Before comparing couriers, keep these variables in mind:
If you’re researching “shipping from Ireland to us”, your main questions are usually: How much will it cost? How long will it take? How do I track it?
Track.Global helps you answer all three:
Rates and transit times can change. A calculator is the easiest way to get a current, comparable estimate across carriers and service levels.
Both can work well — but they’re built for different priorities.

Tip: If your shipment is business-critical, the priority tier is often worth it for fewer “in-transit surprises.”
Customs is where many delays happen — not because shipping is “slow,” but because the parcel needs clear information.
If you’re shipping through postal channels, you’ll typically need a customs declaration for shipments leaving the EU. Ireland’s postal operator provides common forms such as:
Always include:
US import rules can change. As of late 2025, the US has moved away from broad duty-free treatment for many low-value shipments, so duties may apply more often than people expect.
For gifts, a common rule of thumb is:
What this means for you:
If your parcel is a gift or e-commerce shipment, set expectations with the recipient: delivery may pause until duties/taxes are paid.
International shipments often move through multiple checkpoints (export, airline linehaul, import customs, domestic delivery). Tracking is easiest when you don’t have to jump between carrier sites.
With Track.Global you can:
It depends on the service level. Express courier options can be 1–3 business days in many lanes, while postal options are commonly 6–10 business days or more depending on processing and customs.
Usually an economy/postal tier is cheaper for lightweight parcels, but pricing depends heavily on size, weight, and delivery zone. Use a calculator to compare real options side-by-side.
In most cases, yes — especially with FEDEX_INTERNATIONAL_PRIORITY. USPS can be competitive on cost, but premium courier networks are designed for speed and time-definite delivery.
Often the recipient pays on arrival unless your shipping arrangement explicitly includes duties (DDP). If duties are due, delivery can pause until payment is made.
If you’re deciding between shipping from Ireland to US with USPS or FedEx, start with the Track.Global delivery calculator to compare estimated cost + delivery time, then track your parcel end-to-end.
Enter the from/to country and postal codes, choose a category, add weight and dimensions (L×W×H), select carriers (e.g., USPS/UPS/FedEx/DHL), then click Calculate. You can sort results by cost or by delivery time and switch currency (USD/EUR).
For the best shipping quote, use:<br /> - Origin + destination postal/ZIP codes<br /> - Weight including packaging<br /> - Box dimensions (length, width, height)<br /> - Shipment type/category (especially helpful for international or restricted goods)
Yes. Select multiple couriers to get a shipping price comparison in one results list and quickly see which carrier/service wins on price or speed.
Both. Carriers often bill by the greater of actual weight or dimensional (volumetric) weight. Small/heavy parcels usually price by weight; large/light boxes can price by dimensional weight.
Dimensional weight reflects the space your box takes up. If your package is bulky, carriers may charge more even if it’s light—so accurate dimensions are key for a reliable shipping rate estimate.
Yes—results typically include service options plus an estimated delivery window. Use sorting by delivery time to find the fastest shipping quote.
They’re estimates based on the details you enter and current carrier pricing. Final charges can differ if the carrier measures a different weight/size, applies residential/remote/oversize surcharges, or updates rates.
Flat Rate can be cheaper when your item is dense/heavy but fits in a Flat Rate box/envelope. By-weight is often cheaper for light parcels, especially to nearby zones—compare both for the best shipping cost.
Yes. Choose the destination country (and postal code when available), then compare international services across carriers. Keep in mind that customs rules and service availability depend on destination and item type.
Shipping rates usually cover transport/postage only. Duties/taxes (international) are typically not included, and your own handling/packaging fees depend on your business process—add those separately if you’re calculating total landed cost.
