Why Is Knowing the Terms Important?
The world of international shipping has its own terminology. Concepts such as Incoterms, dimensional weight, HS code and proforma invoice may seem complex at first glance; however, understanding these terms is the foundation of managing the shipping process correctly and controlling costs. Knowing the terms gives you confidence in carrier and customs processes.
A misunderstood term can lead to serious costs and delays. For example, incorrectly determining the delivery term (Incoterms) can cause you to face unexpected customs duty or shipping costs. Correct terminology clarifies responsibilities between parties and prevents disputes.
For e-commerce sellers and exporters, these terms are part of daily operations. Using a common language in communication with customers, carriers and customs administrations speeds up processes and leaves a professional impression. Mastering the terminology provides a competitive advantage.
This glossary explains the terms you will most frequently encounter in international shipping in plain language. By addressing each term with practical examples, it offers a resource you can use in your daily operations rather than one that stays in theory. This way you can manage your shipments more consciously and safely.

Delivery and Payment Terms
Incoterms (International Commercial Terms) are standard rules that define the responsibilities, costs and risks between the seller and buyer. Set by the International Chamber of Commerce, these rules clarify which party will bear the shipping, insurance, customs and tax costs.
DDP (Delivered Duty Paid) is the delivery term in which the seller bears all costs (shipping, customs duty, taxes) and delivers the product to the buyer's door. It is the most comfortable option for the buyer because they make no additional payment at delivery. It is often preferred in e-commerce for customer satisfaction.
DAP (Delivered at Place) is the delivery term in which the seller delivers the product to the designated place but the buyer pays the customs duty and import taxes. Other Incoterms such as FOB, CIF and EXW also define responsibility and cost sharing in different ways. Choosing the right term prevents surprises.
A proforma invoice is a preliminary document prepared before the sale, showing the product's price and conditions. The commercial invoice is the official document issued after the sale. A letter of credit is a secure payment method in which the bank guarantees payment and provides trust in international trade.
Weight and Measurement Terms
Dimensional weight is the weight calculated based on the volume a shipment occupies. Carriers compare the actual weight with the dimensional weight and use whichever is greater as the basis for pricing. That is why dimensional weight comes to the fore for light but large packages. Dimensional weight is usually found by dividing the product of width x length x height (cm) by a divisor.
Actual weight (gross weight) is the physical weight of the shipment on the scale together with its packaging. Net weight is the weight of only the product, excluding packaging. Correctly stating this distinction on the invoice and documents is important in customs and transport calculations.
Chargeable weight is the weight the carrier uses in the fee calculation and is the greater of the actual weight and the dimensional weight. Knowing this concept is critical to understanding shipping cost; packaging optimization directly affects this weight.
Container measurements are also important terms in sea freight. FCL (Full Container Load) means a full container load; LCL (Less than Container Load) means partial load sharing a portion of the container. For small-volume shipments, LCL is more economical than renting a container alone.

Customs and Tax Terms
The HS code is a code system in which products are classified according to an international standard. Every product has an HS code, and this code determines the customs duty rate, the restrictions to be applied and the import rules. Using the correct HS code is critical for the customs process to proceed smoothly.
Customs duty is a tax applied to imported products and is usually calculated on the value of the product. VAT (value-added tax) is a consumption tax applied to imported products in many countries. These taxes are paid by the seller or buyer according to the delivery term (DDP/DAP).
IOSS (Import One-Stop Shop) is a system that enables VAT to be collected at the time of sale for e-commerce shipments below a certain value in the European Union. Using IOSS provides fast processing at customs and prevents the buyer from facing surprise costs at delivery.
ETGB (Electronic Trade Customs Declaration) is a simplified declaration type used in Türkiye for shipments within the scope of micro export. This document facilitates small-scale export and offers advantages such as VAT refund. A certificate of origin is a document that certifies the country where the product was produced and provides a tax advantage in some countries.
Operation and Tracking Terms
A tracking number is a unique code assigned to each shipment. With this number you can monitor in real time which stage your shipment is at. Tracking provides transparency for both the sender and the buyer and increases customer satisfaction.
Consolidation is the process of combining multiple small shipments into a single large shipment. This method lowers the cost per unit and is an economical solution, especially for businesses that ship frequently. Consolidated shipments increase transport efficiency.
POD (Proof of Delivery) is the document that proves delivery has taken place; it usually includes the buyer's signature or a delivery photo. This document forms important evidence in delivery disputes. Last-mile delivery is the final stage in which the shipment is delivered from the distribution center to the buyer's address.
Warehouse and fulfillment terms are also important in e-commerce. Fulfillment covers the process of storing, packing and shipping products. Services such as Amazon FBA carry out this process on behalf of the seller. Knowing these terms helps you plan your logistics operation correctly.

Conclusion: Common Language, Smooth Trade
Mastering international shipping terms lets you manage your shipping process more consciously and safely. Knowing these concepts, from Incoterms to HS code, from dimensional weight to IOSS, helps you both control your costs and prevent possible problems.
Although terminology may seem complex at first, each term actually exists to clarify a part of the process. Over time these terms become a natural part of your daily operations and strengthen your communication with carriers, customs and customers.
