In the progressive society, there are more and more places to use the letter of commitment. In writing, the commitment letter has certain writing norms. There is always nothing to write when writing a commitment letter? The following is the product quality assurance commitment letter I collected for you. Welcome to read the collection.

We guarantee that the contract goods provided are brand-new and unused. We guarantee the safe and reliable operation of the contract goods under the conditions of correct installation and normal operation. During the quality guarantee period, if the contract goods provided by us are found to be defective and inconsistent with the contract, the buyer may lodge a claim with us. We repair, replace or compensate the buyer's losses according to the buyer's requirements. If replacement is needed, we will replace it with qualified and high-quality products in time. All expenses arising therefrom will be borne by us. If we have any objection to the claim, we will put forward it in writing within 7 days after receiving the buyer's claim notice, otherwise it will be regarded as acknowledging the buyer's claim. We appoint the project manager in charge of this project to coordinate the seller's work in the whole process of the project, such as project progress, design and manufacturing, drawings and documents, manufacturing confirmation, packaging and transportation, on-site installation, debugging and acceptance.
We strictly follow the quality assurance system in the whole production process of this equipment.

If the parts of the contract goods are found to be defective within the warranty period, but the normal operation of the contract goods will not be affected, the warranty period of the repaired or replaced parts will be recalculated.
4. The end of the quality guarantee period cannot be regarded as the release of our responsibility for potential defects that may cause damage to the contract goods. During the service life of the contract goods, if there are potential defects in the contract goods, the buyer has the right to ask us to repair or replace the defective contract goods and the same batch of contract goods in time at the cost price.

6. During the service life of the contract goods, when we find potential defects or principled errors in the contract goods, we will inform the buyer in writing as soon as possible.
7. For the contract goods, we use mature technology and materials that have been proved to be correct by operating experience; If we adopt new technologies and materials that have not been used in the past, we should get the buyer's consent in advance. The buyer's consent does not relieve or exempt us from our responsibilities under this contract. We should be responsible for all quality problems of equipment and components purchased from subcontractors.
8. If the contract goods provided by us are defective, or the contract goods are scrapped or the project is reworked due to technical data errors or the guidance of our technicians, we shall immediately replace them free of charge or compensate the buyer for the losses incurred. If it is necessary to replace the contract goods, we will bear all the expenses arising from the replacement at the installation site, including but not limited to the cost of new goods, the cost of transporting new goods to the installation site and the cost of handling the replaced goods. The time limit for replacing or repairing the contract goods shall be as agreed by both parties. If the replacement or repair work is not completed within the time limit, it shall be treated as delayed delivery.
9. If the buyer fails to install, operate or maintain the contract goods according to the technical data, drawings and instructions provided by us, or the contract goods are damaged due to reasons other than our technicians, the buyer shall be responsible for repairing and replacing them, but we are obliged to provide the parts that need to be replaced as soon as possible. For the urgent parts required by the buyer, we will arrange to transport them in the fastest way, and all expenses will be borne by the buyer.
10. During the period from the delivery date of the contract goods to the end of the quality guarantee period, if the contract goods provided by us are found to be defective and inconsistent with this contract, the buyer has the right to choose, and we need to take the following remedial measures:
Repair 10 and 1
