Get immediate, transparent bulk and breakbulk freight indications. RatePort is a 24/7 freight-estimation and benchmarking tool for bulk and breakbulk voyage planning. It helps users save time by producing consistent, explainable freight indications whenever they need them, regardless of location or time zone. Enter cargo and voyage details, see how estimated costs are calculated, compare voyage alternatives and decide whether to request a firm commercial offer. RatePort is designed to be a trusted, transparent source for internal freight benchmarking, budgeting, planning and early commercial discussions. Its explainable approach helps users understand the assumptions and cost components behind an estimate rather than rely on an unexplained result. Key features: • Create on-demand freight indications 24/7 across global time zones • Generate consistent bulk and breakbulk voyage estimates • Review a transparent breakdown of estimated costs • Compare alternative voyage scenarios • Save and manage previous indications • Create and share professional PDF indication summaries • Share indication details through WhatsApp • Request a firm commercial offer Designed for: • Commodity traders • Charterers • Shipowners and operators • Shipbrokers • Freight forwarders • Importers and exporters • Manufacturers and industrial producers • Mills, mines and mineral producers • Government agencies and public bodies • Universities, maritime academies and research institutions RatePort offers complimentary introductory use. Additional usage and subscription plans are available as in-app purchases. Important: RatePort results are non-binding freight indications provided for benchmarking, budgeting, planning and comparison. They do not constitute firm or bookable commercial offers. Users may request a separate firm commercial offer through the app. Breakbulk results are voyage-based estimates derived from cargo and voyage details. RatePort does not provide or compare third-party carrier tariff schedules. Actual freight may vary based on vessel availability, market conditions, cargo particulars, ports, dates and other commercial factors.
