Shipping Knitwear Samples by Courier: Why Parcels Get Stuck and How to Stop It

By YZR Sweaters · 2026-10

It is the least glamorous part of a knitwear programme and it costs more schedule time than most sampling problems. A first sample sitting in a customs shed for nine days is nine days off the development calendar, and it usually has nothing to do with the sweater. Here is what actually causes it, and what we ask buyers to settle with us before anything is collected.

Declared value: honest beats clever

Two errors, opposite in direction, and both common.

Declaring almost nothing. Writing a token value — or "no commercial value" — on a parcel of finished garments invites customs to treat the declaration as unreliable and value the goods themselves. Once that happens the release is out of your hands, because the officer is now working from their own assessment rather than your paperwork. A parcel of ten knitted samples is commercially worth something, even if it is not being sold; ten is enough to resell, and customs officers know it.

Declaring the bulk unit price. The opposite error is putting the full retail value on samples, which attracts duty and tax on money that was never going to change hands. The honest middle is what you want: declare a realistic commercial value for the goods being sent, described accurately as what they are.

Our notes on HS codes and duties explain how classification drives what is owed. The point for samples is that the value should be defensible if someone opens the box and looks at it.

The invoice line that prevents most problems

A courier's paperwork is not just an address label; the commercial invoice is what customs reads. Ask for these five things on it, every time:

• A clear purpose statement — "knitwear development samples, not for resale" is far more useful than "gift" or "documents".
• Quantity in pieces, with a description per style. Twenty pieces across five styles should read as twenty pieces across five styles, not as "clothing".
• Fibre composition and HS classification per style, taken from real information rather than guessed. Our notes on shipping documents cover how this lines up with the bulk paperwork later.
• Realistic unit and total values, in a named currency.
• Country of origin.

If the parcel contains anything a customer cannot buy — a half-made sleeve, a swatch card, a returned sample being reworked — say so plainly. Unusual contents get opened, and an opened parcel that matches its paperwork is released quickly.

Who pays the duty — decide before collection

This one produces more bad feeling than anything else in shipping, because the cost is small and the argument is not.

Duty and import tax on a commercial parcel normally have to be paid by somebody before release. If nobody has arranged it, the courier pays it on the recipient's behalf and then chases the recipient with an administration fee on top — which arrives as an unexpected invoice rather than as a shipping cost the buyer budgeted. There are three working arrangements:

• Bill to shipper. The supplier's account pays everything, including duties. Cleanest for the buyer, and normal practice where a factory is actively developing a programme.
• Bill to receiver. Charges go to the buyer's own courier account. Fine where the buyer has one and wants visibility.
• Third-party billing. A forwarder's account, used when neither side wants the cost on their own account.

The commercial question underneath this is the same one our notes on Incoterms address for bulk: whoever is named should know they are named. A surprise duty bill is rarely about the money; it is about finding out afterwards.

Courier or freight — and the in-between

Samples usually go by courier because they are small and urgent. Bulk economies are covered in our notes on air versus sea freight, but the sample decision has a different shape:

• One or two samples: express courier, booked directly, tracking watched daily.
• A full salesmen-sample set for a show: worth comparing consolidated air freight against several express parcels. One consolidated shipment can be cheaper and easier than eight parcels, though it moves slower.
• Samples you will bring back: check whether an ATA Carnet or a temporary-import arrangement suits you. A carnet lets professional samples cross borders without paying duty each time, which matters enormously if the set travels to three shows in a season — our notes on trade shows cover where this arises.
• Samples returned for correction: the same discipline applies in reverse. Returning goods described as commercial imports is how a buyer pays duty on their own alterations.

Timing: the delays nobody budgets for

Transit time is published and reliable. Clearance time is neither, which is why it is the part that breaks schedules.

• Public holidays at either end — Chinese New Year and Golden Week on one side, local holidays on the other. Both ends matter.
• Weekend arrival. A parcel landing on a Friday evening can lose a full working day to a delivery attempt nobody received.
• Customs queries answered slowly. When customs asks a question, the clock stops until someone answers. Give the customs contact your phone number and check your email during the transit window. Our notes on the buying calendar cover the seasonal peaks when everything slows together.
• Incorrect recipient details — an incomplete tax ID or a contact who has left the company accounts for a surprising share of held parcels.

The practical mitigation is unglamorous: send early in the week, send before a known holiday, and answer within hours if customs writes.

Arrival stage

Once delivered, photographs of how it arrived are worth having before anything else happens. Garments creased, wet or crushed in transit are a shipping problem rather than a making problem, and the claim window closes quickly. Our notes on reviewing samples cover evaluating the sample itself — this note only concerns getting it through the door.

At YZR Sweaters we work with partner factories holding BSCI, SEDEX and Oeko-Tex certifications, welcome factory audits, and support third-party inspection through firms such as SGS and BV. On samples we book the courier against our own account unless you would rather we used yours, we write the invoice the way customs can read it rather than the way it is quickest to type, and we send you the tracking number the same day it is collected.
