HS Code for Ground cork

Ground cork is classified under HS code 4501.90, which falls within Chapter 45 of the Harmonized System, covering cork and articles of cork. This specific subheading is designated for waste cork as well as crushed, granulated, or ground cork. The classification is determined by General Interpretative Rule (GRI) 1, which dictates that classification is governed by the terms of the headings and any relative section or chapter notes. Heading 4501 specifically includes natural cork in its raw state or simply prepared, but 4501.90 is the residual category for cork that has been mechanically reduced in size. To remain under this code, the ground cork must consist of pure cork particles without the addition of any binding substances or adhesives. If the ground cork were to be compressed and held together by a binder, it would undergo a character change and move to a different heading entirely. The material typically originates from the bark of the cork oak tree (Quercus suber) and is often a byproduct of the manufacturing process for natural cork stoppers.

Common Misclassification

Ground cork is frequently misclassified under HS code 4504.10, which covers agglomerated cork. The primary distinction is the presence of a binding substance. If the ground cork has been mixed with glue, resin, or other adhesives to form blocks, sheets, or strips, it must be classified under 4504. Another common error is using 4502.00, which is reserved for natural cork that has been de-backed or roughly squared, rather than reduced to granules or powder.
