Sourcing Flat washer from Zhejiang Ruian Zhufeng Standard Parts Co., Ltd - China Import Guide
Verify the exact material composition of each washer type before ordering, especially for brass and nylon. Request material certificates for stainless steel to confirm grade, and ensure nylon washers are acetal homopolymer, not copolymer. Confirm that all dimensions meet DIN125 tolerances using a certified inspection report. Do not assume standard compliance without documentation.
Confirm Incoterms, lead time, and packaging with the supplier. FOB Ningbo is typical, but lead time can range from 20 to 40 days depending on material stock. MOQ is not stated and varies by size. Payment terms are usually 30% advance, balance against shipping documents. Request a pre-shipment inspection if the order exceeds 10,000 pieces.
Perform incoming inspection using a micrometer for inner and outer diameter, a thickness gauge, and a visual check for surface defects. For nylon washers, test for brittleness by bending a sample. For brass, use a magnet to confirm non-ferrous properties. Retain samples for each batch and request a Certificate of Conformity with lot number traceability. Reject cartons with moisture damage or mixed sizes.
