This isan official Google announcementregarding structured data in website SEO. Google will officially stop supporting data-vocabulary.org structured data starting April 6th. This means if your website's structured data format still uses data-vocabulary.org, you should promptly replace it with schema.org.

For current domestic foreign trade websites, disabling this should have minimal impact on you, as the vast majority of foreign trade websites do not have structured data code at all, so it won't bring any effect.
