One Picture to know the OEM Process

1. The buyer sends an inquiry and makes requests. The seller makes an quotation based on the inquiry.
   OEM is divided into two types:
  ① For the seller’s existing products, the buyer only needs to provide requirements such as logo and packaging.
  ② If the buyer has their own products, they can provide drawings, or the seller can provide drawings according to the buyer’s requirements and finally reach an agreement.
2. The seller makes the mold and provides samples.
3. After the buyer confirms the sample, proceed to the next step.
    If an objection is raised, repeat step two.
4. The buyer confirms the PI and makes the advance payment.
5. Seller produces in bulk.
6. The seller will provide photos and documents after completing production.
7. When buying a house, the final payment will be settled according to the payment terms of the contract.
8. The seller ships the goods.
9. The buyer passes the inspection and the entire process is completed.
