Chile absorbs 55% of Brazil's carbon black exports, jumping to top buyer

Carbon black: the input that goes into everything heavy

SH4 2803 covers carbon black — the fine particulate produced from the incomplete combustion of heavy petroleum products — alongside other carbon forms not elsewhere classified. Carbon black is not exotic chemistry. It is an industrial workhorse. Tires are the dominant end use, where carbon black can represent up to 30% of total tire weight for heavy-duty vehicles. Beyond tires, it enters technical rubber compounds, industrial pigments, printing inks, and reinforced plastics. Whoever is buying it in volume is feeding a downstream manufacturing chain with continuous, predictable demand.

Chile's mining sector as the demand engine

Chile operates one of the world's largest mining industries. Copper, lithium, and iron ore extraction rely on massive fleets of heavy-duty vehicles — off-road dump trucks, front-end loaders, drilling rigs — that consume industrial tires at a steady and significant rate. Each of those tires is a substantial carbon black consumer. Brazil, as an integrated producer with geographic proximity and competitive logistics, displaced Asian suppliers for Chilean importers during 2025. A weaker Brazilian real reinforced that competitiveness throughout the year.

The jump from US$ 244,647 to US$ 7.9 million

This was not a new channel being created from zero. In 2024, Chile already ranked 9th, with nearly US$ 245,000 in FOB — a small but functioning commercial relationship. What changed in 2025 was scale. Expanding an existing channel is different from building one from scratch: there is established trust, known import procedures, and commercial relationships that already worked. FOB growing 31× in one year indicates that contracts were expanded, shipment frequency increased, and Chile elevated Brazil to priority supplier status in this category.

What 55.1% concentration actually means

For Brazilian exporters, having 55.1% of a product's sales concentrated in one partner is simultaneously strong and fragile. Strong because the channel is validated, volumes are real, and revenue is predictable. Fragile because any slowdown in Chilean industrial activity — particularly in mining, which is highly sensitive to global commodity price cycles — flows directly into this trade volume. The concentration also gives the Chilean buyer considerable negotiating power on price and payment terms.

South America: the market that remains to be built

With 55.1% going to Chile, the remaining 44.9% distributes across other destinations. Brazil holds a supply leadership position in South America for carbon black, with installed capacity that can serve multiple markets simultaneously. Peru, Colombia, and Argentina are natural next targets — they share supply chain characteristics with Chile and have industrial sectors that consume carbon black. Diversifying from a healthy primary channel is the most comfortable position from which to pursue those adjacent markets.
