Packaging instructions

Pack with care

Select the package according to the size of the object. Ensure that the package is durable and definitely undamaged. In addition, the item must withstand 4–5 times its own weight.

When packing your item as a parcel, try to make it as neat and flat as possible. Select a box of a suitable size for your item to prevent the contents from moving in the package. If necessary, use bubble wrap, styrofoam or foam plastic, for instance, to fill the box. Any packaging material causing sticking, and items of an irregular shape or round items may cause issues in mechanical handling. Cardboard and paper are the best materials for the outermost layer of a parcel or letter.

When you send your parcel through Posti you can use any packaging materials. You can also use pre-used materials as long as they are intact, durable for transport and there is no old address information on top of the parcel. Posti also offers a wide assortment of different packaging materials you can order from Posti’s online shop or buy from the nearest Posti's service point.

Sending and address labels

Place everything included in the shipment inside the parcel. Make the parcel an even shape and do not leave any flaps or protruding parts on your parcel. Use a sufficient amount of fixing materials, such as tape or string, to close the parcel. Leave enough space on the wrapping for the address label.

If you are reusing packaging materials, check the parcel to ensure there are no previous address markings or related bar codes that may cause problems in Posti’s sorting services.

Write your name, address and phone number, and the name, address and phone number of the recipient on the parcel. The Posti needs the sender’s information so that the parcel can be returned to the sender if the recipient does not pick it up. Address labels are now rarely used; you will only need to use an address label when sending parcels from the smallest Posti outlets.

Separate handling

Fragile items

Pack the product correctly for transport (use, for instance, cardboard, bubble wrap or paper as a filler) and mark the shipment clearly with stickers or tape if the product is fragile. Buying the Fragile supplementary service ensures the correct handling of the product.

Sending liquids and powders

If the item is susceptible to leaking, send it as a fragile item. Send any liquids in a leak-proof container or bottle. Pack containers with large openings, such as buckets containing berries, in plastic bags. Tape or tie the bag so that it is waterproof. Pack containers holding liquid in a durable box and make sure they cannot move around in the box. The packaging must contain some type of absorbent filler to prevent any leaks from broken containers or bottles from spreading. We recommend the Fragile additional service for sending liquids.

Sending laboratory samples

Laboratory samples are transported in Finland as letters, reply mail items, parcels or freight, for example. Special Handling supplementary service must be chosen for laboratory samples sent as parcels. The shipment is delivered for transport by taking it to Posti's service point or ordering a pick-up from the desired location. Samples must not be dropped off in a mailbox, and they may not be dead animals.

Samples categorized with the code UN 3373 are not viable for air traffic as postal items due to aviation legislation. For this reason, they cannot be sent as postal items internationally, and the service level for domestic transport cannot be guaranteed over long distances.

Electrical appliances and electronics

Always use a package that is suitable for the size, weight and durability of the product. The manufacturer’s packaging is usually not suitable for transport. With antistatic materials you can prevent electronic parts from being damaged. We recommend the Fragile additional service for sending electrical appliances and electronics.

Sharp objects

Carefully cover any blades and sharp points to ensure they do not harm the employees handling the item or damage other items. Ensure that any sharp objects do not touch the edges of the package.

Long objects (rugs and carpets, textiles, tubes)

  • Tubes: Pack these so that they do not cause damage to other items or the transport fleet.

  • Rugs and carpets, textiles: Protect these with bubble wrap, for instance, in addition to other packaging material.

Note the maximum dimensions of parcels
