Most international parcels that get held, delayed or rejected have the same three problems: a vague item declaration, weak packaging, or missing documents. All three can be fixed before the parcel leaves your hands.

International shipments go through more checks than domestic ones. The courier inspects the parcel, and customs at both ends needs to know exactly what is inside. When the details are unclear, the parcel stops moving until someone sorts it out.

This guide covers the three best practices every ParcelDaily sender should follow before handing over an international shipment, plus answers to the questions we hear most often.

1. Declare your items accurately

Every declaration should state three things clearly: the brand name, the product description and the quantity.

A generic description such as “Contact Lens” does not tell the courier or customs what the item really is. A specific one does.

Declaration
IncorrectContact Lens
CorrectAcuvue Oasys 1-Day Contact Lenses, 2 boxes (30 pieces each)

A simple way to check your declaration: could someone who has never seen your parcel know exactly what is inside, and how many, just by reading it? If not, add more detail.

2. Pack your parcel properly

Use a courier flyer whenever possible. Flyers are the preferred packaging for international shipments.

If your item needs a box, make sure the box is securely wrapped with transparent plastic. The wrap holds the box together during the longer journey, and the transparent material keeps the box and its labels visible for inspection.

International parcels are handled many more times than domestic ones, so packaging that is fine for a local delivery may not survive an overseas trip.

3. Attach supporting documents

For supplements and liquid products, attach the relevant documents to the parcel so the courier can inspect them:

  • MSDS (Material Safety Data Sheet), which lists what the product contains and confirms it is safe to transport
  • Invoice, which shows what the item is, the quantity and its value
  • Other supporting documents related to the product

Attach the documents to the parcel itself. If the courier cannot find them during inspection, the parcel may be treated as if it has no documents at all.

What happens if you skip these steps

Generic or inaccurate declarations and improper packaging can cause your shipment to be:

  • Held for further checks
  • Delayed on the way to your customer
  • Rejected by the courier
  • Confiscated

Serious non-compliance may also lead to account suspension and penalties. Any penalties are borne by the sender.

Quick checklist before handover

Run through this list before you hand your international parcel to the courier:

  1. The declaration states the brand name, product description and quantity.
  2. The item is packed in a courier flyer, or in a box securely wrapped with transparent plastic.
  3. For supplements and liquids, the MSDS, invoice or supporting documents are attached to the parcel.
  4. The declaration matches what is actually inside the parcel.

Ship overseas with confidence

A clear declaration, proper packaging and the right documents take a few extra minutes, and they keep your parcel moving all the way to your customer.

Frequently Asked Questions

Couriers and customs need to know exactly what is in the parcel to clear it. A detailed declaration lets them process your shipment without stopping it for extra checks.

Any description that names only a product category, such as “Contact Lens”, “Supplement”, “Cosmetics” or “Clothes”. A proper declaration adds the brand, the specific product and the quantity, for example “Acuvue Oasys 1-Day Contact Lenses, 2 boxes (30 pieces each)”.

Yes. Courier flyers are preferred, but if you use a box, it must be securely wrapped with transparent plastic before handover.

MSDS stands for Material Safety Data Sheet. It describes what a product is made of and how to handle it safely. You can usually request it from the product’s manufacturer or supplier.

Supplements and liquid products. Attach the relevant MSDS, invoice or supporting documents to the parcel so the courier can inspect them.

Your shipment may be held, delayed, rejected or confiscated. Getting the declaration and packaging right before handover is the best way to avoid this.

Penalties are borne by the sender. Serious non-compliance may also lead to account suspension.

Contact the ParcelDaily support team before you hand over the parcel. It is much easier to fix a declaration or packaging issue before shipping than after the parcel is held.
