Graphics such as national flag and national emblem are not within the protection scope of the Trademark Law, but are under the jurisdiction of the National Flag Law. Generally, the national flag laws of various countries only limit the scope of use of national signs to whether the use of the signs is serious (for example, the national emblem of China cannot appear on underwear) and whether the appearance of the signs is complete and clear.

in business situations, the national symbol cannot be used as the main part of business activities, but it can be used as an auxiliary element.

In some cases, the national football team may be related to commercial operation. In this case, the football team emblem may be registered as a trademark and used in some commercial occasions.

as long as the team logo is registered as a trademark, it will be protected by the trademark law, but it can be used for non-profit purposes in ordinary non-commercial occasions. To sum up: there is nothing wrong with printing the national emblem on football, while printing the team emblem requires examining the copyright status of each symbol. Of course, in practice, a small enterprise produces tens of thousands of football, which is nobody's business.
