Q: Can samples be provided before mass production?

Certainly. JinHai can provide you with 1-5 samples.Is there a charge for samples?JinHai offers two options for your consideration.Simple, low-value samples: If you clearly express your intention to collaborate with Jinhai (typically requiring detailed drawings, specific quantity requirements, and a delivery schedule), we will charge 60%-80% of the standard sample price. We commit to deducting this sample fee from the order payment when subsequent bulk orders are placed.Complex, high-value samples: For products involving hundreds of circuits, specialized connectors, or expensive shielding layers, we charge standard sample fees. However, we commit to refunding the sample cost if your subsequent order exceeds 10 times the sample value.Sample Lead TimeUpon receiving your sample request, JinHai will complete sample production within 1-3 weeks and ship it to your location via international express delivery.

Q: How to Protect Wiring Harnesses During Transportation?

Moisture Prevention Measures: At JinHai, wiring harnesses are packaged in cardboard boxes.Internal Moisture Protection: Two methods are used—PE bags or aluminum foil bags (specific method determined by customer specification or provision)—with three desiccant packets per box for additional moisture control.External Moisture Protection: After final packaging, products are placed on pallets for shipment. Prior to dispatch, goods on pallets receive secondary protection with stretch wrap.Shock Absorption Solutions:During transit, wiring harnesses experience vibrations and jostling. To prevent damage to critical connectors, JinHai offers enhanced shock absorption solutions:Wrapping entire harnesses in bubble wrap for protection;Using custom-shaped EVA foam to wrap harnesses or as padding/separators;Employ custom-molded foam liners specifically designed for high-value wiring harnesses.All packaging methods listed above are provided by JinHai. Should customers specify alternative packaging requirements, we will strictly adhere to those instructions.
