Generally yes — buckets, grabs, and grips are classified by their own character as attachments regardless of whether they accompany new equipment or are imported separately as replacements. However, when imported as a set with a complete machine, the classification of the whole unit may govern; consult a customs broker to confirm the correct treatment for bundled shipments.

Buckets are open-fronted scooping tools that rely on the machine's crowd motion to fill, while grabs (clamshell or orange-peel types) use opposing jaws that close to capture material. Both fall under this heading, but the distinction can matter for end-use documentation and for matching the correct spare-parts specification when sourcing replacements.
