Courier Restrictions Explained: What You Need to Know Before Shipping

Ever tried to send a package and hit a surprise roadblock? Most of the time it’s a courier restriction you didn’t see coming. Whether you’re a casual sender or a small business, knowing the rules can save you time, money, and a lot of headaches.

Common Items That Couriers Won’t Take

Almost every courier has a list of prohibited goods. The most common bans include hazardous materials (like gasoline, fireworks, or chemicals), perishable foods without proper packaging, and high‑value items such as cash or precious metals unless you use a specialized service. Some companies also restrict electronic cigarettes, large batteries, and certain medicines. Before you pack, check the courier’s prohibited‑item list on their website – it’s usually a simple PDF or FAQ.

Size, Weight, and Documentation Limits

Even if your item is allowed, you can still run into trouble if it’s too big or heavy. Most couriers cap packages at around 150 cm in any dimension and 30 kg in weight for standard services. Oversized or overweight parcels often need a freight quote instead of a regular parcel rate. Additionally, international shipments require customs paperwork, accurate declared values, and sometimes special permits (think for drones or medical devices). Missing or incorrect docs can delay your delivery or cause the package to be sent back.

Here’s a quick checklist to keep things smooth:

  • Confirm the item isn’t on the prohibited list.
  • Measure and weigh the package; stay within the courier’s standard limits.
  • Gather required documents: commercial invoice, export license, or special permits.
  • Label the package clearly, including any handling instructions.
  • Use the courier’s online calculator to verify that the shipment meets all criteria.

Skipping any of these steps often means the courier will call you, charge extra fees, or simply refuse pickup.

Another piece many people forget is the “restricted zones” rule. Some couriers won’t deliver to certain remote or conflict‑affected areas, or they may require a higher‑priced “remote area surcharge.” If you’re sending to a location outside the standard service map, double‑check that the courier actually covers it.

If you’re dealing with a fragile or high‑value item, consider adding insurance or opting for a specialized courier that handles such shipments. The added cost is usually worth the peace of mind.

Finally, remember that each courier can update its policies without much notice. Subscribe to their newsletters or set up alerts in your account so you’re always aware of the latest changes. Staying informed is the cheapest way to avoid costly surprises.

By keeping these restrictions in mind, you’ll ship smarter, avoid delays, and keep your customers happy. Got a specific question about an item you’re trying to send? Drop a comment and we’ll help you sort it out.
