The ultimate guide to Time Definite Express (TDX) by DHL

Speed and reliability define success in today’s fast-moving world of trade. As Sri Lanka continues to strengthen its position as a regional logistics hub, local businesses face growing pressure to deliver with precision — not just quickly, but exactly when promised.

Whether you’re shipping garments to Europe, exporting premium Ceylon tea to the Middle East, or sending documents to a global partner, every minute matters. Time is money, and any delays in border clearance can reduce processing efficiency by as much as 40%.¹

That’s where DHL Express Time Definite International (TDX) services come in. Designed for shipments that demand certainty, DHL’s TDX options guarantee delivery by a specific time of day, helping Sri Lankan businesses meet deadlines, build trust, and gain a competitive edge in the global e-commerce marketplace.

What is Time Definite Express (TDX) delivery?

Time Definite Express is a premium international courier service that ensures shipments are delivered within a precise time window. TDX DHL services provide an additional layer of predictability as it’s built around a guaranteed delivery time, making it ideal for critical shipments that can’t afford uncertainty.

This service benefits both businesses and customers. For exporters, time-sensitive delivery can mean the difference between closing a major deal or missing a retail season. For customers, it ensures that important documents or parcels arrive exactly when expected. The precision of TDX helps businesses manage their schedules confidently, reduce risk, and streamline operations across borders.

How DHL’s TDX services work

DHL Express offers several time-specific delivery options, allowing businesses to choose the delivery window that best suits their needs.

DHL Express 9:00

This service provides early-morning delivery to key global business centers in Europe, the United States, and parts of Asia-Pacific. It’s ideal for urgent shipments such as legal contracts, confidential tenders, or medical samples that must arrive before the business day begins.

DHL Express 10:30

Perfect for businesses that need reliable timing for international meetings, financial transactions, or critical spare parts, DHL Express 10:30 guarantees mid-morning delivery. It gives exporters peace of mind knowing that their partners will receive shipments during active business hours.

DHL Express 12:00

This timed delivery service is well-suited for e-commerce sellers and general businesses that require consistent timing without the premium of earlier delivery windows.

Each service is backed by DHL’s global air network and comes with a flat-rate additional charge for both documents and non-documents. Customers can also track every shipment in real time using DHL’s digital tools, ensuring full transparency and accountability from pickup to delivery.

Why timed deliveries matter for Sri Lankan businesses

Sri Lanka’s economy relies heavily on import and export activity, with key industries such as coffee, tea and spices shipping directly from plantations. In fact, in 2024, coffee, tea and spices made up 1.3% of Sri Lanka’s total exports, accounting for a total value of $1.84 billion.² At such a value, delivery timing can make or break business relationships and reputation.

Tea exporters depend on fast and precise deliveries to preserve product freshness and meet retailer expectations. A delayed shipment could result in quality degradation, reduced value, or missed shelf dates. Apparel manufacturers work with strict retail seasons and collection launches, especially for buyers in the United States and Europe. Time definite shipping ensures they never miss deadlines tied to fashion cycles or store openings.

E-commerce sellers also benefit greatly from guaranteed delivery times. In a global marketplace where customers value speed and reliability, being able to commit to specific delivery times can set Sri Lankan sellers apart from competitors. Reliable logistics isn’t just about speed; it’s about enabling business continuity and building customer trust, especially for overseas buyers expecting punctual, trackable service.

Preparing your parcels for shipment

To make the most of DHL’s TDX service, preparation is essential. Following these steps ensures a smooth customs clearance process:

1. Weigh and measure your shipment: Always provide accurate dimensions and weight to avoid re-invoicing or clearance delays. Under-declared weight or size can cause processing issues and result in delays.
2. Prepare the waybill: The waybill serves as your shipment’s identity. It should include complete sender and receiver details, shipment description, and the service option selected (for example, DHL Express 10:30).
3. Prepare the invoice: Every international shipment requires a commercial or pro forma invoice. Clearly describe the contents, their value, and purpose — whether for sale, sample, or personal use.
4. Verify destination regulations: Each country has its own import restrictions and documentation requirements. Ensure your shipment complies with all customs and export regulations to prevent delays at borders.
5. Package carefully: Use sturdy boxes and secure cushioning to protect the contents. Proper packaging not only prevents damage but also supports a smooth delivery experience.

By following these steps, Sri Lankan businesses can save time, ensure customer satisfaction, and take full advantage of DHL’s international parcel service.
