International Shipping Guide

This guide answers common questions about international shipping documentation, Incoterms, HS codes, customs delays, and commercial invoices. Use it as a starting point, then dive deeper into specific topics as needed.

International shipping involves multiple documents, regulations, and processes that can feel overwhelming. Customs requirements vary by country. Carriers have different format expectations. Missing one detail can delay your shipment for days. Shipments above the de minimis threshold are subject to import duties and must clear customs before delivery.

Core Shipping Concepts

Incoterms

Incoterms define who pays for shipping costs and who bears the risk during transport. They're standardized terms used in international trade contracts.

Common Incoterms include EXW (seller makes goods available at their location), FOB (seller delivers to port, buyer handles shipping), CIF (seller pays shipping and insurance to destination port), DAP (seller delivers to destination, buyer handles import), and DDP (seller handles everything including duties and taxes).

Choosing the right Incoterm affects your invoice. It determines who's responsible for costs and risks at each stage of the shipment. Get it wrong, and you may face disputes or unexpected charges.

Commercial Invoice vs Pro Forma Invoice

These two invoice types serve different purposes. A Commercial Invoice records the final transaction and shipment details used for customs valuation and payment records. Its legal effect depends on the contract and applicable law.

A Pro Forma Invoice is preliminary. It's used for quotes, import permits, letters of credit, or sample shipments. It may contain estimates rather than final values.

Using the wrong type causes problems. Customs may reject a Pro Forma when they need a Commercial Invoice. Sending a Commercial Invoice for samples can confuse buyers about payment expectations.

HS Codes & Product Classification

The Harmonized System provides a six-digit international product classification. Importing countries can require additional tariff digits for the customs declaration.

The first six digits are standardized internationally, while destination extensions vary in length. An incorrect classification can affect duties, admissibility, or processing.

Finding the right code requires understanding your product's primary function, material, and intended use. Generic codes like "9999" or "other" often trigger customs holds for clarification.

Country of Origin

Country of origin means where the goods were manufactured, not where they're shipping from. This matters because customs uses it to determine duty rates, verify trade agreements, and check compliance with import restrictions.

If you're shipping from a warehouse in Country A, but the goods were made in Country B, the origin is Country B. Getting this wrong can result in incorrect duty calculations or customs holds.

Common Customs Issues

Documentation is one source of avoidable carrier and customs questions. Common issues include:

  • Missing or incorrect tax IDs: Include the appropriate party's EIN, VAT, EORI, or other identifier when the procedure requires it.
  • Vague product descriptions: "Electronics" or "clothing" aren't specific enough. Customs needs detailed descriptions to classify goods correctly.
  • Wrong HS codes: Misclassified products lead to incorrect duty calculations. Customs may hold shipments to verify the correct classification.
  • Incomplete line items: Missing quantities, values, or country of origin for individual items causes delays. Every item needs complete information.
  • Incorrect Incoterms: Wrong Incoterms misrepresent who pays for shipping and duties, leading to disputes and incorrect duty assessments.
  • Missing signatures: Some routes or declarations require a signature, while eligible electronic-document workflows may not require a handwritten original.
  • Submission mismatches: Carriers use different paper and electronic-document workflows. Follow the instructions for the selected service.

Reviewing these details can reduce avoidable follow-up. A packing list can also help reconcile package contents, but it does not replace any required declaration or guarantee faster clearance.

How DocInvo Fits In

Tools like DocInvo organize common invoice fields in a structured form. The generated layout is not a substitute for a carrier-specific form or destination declaration when one is required.

Having all required fields in one place makes it easier to ensure nothing is missing. You can see what's mandatory versus optional, which helps prevent incomplete invoices.

The goal isn't to eliminate all customs delays—some are outside your control—but to minimize the documentation errors that cause preventable holds. A properly formatted invoice with complete information gives your shipment the best chance of clearing customs smoothly.
