Seamless Sets Wholesale Supplier UK: Demand Signals & Import Notes

# Seamless Sets Wholesale Supplier in UK: What Buyers Need to Know About Demand, Duties, and Delivery You’ve just found a UK retailer that wants 500 seamless sets — but you’re not sure whether the landed cost after UK customs will leave you any margin, or whether your standard size chart will fit their members. That’s the kind of operational question we answer every week at Alpinario. As a 20+ year Zhejiang factory (not a trading company), we’ve been feeding the UK market with seamless sets for years, and we’ve learned the signals, the numbers, and the shortcuts that make or break a B2B deal. This article walks you through the concrete details you need to import seamless sets from China to the UK, with prices, duties, sizing, and timelines that actually match reality. --- ## Market demand signals UK buyers are voting with their orders. Over the past 18 months, seamless sets — sports bras and leggings or shorts in one coordinated look — have become a staple for boutique gyms, independent yoga studios, and Amazon sellers in the UK. We see it in our own order book: UK inquiries now represent roughly 30% of our seamless set production, up from 10% three years ago. The top sellers are high-waisted leggings with a compression fit, paired with a medium-support bra that has a racerback or scoop-neck design. Here are the specific demand signals we track from our UK clients: - **Fabric preference**: 260–280 GSM nylon/spandex blends (4-way stretch, matte finish) outsell polyester by 3:1. - **Colour palette**: Black, navy, heather grey, and olive green account for 70% of reorders. - **Features that sell**: Phone pockets (side seam, large enough for iPhone Pro Max), wide waistbands (9–10 inches), and squat-proof opacity. - **Fit expectation**: UK buyers prefer a true compression fit for leggings and a snug, but not tight, band for bras. One consistent signal is the demand for small-batch, custom-labelled sets. UK gyms and Amazon sellers rarely want to commit to 1,000 pieces upfront. They test with 300–500 pieces, then reorder in 1,000s once they prove the style. That’s exactly why our [wholesale sportswear](/wholesale-sportswear) model with a 1-piece MOQ (yes, one piece) works for them — they can sample first, then scale without blowing their budget. --- ## Import duties & shipping UK import duties for seamless sets depend on the HS code. Most seamless sportswear falls under **HS 6110** (knitted pullovers, cardigans, etc.) or **HS 6114** (other knitted garments). Based on current UK Global Tariff rates, the duty is typically **12%** for garments made of synthetic fibres, although some blended fabrics may qualify for 8% if the cotton content is high. You’ll also pay **20% VAT** on the total landed value (goods + freight + duty). Don’t forget to check the **Trade Preference Scheme** — if your goods meet the UK’s rules of origin for developing countries, you might get a reduced rate. (China is not a beneficiary, so plan for the full 12%.) **Shipping steps from our factory to your UK door:** 1. **Production**: after sample approval, we run your order. 2. **Quality check**: our QC team inspects every piece for seams, colour, and sizing. 3. **Packing**: we fold, polybag, and label per your instructions — including FBA barcodes if you’re sending to Amazon UK. 4. **Documentation**: we provide a commercial invoice, packing list, and certificate of origin (if needed). 5. **Shipping options**: - **Sea freight (Ningbo to Felixstowe)**: 25–30 days transit, roughly $0.70–$1.20 per kg depending on volume. - **Air freight (Shanghai to Heathrow)**: 5–7 days transit, $4.00–$5.50 per kg. 6. **Customs clearance**: your UK broker handles duty and VAT payment. We can send you the HS code recommendation upfront. We also offer **FBA-ready shipping** — we pre-apply Amazon labels and ship directly to the UK fulfilment centre. That’s a common request from our [private label activewear](/private-label-activewear) clients. --- ## Price tiers We don’t hide pricing behind a quote form. Here’s a realistic breakdown of what you’ll pay for a seamless set (sports bra + leggings) FOB Ningbo, based on MOQ and fabric choice. All prices are in USD and assume a standard 260 gsm nylon/spandex blend. | MOQ (pieces) | Price per set (FOB) | Fabric options | Typical lead time (after sample approval) | |--------------|---------------------|----------------|-------------------------------------------| | 1–49 | $15–$20 | Polyester/spandex 220 gsm | 3–7 days (sample only) | | 50–299 | $12–$15 | Nylon/spandex 260 gsm | 4–6 weeks | | 300–999 | $9–$12 | Custom blends, full Pantone colours | 4–6 weeks | | 1,000+ | $7–$9 | Any GSM, any logo (print/embroidery/heat transfer) | 6–8 weeks | **What’s included in the price:** - Custom pattern making from your design or our library. - Logo application (screen print, sublimation, silicone label, or embroidery). - Wash care labels, hang tags, and neck labels with your brand. - Pre-shipment quality inspection report. **What’s not included:** - Freight and insurance. - UK duty and VAT. - Sampling shipping cost (we cover the sample production, you pay shipping). If you want to test a style with just 1 piece, we can do that. Our [low MOQ sportswear](/low-moq-sportswear) page has more details on how we keep costs manageable for startups. --- ## Sizing preferences UK sizing is different from standard Asian sizing. We know from experience that a UK size 8 (XS) expects a waist measurement of 26–27 inches, while a UK size 16 (XXL) needs 36–38 inches. Our standard size chart for seamless sets is based on European measurements, but we can adjust the grading to match your market. **UK women’s seamless set sizing (typical grades we offer):** | UK dress size | Waist (inches) | Hip (inches) | Inseam (leggings) | Bra band (inches) | |---------------|----------------|---------------|-------------------|-------------------| | 6 (XS) | 24–26 | 34–36 | 27” | 28–30 | | 8 (S) | 26–28 | 36–38 | 28” | 30–32 | | 10 (M) | 28–30 | 38–40 | 28” | 32–34 | | 12 (L) | 30–32 | 40–42 | 29” | 34–36 | | 14 (XL) | 32–34 | 42–44 | 29” | 36–38 | | 16 (XXL) | 34–36 | 44–46 | 30” | 38–40 | We can also modify the waistband height (many UK buyers want 9–10 inches for tummy control), the leg opening (avoid riding up), and the bra cup construction (removable padding vs. built-in foam). If you’re targeting the yoga market, you might want a higher rise and a softer waistband — we’ve worked on that for UK-based yoga studios and documented it in our [yoga wear wholesale guide](/pages/yoga-wear-wholesale-guide). **Important note for Amazon sellers:** UK Amazon size charts often require numeric sizing (e.g., 8, 10, 12) rather than S/M/L. We can populate your Amazon listing with the exact measurements and fit descriptions. --- ## FAQ **What is the MOQ for seamless sets?** We have no minimum order quantity. You can order 1 piece for sampling, or 100 pieces for a test run. The pricing scales with volume, but we never turn away a small order. Our 1-piece MOQ includes full customisation — logo, labels, colour, and size. **What is the lead time to the UK?** Sample production takes **3–7 days** (we ship samples via express courier, 3–5 days to the UK). After sample approval, production for an order of 300 pieces takes **4–6 weeks**. Sea freight from Ningbo to Felixstowe adds **25–30 days**, air freight adds **5–7 days**. So total door-to-door for a typical 300-piece order: **8–10 weeks** by sea, **6–7 weeks** by air. --- **Ready to start your seamless set line?** We’re here to answer your technical questions, send a size chart, or provide a quote with duty estimates.
