October is the last month to fix the economics of Black Friday returns

For UK retailers selling into the EU, October is no longer simply the month before Black Friday. It is the final full month to test whether promotional pricing, customs data and returns infrastructure still work under the rules introduced this year, says Paweł Zakielarz, CEO of ShopReturns.

The €3 customs charge has already changed the economics of low-value ecommerce shipments, Product Identifiers become mandatory on the 1st of November, and the orders placed during peak will begin returning after Christmas. Retailers that look only at November sales risk discovering the real margin on those orders in January.

Black Friday falls on the 27th of November this year. By then, the €3 customs charge on low-value ecommerce imports will have been in place for almost five months. The peak season therefore will not test whether retailers know that the rules have changed.

It will test whether they have translated those changes into pricing, product data and operational decisions. October matters because several variables that are manageable at normal volumes become harder to correct once peak begins. Promotional pricing can move baskets across customs thresholds.

Gift purchases increase the number of product categories in a single order. Product Identifiers become mandatory on 1 November. And after Christmas, a proportion of those November orders will start travelling in the opposite direction.

According to Paweł Zakielarz, CEO of ShopReturns, a company specialising in cross-border returns and helping online retailers manage returns locally across European markets, this is where retailers need to look beyond the headline cost of sending a parcel into Europe. The mistake is to calculate Black Friday profitability at checkout.

For a cross-border retailer, the transaction is not economically finished when the parcel reaches the customer. Some of those products will come back in December and January, and the cost of getting them back, checking them and putting them into saleable stock again is part of the margin on the original order.

October is the last comfortable moment to model that before volumes rise. – Paweł Zakielarz, CEO, ShopReturns Four things are different this year Every B2C distance-sales parcel cleared under IOSS carries €3 per tariff line. Not per parcel.

Goods sharing tariff classification, description and country of origin sit on one declaration line and carry one €3 charge, however many units. Different categories create separate lines. A three-category parcel costs €9.

B2B consignments to a VAT-registered recipient stay on standard duty rates, and non-IOSS commercial shipments are declared differently – which regime you’re in depends on your clearance route, not just what’s in the box. Product Identifiers become mandatory on 1 November. Voluntary since the 1st of July with no penalties in the window.

From November they’re required on distance sales declarations: a standardised identifier such as an EAN where one exists, a non-standardised one where it doesn’t, and a merchant identifier. A handling fee of around €2 is expected at the same time, taking the combined charge to roughly €5. Final amount and basis still being confirmed in Brussels.

Returns changed, permanently. When goods come back after release, you can no longer ask customs to invalidate the import declaration because the customer changed their mind. The €3 stays paid. None of these are peak-season problems in isolation. Together, in November, they are.

Why peak makes each one worse Discounting pushes baskets under €150 and into the flat-rate regime. A basket sitting above the threshold at full price falls under it at 40% off, moving from normal tariff rules into the €3-per-line world. For genuinely UK-origin goods qualifying under the UK-EU Trade and Cooperation Agreement, above €150 can mean 0% duty.

Discount it below and you pay per line instead. One caveat that decides this: preference and the flat rate are mutually exclusive. If VAT is collected through IOSS, the €3 applies regardless of origin. Preference survives only outside IOSS, on a standard H1 declaration with proof of origin.

Some of your promotional pricing will cross that boundary without anyone deciding to. Peak baskets are mixed baskets. People who buy one item in March buy four in November, across four categories, because they’re buying gifts. Your average tariff lines per order rises exactly when your volume does. Run at 1. 6 lines in a normal month and 2.

8 in peak, and your duty per order goes from €4. 80 to €8. 40 on the busiest orders of the year. Gift sets are the worst-case product and your best seller in November. A four-component set is potentially four lines and €12.

Genuine retail sets can sometimes classify under a single heading, which is a question for a customs specialist now rather than in December. Doorstep charges do the most damage in gifting season. A parcel held for a customs payment in mid-November isn’t a delayed order, it’s a missed occasion and a refu
