Commercial Invoice for IWSC Entry

A Commercial Invoice is the primary customs document used for the import and export of goods. When filing an entry with the International Warehouse and Storage Consortium (IWSC), the invoice must satisfy specific formatting and content requirements to avoid delays, penalties, or clearance rejections. This page explains what an IWSCcompliant commercial invoice should contain, how to prepare it, and common pitfalls to watch.

Why the Commercial Invoice Matters for IWSC

IWSC operates a network of bonded warehouses and distribution centers across the United States. Because goods move through IWSC facilities before reaching the final consumer, customs authorities rely on the commercial invoice to verify:

• Correct classification (HS tariff code)
• Accurate valuation for duty calculation
• Country of origin and any preferential trade agreements
• Legal ownership and responsibility for the shipment

Any missing or inaccurate information can trigger an Entry Summary hold, leading to additional inspections and increased storage fees.

Essential Elements of an IWSCReady Invoice

The invoice must be clear, legible, and presented in English. The following table lists every field that customs and IWSC expect to see.

Formatting Tips

• Font: Use a standard, readable font (Arial, Times New Roman) at 1012pt.
• Paper Size: 8.511in (US Letter) or A4 if the importer prefers.
• Language: English only; translations may be attached but do not replace the English version.
• Electronic Submission: PDFs are accepted; ensure the file is searchable (OCR enabled) and the size does not exceed 5MB.
• Barcode/QR Code: Not required by customs, but IWSC often requests a barcode that contains the invoice number for internal tracking.

StepbyStep Preparation Process

1. Gather Source Documents Purchase orders, packing lists, product specifications, and the sellers export license.
2. Determine HS Codes Use the official U.S. HTS database or a licensed customs broker to verify each items classification.
3. Calculate Values Add unit price quantity, then add freight, insurance, and any other charges. Ensure the total matches the amount declared on the entry form.
4. Complete the Invoice Template Fill every required field, doublechecking spelling of country names and numerical accuracy.
5. Attach Supporting Documents Packing list, certificate of origin, and any required licenses should accompany the invoice when submitted to IWSC.
6. Obtain Signature The sellers authorized signatory must sign before the document is scanned.
7. Submit to IWSC Upload through IWSCs online portal or email the PDF to the assigned customs liaison.
8. Confirm Receipt Request a confirmation number from IWSC; keep it for future reference and for the customs entry filing.
