Professional Manufacturer Of Hoses And Accessories

***The customer purchased 18,000 rolls of DN65×25m fire hoses with a working pressure of 1.6MPa from the supplier, shipped in 3 40HQ containers to *** port. After arrival, the customer conducted AQL sampling inspection and found that 6,800 rolls had issues including poor inner liner adhesion, local leakage, and burst pressure below contractual requirements, involving 3 production batches. The customer suspended warehousing and requested full batch return/exchange and compensation for port demurrage fees.

The supplier initiated an 8D quality investigation within 48 hours and, jointly with the third-party testing agency SGS, re-inspected the retained samples and customer-sealed samples, confirming that the batch-wide poor adhesion was caused by temperature fluctuations in the liner extrusion process. After consultation with *** customer: 1) The 2,600 rolls not yet customs-cleared will be returned to the factory; 2) The 4,200 rolls already in storage will be consolidated at *** warehouse, and the supplier will entrust a local partner to collect and dispose of them; 3) The supplier will expedite production and replenish 6,800 rolls of qualified products of the same specification in two batches; 4) The supplier will bear the difference in ocean freight for the return and replenishment, the demurrage charges at *** port, the collection and disposal fees, and the third-party testing fees; 5) The factory will isolate and rework the affected batches, tighten full inspection of burst pressure, leakage, and adhesion strength, and the replenishment containers will be accompanied by batch test reports and 8D reports; 6) The first batch of 3,000 rolls will be shipped by ***, and the remaining 3,800 rolls will be shipped on the next voyage.
