Push, Pull & Early Walk Toys: 3 products from 3 verified suppliers in Chenghai and Yunhe. Push and pull toys are built around a handle, a cord or a wheeled base. Materials are mostly beech or pine, ABS, and sometimes plush over a plastic frame, with non-toxic paint and rounded edges. The mechanism is simple, so the real work is in the axle, the cord length and the wheel fixing. Chenghai covers molded plastic lines and Yunhe covers wooden lines, which is why both appear together in this category. Certification scope should list the toy and any cord or strap, since strangulation clauses apply separately. Ask first about cord length limits, wheel pull-off force, and whether the master carton is sized for retail shelf display.
