Port37 is an AI Customs Broker tool built for cross-border trade. It focuses on HS Code customs classification, tariff rate lookup, FTA preferential rates, landed cost calculation, and compliance checks. Its key approach is βAI + deterministic validationβ: Claude analyzes product descriptions and reasons through classification based on GRI rules, but the final code must exist in a real tariff database, helping prevent the AI from generating non-existent tariff codes.
The product uses a 7-step workflow: product information extraction, hybrid vector and keyword search, knowledge graph traversal, LLM-based classification, hard validation, tariff calculation, and compliance checks. Tariff data sources include USITC, UK Trade Tariff/HMRC, and EU TARIC, with results marked as either officially verified or estimated. Feature-wise, it supports classification across multiple countries in one run, FTA preferential rates, landed cost calculation, compliance certification prompts, and bulk CSV uploads.
Pricing is fairly transparent: the free plan includes 10 classifications per month with no credit card required; Starter is $49/month for 500 classifications; Growth is $199/month for 5,000 classifications; Enterprise is custom-priced with unlimited usage. All plans include 10 countries, FTA rates, and compliance checks. On the developer side, Port37 offers a REST API, SSE streaming API, webhooks, API key management, and rate limits, making it suitable for integration into internal customs declaration, logistics, or e-commerce systems.
The strengths are its low-friction free tier, clear pricing structure, fairly complete API capabilities, and hard validation against real tariff databases, which makes the approach more reliable than a simple LLM Q&A workflow. The drawbacks are its limited country coverage and the fact that data for some countries is estimated. Enterprise procurement details such as team permissions, audit logs, security certifications, privacy compliance, and payment methods have not been disclosed. Annual billing discounts also do not appear to be officially available yet.
Port37 is suitable for cross-border e-commerce sellers, small importers, customs brokers, logistics companies, and system integrators that need to embed classification capabilities via API. The source material does not provide information on access from China, so this remains unknown; payment methods are also not disclosed. If usage in China is affected by network, payment, or data compliance constraints, alternatives include traditional customs brokerage services or directly consulting official databases such as USITC, HMRC, and EU TARIC, though automation and bulk-processing efficiency will be weaker.
