The International Trade Toolkit popup — 7 tools, one interface.
International Trade Toolkit — Essential Tools for Importers & Exporters
Denied-Party Screening · LC Checks · Incoterms · Landed Cost · ISF Deadlines · Certificates · Registration Lookup
Version 1.0 · Updated 2026
International Trade Toolkit is a Chrome extension that brings together seven essential tools for importers, exporters, and trade compliance teams. From denied-party screening to LC discrepancy checking, Incoterms explanations, landed-cost comparison, ISF deadline tracking, and more — everything you need to manage international shipments efficiently.
What Is the International Trade Toolkit?
The International Trade Toolkit is a Chrome extension that brings together 7 essential trade tools into one unified interface. Every tool works with manual entry — no automatic data scraping — and stores all data locally in your browser.
This is the toolkit for import/export businesses who need to screen partners, check LC documents, understand Incoterms, compare landed costs, track ISF deadlines, verify certificates, and log supplier registration checks — all without switching between multiple apps.
Who Should Use This Toolkit?
- Importers & exporters — managing shipments, LC documents, and compliance.
- Trade compliance teams — screening denied parties and tracking ISF filings.
- Freight forwarders — comparing landed costs and explaining Incoterms to clients.
- Sourcing professionals — verifying supplier registrations and business legitimacy.
- Anyone who ships internationally — and needs to stay organized across documents, deadlines, and compliance.
Why You Can Trust the International Trade Toolkit
🔒 Trust built in Transparent logic, local data, and a proven track record.
Every calculation in this toolkit is documented and verifiable. All data stays local in your browser — no external servers, no data collection. The only network calls are optional Gumroad license verification and (if you choose) API calls to market-data providers using your own key.
Two tools do NOT embed data — the Denied-Party Screener and Registration Lookup Helper link directly to official free resources (Trade.gov, OFAC, UK Companies House, US SEC EDGAR, Hong Kong Companies Registry) and log your audit trail. Embedded sanctions lists would be stale and dangerous — this design keeps you compliant and safe.
Battle-tested logic
LC Checker, Landed-Cost Normalizer, and ISF Tracker were tested against multiple real-world scenarios before integration.
Documented calculations
Every formula is transparent and verifiable — no black-box algorithms.
100% local storage
All your data (screening logs, LC checks, supplier comparisons, ISF shipments) stays in your browser.
No hidden data collection
Minimal permissions — only storage, alarms, and notifications.
Why Use This Toolkit? (Key Benefits)
All 7 Tools — Detailed Guides
Each tool below includes its audience, formula (where applicable), key benefit, and a worked example.
1. Lightweight Denied-Party Name Screener
Why use it? Check a name against official free screening tools (Trade.gov Consolidated Screening List, OFAC Sanctions Search), then log what you found for your audit trail.
Key benefit: A structured audit trail of your denied-party checks — essential for compliance recordkeeping.
architecture Safe by design: This tool does NOT embed sanctions-list data. Stale sanctions data would be dangerous — the tool links to official government resources and logs your findings.
Supplier: "ABC Trading Co."
Result: Clear (no matches found in official screening)
→ Logged with timestamp for your compliance records.
Supplier: "XYZ Ltd."
Result: Flagged (potential match found)
→ Logged as "Flagged" — escalate for further review.
2. Letter of Credit Discrepancy Pre-Checker
Why use it? Check your shipping documents against LC terms before presenting to the bank — catch discrepancies early.
Key benefit: Avoid costly LC rejections by identifying issues before you present.
formula Four discrepancy checks:
LC Amount: $10,000.00, Tolerance: 2%
Invoice: $9,800.00 → within tolerance ✓
Latest Shipment: 2026-07-15, Actual: 2026-07-14 → on time ✓
Expiry: 2026-08-01, Presentation: 2026-07-20 → on time ✓
Required: Invoice, Packing List, Bill of Lading
Provided: Invoice, Packing List → Missing: Bill of Lading ✗
Result: Discrepancy Found — Bill of Lading missing
3. Incoterms Contextual Explainer
Why use it? Select an Incoterm to see exactly who owns risk and cost, and at what point.
Key benefit: No more confusion about who pays for what — clear, plain-English explanations.
EXW: Risk transfers to buyer at seller's premises. Buyer pays all transport, insurance, duties, and clearance. Maximum buyer responsibility.
FOB: Seller until loaded on vessel; buyer after. Seller pays loading costs; buyer pays freight, insurance, and destination costs.
CIF: Seller pays freight and insurance to destination, but risk still transfers at loading — a common confusion point.
DDP: Seller pays everything, including import duties. Maximum seller responsibility.
FCA: Seller until handed to buyer's carrier. Flexible for any transport mode.
4. Multi-Supplier Landed-Cost Normalizer
Why use it? Normalize competing supplier quotes into one true landed cost per unit — apples-to-apples comparison.
Key benefit: See which supplier is truly cheapest after all costs are factored in.
formula Landed Cost Per Unit = (Total Goods Cost + Freight + Insurance + Duty + Broker Fees) / Quantity
Supplier A: Unit price $8.00, Quantity 500, Freight $200, Insurance $50, Duty $100, Broker $25
Total goods: $4,000.00, Total landed: $4,375.00 → $8.75/unit
Supplier B: Unit price $7.50, Quantity 500, Freight $350, Insurance $75, Duty $100, Broker $30
Total goods: $3,750.00, Total landed: $4,305.00 → $8.61/unit
Supplier B is cheaper despite higher freight — the tool ranks them correctly.
5. Certificate & Document Requirement Checker
Why use it? A reference starting point for typically required documents by product category.
Key benefit: Quick reference for what documents to expect — but always verify with destination customs authorities.
Food / Agricultural: Phytosanitary Certificate, Certificate of Origin, Health Certificate
Electronics: Certificate of Origin, FCC/CE Compliance Doc, Commercial Invoice
Textiles / Apparel: Certificate of Origin, Commercial Invoice, Packing List
Chemicals: Safety Data Sheet (SDS), Certificate of Origin, Hazmat Declaration
6. ISF Deadline Tracker
Why use it? The 10+2 Importer Security Filing (ISF) is due 24 hours before vessel loading. Track your deadlines and get notifications.
Key benefit: Never miss an ISF filing deadline — notifications when you're within 24 hours.
formula Hours Until Deadline = (Vessel Loading Time - 24 hours) - Now
Vessel Loading: 2026-07-15 14:00
ISF Deadline: 2026-07-14 14:00 (24 hours prior)
Now: 2026-07-14 10:00 → 4 hours until deadline → Urgent
Now: 2026-07-14 16:00 → 2 hours overdue → Overdue
7. Supplier Business Registration Lookup Helper
Why use it? Verify a supplier's registration with an official registry, then log what you found.
Key benefit: A structured audit trail of your supplier verification checks — essential for due diligence.
architecture Safe by design: Links to official free registries (UK Companies House, US SEC EDGAR, Hong Kong Companies Registry) and logs your findings — no embedded database.
Supplier: "Acme Manufacturing Ltd."
Registration #: 12345678
Status: Verified (found in UK Companies House)
→ Logged with timestamp for your compliance records.

Common Mistakes to Avoid
Fix: The tool links to official government resources and logs your findings — it does NOT embed data. Always use the official tools for the actual screening, then log the result here.
Fix: The Certificate Checker is a reference starting point — always verify exact requirements with the destination country's customs authority or a licensed customs broker before shipping.
Fix: The audit trail is what makes these tools valuable for compliance. Log every check you perform.
- ⚠️ LC Checker: Enter tolerance as a percentage (e.g., 2 for 2%). The tool calculates the allowable variance automatically.
- ⚠️ Landed Cost: Use the actual exchange rate for the date of your quote — exchange rates fluctuate.
- ⚠️ ISF Tracker: The 24-hour deadline is strictly enforced — if you're overdue, file immediately.
- ⚠️ Registration Lookup: Different countries use different registry formats — use the correct official registry for each supplier.
Frequently Asked Questions
Does the Denied-Party Screener have its own sanctions list?
No — and that's by design. Sanctions lists change frequently, and a stale embedded list would be dangerous to rely on. The tool links directly to official government resources (Trade.gov Consolidated Screening List, OFAC Sanctions Search) and logs your audit trail for compliance recordkeeping.
How accurate is the Certificate Requirement Checker?
It's an illustrative reference starting point, not an exhaustive or guaranteed-current database. Different countries and specific product categories can have unique requirements — always verify exact requirements with the destination country's customs authority or a licensed customs broker before shipping.
Does this connect to any customs system or broker platform?
No. The International Trade Toolkit is a manual-entry tool. It doesn't connect to any customs system, broker platform, or live data feed. You review the information and log the findings — this suite structures that work into a consistent, auditable record.
What happens if I uninstall the extension?
All data (screening logs, LC checks, supplier comparisons, ISF shipments, registration logs) is removed from your browser. If you have a Pro license, you can re-enter your key after reinstalling to restore access.
