Tools
Interactive calculators and planners built on the same documented rule data as the rest of the site. Nothing is invented — tools read the published rules and help you apply them to your trip or shipment.
Duty calculator
Estimate landed cost (customs value + duty + VAT) for any HS chapter across documented lanes. Preferential/FTA rate toggle applies when the lane's documented notes mention a trade agreement.
Trip planner
Pick an origin + destination and a set of items you plan to carry. Returns a single report grouped by prohibited / restricted / allowed, with links to each rule. Saves to your browser.
Customs declaration prep sheet
Printable one-page checklist: what to declare, documentation to carry, and cash-declaration flag for your destination. Not a customs form — a prep sheet.
HS code finder
Plain-English search across all HS chapters and documented items. Cross-links to the canonical chapter + item pages for confirmation.
Compare rules
Side-by-side: one item across many countries, or one country across many items. Client-side pivot. Only documented rules appear — blanks mean 'not documented', not 'allowed'.
Penalty comparator
Matrix view of rule status (allowed / restricted / prohibited) across all documented items × countries. Click any cell to open the full rule.

Landed-cost calculator
Origin + destination + HS chapter + value → estimated customs duty + VAT/GST + total landed cost. Uses the 3,500-entry bilateral duty matrix and destination de-minimis thresholds.
Multi-stop itinerary planner
Add 5+ destinations and items you're carrying — get a per-stop carriage-rule matrix in one view. Useful for round-the-world or multi-country trips.

Compare carriers
Side-by-side comparison of carriers across prohibited items, weight + dimension limits, and destination-specific restrictions.
Border risk checker
Pick a destination + purpose + items. Get a per-item allowed / restricted / prohibited verdict, the documents you may need, and links to the underlying rule pages.
Packing list validator
Paste a packing list (one item per line). Grouped output: AVOID, DECLARE, CHECK ALLOWANCE, VERIFY. Catches the high-risk items before you fly.
Parcel customs form helper
CN22 / CN23 pre-flight check: vague descriptions, undervaluation, missing HS codes, gift-relief misuse patterns. Output a clean field set ready to paste into your postal operator.
Commercial invoice builder
Browser-only commercial invoice template: exporter / importer, line items with HS codes + origin, Incoterm, freight + insurance. Print or copy as text.
Incoterm selector
Answer 6 questions about who arranges transport / insurance / clearance. The selector recommends the closest Incoterm 2020 plus alternatives, with links to each Incoterm detail page.
Document checklist generator
Destination + purpose + category → the documents typically required (commercial invoice, phytosanitary, prescription, FCC, end-use cert, etc.) with notes on when each applies.
