TL;DR: Buying apparel in bulk from Shenzhen suppliers works differently from placing custom production orders. Stock programs let you order ready-made goods in pre-packed size runs, mix multiple SKUs inside a single carton, and unlock tiered price breaks as your volume climbs — typically 3–5% off per tier, with restock cycles of 7–20 days for in-stock items. This guide breaks down how size-run cartons are packed, how mixed-carton ordering works, what volume thresholds trigger better pricing, and how to plan restocks around realistic lead times from the Pearl River Delta.
Why Shenzhen Works for Bulk Stock Programs
Shenzhen’s advantage as a wholesale sourcing base comes from location. The city anchors the Pearl River Delta supply chain, with sewing operations concentrated in nearby Humen (Dongguan), fabric supply a short trip away at Guangzhou’s Zhongda textile district, and two major export gateways — Yantian and Hong Kong — handling consolidated container traffic daily. Unlike a factory that only produces to order, many suppliers in this region maintain standing inventory of proven styles, which is what makes quick-turn bulk buying possible at all.
For resellers, this changes the economics. Instead of committing to a 90-day production cycle and locking capital into goods that may not sell, you buy finished inventory in sellable assortments, test demand in your market, and reorder only what moves. The trade-off is less customization: colors, fabrics, and sizes are fixed to what’s in stock. For many wholesale buyers — distributors, chain stores, marketplace sellers — that trade is worth it.
Who bulk stock buying suits best
- Distributors filling recurring replenishment orders across multiple store locations
- E-commerce and marketplace sellers who need fast dispatch and predictable availability
- Retail chains topping up core lines (basics, underwear, activewear) between seasonal buys
- New importers testing a category before committing to made-to-order volume

Understanding Size Runs and Carton Ratios
Bulk goods from Shenzhen suppliers are rarely sold as loose pieces. Inventory is pre-packed into cartons using standard size ratios, and understanding these ratios is the single most important skill for calculating real landed cost and sell-through.
Common packing ratios
- Standard run (1-2-2-2-1): six pieces per carton across five sizes — the most common ratio for womenswear knits and loungewear
- Even run (2-2-2 or 3-3-3): three sizes in equal quantity, typical for stretch garments where fit tolerance is wide
- Extended run: plus-size or inclusive programs pack 2XS through 4XL in weighted ratios, since mid sizes turn faster than extremes
- Solid-color cartons vs. assorted cartons: some programs fix color per carton; others mix two or three colorways
When you negotiate, always ask for the ratio in writing. A “cheaper” per-piece price on a skewed ratio (heavy on XS and XL) often costs you more per unit sold than a slightly higher price on a balanced 1-2-2-2-1 run. Match the ratio to your own sales curve — if your data shows 2XL turning faster than the industry norm, request a custom ratio; most Shenzhen suppliers will repack for a small fee or a slightly higher MOQ.
Calculating carton economics
Work backwards from sell-through. If a carton holds 24 pieces across six sizes and your historical size curve is 8-18-30-26-18% (S–XXL), a 1-2-2-2-1 ratio packs well. If it doesn’t match, you’ll tie up cash in slow sizes and stock out of fast ones — which is worse than paying 3% more per piece for the right mix.
Mixed-SKU Cartons: How Assortment Ordering Works
Mixed-carton ordering is where Shenzhen wholesalers diverge sharply from factory-direct OEM. Instead of one style per order, you consolidate several styles, colors, or categories into a single shipment — often to hit a container or minimum order value threshold.
Typical mixed-carton rules
- Per-style minimum: commonly 1 carton (6–48 pcs depending on garment type) rather than a per-piece MOQ
- Order-level minimum: a total value floor — often US$2,000–5,000 for export pricing — across all SKUs combined
- Ratio integrity: you can mix styles, but usually not break the size ratio inside each carton
- Pricing tiers apply at order level: your cumulative volume across SKUs determines the discount bracket, not the volume of any single style
For example, a distributor might combine 10 cartons of seamless light-support lounge bras with 6 cartons of plus-size high-support sports bras to reach the next pricing tier — even though neither line alone would qualify. This is standard practice and worth planning deliberately: split orders cost you money.
Tiered Pricing: What the Breaks Actually Look Like
Tiered pricing rewards consolidated volume. While every supplier sets its own brackets, the structure below reflects what’s realistic for stock-program apparel exported from Shenzhen:
| Order Tier | Typical Discount | Best For |
|---|---|---|
| Entry (below minimum value) | List price | First test orders, new buyers |
| Tier 1 (10–30 cartons) | 3–5% off list | Regular replenishment buyers |
| Tier 2 (30–80 cartons) | 6–10% off list | Regional distributors |
| Tier 3 (80+ cartons / LCL-to-FCL) | 10–15% off, plus better freight rates | Container-order buyers, chain stores |
Two details matter more than headline percentages. First, tiers usually count cumulative orders over a period (often quarterly), not just single shipments — so ask whether repeat orders roll into your tier status. Second, freight changes the math: a 12% product discount can evaporate if splitting an order pushes you from FCL into LCL shipping. Always compare tier pricing on a landed-cost basis.
Negotiating beyond the published tiers
- Commit to a restock schedule (e.g., monthly reorders) in exchange for Tier pricing at lower volumes
- Accept slower-selling colorways alongside bestsellers to hit a bracket threshold
- Consolidate with your own other orders — one 40ft container from Shenzhen prices far better than two LCL shipments
Restock Planning and Lead Times
The whole point of stock buying is speed, but speed only holds if you plan around the supplier’s replenishment reality.
Realistic Shenzhen lead-time benchmarks
- In-stock items, in-production colors: 7–12 days to packing complete, plus freight
- Stock items needing repack or custom ratios: add 3–5 days
- Semi-stock (running styles, made to replenish): 20–30 days
- Peak-season buffering: July–September production calendars fill fast ahead of Q4 holiday retail; place August–October restocks 2–3 weeks earlier than usual
- Freight from Shenzhen/Hong Kong ports: 25–35 days sea to US West Coast or Northern Europe; 5–8 days air for urgent top-ups
The practical rule: reorder when you hit roughly 40–50% of remaining stock, not when you’re nearly out. Because stock programs can sell through on the supplier’s side too, your fastest-selling SKUs are also the ones most likely to be temporarily unavailable. Building a standing reorder cadence with your supplier — and flagging your core repeat SKUs in advance — protects availability better than any contractual guarantee.

Quick FAQ
Can I mix sizes within a carton instead of using the standard ratio?
Sometimes. Many suppliers will repack to a custom ratio for a small surcharge or a higher per-style minimum, but breaking ratios entirely is rare on stock programs since cartons are pre-packed upstream.
What’s the smallest workable bulk order from Shenzhen?
For most stock programs, one carton per style with a total order value around US$2,000–3,000. Below that, per-piece pricing rises and freight efficiency drops sharply.
How do tiered discounts interact with mixed-carton orders?
Tiers are calculated on total order volume or value across all SKUs, so mixing styles to reach a bracket is normal and encouraged — that’s exactly what mixed-carton programs are designed for.
What happens if an in-stock style runs out mid-restock cycle?
Good suppliers flag low inventory before you reorder and suggest a comparable running style. This is another reason to keep your SKU list slightly broader than your bestsellers alone.
Next Steps
Bulk buying from Shenzhen rewards buyers who plan ratios, consolidate volume, and reorder on a schedule rather than in emergencies. Start by reviewing available stock styles, map your size curve against the packing ratios, then reach out with your target volumes to get tier pricing quoted on a landed-cost basis. A modest first order in mixed cartons will tell you more about your market than any forecast — and it sets up your discount tier for every reorder after it.
