Which of the following conditions must be met for some articles to be marked appropriately?

For articles to be marked appropriately, they must meet specific marking requirements outlined by customs regulations. These requirements vary depending on the type of item and the country of origin. Proper marking ensures that consumers are aware of the origins of the products they purchase, which can affect their buying decisions and comply with legal obligations.

Marking requirements typically include information such as the country of origin, and in some cases, additional details about the manufacturer or distributor. This clarity helps to prevent misrepresentation and can also play a significant role in duties and tariffs assessed on goods, ensuring that proper customs procedures are followed.

The other options, while related to customs procedures, do not pertain directly to the conditions needed for appropriate marking. For instance, simply being listed in a tariff code or being subject to inspection does not inherently relate to how an item is marked. Export timelines are also not a determining factor for marking compliance. Thus, the focus on specific marking requirements is essential for accurate customs documentation and consumer information.
