79-1
Note
  • 1. In this chapter the following expressions have the meanings hereby assigned to them:
    • (a) Bars and rods
      Rolled, extruded, drawn or forged products, not in coils, which have a uniform solid cross section along their whole length in the shape of circles, ovals, rectangles (including squares), equilateral triangles or regular convex polygons (including "flattened circles" and "modified rectangles", of which two opposite sides are convex arcs, the other two sides being straight, of equal length and parallel). Products with a rectangular (including square), triangular or polygonal cross section may have corners rounded along their whole length. The thickness of such products which have a rectangular (including "modified rectangular") cross section exceeds one-tenth of the width. The expression also covers cast or sintered products, of the same forms and dimensions, which have been subsequently worked after production (otherwise than by simple trimming or descaling), provided that they have not thereby assumed the character of articles or products of other headings.
    • (b) Profiles
      Rolled, extruded, drawn, forged or formed products, coiled or not, of a uniform cross section along their whole length, which do not conform to any of the definitions of bars, rods, wire, plates, sheets, strip, foil, tubes or pipes. The expression also covers cast or sintered products, of the same forms, which have been subsequently worked after production (otherwise than by simple trimming or descaling), provided that they have not thereby assumed the character of articles or products of other headings.
    • (c) Wire
      Rolled, extruded or drawn products, in coils, which have a uniform solid cross section along their whole length in the shape of circles, ovals, rectangles (including squares), equilateral triangles or regular convex polygons (including "flattened circles" and "modified rectangles", of which two opposite sides are convex arcs, the other two sides being straight, of equal length and parallel). Products with a rectangular (including square), triangular or polygonal cross section may have corners rounded along their whole length. The thickness of such products which have a rectangular (including "modified rectangular") cross section exceeds one-tenth of the width.
    • (d) Plates, sheets, strip and foil
      Flat-surfaced products (other than the unwrought products of heading 7901), coiled or not, of solid rectangular (other than square) cross section with or without rounded corners (including "modified rectangles" of which two opposite sides are convex arcs, the other two sides being straight, of equal length and parallel) of a uniform thickness, which are:
      • - of rectangular (including square) shape with a thickness not exceeding one-tenth of the width,
      • - of a shape other than rectangular or square, of any size, provided that they do not assume the character of articles or products of other headings.
      Heading 7905 applies, inter alia, to plates, sheets, strip and foil with patterns (for example, grooves, ribs, checkers, tears, buttons, lozenges) and to such products which have been perforated, corrugated, polished or coated, provided that they do not thereby assume the character of articles or products of other headings.
    • (e) Tubes and pipes
      Hollow products, coiled or not, which have a uniform cross section with only one enclosed void along their whole length in the shape of circles, ovals, rectangles (including squares), equilateral triangles or regular convex polygons, and which have a uniform wall thickness. Products with a rectangular (including square), equilateral triangular or regular convex polygonal cross section, which may have corners rounded along their whole length, are also to be considered as tubes and pipes provided the inner and outer cross sections are concentric and have the same form and orientation. Tubes and pipes of the foregoing cross sections may be polished, coated, bent, threaded, drilled, waisted, expanded, cone-shaped or fitted with flanges, collars or rings.
Subheading Note
  • 1. In this chapter the following expressions have the meanings hereby assigned to them:
    • (a) Zinc, not alloyed
      Metal containing by weight at least 97.5 percent of zinc.
    • (b) Zinc alloys
      Metallic substances in which zinc predominates by weight over each of the other elements, provided that the total content by weight of such other elements exceeds 2.5 percent.
    • (c) Zinc dust
      Dust obtained by condensation of zinc vapor, consisting of spherical particles which are finer than zinc powders. At least 80 percent by weight of the particles pass through a sieve with 63 micrometers (microns) mesh. It must contain at least 85 percent by weight of metallic zinc.
Additional U.S. Note
  • 1. For the purposes of heading 7901, "casting-grade zinc" contains by weight at least 97.5 percent of zinc and contains by weight one or more of the following elements in the quantity indicated:
    • (a) more than 1.8 percent of lead,
    • (b) more than 1.8 percent of cadmium,
    • (c) more than 1.8 percent of iron,
    • (d) more than 0.5 percent of aluminum,
    • (e) more than 1 percent of copper,
    • (f) more than 0.08 percent of titanium,
    • (g) more than 0.1 percent of any other base metal, taken separately.
Compiler's Note
The provisions of subchapter II of chapter 99 (Miscellaneous Tariff Bills or MTBs), the provisions of the Generalized System of Preferences (GSP) found in General Note 4 and most product exclusions from the additional tariffs on products of China in subchapter III of chapter 99 expired on December 31, 2020. However, no endnotes or footnotes relating to these provisions have been deleted as of the issue date of this edition.
