Seamless Sets Wholesale Supplier in US – Zero MOQ Factory

# Seamless Sets Wholesale Supplier in US: What Our 20‑Year Factory Tells US Buyers Your landed cost spreadsheet keeps showing a gap. You’ve seen seamless sets retailing for $35–$45, but after you factor in the tariff hit, air freight, and Amazon’s referral fee, the margin collapses unless you can lock in a factory‑direct FOB under $12. That’s the math that wakes up a brand founder at 2 a.m. And it’s why we’re writing this the way we’d brief a new client on a WeChat call: no fluff, just the numbers, the timelines, and the signals our US buyers are sending us right now. We’re Alpinario, a 20‑plus‑year sportswear factory in Zhejiang. We run our own cutting floor, our own sample room, and our own QC line. We’re not a trading company. Every seamless set we ship to California, Texas, or an Amazon FC in Joliet comes off a line we control. That means when you ask, “Can you hold the waistband stretch to within 5% of the tech pack?” we can answer from the floor, not from a forwarded email. --- ## Market demand signals The switch from “we might test seamless” to “we need a reliable seamless sets wholesale supplier in US” has accelerated sharply in the last 18 months. Our inbound inquiry volume for seamless sets is up over 40% year‑on‑year across our [wholesale sportswear](/wholesale-sportswear) contact forms. The requests cluster around a few clear signals, and we track them because they dictate what we pre‑stock in our yarn library and how we set our sample‑room priorities. **Top‑5 feature requests from US buyers (Q1–Q2 2025):** 1. **Ribbed seamless fabric** – 180–220 GSM, with a 4‑way stretch that won’t sheer out when a customer squats. Almost every startup brand that writes us asks for a ribbed option first. 2. **Scrunch butt detailing** – This isn’t a fad anymore. If your set doesn’t have a ruched seam at the back, you’re competing in a much smaller pool. 3. **Two‑piece sets with a long‑sleeve crop and high‑waist legging** – The set, not the standalone legging, drives AOV. We see 70% of our seamless orders now placed as coordinated sets. 4. **Custom‑dyed matching sets in 6‑8 Pantone shades per drop** – Brands want small batches of color stories. They don’t want to warehouse 2,000 units of a single colorway. 5. **FBA‑ready packaging** – Pre‑labeled cartons, poly‑bagged with suffocation warnings, and a barcode that scans right off the pallet. We’ve been doing this for three years; it’s table stakes now. The search volume side mirrors what we see on the floor. While we don’t run a data‑scraping operation, our clients tell us that terms like “seamless workout set wholesale USA” and “seamless set vendor low MOQ” now drive a meaningful chunk of their discovery. What’s changed: the buyer is no longer a gym with 12 locations doing a branded employee kit. It’s a solo founder who needs 50 sets to test a Shopify landing page before she commits to a container. That’s a different sourcing rhythm, and it’s why our [low‑MOQ sportswear](/low-moq-sportswear) workflow exists. --- ## Import duties & shipping This is the section where a brand’s unit economics either hold or break. We cannot give you a binding customs ruling—we’re a factory, not a broker—but we can share the HS code framework and shipping lanes we see our US accounts use every week. **Typical HS classification for seamless sets:** Most two‑piece seamless activewear sets (knitted, synthetic fiber) fall under 6114.30.30 (women’s or girls’ garments of man‑made fibers, knitted). The base duty rate can be 28–32% depending on the exact fiber composition. Then, because the country of origin is China, an additional 25% Section 301 tariff applies on many of these garment lines. In practice, the total effective duty rate on the CIF value often lands between 53% and 57%. That’s a hard number to swallow, but it’s consistent across all Chinese factories. There’s no secret workaround; your landed cost model must build it in from day one. **Shipping options we coordinate every week (from our Ningbo/Shanghai port to US West Coast):** | Method | Transit time | Cost per kg (approx., 2025) | Best for | |--------|--------------|------------------------------|----------| | Express air (DHL/UPS) | 3–5 business days | $5.50–$7.00 | Samples, rush 50‑unit restocks | | Consolidated air freight | 7–10 days | $3.50–$4.80 | 100–300‑piece medium orders | | LCL sea freight | 22–30 days | $1.80–$2.50 | 300–800‑piece shipments | | FCL sea freight (20GP) | 22–28 days | $0.80–$1.20 | 2,000+ sets | If you’re selling on Amazon, the math usually pushes you toward LCL sea freight for the first restock after the launch batch. We can pre‑apply FBA labels here on the floor, so your cartons go straight from port to FC without a prep center. That’s a hard cost you remove from your P&L. **Step‑by‑step import flow we recommend for a first‑time US buyer:** 1. Confirm a pre‑production sample (3–7 days) and approve the fit. 2. We ship the sample via express so you can check drape and stretch in hand. 3. You file for an HS code ruling with your broker while we produce the order (4–6 weeks for 300 sets). 4. We consolidate and ship LCL to a West Coast port; you clear customs and truck to your 3PL or straight to Amazon. 5. You reorder in larger quantity once you have sell‑through data, shifting to FCL to bring the per‑unit freight down. --- ## Price tiers Our FOB prices scale with order volume. Because we’re a factory floor, not a middleman, we can give you a single price continuum that accounts for sampling, embellishment, and packaging. All prices below are for a standard women’s seamless set (leggings + crop top) in 200 GSM nylon/spandex, with a basic solid color and no logo. Ribbed fabric, custom logos, and special hang tags add small incremental costs. | Order quantity | FOB price per set (USD) | Typical lead time (after sample approval) | Notes | |----------------|--------------------------|-------------------------------------------|-------| | 1–10 pieces (sample/prototype) | $18–$22 | 3–7 days to ship | Includes pattern work and one revision. | | 50–100 pieces | $14–$17 | 3–4 weeks | Can mix 3 colorways. | | 100–300 pieces | $11–$14 | 4–5 weeks | Most common startup launch quantity. | | 300–600 pieces | $9–$12 | 4–6 weeks | Eligible for our FBA prep service. | | 600–1,200 pieces | $8–$10 | 5–7 weeks | Significant per‑unit freight savings via LCL. | | 1,200+ pieces | $7–$9 | 6–8 weeks | FCL shipping becomes the default. | **Add‑ons we handle in‑house:** - Logo application (screen print, heat transfer, or embroidery): $0.50–$1.20 per piece. - Custom woven labels, care labels, and hang tags: $0.15–$0.35 per set. - Poly‑bagging with FBA barcode and suffocation warning: $0.10–$0.15 per unit. If you’re looking for a private label activewear model, we can guide you through the full custom development. Our [private label activewear](/private-label-activewear) page walks through the process, but the short version is: send us a tech pack or a reference sample, and we’ll return a physical spec sample in under a week. No MOQ. No retainer. You only pay for the sample and freight. --- ## Sizing preferences US buyers consistently ask for a size set that skews toward the middle of the bell curve—S, M, L, XL—with a grading that reflects real‑world body shapes, not an Asian fit. We’ve developed a US‑specific grading rule based on thousands of sets shipped to the West Coast and Midwest. Our default US grading table for seamless sets: | Size | Bust (in) | Waist (in) | Hip (in) | Inseam (in) | Torso length (in) | |------|-----------|------------|----------|-------------|-------------------| | XS | 30–32 | 23–25 | 33–35 | 24.5 | 14.5 | | S | 32–34 | 25–27 | 35–37 | 25 | 15 | | M | 34–36 | 27–29 | 37–39 | 25.5 | 15.5 | | L | 36–38 | 29–31 | 39–41 | 26 | 16 | | XL | 38–40 | 31–33 | 41–43 | 26.5 | 16.5 | If your brand serves a specific demographic—say, a curvier fit or a junior cut—we can adjust the grade rule during the sampling phase. The key is to send us a size spec early, not at the production PO stage. We’ve seen too many founders approve a sample in size Medium, then ask for a full size run to be drafted after the production fabric is already cut. That adds 10–14 days and disrupts the dye‑lot matching. We strongly recommend ordering a single full‑size‑run sample set (XS–XL) before you commit to bulk. Yes, it’s an extra $90–$110 in sample costs, but it’s the cheapest insurance against a wave of returns. --- ## FAQ **What’s your MOQ for seamless sets?** Our MOQ is 1 piece. You can order a single prototype set, test the fit, and then scale to 50, 300, or 1,200 sets without ever hitting a minimum wall. We’ve built a [low‑MOQ sportswear](/low-moq-sportswear) process that makes this economically viable for startups and Amazon sellers. **What’s the lead time to the US?** - **Sample:** 3–7 days to ship from our floor, plus 3–5 days in transit via express courier. Plan on 7–10 calendar days from request to in‑hand. - **Production (medium order, 300 sets):** 4–6 weeks after sample approval. - **Shipping:** Express air adds 3–5 days; LCL sea freight adds 22–30 days to a West Coast port. Total door‑to‑door for a 300‑set LCL order: roughly 8–10 weeks. For a 1,200‑set FCL order: 10–12 weeks. **Can you handle custom logo placement and labeling?** Yes. We apply screen prints, heat transfers, and embroidery. We also produce custom woven neck labels, care labels, and hang tags. All of this is done in‑house or through our adjacent print shop, so there’s no 3‑day delay while a subcontractor does the work. **Do you ship directly to Amazon FBA?** Yes. We pre‑apply FBA labels, poly‑bag with the required warnings, and pack cartons to Amazon’s spec. You provide the FBA label PDFs, and we do the rest. **What if I need a custom fabric or a specific Pantone color?** We work with polyester and nylon bases, and we can dye to almost any Pantone reference. For custom fabric textures (ribbed, jacquard, waffle), we’ll develop a strike‑off and send you a swatch before cutting. Allow 3–5 extra days for a custom dye match. --- We’re not a sourcing office that will tell you “everything is possible” and then go silent when the container hits customs. We’re the factory floor. When you visit our [custom sportswear](/custom-sportswear) page, you’re not looking at a curated catalog from a dozen different mills; you’re looking at garments we stitch, press, and inspect ourselves. If you’re ready to put a number to your landed cost, or if you just need a single sample set to validate the fit before you launch, write to us. We’ll answer within 24 hours.
