For a comprehensive reference, explore our complete shipping terms and definitions guide.
What Are Incoterms and Why Do They Matter for Shipping?
Incoterms (International Commercial Terms) are 11 standardized trade rules published by the International Chamber of Commerce that define buyer and seller responsibilities in international shipping contracts. Updated every 10 years, the current Incoterms 2020 edition governs who pays for shipping, handles customs clearance, and assumes liability risk during transit.
The most commonly used Incoterms in ecommerce include:
- Ex Works (EXW) — Seller makes goods available at their premises; buyer handles all shipping and customs
- Free on Board (FOB) — Seller delivers goods to the carrier at origin; buyer assumes risk after loading
- Cost, Insurance and Freight (CIF) — Seller pays shipping and insurance to destination port; buyer handles import customs
- Delivered Duty Paid (DDP) — Seller handles all costs and risks until goods reach buyer’s location
For small businesses using platforms like ParcelPath for discounted UPS and USPS rates (60-89% off retail), understanding these terms helps determine who’s responsible for shipping costs, insurance claims, and customs delays.
How Do FOB Shipping Terms Work?
Free on Board (FOB) terms specify exactly when ownership and liability transfer from seller to buyer during shipping. FOB Origin means the buyer assumes responsibility once the carrier picks up the package, while FOB Destination keeps the seller liable until delivery.
- FOB Origin/Shipping Point — Buyer pays freight costs and assumes risk after pickup
- FOB Destination/Delivered — Seller pays freight and retains risk until delivery
- FOB Airport/Port — Transfer occurs at the specified transportation hub
| FOB Term | Who Pays Shipping | Risk Transfer Point | Best For |
|---|---|---|---|
| FOB Origin | Buyer | At pickup | Large volume buyers with carrier contracts |
| FOB Destination | Seller | At delivery | Small orders, retail customers |
| FOB Port/Airport | Split responsibility | At named location | International shipments |
How Do Dimensional Weight and Billable Weight Affect Shipping Costs?
Dimensional weight (DIM weight) is a pricing method that calculates shipping costs based on package size rather than actual weight, using the formula: Length × Width × Height ÷ DIM Factor. UPS and FedEx use a DIM factor of 139 for domestic shipments, while USPS uses 166 for Priority Mail. For more details on how to calculate these properly, visit our guide on measurements and calculations.
Starting in 2026, carriers have implemented stricter dimensional weight policies:
- FedEx now rounds all package dimensions up to the nearest inch
- UPS Additional Handling Surcharge applies to packages over 10,368 cubic inches
- Oversize charges kick in for packages exceeding 17,280 cubic inches
Billable weight is always the greater of actual weight or dimensional weight. For example, a 2-pound package measuring 20″ × 16″ × 12″ has a dimensional weight of 28 pounds (20×16×12÷139), so you’d pay for 28 pounds of shipping.
What Are the Most Common Shipping Surcharges in 2026?
Peak season surcharges, delivery area fees, and additional handling charges are the three most expensive shipping surcharges affecting ecommerce businesses. Peak season fees were in effect from October 5, 2025 through January 18, 2026, with some surcharges increasing over 25% compared to 2024.
| Surcharge Type | When Applied | 2026 Cost Range | How to Avoid |
|---|---|---|---|
| Peak Season | October-January | Varies by package | Ship before/after peak dates |
| Delivery Area | Rural/remote ZIP codes | Varies by package | Use USPS for rural areas |
| Additional Handling | Oversized/irregular packages | Varies by package | Keep packages under size limits |
| Fuel Surcharge | All shipments | 8.75%-12.25% of base rate | Cannot avoid, built into pricing |
What Freight Forwarding Terms Should Ecommerce Businesses Know?
Freight forwarders are licensed logistics specialists who arrange transportation, handle customs documentation, and coordinate international shipments on behalf of importers and exporters. They act as intermediaries between shippers and carriers, leveraging volume discounts and expertise to optimize shipping routes and costs.
Essential freight forwarding terminology includes:
- Bill of Lading (BOL) — Legal contract between shipper and carrier specifying goods, terms, and delivery instructions
- Multimodal Transportation — Using two or more transport modes (truck, rail, ocean, air) in a single shipment

What Are Air Freight and Express Shipping Terms?
Air freight refers to cargo transported by aircraft, typically used for time-sensitive, high-value, or lightweight shipments that require faster delivery than ocean or ground transport. Air cargo rates are calculated using chargeable weight, dimensional weight factors, and fuel surcharges that fluctuate with jet fuel prices.
Key air freight concepts include:
- Chargeable Weight — Higher of actual weight or volumetric weight (Length × Width × Height ÷ 6000 for air freight)
- Consolidated Service — Multiple shipments combined into one aircraft load to reduce costs
- Direct Service — Dedicated aircraft space for faster, more expensive shipping
- Express Shipping — Premium air service guaranteeing next-day or 2-day delivery with tracking

What Ocean Freight and Maritime Shipping Terms Matter Most?
Ocean freight terminology centers around port operations, container specifications, and shipping documentation required for international maritime transport. Understanding these terms helps businesses navigate the complex world of international trade and avoid costly mistakes.
What Are the Key Port and Vessel Terms?

Frequently Asked Questions
What’s the difference between freight and parcel shipping?
Freight shipping handles heavy cargo over 150 pounds using trucks, trains, or ships, while parcel shipping covers lightweight packages under 150 pounds via courier services like UPS, FedEx, and USPS. Freight requires specialized equipment and documentation, while parcels use standardized packaging and delivery methods.
When do shipping rates typically increase each year?
Major carriers implement General Rate Increases (GRIs) in December/January each year, with additional mid-year surcharge adjustments occurring in July and October. USPS rates increased 6.6% for Priority Mail in January 2026, while UPS and FedEx both implemented 5.9% average increases.
What does “delivered duty paid” mean for international shipping?
Delivered Duty Paid (DDP) means the seller pays all costs including shipping, insurance, customs duties, and taxes until goods reach the buyer’s location. This Incoterm places maximum responsibility on the seller and provides cost certainty for international buyers.
How do I calculate dimensional weight for my packages?
Calculate dimensional weight by multiplying Length × Width × Height (in inches) and dividing by the carrier’s DIM factor: 139 for UPS/FedEx domestic shipments, 166 for USPS Priority Mail. Your billable weight is the higher of actual weight or dimensional weight.
What’s the difference between ETA and ETD in shipping?
ETA (Estimated Time of Arrival) is when a shipment is expected to reach its destination, while ETD (Estimated Time of Departure) is when it’s scheduled to leave the origin facility. These timestamps help businesses plan inventory, customer communications, and warehouse operations.
