TL;DR: For UK→US parcels, both platforms resell UPS Worldwide Economy DDP. TradeWind's flat £1 PAYG markup and US-specific duty engine typically come out £2–£4 cheaper per parcel. Pricing is line-itemised — base rate, fuel, and pre-paid US duty shown separately — and a live Royal Mail PDDP comparison appears on every quote.
What Intership is genuinely good at
Intership is a smaller, less brand-recognisable UK shipping platform than Parcel2Go or Parcelmonkey, but they're a real business with a real product and a few legitimate strengths:
- Aggressive international rates on some lanes. Intership trims margins to win on price, particularly on Asian and European international parcels where they have decent broker agreements.
- Simple, no-frills booking flow. No cross-sells, no aggressive PrePay upsell, no third-party offers at checkout. The interface is functional and gets out of the way.
- Multi-carrier coverage on the international side. UPS, DHL, FedEx, and a couple of consolidators are typically on offer for international lanes.
- Reasonable customs paperwork generation. Commercial invoice and customs declaration generation is competent, if not class-leading.
- UK origin. Pricing is in GBP, support is UK business hours, customs paperwork is set up for UK exporters.
For sellers who already use Intership for European or Asian parcels and value consistency across lanes, sticking with one platform is reasonable. For UK→US specifically, the case is weaker.
Where TradeWind beats them on UK→US specifically
TradeWind is not trying to be a general-purpose international reseller. The entire product is built around one shipping lane after the end of US de minimis. That focus produces specific advantages:
- Cheaper price on the same UPS service. For a typical 1–2kg parcel, our UPS Worldwide Economy DDP price is £2–£4 lower than Intership's for the same physical service.
- Flat £1 PAYG markup. Our markup over carrier rate is a flat £1 per label. Intership applies a percentage markup over the wholesale rate (typically 6–12%, though not transparently published) which compounds on heavier or more valuable parcels.
- US-specific duty calculation. Our HS-code lookup queries the USITC HTS rate tables directly, with the post-EO-14324 reciprocal-tariff floor handled automatically. Intership's duty calculation is general-purpose international.
- Line-itemised pricing. Base rate, fuel surcharge, and pre-paid US duty shown as separate, labelled lines. The HS code and the tariff rate used are visible on the quote.
- Live "vs Royal Mail PDDP" comparison. Every TradeWind quote shows the apples-to-apples Royal Mail International PDDP equivalent next to our UPS price. Intership doesn't do this.
- Built for the post-de-minimis lane. The product was designed after Executive Order 14324. It assumes ad valorem duty on every parcel and is laid out around that.
- Guest checkout. No account required to book a label. Pay with card, Apple Pay, or Google Pay and print straight away.
- Shopify integration. Live for UK sellers shipping to the US. Etsy and WooCommerce on the roadmap.
Worked example: 1.5kg parcel, London to Los Angeles
Same parcel, same carrier service, two platforms. Sender SW1A 1AA, recipient 90001 Los Angeles, declared value £40, HS code 6110.20 (cotton jumper).
| Base rate (incl. fuel) | £17.75 |
| Pre-paid US duty | £5.00 |
| Total | £22.75 |
| Base rate | £13.50 |
| PAYG markup | £1.00 |
| Pre-paid US duty | £5.00 |
| Total | £19.50 |
Saving: £3.25 per parcel, roughly 14%. For a seller shipping 50 parcels a month to the US, that's ~£162 a month back in margin. Indicative figures for May 2026; live quotes will vary slightly with weight, dimensions, and current fuel surcharge.
Scenario: 2kg parcel, declared value £120, UK to New York, 5–7 day delivery
Both platforms reselling UPS Worldwide Economy DDP, same physical service, different markup models.
| What you pay | Intership | TradeWind |
|---|---|---|
| Carrier rate | ~£18–22 | £15.20 |
| Fuel surcharge | bundled in rate | included |
| Customs admin fee | embedded in markup | £0 |
| US import duty (pre-paid) | £8–12 | £8–12 (shown separately) |
| Total cost to you | ~£26–34 | ~£24–28 |
| Total cost to buyer | £0 (DDP) | £0 (DDP) |
Bottom line
Intership is a competent multi-lane reseller with a no-frills interface, but their general-purpose duty engine and bundled pricing lack the transparency and US-specific accuracy that post-de-minimis shipping requires. TradeWind's USITC-linked tariff calculation, line-itemised quotes, and flat £1 markup mean you always know exactly what you're paying and why — and for UK→US specifically, that combination consistently comes out cheaper than a percentage-markup generalist.
When Intership is the right choice
To be fair about it, Intership is a reasonable choice when:
- You ship to many international destinations. If most of your parcels are going to Europe or Asia and only a handful to the US, having one platform across all lanes has real workflow value.
- You already have an Intership account with workflow set up. Saved addresses, billing history, and integrations are switching costs we don't pretend don't exist.
- You want a no-frills, plain interface. Intership is functional and gets out of the way. So is TradeWind, but if you're used to one, the other isn't obviously different.
- You ship larger or unusual consignments. TradeWind's scope is parcels up to about 30kg on UPS Worldwide Economy DDP; Intership supports a wider range of services for pallets, oversized, and freight-style consignments.
When TradeWind is the right choice
- UK→US is most or all of your shipping volume. One lane, optimised pricing, US-specific duty engine.
- You want clean, transparent pricing. Base, fuel, duty as separate lines. The HS code and tariff rate appear on the quote.
- You want the lowest UPS Worldwide Economy DDP price specifically. Same service, lower markup.
- You're post-de-minimis aware. You know about EO 14324, you know DDU is broken for the US, and you want a platform that defaults to DDP without having to be told.
- You're a Shopify seller shipping to the US. Native integration is live.
- You want guest checkout. No account required. Pay-as-you-go from the first label.
Pricing transparency at a glance
- PAYG: £1 flat per label
- Monthly fee: £0
- Volume tier: lower markup at 100+ labels/month
- Duty admin fee: none

One caveat: Intership does not publish its exact percentage markup, so the 6–12% figure here is derived from comparing displayed UPS WWE DDP prices against published UPS UK reseller carrier rates on a sample of weights and origin-destination pairs in April–May 2026. The figure may move; verify with a live quote on both platforms before deciding. Also confirm the variant is DDP, not DDU, before booking.

Is TradeWind cheaper than Intership for UK to US shipping?
On the same UPS Worldwide Economy DDP service, TradeWind is typically £2–£4 cheaper per parcel on a 1–2kg shipment. Intership trims margins on some international lanes, but for UK→US our flat £1 PAYG markup with no admin charge tends to come out lower once duty pre-payment is included.
What is the difference between TradeWind and Intership?
Intership is a general-purpose UK international shipping reseller covering many lanes. TradeWind is a UK→US specialist built around UPS Worldwide Economy DDP after the end of US de minimis. Intership covers more lanes; TradeWind goes deeper on this single lane with HS-code lookup and USITC tariff calculation.
Do I need an account to use TradeWind?
No. Guest checkout is supported — pay with card, Apple Pay, or Google Pay and print your label without signing up. An account unlocks address book, label history, store integrations, and the volume tier.
Does Intership pre-pay US import duty?
On their DDP variants, yes. Verify the service is the DDP version, not DDU, before booking — under the post-de-minimis regime, DDU parcels to the US increasingly come back refused. TradeWind only sells DDP.
Why is TradeWind specialised on UK to US shipping?
Executive Order 14324 (29 August 2025) ended the $800 de minimis exemption. From 28 February 2026, every parcel into the US clears with full ad valorem duty. That single rule change made UK→US a lane where a focused product can deliver better duty calculation, cleaner customs paperwork, and tighter pricing than a multi-lane reseller.
