Many people who emigrate or settle overseas want to bring their fridge, washing machine, and TV from back home. Shipping appliances by sea is nothing like sending luggage: if the volume falls short of the minimum, if the packaging isn't up to standard and gets damaged, if customs holds it up and demands extra duty or sends it back, any one of those can turn into a mess.

Seapoe Relo handles more than 8,000 international ocean shipping orders a year, and appliances are one of the most common categories people ship. Whether an appliance can be shipped, how to pack it, and how to clear customs are the three thresholds for appliance shipping. Here's each one.

1. Which appliances can go by sea and which can't

Don't rush to pack. Check the list first. Appliances with a built-in battery can't go by sea, and that's a hard rule.

Why can't appliances with batteries go by sea? International shipping classifies lithium batteries as Class 9 dangerous goods, the same category as standalone batteries and lighters. There are only two ways to take them: pull the battery and ship the unit by sea, or ask the airline about carrying it with you. Some battery-powered speakers and desktop computers fall into an assessable category, and can only ship if a consultant approves them.

2. Shipping starts at 2-3m³. What if one appliance isn't enough?

International moving is billed by cubic meter (m³), not by the piece or by weight. Most routes typically start at 2-3m³, and you pay the minimum even if you're under it.

The volumes make it obvious:

Even the biggest item, a double-door fridge, can't hit the minimum on its own. Billed at the minimum, you're paying for space you don't use.

2.1 What people actually do: mix appliances with furniture

When you move, pack appliances together with furniture and ship the whole batch once it reaches the minimum. A TV, a sofa, a bed frame, and a few boxes of household goods easily add up to 3-5m³, and the appliances ride along.

This is also why international moving naturally suits mixed "appliances + furniture" shipping: a single appliance rarely ships by sea on its own, but mixed in with furniture the cost spreads out and works out well.

2.2 An easy-to-miss variable: packaging inflates volume by about 20%

Once items are packed, volume usually runs about 20% above the net volume. That's the common reason "I estimated 5m³ before the move and it measured 6m³," and it's not a measuring error. Appliances get even bulkier in wooden crates: crate wall thickness, forklift feet, and internal cushioning all take up space, so leave some margin when you estimate.

3. Appliances are fragile, so a fumigation-free wooden crate is a must

The biggest risk in appliance shipping is impact. Ocean shipping goes through container loading, crane lifting, the ship rocking, port discharge, and inland transfer. Appliances in cardboard boxes take far more of a beating than you'd imagine. So for appliances going abroad, a fumigation-free wooden crate is basically standard.

3.1 What is a fumigation-free wooden crate?

It's made from plywood or three-ply board, not solid wood. The International Plant Protection Convention (ISPM 15) requires solid wood packaging to be fumigated before export, which takes time and costs extra, usually a few hundred yuan per shipment. Fumigation-free plywood skips that step, so the timeline isn't affected and the cost doesn't go up.

3.2 Wooden crate pricing

Custom crates are billed by cubic meter (anything under 1m³ counts as 1m³), usually a few hundred yuan per cubic meter; unpacking the crate at the destination runs a few hundred yuan per piece. That's not cheap, but compare it to a smashed TV and it's clear which is the bigger loss.

4. Appliance customs clearance has its own rules. Don't let one appliance get stuck at customs

Clearing appliances is different from clearing ordinary furniture, and there are three pitfalls to avoid.

4.1 Appliance brands can trigger an infringement inspection

Appliance boxes usually carry the brand name and a manual. Some brands have registered their trademarks with customs, so packaging with the brand logo can trigger an infringement inspection and the goods get held. Saudi Arabia and Middle East routes are especially strict: branded appliances can't ship because the packaging carries a logo.

Before shipping, confirm with your consultant whether your appliance brand can be shipped.

4.2 Clearance policy for appliances varies a lot by country

The same appliance shipped to different countries can follow completely different clearance paths and tax rules. Figure out the destination policy before you leave, or you risk paying extra duty at the port or even having the goods returned, which costs far more than the freight. An appliance shipped on its own carries a higher inspection risk; mixed in with furniture, that risk drops a lot.

5. Shipping appliances overseas: a pre-departure checklist

Once you've got the three thresholds above straight, run through this checklist before you start:

1. List every item

Write out each appliance you plan to ship: brand, model, dimensions, weight, whether it has a battery or refrigerant. Send it to the moving company's sales rep and have them estimate volume and cost item by item. That gets you closer to the final price than measuring after packing.

2. Filter out what can't ship

Check the can/can't table in section 1 and pull out anything with a built-in battery first. Those can't go by sea, so make other arrangements early (remove the battery or carry it with you). If you have fragile appliances, remember to budget for wooden crates. For appliances that are too small on their own, decide which furniture to pack them with to reach the minimum.

3. Handle packaging and labels

• Check with the moving company ahead of time on whether they can pack and reinforce, and ask for examples of past appliance packing jobs
• Remove brand labels, manuals, and logos
• Confirm the moving company can provide custom fumigation-free wooden crates

4. Confirm destination policy

Use the clearance table in section 4 to confirm the destination country's special requirements for appliance imports (brand restrictions, tax rates, duty-free conditions) so nothing goes wrong at the port. If you're unsure, contact a consultant for an assessment.

5. Nail down the quote details

Before signing, confirm: does the quote spell out what's included and excluded? Is the crate fee listed separately? Are the conditions that trigger surcharges written into the quote up front? Can measurement come with photos and the calculation?

6. For shipping appliances overseas, a professional international mover saves you trouble

Appliance shipping involves far more steps than sending a parcel, and the minimum volume, packaging, and clearance issues above can each turn into a headache.

A professional international mover and a commercial consolidation company are two different services, so comparing them on price alone means nothing:

For something fragile like an appliance, every step from packing and crate building to customs declaration needs professional handling. A consolidation company doesn't handle packing or clearance, so if something goes wrong, you're on your own.

For a professional international mover, Seapoe Relo（熙浦国际搬家） is worth a look: founded in 2015, 8,000+ orders in the past 12 months, 100+ people each in its office and logistics teams, its own warehouses and logistics team, and a service network covering nearly 100 countries and regions worldwide.

Seapoe Relo has plenty of hands-on experience shipping appliances by sea:

If you're not sure how many cubic meters your appliances and other items come to, send photos or a list to Seapoe, and they'll estimate the volume and cost item by item so you can decide the cheapest way to ship.
