Sending stuff internationally? The right envelope can save you from a bunch of headaches and make sure your items land safely and affordably. Here’s a quick breakdown of the best envelopes (and types of packaging ((e.g, flat mailers, padded mailers that may be considered as envelopes)) for international mailing, along with some tips on common pitfalls, tracking, insurance, and dealing with country-specific rules.
3 types of envelopes for international mail
- C4 Envelopes: These are large envelopes measuring 229 x 324 mm, suitable for sending A4 documents without folding.
- C5 Envelopes: These envelopes are 162 x 229 mm, ideal for sending A4 documents folded in half.
- DL Envelopes: Measuring 110 x 220 mm, these envelopes are perfect for sending A4 documents folded into thirds widthwise.
Types of packaging that be considered as envelopes for international mail
- Standard paper envelopes: Ideal for sending letters and documents. They come in various sizes, such as DL, C5, and C4.
- Cardboard envelopes: These are sturdier and provide more protection, making them suitable for sending items like books, CDs, or important documents.
- Mailer bags: Made from different types of materials (plastic or sustainable options), these are lightweight and water-resistant, perfect for sending clothing or other non-fragile items.
Your do's and don'ts for sending envelopes internationally
Underestimating shipping costs
No one likes overspending on shipping. Do your homework. Check out all potential costs upfront, including customs duties and taxes.
Using inadequate packaging
Pick the right type of envelope and don’t skimp on padding if needed.
Incomplete and incorrect custom forms
Missing info can get your package stuck or sent back. Double-check all the details and describe the contents clearly.
Ignoring size and weight restrictions
Overlooking these can lead to rejection or extra fees. Always measure and weigh your package before sending it off.
Tracking and insurance for international shipment
Major carriers offer tracking, which lets you (and your customer!) keep an eye on the journey. Tracking also gives peace of mind and helps manage customer expectations.
Insurance would always be best for expensive or irreplaceable items. Get it through your carrier or a third-party insurer. But this can be a little costly, so make sure to balance the cost of insurance against the item’s value.
Some places have bans on certain materials, special labeling rules, or limits on package sizes and weights.
