Contract Dispute Over Defective Valves Leads to 2.6 Million Yuan Claim Dismissed

Contract Dispute Over Defective Valves Leads to 2.6 Million Yuan Claim Dismissed

Case Overview

A Chinese company sought 2.6 million yuan in damages from a valve supplier, alleging that incorrectly marked directional arrows on three-way valves caused production delays at a petrochemical facility. The court dismissed the claim, ruling that the buyer failed to provide sufficient evidence linking the valve installation error to the claimed losses. The judgment highlights the critical importance of proof in commercial disputes.

Case Background and Facts

In December 2008, a plastics company based in Eastern China entered into a sales contract with an instrument manufacturer from the same region. The buyer purchased various models of control valves for a 500,000-ton-per-year cracking unit designed to produce light olefins. The total contract price was 2.6 million yuan.

The seller delivered the valves in two batches in June and July 2009. The buyer installed the equipment, and the seller completed on-site commissioning before November 10, 2009. During this commissioning process, the seller discovered that the directional arrows on three specific three-way mixing control valves were incorrectly marked on the valve bodies. The seller corrected the arrow orientation during the commissioning phase.

The buyer’s cracking unit began full commercial production on November 16, 2009. The buyer later claimed that the arrow misdirection prevented normal operation until repairs were made on November 25, 2009, resulting in significant economic losses.

In July 2010, the seller sued the buyer for unpaid balance of the purchase price. The parties reached a settlement in August 2010, with the buyer agreeing to pay the remaining 1,127,465 yuan. The buyer did not raise any quality claims during that proceeding.

Court Proceedings and Evidence

The buyer initiated this separate lawsuit seeking 2.6 million yuan in damages. To support its claim, the buyer submitted several pieces of evidence: the original sales contract and technical specifications, an environmental protection bureau document confirming the production start date, internal maintenance work tickets, a construction report and photographs showing the valve reorientation, and a self-prepared economic loss assessment report.

The seller disputed the buyer’s claims. It argued that the arrow error was discovered and corrected during commissioning, before the production unit started. The seller further stated it never received any claim notice from the buyer, including during the earlier payment dispute. The seller produced copies of field service reports to support its position.

The court examined the evidence carefully. The buyer’s maintenance work tickets and construction report were issued by a third-party company, but the court noted that the identity of the individuals who signed these documents could not be verified. The construction report bore a stamp from a project department of a company whose legal existence was not properly established. The court found these documents insufficient to prove that the valves were adjusted only after production had started.

The loss assessment report was prepared solely by the buyer and was not acknowledged by the seller, so the court did not accept it as reliable evidence.

Court Findings and Judgment

The court held that under Chinese civil procedure law, a party asserting a claim bears the burden of proof. The buyer failed to provide credible evidence demonstrating that the valve adjustment occurred after production began or that the alleged arrow error caused the claimed losses.

The court noted that the seller had corrected the arrow marking during the commissioning phase, before the equipment entered commercial operation. The buyer’s argument that the error prevented normal production conflicted with the timeline established by the evidence.

The court dismissed the buyer’s lawsuit in its entirety. The buyer was ordered to bear the court costs of 18,800 yuan.

Key Legal Principles

The case applies the fundamental principle of burden of proof in civil litigation. The party who asserts a fact must provide sufficient evidence to establish that fact. When the evidence is insufficient or unreliable, the court will not support the claim.

The court also applied the principle that internal documents and self-prepared reports, without independent verification or corroboration, carry limited evidentiary weight.

Practical Insights

This case demonstrates that businesses must maintain thorough documentation when pursuing claims for contractual damages. A buyer who discovers a defect should document the issue promptly, obtain independent verification, and preserve evidence showing how the defect caused specific losses.

The case also illustrates the importance of raising claims in a timely manner. The buyer’s failure to mention the quality issue during the earlier payment dispute weakened its position.

Parties to commercial contracts should ensure that commissioning and acceptance procedures are clearly documented and signed off by both sides at the time of completion.
