When things go wrong, customers feel it fast. **Delays, unexpected charges**, or customs issues can quickly damage trust in your brand. If you’re new to selling internationally, getting the basics right early will save you time, money, and lost revenue in the long run. When done well, cross-border delivery becomes a competitive advantage. Fast, transparent delivery builds trust, boosts conversions, and encourages repeat purchases — all while improving your operational efficiency behind the scenes. [\#](#content-so-what-should-you-watch-out-for "Permalink")So, what should you watch out for? --------------------------------------------------------------------------------------------- At SAMOS, our international shipping specialists see the same issues come up time and time again. Here are the top **10 mistakes e-commerce businesses commonly make** when shipping internationally — and how to avoid them. **TIP:** If you’re at the very early stages of selling abroad, you may also find our guide [**cross-border shipping made simple for ecommerce brands**](https://samos-e.com/blog/e-commerce/cross-border-ecommerce-explained-a-simple-guide-for-growing-brands) **1. Not Shipping Delivered Duty Paid (DDP)** One of the biggest friction points in cross-border ecommerce is unexpected costs at delivery. When you don’t ship [**Deliver Duty Paid**](https://samos-e.com/resources/what-is-delivery-duty-paid), customers are often hit with surprise customs duties, taxes and handling fees. This creates a poor delivery experience and significantly increases the likelihood of refused shipments and returns. Offering DDP shipping ensures customers see the full landed cost upfront, improving conversion rates and customer satisfaction. **2. Incorrect or Non-Compliant HS Codes** [**Harmonised System**](https://samos-e.com/resources/what-is-an-hs-code) (HS) codes are essential for calculating the correct import duties and taxes. Using incorrect or non-compliant HS codes — especially for markets like the U.S. — can lead to delays, penalties, or incorrect charges. This doesn’t just impact your margins; it can also harm your reputation with both customers and customs authorities. Ensuring your HS codes are accurate and up to date is critical for smooth customs clearance. **3. Not Charging Import Duties and Taxes at Checkout** Failing to calculate and collect [**import duties and taxes**](https://samos-e.com/resources/duties-and-taxes) at checkout creates uncertainty for customers. Today’s international shoppers expect full transparency on [**total landed costs**](https://samos-e.com/blog/e-commerce/landed-cost-explained-for-ecommerce-global-shipping) before they buy. If these charges aren’t shown upfront, customers may abandon their carts or refuse delivery when unexpected fees arise. Integrating duty and tax calculation into your checkout for each destination country is now essential for cross-border ecommerce success. **4. Declaring Gross Instead of Net Value** A common mistake in customs documentation is declaring the gross price (including VAT or sales tax) instead of the net value. Customs authorities typically require the net transaction value. Getting this wrong can result in overpaid duties, shipping delays or compliance issues. Accurate customs valuation helps you avoid unnecessary costs and keeps shipments moving smoothly. If this is something you struggle with, you may find our [**net value calculator**](https://samos-e.com/blog/e-commerce/how-to-reduce-import-duties-and-avoid-paying-tax-on-tax) useful to ensure your declarations are correct from the start. **5. Not Offering Buy Now, Pay Later (BNPL) Options** Payment flexibility is increasingly important in global e-commerce. Not offering Buy Now, Pay Later (BNPL) options — such as [**Klana**](https://www.klarna.com/uk/) — can limit your ability to convert international customers. BNPL options reduce purchase friction, especially for higher-value cross-border orders, and can help increase the number of customers who complete a purchase in your most important markets. **6. Using Global Express Carriers Instead of B2C Specialists** Many e-commerce businesses default to global express carriers for international shipping. However, these networks were traditionally built for B2B deliveries — not high-density residential e-commerce shipments. As a result, brands often face higher costs, complex invoicing, and limited support when issues arise. Specialist cross-border e-commerce logistics providers offer more competitive rates, localised last-mile delivery solutions, and services designed specifically for online retail — helping improve both margins and customer experience. **7. Poor Product Data Setup in Ecommerce Platforms** Incomplete or inaccurate product data — such as missing SKUs, [**HS codes**](https://samos-e.com/resources/what-is-an-hs-code), or [**country of origin**](https://samos-e.com/resources/what-is-meant-by-country-of-origin) — can cause serious issues in cross-border fulfilment. Well-structured product data is essential for customs compliance, accurate duty calculation, and efficient shipping operations. Investing time in setting up your product listings properly will pay off in smoother international delivery. **8. Risky Product Descriptions That Trigger Inspections** Certain keywords in product descriptions can unintentionally trigger customs inspections. Words like “food,” “bullet,” “bomb,” or even “blood” (e.g. “bath bomb” or “blood orange”) can raise red flags. These inspections can lead to delays, additional costs, and a poor delivery experience. Using clear, neutral, and accurate product descriptions helps reduce the risk of unnecessary checks. **9. Lack of a Clear and Robust Returns Process** Returns are a key part of the ecommerce experience, especially in cross-border sales. If your returns process isn’t clear, easy to find, and simple to use, customers may hesitate to buy. [**A well managed international returns process**](https://samos-e.com/services/parcel-returns) builds trust, improves customer satisfaction, and increases repeat purchases. **10. Poor or Inadequate Packaging** Packaging plays a vital role in both protection and cost-efficiency. Insufficient packaging can lead to damaged goods, while oversized or inefficient packaging can lead to increased shipping costs. Using durable, right sized, and discreet packaging helps ensure safe, cost-effective, and reliable international deliveries. [\#](#content-faqs-cross-border-shipping "Permalink")FAQs: Cross-border shipping -------------------------------------------------------------------------------- **What is cross-border shipping in ecommerce?** Cross-border shipping refers to the process of selling and delivering products to customers in other countries. It involves international logistics, customs clearance, import duties, taxes, and local delivery. **Why is DDP shipping important?** [**Delivered Duty Paid (DDP)**](https://samos-e.com/resources/what-is-delivery-duty-paid) shipping ensures all duties and taxes are paid upfront. This prevents unexpected charges at delivery, improves customer experience, and reduces the risk of refused shipments. **How do I calculate import duties and taxes?** Import duties and taxes are typically calculated based on the product’s HS code, declared value, country of origin, and destination country regulations. Many ecommerce businesses use automated tools to calculate total landed costs at checkout. **What causes delays in international shipping?** Common causes include incorrect customs documentation, missing or inaccurate HS codes, unpaid duties and taxes, and customs inspections triggered by product descriptions. **In summary:** A successful cross-border ecommerce shipping strategy comes down to transparency, accuracy, and the right logistics setup. By avoiding these common mistakes, you can improve delivery performance, reduce costs, and create a better international customer experience. At SAMOS, we help you get it right from the start, so you can grow globally without losing customers along the way.
