About the Company

Ocean Sciences Ltd trades on the Australian Securities Exchange under the code OSS and describes itself as a leading commercial seaweed supply, research and development company. Its Indonesian operating Subsidiary is PT BPH Global Indonesia, which handles the seaweed trading activity referred to in its latest announcement.

Francesco Cannavo is Chairman and Matthew Leonard is Managing Director. The company's announcements are authorised for release by its Board, and media and Investor relations are handled by Peter Taylor of NWR Communications.

Business Overview

Ocean Sciences' trading activities to date have focused on Kappaphycus alvarezii, known as Cottonii, which is primarily used in the production of kappa-carrageenan. The company sources Indonesian seaweed through an established procurement network and supports it with quality control processes and export infrastructure.

The company has now added a second species, Eucheuma spinosum, known as Spinosum. It states that Cottonii and Spinosum are the two principal commercially cultivated carrageenan-producing seaweed species, together accounting for approximately 90% of the seaweed used in global carrageenan production.

First Commercial Spinosum Sale

In its announcement dated 21 October 2026, Ocean Sciences reported that PT BPH Global Indonesia had secured its first commercial sale of Spinosum. The company received a purchase order from an existing Chinese customer, Greenwich (China) Technology Development Limited, for 25 metric tonnes of Indonesian Spinosum seaweed.

The shipment has arrived at Xiamen Port in China. It will now be subject to the applicable customs inspection and clearance procedures before delivery to the customer. The company described the sale as a milestone in the expansion of its seaweed trading operations beyond Cottonii and as an expansion of its commercial product offering, addressable customer base and growth options.

Carrageenan Market Segments

The announcement distinguishes between two segments of the carrageenan market. Cottonii supplies the kappa-carrageenan market, while Spinosum is the principal raw material used to produce iota-carrageenan, a distinct form of carrageenan used in dairy desserts, plant-based food products, personal care products and pharmaceuticals.

Managing Director Matthew Leonard said the sale allows the company to participate in a separate segment of the global carrageenan market. He said the company believes broader products will help it expand its customer base and increase trading volumes. The company stated that it will continue to pursue expanded trading across both Cottonii and Spinosum as part of a diversified and scalable international seaweed business.

Related Sector Context

Seaweed-derived carrageenan is used as an ingredient across food, personal care and pharmaceutical applications, and the Supply chain links seaweed farming regions with processors in importing countries. Trading companies in this area depend on procurement, quality control, shipping and customs processes, and the company's own announcement identifies customs clearance as the step between arrival of a shipment and delivery to the buyer. On the day of the data, the S&P/ASX 200 was down 0.64% and the All Ordinaries down 0.66% at 11:55 am, while Ocean Sciences shares were up 6.67% at $0.016.

Risks to Weigh In

Delivery of the Spinosum shipment remains subject to customs inspection and clearance in China, so the sale has not yet been completed. The announcement describes a single purchase order of 25 metric tonnes, and it does not disclose the contract value, pricing or margin.

The company is also extending a trading Business built around one species into a second, which involves developing a separate customer base within the iota-carrageenan segment, which the company describes as distinct from the kappa-carrageenan market it has supplied so far. Repeat orders, trading volumes and any further Spinosum sales are described as intentions rather than contracted outcomes, and the announcement provides no financial forecast.

Catalysts on Watch

The announcement points to the completion of customs inspection and clearance at Xiamen Port and delivery to the customer as the next steps for the first shipment. Beyond that, the company says it will continue to pursue expanded trading activities across Cottonii and Spinosum, including growth in its customer base and trading volumes. No dates were provided for further orders or for the completion of clearance, and the company did not state how many further Spinosum orders are in progress or expected.

Putting It Together

Ocean Sciences shares were up 6.67% at $0.016 during the 22 October 2026 session while the S&P/ASX 200 and All Ordinaries were lower. The company's latest report describes a first Spinosum sale that has reached China and is awaiting customs clearance, with financial terms not disclosed.
