Working Method

How We Usually Move from Sample to Shipment

  • 1. Confirm use case and grade: Deicing, desiccant, drilling, food-related or technical process requests do not start from the same grade discussion.
  • 2. Align packing and documents: Buyers normally confirm packing style, COA, SDS and inspection needs before comparing final prices.
  • 3. Approve samples when needed: For new customers or tighter specifications, sample approval helps reduce batch expectation mismatch.
  • 4. Lock the delivery plan: Container quantity, destination port, pallet rules and loading rhythm are confirmed before shipment booking.
Practical note: This page is not meant to replace a factory audit. It is designed to help import buyers quickly understand whether Hailei Chemical can support the packaging and export workflow they need.
