Customs Declarations UK vs Customs OS

Customs Declarations UK is a cloud platform for filing Great Britain import and export declarations directly with HMRC’s Customs Declaration Service. It supports GB CDS imports and exports, GB ENS, EU ICS2 entry summary declarations, and NCTS6 T1/T2 transit movements. Guided filing wizards adapt to shipment requirements, while real-time validation flags inconsistencies before submission. Its document-processing system uses OCR and AI to read invoices, packing lists, and transport documents, then drafts supported declarations for human review. API connections can link it with TMS, ERP, and freight software for document intake and drafting. The platform also integrates with CSPs MCP, CNS, and CCS-UK and includes GVMS management. The company offers onboarding, training, and assistance with complex customs scenarios. Pay-as-you-go has no monthly fee, although onboarding charges may apply; subscriptions require at least six months’ notice to cancel. Filing prices vary: EU ICS2 is £4 per declaration, GB CDS is £25, and NCTS6 departures are £15. NCTS6 filings require the customer’s own transit guarantee.

Customs OS is a web service for licensed customs brokers and their operations teams. It reads customs document packets, extracts fields and cross-checks information using a deterministic rule engine; document validation is described as being in private beta. Users can upload or drag in scanned or digital commercial invoices, packing lists, bills of lading, certificates of origin and arrival notices. Checks span declared value, country of origin, incoterms, shipper, consignee, weights and dates. Extracted values trace back to the source document and page, while pass or fail results link to named, versioned rules. Brokers can confirm or dismiss flagged exceptions, with decisions recorded against the packet. Customs OS does not file automatically: a licensed broker reviews outputs before acting. Packet content is sent to Google's Gemini models through the Vercel AI Gateway for extraction and validation, and the privacy policy says it is not used to train models. Listed safeguards include TLS 1.2+ in transit, AES-256 at rest, tenant isolation and least-privilege internal access. Pricing is on request. HTS classification, ISF watcher and CBP Form 7501 drafting are roadmap items, not current service features.
