Platform

One operations layer.
Every cross-border step.

Four integrated modules — HS Classifier, Tariff Calculator, Document Generator, Trade Intelligence — backed by a REST API and a tamper-evident audit ledger. Every AI action runs through Band A→D approval gates.

Module 01

HS Classifier

Derives 6–10 digit Harmonized System codes from product category, ingredient list, destination market, and declared value. Returns a confidence-scored classification with regulatory status, required documents, and any prohibited-ingredient flags.

  • Chapter-level to 10-digit precision depending on corridor requirements
  • Source-grounded output: confirmed vs. AI-assumption vs. missing data clearly labelled
  • CN customs category labels (中文) auto-appended for CN-bound goods
  • Batch classify up to 50 SKUs per API call
  • Confidence range 0.60–0.98; low-confidence items flagged for broker review
  • Integrates with CN GACC positive list and CBEC permitted categories

Module 02

Tariff Calculator

Calculates landed cost for a shipment: MFN duty, preferential rate (CEPA/RCEP), VAT, additional taxes, and CBEC-specific rules including de minimis thresholds. Outputs a line-by-line cost breakdown that a CFO can audit.

  • CEPA preferential rate: 0% for qualifying HK-origin goods to CN
  • RCEP preferential rates for CN ↔ ASEAN-8 member corridors
  • CBEC cross-border e-commerce tax rules (行邮税 vs standard import tax)
  • De minimis thresholds by corridor (CNY 50 / CNY 1,000 CBEC threshold)
  • VAT and additional taxes (consumption tax where applicable)
  • Landed cost summary exportable as PDF or JSON

Module 03

Document Generator

Generates customs-ready trade documents from your shipment data. Commercial invoice, packing list, certificate of origin (for CEPA/RCEP claims), and customs declaration drafts. Band D gated — no declaration is filed without a logged human signature.

  • Packing list with net/gross weight and carton-count breakdown
  • Certificate of Origin draft (Form CO / Form E / Form N) for broker completion
  • CN customs declaration (报关单) pre-fill from HS classification data
  • CBEC platform filing data packet (天猫国际/京东国际/抖音跨境 formats)
  • All filing actions Band D gated — AI drafts, human signs, system records
Band A
Read-only: classification queries, tariff lookups
Band B
Draft generation: documents, estimates
Band C
Prepare: pre-fill declaration data
Band D — Blocked
File, pay, submit: requires human signature + logged approval
