Selling internationally is one of the fastest ways to grow a US-based business. But the logistics of actually getting your product from a warehouse in Chicago or Los Angeles to a customer in Germany, Australia, or Brazil can feel overwhelming the first time. Customs declarations. Harmonized codes. Commercial invoices. Incoterms. The terminology alone is enough to make most business owners stick to domestic shipping. This guide demystifies the entire process — step by step — so your first international shipment goes smoothly.
Step 1: Classify Your Products with the Correct HTS Code
Every product shipped internationally must be assigned a Harmonized Tariff Schedule (HTS) code — a standardized 10-digit number used by US Customs and Border Protection (CBP) to classify goods for export, and by foreign customs authorities to determine import duties on the receiving end.
Getting your HTS code wrong is one of the most expensive mistakes a new international shipper can make. An incorrect classification can result in shipment delays, customs holds, costly amendments, and potential fines. It can also cause your customer to be charged the wrong import duty rate, which damages the relationship.
Step 2: Understand Export Controls and Licensing Requirements
Not everything can be freely exported from the United States. The Bureau of Industry and Security (BIS) administers the Export Administration Regulations (EAR), which control the export of commercial and dual-use goods. Separately, the State Department’s Directorate of Defense Trade Controls (DDTC) regulates military and defense-related items under the International Traffic in Arms Regulations (ITAR).
Most everyday commercial products — clothing, food, standard electronics, consumer goods — do not require a specific export license and can be shipped under a general license designation (EAR99). However, if your product has potential military, nuclear, chemical, or surveillance applications, you may need to apply for a specific export license before shipping.
Smart Delivery’s in-house export compliance team screens every international shipment against the US Denied Persons List, Debarred Parties List, and OFAC sanctions database before release — protecting our clients from inadvertent violations.
Step 3: Prepare Your Export Documentation
International shipments require a package of documents that varies slightly by destination country, product type, and value — but the core set is consistent. Here is what you will typically need:
- Commercial Invoice: Itemized list of goods, their value, country of origin, buyer and seller details, and payment terms. This is the primary document used by customs authorities worldwide.
- Packing List: Detailed breakdown of what is in each box or pallet — quantities, weights, and dimensions. Required by most carriers and customs authorities.
- Bill of Lading (air) or Airway Bill (AWB): The contract between shipper and carrier, and the document that releases the goods to the consignee at destination.
- Electronic Export Information (EEI) via AES: Required for shipments valued over $2,500 or controlled items. Filed through the Automated Export System (AES) at the US Census Bureau.
- Certificate of Origin: Certifies the country where goods were manufactured. Required by many countries to determine applicable tariff rates, especially for preferential trade agreements.
- Dangerous Goods Declaration: Required if your shipment contains lithium batteries, chemicals, flammable items, or other IATA-regulated dangerous goods.
Step 4: Choose the Right Incoterms for Your Sale
Incoterms (International Commercial Terms) are 11 standardized trade terms published by the International Chamber of Commerce that define exactly where the seller’s responsibility ends and the buyer’s responsibility begins in a cross-border transaction. Choosing the right Incoterms is critically important — it determines who pays for freight, insurance, and import duties, and who bears the risk if goods are damaged or lost in transit.
The two most commonly misunderstood Incoterms for e-commerce and direct-to-consumer international shipping are DAP (Delivered at Place) and DDP (Delivered Duty Paid). Under DAP, the buyer is responsible for paying import duties and taxes upon arrival — which can lead to surprise charges and refusals to pay. Under DDP, the seller pays all duties and delivers a fully cleared, duty-paid shipment to the customer’s door. DDP creates a far better customer experience but requires the seller to have a mechanism for calculating and prepaying import duties.
Step 5: Select Your Shipping Mode and Service Level
For most B2C international shipments under 150 kg, international express air freight (FedEx International Priority, DHL Express, UPS Worldwide Express) is the standard choice, offering 1–5 business day transit times to most major markets. For larger commercial shipments, economy air freight offers 5–10 business day service at meaningfully lower rates.
Ocean freight is the cost-effective choice for heavy, bulky, or non-time-sensitive shipments. A full container (FCL) from Los Angeles to Hamburg takes approximately 25–30 transit days. LCL consolidation adds roughly 5–7 days for the consolidation and deconsolidation process at origin and destination ports.
Step 6: Navigate Destination Country Customs
Even with perfect documentation, international shipments can be held at customs for additional inspection or queries. The most common causes of customs delays are: incorrect or missing commercial invoice details, undervalued shipments (customs fraud), prohibited or restricted products, and missing or incorrect certificates of origin.
Working with an experienced freight forwarder like Smart Delivery ensures your documentation is prepared to the standard required by each destination country before the shipment departs — dramatically reducing the risk of costly holds or returns.
