Я от импортеров в ЕС еще не могу дождаться ответа, но там, как видится, точно такие же примечания и пояснения:
9503 00 70
Other toys, put up in sets or outfits
‘Sets’ of this subheading consist of two or more different types of articles (principally, for amusement), put up in the same packing for retail sale without repacking.
Articles of the same subheading, except for items covered by subheadings 9503 00 95 or 9503 00 99 (since these subheadings may include miscellaneous articles of different types), are not to be considered different types of articles.
Apart from the articles forming a set, simple accessories or objects of minor importance intended to be used with the articles (for example, a plastic carrot or a plastic brush for a toy animal) can be present.
