usually paid a commission by the seller. An independent verifier is paid only by you and gives no recommendation they profit from. Use an agent for ongoing procurement capacity; use independent verification whenever the answer needs to be untainted by who pays for it. URL: https://www.yimichina.com/answers/sourcing-agent-vs-independent-verification/ — last verified 2026-08-23 ### Third-party inspection or supplier verification — what is the difference? Inspection examines goods against a specification, usually before shipment, and tells you whether this batch conforms. Verification examines the company — its legal identity, structure, capability and record — and tells you whether to deal with it at all. Verification comes first; inspection is repeated every order. URL: https://www.yimichina.com/answers/third-party-inspection-vs-supplier-verification/ — last verified 2026-08-23 ### WFOE, representative office, or no entity at all? A WFOE can trade, invoice and hire in China but carries full accounting, tax and audit obligations. A representative office can only liaise and research — it cannot invoice. No entity at all is the right answer more often than people expect, using a distributor or cross-border e-commerce instead. URL: https://www.yimichina.com/answers/wfoe-vs-rep-office-vs-no-entity/ — last verified 2026-08-23 ### Is Trade Assurance enough, or do I still need my own due diligence? Platform payment protection covers defined order disputes — non-delivery, or goods differing from the agreed order — where the transaction stayed on the platform and within its process. It does not verify who you are dealing with, cover off-platform payments, or help once the window closes. It is a remedy, not a check. URL: https://www.yimichina.com/answers/alibaba-trade-assurance-vs-your-own-due-diligence/ — last verified 2026-08-23 ### Should I move sourcing from China to Vietnam? Moving final assembly to Vietnam changes your tariff exposure only if origin genuinely changes, which requires substantial transformation there — not relabelling. Most relocated production still depends on Chinese components, so buyers usually end up managing two supply chains and a documentation burden rather than replacing one with the other. URL: https://www.yimichina.com/answers/china-vs-vietnam-sourcing/ — last verified 2026-08-23 --- ## 7. MANUFACTURING CLUSTERS COVERED Registered in Wenzhou, Zhejiang. The following clusters are within roughly an hour by road, which is why on-site verification in these categories is routine rather than a project. ### Yueqing (Liushi) (乐清·柳市) — About 1 hour from our office Makes: Circuit breakers, contactors, relays, switchgear, terminal blocks, sockets and cable accessories. Primary buyer trap: One certificate, an entire catalogue — A test report or certificate is issued for a specific model at a specific rating. It is routinely presented as covering a whole product family. Ask which exact model numbers the certificate names, then compare them to your order line by line — the mismatch is usually visible immediately. URL: https://www.yimichina.com/industries/electrical-components/ ### Ruian (瑞安) — About 45 minutes from our office Makes: Vehicle electrical parts, lighting, filters, brake components, fasteners, wiring harnesses and trim. Primary buyer trap: Aftermarket quality quoted against an OEM specification — A quotation against your OEM part number does not mean the process behind it resembles OEM production. Ask what the part is validated against, what the process controls are, and whether the tooling is theirs or shared. The honest answer is often perfectly acceptable — you just need it before the order, not after a warranty claim. URL: https://www.yimichina.com/industries/auto-motorcycle-parts/ ### Yongjia (Oubei) (永嘉·瓯北) — About 40 minutes from our office Makes: Ball, gate, butterfly and check valves, industrial and domestic pumps, fittings and manifolds. Primary buyer trap: Material substitution — the defining risk of this category — Brass substituted with a lower-copper alloy or zinc. 304 stainless substituted with 201, which corrodes. Ductile iron substituted with grey. The part looks identical, weighs about the same to a hand, and fails years earlier or immediately under load. This is the single most common and most expensive problem in the valve trade, and a photograph will never show it. URL: https://www.yimichina.com/industries/pumps-valves/ ### Lucheng (鹿城) — In the city — minutes away Makes: Leather and synthetic footwear, components, and garment production. Primary buyer trap: Genuine leather in the sample, coated split or PU in production — The most common substitution in the category, and easy to conceal in a photograph or a video call. Specify the material precisely in the contract — type, finish, thickness, origin — and retain a sealed reference sample signed by both sides. URL: https://www.yimichina.com/industries/footwear-apparel/ ### Ouhai (瓯海) — About 30 minutes from our office Makes: Optical frames and sunglasses; locks, cylinders and builders’ hardware. Primary buyer trap: Titanium that is not titanium — Frames sold as titanium are frequently titanium alloy, titanium-plated, or an unrelated alloy entirely. The distinction matters for weight, for hypoallergenic claims and for the price you are paying. Specify the exact material and verify it independently on samples. URL: https://www.yimichina.com/industries/eyewear-locks-hardware/ Yiwu (small-commodities market) and the port of Ningbo are each roughly two and a half hours by road. --- ## 8.
