Key takeaways.
- Indicative clearance band: stainless vacuum flasks and tumblers (200–1500 ml) typically clear at about USD 0.8–4.5 per piece in the stock-lot channel, versus several times that for comparable first-run wholesale.
- Branded OEM surplus discounts deepest: lots from large makers such as Haers, Tafuco, Fuguang, SHINETIME routinely beat the generic 30–70% discount band because the first-run channel is restricted while the secondary market is not.
- Vacuum is the product — test it: the single highest-risk defect in flask stock is failed vacuum; demand a live ice/water test on random-carton samples before payment.
- MOQ is naturally low: goods are finished, so lots often start at one pallet; many listings show MOQ from 100 pcs, with 40–100 pcs mixed-colour cartons typical for branded surplus.
- Lid mismatch is the most common inspection finding — count lids against bottles and confirm inner packing before committing to a container.
1. Why vacuum drinkware floods the surplus channel
China's vacuum-ware belt — Yongkang, Jinhua and the wider Zhejiang cluster — is the world's largest producer of stainless steel flasks and tumblers, with thousands of factories running speculative production alongside export orders. Three events push finished drinkware into the stock-lot channel:
- Cancelled export orders. A finished container that misses its sailing window or fails the buyer's final inspection becomes liquidation stock.
- Over-production against forecasts. Factories over-run popular sizes and colours to keep unit costs down; the overshoot has no home channel.
- Retail packaging resets. When a brand or chain changes artwork or gift-box design, the old-SKU inventory must clear fast.
The practical consequence: vacuum drinkware is one of the few categories where below-cost buying is structurally normal, because warehousing bulky metal goods costs sellers money every month.
2. Indicative pricing by size and grade
The table below reflects how flask stock lots commonly clear in negotiation. Treat the ranges as indicative composites — every lot has its own live price depending on quantity, brand and condition.
| Type | Typical lot contents | Indicative range (USD/pc) | Notes for buyers |
|---|
| Stainless vacuum flask / thermos | 500–1500 ml, branded or plain | $1.5 – $4.5 | Confirm 304/316 inner wall; ask for capacity tolerance in writing |
| Insulated tumbler / coffee cup | 300–600 ml, lid types mixed | $0.8 – $3.0 | Lid count vs bottle count is the #1 mismatch — verify per carton |
| Kids' bottle with straw | 350–600 ml, silicone parts | $0.9 – $2.5 | Silicone ages; check date of manufacture and food-contact docs |
| Travel mug / office ware | 400–500 ml, handle models | $1.0 – $3.5 | Bulky gift boxes raise freight — get carton dimensions before price |
| Single-wall / non-vacuum bottle | sports bottles, steel bottles | $0.3 – $1.2 | Not comparable to vacuum ware; price accordingly, do not confuse grades |
| Gift-set flasks (2–4 pcs box) | branded gift cartons | $3 – $9 /set | Best margins in Q4; packaging condition drives resale value |
Ranges are indicative composites from lot negotiations, not quotations. Every lot on stock-clearance.ai shows its own live price or accepts inquiry.
3. Branded OEM surplus: the 2026 sweet spot
A recurring pattern in the Zhejiang belt: surplus and cancelled-export stock of branded stainless drinkware produced by large OEM factories — Haers (哈尔斯), Tafuco (泰福高), Fuguang (富光), SHINETIME (雄泰) — surfacing at deep discounts. Discount retailers and online resellers buy it because:
- tooling and vacuum quality are factory-grade, well above no-name surplus;
- cartons are export-standard, usually 40–100 pcs per carton with mixed colours;
- the discount versus normal branded wholesale can exceed the typical 30–70% band, since the original channel is restricted but the secondary market is not.
Trademark note: brands are mentioned for identification of goods in the secondary market. Trademarks belong to their owners; lots are surplus stock, not authorised first-run retail goods. Confirm your destination market's resale rules before importing branded items.
4. Grading: what A/B/mixed means for drinkware
- Grade A: complete, unscratched, retail-ready with intact inner boxes. Usually cancelled export orders — the highest-priced stock tier.
- Grade B: functional but with cosmetic marks, dents on the base, or worn gift boxes. The volume tier; repack or sell through discount channels.
- Mixed/customer-return lots: unpredictable composition and the highest defect risk. Only buy after a live video count, and price assuming 10–20% unsellable.
Ask the seller to state the grade in writing and to define it — "A grade" means nothing until both sides agree what it excludes.
5. Pre-payment QC checklist
- Vacuum test on video: ice retention or hot-water test on samples from random cartons, not from the showcase box.
- Material grade in writing: 304 or 316 stainless inner wall; food-contact documentation for EU/US resale.
- Lid-to-bottle count match per sampled carton — the most common inspection finding in this category.
- Date of manufacture: silicone seals and coatings age; very old stock (3+ years) warrants a deeper discount.
- Carton dimensions before price: drinkware is dense but gift-boxed sets are bulky; freight can erase a per-piece bargain.
- Third-party inspection for container-size orders: typically USD 100–200 per man-day in the Yongkang/Jinhua/Yiwu belt, and it routinely pays for itself.

Frequently asked questions
How much do vacuum flask stock lots typically cost per piece?
Indicative clearance ranges for stainless vacuum flasks and tumblers typically run from about USD 0.8 to USD 4.5 per piece depending on size (200–1500 ml), grade and whether the lot is branded OEM surplus or plain factory stock. Single-wall bottles trade materially lower.
Why is branded vacuum drinkware often discounted deeper?
Surplus lots produced by large OEM makers such as Haers, Tafuco, Fuguang and SHINETIME are factory-grade in quality, but trademark owners restrict the first-run channel while the secondary market is not restricted — so branded surplus can clear below the typical 30–70% discount band. Trademarks belong to their owners; lots are surplus, not authorised first-run goods.
How do I test vacuum performance before paying?
Ask for a live video of an ice-retention or hot-water test on samples from random cartons, get the inner-wall material grade (304/316) in writing, and for container-size orders book third-party inspection — typically USD 100–200 per man-day in the Yongkang/Jinhua/Yiwu belt.
What MOQ should I expect?
Because flasks are already produced, lots commonly start from one pallet or a few hundred cartons; many listings on stock-clearance.ai show MOQ from 100 pieces. Mixed-colour cartons of 40–100 pcs are typical for branded surplus.
What should I check on lids, packaging and compliance?
Count lids against bottles (lid mismatch is the most common finding), confirm inner boxes are export-grade, and for EU/US resale confirm food-contact documentation. Branded lots additionally require a check of your destination market's resale rules.
