(a) Other acceptable methods. Except for articles described in Sec. 134.43 of this part or the subject of a ruling by the Commissioner of Customs, any method of marking at any location insuring that country of origin will conspicuously appear on the article shall be acceptable. Such marking must be legible and sufficiently permanent so that it will remain on the article (or its container when the container and not the article is required to be marked) until it reaches the ultimate purchaser unless deliberately removed.
(b) Articles marked with paper sticker labels. If paper sticker or pressure sensitive labels are used, they must be affixed in a conspicuous place and so securely that unless deliberately removed they will remain on the article while it is in storage or on display and until it is delivered to the ultimate purchaser.
(c) Articles marked with tags. When tags are used, they must be attached in a conspicuous place and in a manner which assures that unless deliberately removed they will remain on the article until it reaches the ultimate purchaser.
