The quality clause of the commodity is the basic clause of the export contract. The Seller shall foot the goods according to the quality terms stipulated in the contract, otherwise the buyer shall have the right to lodge a claim or refuse to accept the goods, or even to cancel the contract. Therefore, we should pay attention to the following questions when making quality clauses:

1. determine the way to express quality according to the characteristics of commodities. The way to express the quality should be determined according to the characteristics of the goods. If we can express it in one way, we should not adopt two or more than two methods. It is too cumbersome to make the production and delivery difficult.

2. the conclusion of quality clause should be scientific and reasonable. When the quality clause is stipulated, the wording should be simple, specific and definite. Avoid using vague words such as "approximate", "left and right", "reasonable error", and avoid disputes. In addition, it is necessary to prevent the quality clause from being too high or too low in terms of production practice, resulting in difficulties in production or delivery or affecting sales.

3. quality clauses should conform to the standards of relevant countries or relevant international organizations, so as to enhance the competitiveness of products.
