\n

Wuhan is a relevant commercial location for international buyers sourcing from China.<\/strong> Wuhan is a major industrial center with substantial automotive, machinery, electronics and equipment manufacturing activity. A dispute involving a supplier in this market should be considered in light of both the contractual relationship and the practical characteristics of the local supply chain.<\/p>\n<\/section>\n

<\/p>\n

Introduction<\/h3>\n

OEM manufacturing allows overseas companies to have products manufactured in China according to their own designs, specifications, branding, and technical requirements.<\/p>\n

However, an OEM relationship can become legally complicated when the Chinese manufacturer delivers products that do not comply with the agreed specifications.<\/p>\n

The problem may involve:<\/p>\n

    \n
  • Incorrect dimensions;<\/li>\n
  • Different materials;<\/li>\n
  • Failure to meet technical parameters;<\/li>\n
  • Unauthorized design changes;<\/li>\n
  • Inferior components;<\/li>\n
  • Failure to follow approved samples;<\/li>\n
  • Incorrect packaging or labeling;<\/li>\n
  • Products that fail testing;<\/li>\n
  • Products that cannot be sold or used for their intended purpose.<\/li>\n<\/ul>\n

    A manufacturer\u2019s statement that the products are \u201csubstantially the same\u201d does not necessarily resolve the contractual issue. The first question is what the parties actually agreed the manufacturer was required to produce.<\/p>\n

    Chinese courts have addressed foreign-related commercial disputes involving disagreements over contractual components and technical specifications. In one recent case, the court used professional technical evaluation and mediation to help resolve a dispute concerning whether products complied with contractual specifications.<\/p>\n

    1. What Is an OEM Specification?<\/h3>\n

    An OEM specification is the set of technical, functional, design, material, and quality requirements that the manufacturer is expected to follow when producing a product for the buyer.<\/p>\n

    Depending on the transaction, specifications may appear in:<\/p>\n

      \n
    • OEM manufacturing agreements;<\/li>\n
    • Purchase orders;<\/li>\n
    • Technical specification sheets;<\/li>\n
    • Engineering drawings;<\/li>\n
    • Product datasheets;<\/li>\n
    • Approved samples;<\/li>\n
    • Bills of materials;<\/li>\n
    • Packaging specifications;<\/li>\n
    • Testing standards;<\/li>\n
    • Email correspondence;<\/li>\n
    • WeChat or other business communications.<\/li>\n<\/ul>\n

      The specifications do not necessarily have to appear in a single document.<\/p>\n

      A dispute may therefore arise when the manufacturer argues that one document controls while the buyer relies on another document, approved sample, or technical communication.<\/p>\n

      For this reason, OEM contracts should identify the documents that form part of the contractual specifications.<\/p>\n

      2. Common OEM Specification Failures<\/h3>\n

      2.1 Incorrect Dimensions<\/h3>\n

      The manufacturer may produce products with dimensions that differ from the agreed specifications.<\/p>\n

      For example:<\/p>\n

        \n
      • A component is too large to fit the buyer’s equipment;<\/li>\n
      • A product is manufactured with the wrong thickness;<\/li>\n
      • Packaging dimensions are incorrect;<\/li>\n
      • Parts do not fit together during assembly.<\/li>\n<\/ul>\n

        Even relatively small dimensional differences can be commercially significant when the product is designed for integration into another system.<\/p>\n

        2.2 Different Materials<\/h3>\n

        An overseas buyer may specify a particular:<\/p>\n

          \n
        • Grade of steel;<\/li>\n
        • Plastic material;<\/li>\n
        • Electronic component;<\/li>\n
        • Fabric;<\/li>\n
        • Wood;<\/li>\n
        • Coating;<\/li>\n
        • Chemical composition.<\/li>\n<\/ul>\n

          If the manufacturer substitutes another material without authorization, the resulting product may not comply with the OEM agreement.<\/p>\n

          The buyer should preserve documentation showing both the agreed material and the material actually used.<\/p>\n

          2.3 Failure to Meet Technical Parameters<\/h3>\n

          Technical specifications can include:<\/p>\n

            \n
          • Voltage;<\/li>\n
          • Power consumption;<\/li>\n
          • Capacity;<\/li>\n
          • Tolerance;<\/li>\n
          • Operating temperature;<\/li>\n
          • Load capacity;<\/li>\n
          • Performance requirements;<\/li>\n
          • Accuracy;<\/li>\n
          • Durability;<\/li>\n
          • Safety requirements.<\/li>\n<\/ul>\n

            The more important the parameter is to the product’s intended function, the more important it becomes to document the contractual requirement and the test results.<\/p>\n

            3. Approved Samples Can Be Important Evidence<\/h3>\n

            Many OEM disputes involve an approved pre-production sample.<\/p>\n

            The buyer may have approved a sample before mass production, but the manufacturer later delivers products that differ from it.<\/p>\n

            The buyer should preserve:<\/p>\n

              \n
            • Photographs of the approved sample;<\/li>\n
            • Sample specifications;<\/li>\n
            • Sample approval emails;<\/li>\n
            • Sample approval messages;<\/li>\n
            • Sample identification numbers;<\/li>\n
            • Production inspection records.<\/li>\n<\/ul>\n

              The OEM agreement should ideally state that mass-produced products must conform to the approved sample except for expressly permitted variations.<\/p>\n

              4. The Manufacturer May Argue That the Differences Are Minor<\/h3>\n

              A common dispute is whether the difference between the agreed specification and the delivered product is sufficiently significant to constitute a contractual breach.<\/p>\n

              The manufacturer may argue:<\/p>\n

              \u201cThe products are essentially the same.\u201d<\/p><\/blockquote>\n

              The buyer may argue:<\/p>\n

              \u201cThe products do not meet the specifications and cannot be used for their intended purpose.\u201d<\/p><\/blockquote>\n

              The legal analysis should therefore focus on the actual contractual obligations rather than simply whether the product looks similar.<\/p>\n

              A Supreme People’s Court case concerning commissioned development illustrates the importance of agreed technical specifications. The court considered whether specifically defined technical parameters had been satisfied and held that failure to meet certain agreed parameters could mean that the manufacturer\/developer had not completed the relevant contractual stage.<\/p>\n

              5. Testing and Inspection Evidence<\/h3>\n

              When an OEM specification dispute arises, independent testing can be particularly important.<\/p>\n

              Depending on the product, the buyer may consider obtaining:<\/p>\n

                \n
              • Laboratory test reports;<\/li>\n
              • Inspection reports;<\/li>\n
              • Engineering assessments;<\/li>\n
              • Photographic evidence;<\/li>\n
              • Measurement records;<\/li>\n
              • Comparison reports;<\/li>\n
              • Customer rejection records.<\/li>\n<\/ul>\n

                The testing method should correspond to the contractual specification whenever possible.<\/p>\n

                A report that merely states that the product is \u201cpoor quality\u201d may be less useful than a report showing:<\/p>\n

                Contractual requirement: X
                \nActual result: Y
                \nRequired tolerance: Z<\/p><\/blockquote>\n

                This type of comparison can make the dispute substantially easier to analyze.<\/p>\n

                6. Preserve the Chain of Evidence<\/h3>\n

                Overseas buyers should preserve evidence from the beginning of the transaction.<\/p>\n

                Important evidence may include:<\/p>\n

                Contractual Evidence<\/h3>\n
                  \n
                • OEM agreement;<\/li>\n
                • Purchase order;<\/li>\n
                • Quotation;<\/li>\n
                • Technical specification;<\/li>\n
                • Bill of materials;<\/li>\n
                • Drawings;<\/li>\n
                • Approved samples.<\/li>\n<\/ul>\n

                  Manufacturing Evidence<\/h3>\n
                    \n
                  • Production photographs;<\/li>\n
                  • Factory inspection reports;<\/li>\n
                  • Quality-control records;<\/li>\n
                  • Pre-shipment inspection;<\/li>\n
                  • Testing records.<\/li>\n<\/ul>\n

                    Delivery Evidence<\/h3>\n
                      \n
                    • Commercial invoice;<\/li>\n
                    • Packing list;<\/li>\n
                    • Bill of lading;<\/li>\n
                    • Delivery records;<\/li>\n
                    • Customs documents.<\/li>\n<\/ul>\n

                      Communication Evidence<\/h3>\n
                        \n
                      • Email;<\/li>\n
                      • WeChat;<\/li>\n
                      • WhatsApp;<\/li>\n
                      • Other business correspondence.<\/li>\n<\/ul>\n

                        Do not rely only on screenshots if the original electronic records can be preserved.<\/p>\n

                        7. What Should the Buyer Do After Discovering Non-Conforming Products?<\/h3>\n

                        The buyer should normally avoid immediately destroying, modifying, or returning the products without first considering the evidentiary consequences.<\/p>\n

                        A practical sequence may be:<\/p>\n

                          \n
                        1. Preserve the products and packaging;<\/li>\n
                        2. Photograph and record the defects;<\/li>\n
                        3. Compare the products against the contractual specifications;<\/li>\n
                        4. Obtain appropriate testing or inspection;<\/li>\n
                        5. Notify the manufacturer in writing;<\/li>\n
                        6. State the requested remedy;<\/li>\n
                        7. Preserve the manufacturer’s response.<\/li>\n<\/ol>\n

                          If the products are still in China, the buyer should also consider how the products will be inspected and preserved before shipment or disposal.<\/p>\n

                          8. Can the Buyer Demand Replacement?<\/h3>\n

                          Depending on the contract and applicable law, the buyer may seek an appropriate contractual remedy when the manufacturer fails to meet agreed specifications.<\/p>\n

                          Potential solutions may include:<\/p>\n

                            \n
                          • Replacement;<\/li>\n
                          • Re-manufacturing;<\/li>\n
                          • Repair;<\/li>\n
                          • Price reduction;<\/li>\n
                          • Refund;<\/li>\n
                          • Compensation for qualifying losses.<\/li>\n<\/ul>\n

                            The appropriate remedy depends on the contract, the seriousness of the non-conformity, the commercial purpose of the product, and the evidence available.<\/p>\n

                            9. Can the Buyer Refuse to Pay the Remaining Balance?<\/h3>\n

                            This is an issue that should be handled carefully.<\/p>\n

                            A buyer should not automatically assume that withholding the balance is legally safe merely because the goods have defects.<\/p>\n

                            The buyer should first review:<\/p>\n

                              \n
                            • Payment terms;<\/li>\n
                            • Inspection and acceptance provisions;<\/li>\n
                            • Contractual set-off provisions;<\/li>\n
                            • Non-conformity provisions;<\/li>\n
                            • Warranty provisions;<\/li>\n
                            • Applicable law;<\/li>\n
                            • Dispute-resolution clause.<\/li>\n<\/ul>\n

                              The buyer’s payment obligations and the manufacturer’s performance obligations need to be analyzed together.<\/p>\n

                              10. Can an Overseas Buyer Send a Lawyer’s Demand Letter?<\/h3>\n

                              Yes.<\/p>\n

                              A formal demand letter can set out:<\/p>\n

                                \n
                              • The contractual requirements;<\/li>\n
                              • The specific deviations;<\/li>\n
                              • The supporting evidence;<\/li>\n
                              • The legal basis of the claim;<\/li>\n
                              • The requested remedy;<\/li>\n
                              • A deadline for response;<\/li>\n
                              • The consequences of failing to resolve the dispute.<\/li>\n<\/ul>\n

                                For a Chinese manufacturer, a formal Chinese-language legal notice may also make it easier to communicate the seriousness of the dispute and establish a clear record of the buyer’s position.<\/p>\n

                                11. Can an Overseas Buyer Sue a Chinese Manufacturer?<\/h3>\n

                                Potentially, yes.<\/p>\n

                                The appropriate forum depends on the contract, dispute-resolution clause, applicable procedural rules, and other facts.<\/p>\n

                                The contract should be reviewed for:<\/p>\n

                                  \n
                                • Jurisdiction clause;<\/li>\n
                                • Arbitration clause;<\/li>\n
                                • Applicable law clause;<\/li>\n
                                • Place of performance;<\/li>\n
                                • Manufacturer’s registered location.<\/li>\n<\/ul>\n

                                  Chinese procedural law provides jurisdictional rules for certain foreign-related contract disputes and allows parties in foreign-related disputes, subject to applicable requirements, to agree in writing on a court with a practical connection to the dispute.<\/p>\n

                                  For international sales transactions, the applicable substantive law may also depend on the contract and the relevant international rules. The Supreme People’s Court has published cases in which the CISG was applied to international sales disputes between parties from contracting states where the parties had not excluded its application.<\/p>\n

                                  Therefore, an overseas buyer should not assume that Chinese domestic law automatically governs every OEM dispute.<\/p>\n

                                  12. Arbitration May Also Be an Option<\/h3>\n

                                  Some OEM contracts provide for arbitration rather than litigation.<\/p>\n

                                  Before starting proceedings, the buyer should determine:<\/p>\n

                                    \n
                                  • Whether a valid arbitration agreement exists;<\/li>\n
                                  • Which arbitration institution is specified;<\/li>\n
                                  • The seat or location of arbitration;<\/li>\n
                                  • The applicable procedural rules;<\/li>\n
                                  • The governing law;<\/li>\n
                                  • Whether interim measures are available.<\/li>\n<\/ul>\n

                                    The exact wording of the dispute-resolution clause can have a significant effect on the available legal strategy.<\/p>\n

                                    13. What If the Manufacturer Claims the Buyer Changed the Specifications?<\/h3>\n

                                    This is another common OEM dispute.<\/p>\n

                                    The manufacturer may claim that:<\/p>\n

                                      \n
                                    • The buyer changed the design;<\/li>\n
                                    • The buyer approved the revised specifications;<\/li>\n
                                    • The buyer accepted a sample;<\/li>\n
                                    • The buyer’s later instructions superseded the original agreement.<\/li>\n<\/ul>\n

                                      The buyer should therefore preserve the chronology of communications.<\/p>\n

                                      A useful record may look like:<\/p>\n

                                      Original Specification\r\n        \u2193\r\nManufacturer Confirmation\r\n        \u2193\r\nApproved Sample\r\n        \u2193\r\nProduction\r\n        \u2193\r\nInspection\r\n        \u2193\r\nDiscovered Deviation\r\n<\/code><\/pre>\n
                                      This can help establish which specification was actually applicable when production occurred.<\/p>\n
                                      14. How to Reduce OEM Specification Disputes<\/h3>\n
                                      Foreign buyers can reduce risk by making the OEM agreement more specific.<\/p>\n
                                      The contract should ideally identify:<\/p>\n
                                      Product Specifications<\/h3>\n
                                        \n
                                      • Exact dimensions;<\/li>\n

                                              Evidence<\/h3>\n
                                              The agreement should also identify which technical documents and approved samples form part of the contract.<\/p>\n
                                              Conclusion<\/h3>\n
                                              When a Chinese OEM manufacturer fails to meet agreed product specifications, the central issue is usually not simply whether the product has a \u201cquality problem.\u201d<\/p>\n
                                              The more important questions are:<\/p>\n
                                                \n
                                              1. What specifications did the parties actually agree upon?<\/li>\n
                                              2. Which documents form part of the contract?<\/li>\n
                                              3. Does the delivered product comply with those requirements?<\/li>\n
                                              4. Can the buyer prove the non-conformity?<\/li>\n
                                              5. What remedy does the contract provide?<\/li>\n
                                              6. Which court or arbitration institution has jurisdiction?<\/li>\n<\/ol>\n
                                                For overseas buyers, preserving the original specifications, approved samples, inspection records, and communications can be critical.<\/p>\n
                                                A specification dispute can often be addressed through negotiation and a formal legal demand before litigation. If the dispute cannot be resolved, the contract and evidence should be reviewed to determine whether litigation or arbitration is appropriate.<\/p>\n
                                                <\/p>\n

                                                Local Supply Chain Risks in Wuhan<\/h3>\n
                                                International buyers dealing with Wuhan companies may be sourcing products or services connected with automotive, machinery, electronics and industrial equipment. Typical issues may include equipment quality disputes, delivery disputes, OEM disputes, warranty claims and payment disputes. For machinery, automotive, electronics and equipment transactions, buyers should pay particular attention to technical specifications, acceptance criteria, warranty terms, delivery milestones and the entity responsible for performance.<\/p>\n
                                                Wuhan is located in Hubei and is supported by a diversified industrial base and extensive supply chains serving central China. For cross-border transactions, this background can be useful when assessing supplier verification, contract enforcement and dispute-resolution options.<\/p>\n<\/section>\n
                                                <\/p>\n
                                                <\/p>\n
                                                \n
                                                Resolving a Supplier Dispute in Wuhan<\/h3>\n
                                                Where a commercial dispute has developed, an overseas buyer should avoid relying solely on informal communications. Reviewing the contract, identifying the correct legal entity, preserving documentary evidence and assessing the available dispute-resolution mechanism are usually important before deciding how to proceed.<\/p>\n
                                                The appropriate legal strategy depends on the specific transaction, the supplier\u2019s conduct, the evidence available and the applicable legal framework.<\/p>\n<\/section>\n
