Rebar - reinforcement steel bars Hs Code

Rebar - reinforcement steel bars harmonized system code

Product Overview Rebar, or Reinforcement Steel Bars classified under HS Code 721420, refers to carbon steel bars specifically manufactured for reinforcing concrete structures in construction and infrastructure projects. These bars are typically produced through hot-rolling processes, resulting in ribbed or deformed surfaces that enhance mechanical bonding with concrete. The product range under this classification includes various grades differentiated by tensile strength, diameter (commonly ranging from 6 mm to 40 mm), and surface treatment levels, such as epoxy coating or galvanization for corrosion resistance. Subcategories within HS Code 721420 encompass plain bars, deformed bars, and those with specific mechanical properties tailored to meet national and international standards like ASTM A615, BS 4449, or ISO 6935. Commercially, rebar is integral to civil engineering, residential and commercial construction, and infrastructure development, providing essential structural reinforcement. Its value proposition lies in its high tensile strength-to-weight ratio, dimensional accuracy, and compliance with stringent quality controls, making it a preferred choice for importers and contractors seeking durable and standardized reinforcement solutions. HS Code Classification & Trade Specifications The Harmonized System (HS) Code 721420 falls under Chapter 72 (Iron and Steel), Heading 7214 (Flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, clad, plated or coated), with the subheading 721420 specifically designated for “Other bars and rods of iron or non-alloy steel, not further worked than hot-rolled, hot-drawn or hot-extruded, but including those twisted after rolling.” This classification is justified by the product’s manufacturing process and its physical state, distinguishing it from cold-formed or alloyed steel bars. Typical trade packaging involves bundling bars in standardized lengths (commonly 6 to 12 meters) secured with steel straps and protected with anti-corrosive wrapping or coatings to prevent oxidation during transit. Shipping methods prioritize bulk cargo handling with attention to weight distribution and moisture control to maintain product integrity. Quality standards adhere to international norms such as ISO 6935-2 and meet WTO-compliant customs documentation requirements, ensuring uniform classification and facilitating smooth customs clearance. The accurate application of HS Code 721420 supports compliance in import/export operations, tariff assessments, and trade data reporting.

(c) Ferro-alloys Alloys in pigs, blocks, lumps or similar primary forms, in forms obtained by continuous casting and also in granular or powder forms, whether or not agglomerated, commonly used as an additive in the manufacture of other alloys or as de-oxidants, de-sulphurising agents or for similar uses in ferrous metallurgy and generally not usefully malleable, containing by weight 4 % or more of the element iron and one or more of the following : - more than 10 % of chromium - more than 30 % of manganese - more than 3 % of phosphorus - more than 8 % of silicon - a total of more than 10 % of other elements, excluding carbon, subject to a maximum content of 10 % in the case of copper.(d) Steel Ferrous materials other than those of heading 72.03 which (with the exception of certain types produced in the form of castings) are usefully malleable and which contain by weight 2 % or less of carbon. However, chromium steels may contain higher proportions of carbon. (e) Stainless steel Alloy steels containing, by weight, 1.2 % or less of carbon and 10.5 % or more of chromium, with or without other elements. (f) Other alloy steel Steels not complying with the definition of stainless steel and containing by weight one or more of the following elements in the proportion shown : - 0.3 % or more of aluminium - 0.0008 % or more of boron - 0.3 % or more of chromium - 0.3 % or more of cobalt - 0.4 % or more of copper - 0.4 % or more of lead - 1.65 % or more of manganese - 0.08 % or more of molybdenum - 0.3 % or more of nickel - 0.06 % or more of niobium - 0.6 % or more of silicon - 0.05 % or more of titanium - 0.3 % or more of tungsten (wolfram) - 0.1 % or more of vanadium - 0.05 % or more of zirconium - 0.1 % or more of other elements (except sulphur, phosphorus, carbon and nitrogen), taken separately. (g) Remelting scrap ingots of iron or steel Products roughly cast in the form of ingots without feeder-heads or hot tops, or of pigs, having obvious surface faults and not complying with the chemical composition of pig iron, spiegeleisen or ferro-alloys. (h) Granules Products of which less than 90 % by weight passes through a sieve with a mesh aperture of 1 mm and of which 90 % or more by weight passes through a sieve with a mesh aperture of 5 mm. (ij) Semi-finished products Continuous cast products of solid section, whether or not subjected to primary hot-rolling; and Other products of solid section, which have not been further worked than subjected to primary hotrolling or roughly shaped by forging, including blanks for angles, shapes or sections. These products are not presented in coils. (k) Flat-rolled products Rolled products of solid rectangular (other than square) cross-section, which do not conform to the definition at (ij) above in the form of : - coils of successively superimposed layers, or - straight lengths, which if of a thickness less than 4.75 mm are of a width measuring at least ten times the thickness or if of a thickness of 4.75 mm or more are of a width which exceeds 150 mm and measures at least twice the thickness. Flat-rolled products include those with patterns in relief derived directly from rolling (for example, grooves, ribs, chequers, tears, buttons, lozenges) and those which have been perforated, corrugated or polished, provided that they do not thereby assume the character of articles or products of other headings.Flat-rolled products of a shape other than rectangular or square, of any size, are to be classified as products of a width of 600 mm or more, provided that they do not assume the character of articles or products of other headings. (l) Bars and rods, hot-rolled, in irregularly wound coils Hot-rolled products in irregularly wound coils, which have a solid cross-section in the shape of circles, segments of circles, ovals, rectangles (including squares), triangles or other 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). These products may have indentations, ribs, grooves or other deformations produced during the rolling process (reinforcing bars and rods). (m) Other bars and rods Products which do not conform to any of the definitions at (ij), (k) or (l) above or to the definition of wire, which have a uniform solid cross-section along their whole length in the shape of circles, segments of circles, ovals, rectangles (including squares), triangles or other 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). These products may : - have indentations, ribs, grooves or other deformations produced during the rolling process (reinforcing bars and rods); - be twisted after rolling. (n) Angles, shapes and sections Products having a uniform solid cross-section along their whole length which do not conform to any of the definitions at (ij), (k), (l) or (m) above or to the definition of wire.
