HS Code 28.03 – Carbon; carbon blacks and other forms of carbon n.e.c.

HS code 2803 is a 4-digit heading in the Harmonized System that covers: Carbon; carbon blacks and other forms of carbon n.e.c.. HS Code 2803 encompasses various forms of elemental carbon, specifically carbon blacks and other forms of carbon not elsewhere specified (n.e.c.). This heading is critical for delineating specific carbon types from other elemental carbon forms like natural graphite (2504), diamonds (7102), or activated carbon specifically prepared for gas/liquid purification (3802). The scope includes industrial carbons produced through thermal decomposition or incomplete combustion of hydrocarbons, such as lamp black, acetylene black, and particularly carbon black, which is a major sub-category. Carbon black is primarily used as a reinforcing filler in rubber products, especially tires, and as a pigment in plastics, paints, and inks. Other forms of carbon n.e.c. might include retort carbon. This classification is vital for trade compliance due to the diverse applications and industrial significance of these carbons. Accurate classification ensures correct tariff application, adherence to specific environmental regulations concerning carbon emissions or hazardous material handling (e.g., certain carbon blacks are fine powders), and compliance with product-specific standards. Historically, carbon black production has evolved with the automotive industry, making it a key commodity in global trade. This heading complements other carbon classifications within the HS, providing a specific home for industrially produced elemental carbons that don't fit into the more specialized categories of Chapter 25 (mineral products) or Chapter 71 (precious stones).

Carbon black, furnace black, channel black, thermal black, acetylene black, lamp black, retort carbon, carbon for electrodes (n.e.c.), pigment carbon black, conductive carbon black, rubber grade carbon black, plastics grade carbon black, fiber grade carbon black, special blacks, carbon for dry cells (n.e.c.), carbon for brushes (n.e.c.), amorphous carbon (n.e.c.), carbon nanotubes (n.e.c. if not composite), carbon nanofibers (n.e.c. if not composite), carbon for printing inks, carbon for coatings, carbon for toners, carbon for sealants, carbon for adhesives, carbon for insulation

Common misclassifications under 2803 include confusing it with natural graphite (2504), activated carbon (3802), or even carbon fibers (6815). Natural graphite is specifically classified under 2504. Activated carbon, which is carbon treated to increase its porosity for adsorption, falls under 3802. Carbon fibers, often used in composites, are generally classified under 6815 or as textile materials, not under 2803. The key distinction for 2803 is that it covers elemental carbons produced industrially, primarily carbon blacks, and other forms of carbon that are not specifically provided for elsewhere, emphasizing their uncombined, non-activated, and non-fibrous nature.

In 2025, the top exporters of HS code 2803 in UN Comtrade data were China ($1.2B, 20% of world exports), India ($518M) and Russia (about $438M). World exports came to about $6.3B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 2803 in UN Comtrade data were China ($603M, 9.5% of world imports), Thailand ($509M) and the United States ($421M). World imports came to about $6.3B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 2803 is a 4-digit heading under Chapter 28 of the Harmonized System. The first 2 digits (28) identify the chapter, and digits 3-4 (03) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
