Hong Kong’s premier marine fuel supplier, Chimbusco Pan Nation (CPN), has successfully executed its first-ever B100 marine biodiesel delivery to an oil tanker, bunkering the vessel TORM CORRIDO using its specialized, Type II chemical-certified bunker barge, Guo Si. This milestone marks a significant cross-segment expansion into the liquid bulk sector during a period of explosive market growth, with CPN’s total B100 volumes for the second quarter of 2026 skyrocketing by over 300% quarter-on-quarter. By overcoming the stringent regulatory and technical hurdles associated with pure biofuels, CPN has solidified Hong Kong’s position as a compliant alternative refueling hub capable of delivering immediate, zero-carbon-intensity solutions to the global merchant fleet.
Hong Kong | June 10, 2026 – In a landmark development for Asia’s alternative marine fuel landscape, Chimbusco Pan Nation (CPN) has successfully executed its first-ever 100% marine biodiesel (B100) bunkering operation for an oil tanker.
The breakthrough delivery, which took place in Hong Kong waters on June 8, 2026, involved the fueling of the product tanker TORM CORRIDO. The operation officially extends CPN’s B100 supply capabilities into the liquid bulk sector, marking a critical milestone for Hong Kong’s transition into a premier hub for certified, zero-carbon-intensity maritime fuels.
Exponential Growth: Market Demand Triples
The successful stemming of TORM CORRIDO occurs against the backdrop of an aggressive demand curve for pure biofuels in the region. Since CPN commercially launched its B100 marine biodiesel service in January 2026, local market adoption has scaled at a blistering pace.
Driven by tightening regulatory frameworks, including the European Union’s Emissions Trading System (EU ETS) impacting voyages to and from Europe, and the looming FuelEU Maritime mandates, ship operators are rapidly shifting from low-percentage biodiesel blends (such as B24) to pure B100 to maximize their carbon accounting credits.
CPN confirmed that total B100 volumes delivered in the second quarter of 2026 have skyrocketed by over 300% compared to Q1 2026 results, underscoring a massive, quarter-on-quarter tripling of physical demand.
Regulatory and Technical Execution: The Guo Si Advantage
Bunkering pure B100 presents unique technical and regulatory hurdles. Under international maritime law, fuels containing more than 25% biodiesel are classified as chemicals and must be transported via vessels that comply strictly with chemical tanker safety codes.
The operation was executed by CPN’s specialized bunker tanker, Guo Si. The vessel stands out as a critical asset in Hong Kong’s harbor infrastructure:
- Type II Chemical Certification: The Guo Si has been fully upgraded to meet the rigid stipulations of the International Maritime Organization’s (IMO) IBC Code (International Bulk Chemical Code).
- Local Compliance: The barge is fully certified under Hong Kong Cap. 413E (Merchant Shipping Safety/Control of Pollution by Noxious Liquid Substances in Bulk Regulations).
- Monopoly on Pure Bio: As Hong Kong’s only Type II-certified bunker tanker rated for B100 operations, the Guo Si gives CPN exclusive, fully compliant physical delivery capability for pure biofuels across all major merchant ship types in the region.
Strategic Synergies and Decarbonization Targets
The inclusion of TORM, one of the world’s largest product tanker owners and operators, as a primary partner underscores the cross-segment appeal of high-concentration biofuels. Tanker operators face unique decarbonization pressures; by utilizing drop-in B100, they can achieve immediate, dramatic reductions in Well-to-Wake greenhouse gas emissions without necessitating costly engine modifications or retrofits.
For CPN, this milestone caps 34 years of evolution. Founded in 1991 as a local single-barge operator in Hong Kong, CPN has systematically scaled into a dominant physical bunker supplier and international bunker trader operating across nine global offices.
Looking Forward
As the maritime sector faces increasingly steep penalties for carbon intensity, the ability to lift certified B100 at scale in major Asian ports like Hong Kong will become a key differentiator for global shipping lines. CPN’s ability to safely bridge the technical gap using the Guo Si sets a new baseline for alternative fuel infrastructure in the Far East, transforming pure marine biodiesel from an experimental trial fuel into a reliable, everyday bunkering reality.
