Choosing a Shipping Line: Express vs Postal vs Sea, and General vs Sensitive

9 min read· intermediate· Updated Jul 9, 2026

The shipping line you pick decides how fast your haul arrives, how much you pay, and sometimes whether it is allowed to leave China at all. Two separate choices are hiding inside that one decision, and getting either wrong is one of the most common beginner mistakes.

Two Choices, Not One

When you reach the shipout step and your agent shows you a long list of lines, it looks like a single menu. It is really two independent questions stacked on top of each other, and you answer both at once.

The first question is the speed tier: how fast, and how much per kilogram. Your options run roughly from economy or sea freight (slowest, cheapest per kg), through standard postal (mid), to express (fastest, priciest).

The second question is the channel type: general versus sensitive. A general line carries ordinary goods. A sensitive line is a special channel required for anything with a battery, magnet, liquid, powder, food, or a brand name on it.

These two axes are independent. A line can be fast and general, slow and sensitive, or any other mix. If any item in your box is sensitive, you are forced onto a sensitive line no matter which speed tier you wanted, and that narrows your choices.

So before you compare prices, sort your haul: is everything ordinary, or is even one thing sensitive? That answer shapes the whole list you get to pick from.

One menu, two questions: how fast you want it, and whether anything is sensitive.

The Three Speed Tiers

Every line falls into one of three broad speed bands. The numbers below are rough, as of 2026, and shift with fuel prices and your destination, so treat them as ballpark, not quotes. Always pull live prices for your own country and weight before you decide.

TierExample linesRough timeRough costBest for
ExpressDHL, FedEx, UPS, SF3-10 daysAround $30-60 for 2kgSmall, urgent, high-value hauls where speed beats price
Standard / postalEMS, EUB / ePacketRoughly 10-35 daysEMS around $20-35 per 2kg; EUB economy around $10-20 per 2kgThe middle ground: reasonable price, reasonable wait
Economy / seaSea freight and budget lines30-60 daysAround $8-15 per kgHeavy hauls where you can wait and want the lowest per-kg rate
Rough bands as of 2026. Actual prices vary by destination, weight, and current fuel surcharges.

The pattern is simple: the faster you want it, the more you pay, and the more a bulky-but-light box hurts you. Express lines are worth it when an item is small, valuable, or time-sensitive. Economy and sea shine when your box is heavy and you are patient, while standard postal is a sensible default for most first orders.

One thing to watch: express lines usually divide volumetric weight by a harsher number, so a big light box gets penalised most there. That interaction is covered in the shipping guide on weight, and it is a real reason not to auto-pick express for pillows or padded jackets.

General vs Sensitive: What Counts and Why It Matters

This is the axis beginners forget, and forgetting it can get your whole shipment rejected at the last moment. Chinese export customs and the carriers class goods as Normal, Sensitive, or Prohibited.

Prohibited items no line will carry. Sensitive items can ship, but only on a dedicated sensitive-goods line, which costs more and reaches fewer countries.

An item is sensitive if it has any of these traits:

  • A battery of any kind: power banks, watches, toys, headphones, and most electronics.
  • A magnet: many speakers, earphones, and magnetic accessories.
  • Liquid: perfume, cosmetics, drinks, oils, and anything that can spill.
  • Powder or food of any type.
  • A brand name printed or labelled on it, which many lines treat as sensitive regardless of what the item is.
One sensitive item locks the whole box

If you put a battery, magnet, liquid, or branded item on a general line, the shipout can be refused at export customs, and the parcel risks being returned, fined, or confiscated. A single power bank forces the entire consolidated box onto a sensitive line. Flag anything sensitive to your agent early, and check that a sensitive line even reaches your country before you build the haul.

The practical lesson: decide the general-versus-sensitive question first, because it filters everything else. Sensitive lines are decided at shipout, tend to be pricier, and serve a shorter list of destinations.

If your haul mixes a sensitive item you do not urgently need with ordinary goods, sometimes the cheapest overall move is two boxes, one general and one sensitive, rather than dragging everything onto the pricier channel.

A single power bank can force your entire box onto a pricier sensitive line.

Per-Country Reality: Whitelists, Floors, and Caps

A shipping line is a specific carrier on a specific lane, and each one has its own rules about where it goes and what weights it accepts. Do not assume a line that works for a friend in the US will work for you.

  • Destination whitelist: each line serves only a set list of countries. A line valid for the US may be unavailable, slower, or pricier to the EU, UK, or Australia.
  • Minimum weight floor: some sensitive or heavy lines will not accept a parcel under a certain weight, so a tiny order may not qualify.
  • Maximum weight cap: lines also have an upper limit, and a very large haul can blow past it, forcing you to split into two boxes.

Check compatibility with your own country before you start adding items to your cart, not after. Building a perfect haul and then discovering no line serves your address at that weight is a frustrating, avoidable dead end.

Shopwaver's shipping comparison lets you set your destination country and weight first, so you only ever see lines that can actually deliver to you.

DDP vs DDU: Who Pays the Import Tax

Import tax is separate from shipping, but the line you pick often bundles a choice about who pays it and when. Those two options are DDP and DDU.

OptionWhat it meansUp-front priceAt the door
DDP (Delivered Duty Paid)Tax and clearance are prepaid inside the shipping price for an extra feeHigherNo surprise bill; the courier just delivers
DDU (Delivered Duty Unpaid)Tax is not prepaidLowerThe courier bills you for duty, VAT or GST, plus a handling fee before releasing the parcel
DDP trades a higher up-front price for no doorstep surprise. DDU is cheaper up front but the bill can arrive later.
Duty-free thresholds are mostly gone, as of 2026

The old US $800 de-minimis threshold that let small parcels enter duty-free ended for China on May 2, 2025, ended for all other countries on Aug 29, 2025, and was indefinitely suspended around June 2026. In plain terms, nearly every parcel can now face duty. That makes DDP and an honest declared value matter more than the old habit of keeping hauls small. Rules change fast and differ by country, so check your own country's current threshold before you order.

A Simple Way to Decide

Walk your haul through these steps in order and the right line usually names itself.

  1. 1
    Check for sensitive items first

    If anything has a battery, magnet, liquid, powder, food, or a brand name, you need a sensitive line. Confirm one exists for your country before going further.

  2. 2
    Set your destination and weight

    Filter to lines that actually serve your country and accept your parcel's weight, respecting both the minimum floor and the maximum cap.

  3. 3
    Decide how fast you truly need it

    Urgent or high-value and light goes express. No rush and heavy goes economy or sea. Most first orders sit comfortably on standard postal.

  4. 4
    Compare on real numbers, not per-kg alone

    Look at the full quote for your actual weight and box size, including the volumetric divisor, not just the headline rate per kilogram.

  5. 5
    Choose DDP or DDU

    Pick DDP if you would rather pay a bit more now and get no surprise bill, or DDU if you are comfortable paying the courier on delivery.

Insurance and Declared Value

Insurance is optional and usually costs roughly 3 percent of the value you declare. Some agents include basic coverage free, often up to around $100, so check what you already have before buying more.

For a cheap haul you may skip it; for anything you would be genuinely upset to lose, it is a small price for peace of mind.

Declared value is the figure written on the customs form, and it does double duty. It drives how much duty or VAT you might be charged, and it caps what insurance will pay out if the parcel is lost.

That pulls in two directions. Declaring too high inflates your duty bill, while declaring too low can void your insurance and invite extra scrutiny at customs.

The honest, sensible move is to declare roughly what the goods are worth. Remember that most customs holds are routine inspection that clear in a few days with no action, so trying to game the value rarely pays off and can cause the very delay you were trying to dodge.

Can I put my headphones and my clothes in the same box?

Only on a sensitive line. Headphones usually contain a battery or magnet, which makes the whole box sensitive. If you want to keep the clothes on a cheaper general line, ship them separately.

Why is my light, bulky box so expensive to ship?

You pay on chargeable weight, which is the greater of actual weight and volumetric weight. Bulky-but-light items like boxed shoes or jackets get billed on their size. Repacking to remove boxes and picking a line with a friendlier divisor both help.

Is express always the fastest and best?

It is the fastest, but not always the smartest. Express lines cost the most and penalise bulky boxes hardest. For a heavy, non-urgent haul, economy or sea can save a lot if you can wait.

Will I get taxed now that de-minimis is gone?

As of 2026, most parcels can face duty because the old duty-free thresholds have been removed or suspended. Rules differ by country, so check your own current threshold, and consider a DDP line so the tax is prepaid with no surprise bill.

How do I know a line even ships to my country?

Each line has its own list of served countries plus a minimum and maximum weight it accepts. Set your destination and weight first and only compare lines that qualify, rather than picking a line and hoping.
