400 ml, double-wall vacuum 304 stainless. It is the one with the smallest capacity here, for a child or a light portion, with 4 stock colours to choose from. Custom logo from 500 pieces.
The vacuum layer is what makes this work: with almost nothing left to conduct heat away, hot food stays above serving temperature through a working day, and in the larger sizes you can pour in boiling water and raw rice in the morning and open cooked congee at lunch. The inner wall is 304 stainless throughout — the grade matters because lower grades pick up odours and pass them to whatever goes in next. The closure seals inverted, which is the only test that matters for something that travels in a bag.
In practical terms that means a few specific things: The print carries the product on a crowded shelf, which is what a differentiated SKU has to do. The closure seals under inversion, not merely closes. The closure seals under inversion rather than merely closing, which is the only test that matters for something carried in a bag. Thermal performance holds through a working day rather than fading after the first hour, because the vacuum is drawn properly rather than partially. The interior wipes clean without scrubbing, which matters more on a food container than on a drinks bottle.
Also on the buyer’s checklist here: heat retention, cold retention, consistency, print, nothing coming loose, lid.
Buyers come back to this one for a combination of reasons rather than a single feature: the size lands with the widest slice of end users, which is what a retailer cares about more than any single feature; complaints are rare enough that the buyer stops budgeting for replacements; the colours carry the product on social feeds without extra photography spend; the entry quantity is low enough to trial without a warehouse full of stock. None of those is a claim about the product on its own — they are the reasons a buyer gave when they placed a second order, which is a different and more useful thing.
Also cited on repeat orders: print, looks, heat retention, consistency, students, children, baby food.
Choosing between them
How TW-1003 compares with the rest of the range
Buyers rarely arrive knowing which model they want — they arrive knowing the brief. This table is the fastest way to check whether TW-1003 is the right answer or whether a sibling fits better. The row highlighted is the one you are looking at. Every model listed runs from 500 pieces per design.
Every model above ships from 500 pieces per design. Mixing several of them in one container is normal — a 20ft container holds roughly 26 m³ of cartons, so a mixed load is planned on carton volume rather than on piece count. Send the full list at enquiry rather than model by model.
Who is buying TW-1003, and what they do with it
A stationery shop in Vietnam takes this one for students. The orders themselves are for school procurement.
End uses we actually see: a school lunch that is still hot at midday; baby food carried warm rather than reheated; porridge that finishes cooking on the way; soup; a packed meal; party favours and school-year gifts; shelf retail. Those are the briefs this model was shaped around, and it is why the spec looks the way it does.
Also on the buyer’s checklist here: students, heat retention, packed meals, parents, baby food, porridge, children, event gifts, gifting, retail.
A harder run we did on this model: A buyer in Indonesia placed a large single order with their own logo printed timed to the start of a school year. We ran the line on overtime and moved their batch up the queue, and we worked the freight booking through with them rather than handing it over at the gate. and delivered ahead of the agreed date and it shipped on time They have reordered twice. We mention it because a deadline is the one thing a factory cannot negotiate after the fact — either the line is free or it is not, and knowing which is the useful answer.
Also in play on that job: high volume, print quality, back-to-school, expedited.
Importers & wholesalers
This model packs 30 per carton (62cm×47cm×66cm for the base size — the full carton table is in the spec above), and that number decides how many pieces fit a 20ft container far more than the FOB price does. What decides your landed cost here is the carton, not the unit price: ask for the container plan before you fix a retail price, because a wide-body jar fills a 20ft on volume long before it hits the weight limit. We quote EXW Yongkang, FOB Ningbo or Shanghai, or DDP door to door, and we will say which of the three costs you least given where you are rather than defaulting to whichever is easiest for us.
Brand owners & private label
On TW-1003 the stock range is 4 colours (blue, pink, white, yellow), so a Pantone match is only worth the 1,000-piece run if none of those is close enough. Budget it as three lines, not one: decoration sits inside the unit price, a matched Pantone is its own spray run from 1,000 pieces, and packaging is separate with its own tooling and proofing round. Brands that budget these as a single number are the ones surprised at quotation: decoration sits in the unit price, a matched Pantone is a separate spray run from 1,000 pieces, and a printed colour box carries its own tooling and one proofing round. We sign an NDA before you share artwork, and a shape you tool for stays reserved to you — the same terms we have run with Hallmark since 2017 and with KRAUS for over ten years.
Retail chains
TW-1003 packs 30 per carton, so a 12-store drop lands on a clean carton multiple rather than a split case. Retail-ready means more than a colour box: UPC or EAN printed and scan-tested before the carton is sealed, carton marking to your own packaging manual, and inner counts that match what your DC expects. A barcode that fails at the till becomes a chargeback, and it is entirely preventable at our end: we print and scan-test every UPC or EAN before the carton is sealed. Ask for the retail packaging spec sheet with your first quote — it lists carton dimensions, inner counts and the UPC placement we scan-test before sealing.
Promotional distributors
TW-1003 is a single-capacity line, which is the fastest thing we can turn around when a date is already tight. Work backwards from the in-hands date, not forwards from the order date: 7–10 days for a pre-production sample, about 30 days production after approval, then 30–35 days sea freight to Europe or 25–30 to the US west coast. Production is 30 days after deposit and artwork approval, plus 7–10 days for a printed pre-production sample, plus sea freight — roughly 30–35 days to Europe, 25–30 to the US west coast. Late artwork is normal in this business; a date discovered late is not survivable — artwork approval is what starts the 30-day production clock, not the deposit. Tell us the date at enquiry and we will say honestly whether it is achievable.
Amazon & e-commerce sellers
TW-1003 ships in a 62 cm × 47 cm × 66 cm carton — send us your FBA plan and we will confirm whether that splits cleanly under the dimension cap before you book. FNSKU labels, Prop 65 and suffocation warnings applied here, cartons built to FBA dimension limits, and we can split a shipment across fulfilment centres if you send the plan. Doing it at the factory removes a prep-centre handling fee and about a week of transit on every restock. Watch dimensional weight on this category — the carton is light for its size, so FBA usually bills on volume.
End users & institutions
On TW-1003 laser engraving is the safe call for daily institutional washing. Canteens, schools and site catering wash hard and often, and this category goes through more of it than a drinks bottle because it holds food. Laser engraving costs slightly more up front and removes the complaint entirely: the mark is cut into the steel and reads the same after a season of commercial dishwashing, while printed artwork on a coated body visibly fades.
Failures we hear about from buyers who switch to us
Almost every buyer who moves this product to us arrives with the same list of complaints about a previous supplier. Worth knowing whoever you end up buying from.
✓
Coatings that chip
Cheap outer paint scratches through within weeks and the product looks second-hand on a shelf long before it stops working.
✎
A vacuum that fades
A weak draw passes a same-day test and disappoints two months later. We check vacuum integrity on 100 % of bodies as semi-finished parts — before assembly, before coating — because on a finished branded unit the flaw stays invisible until it becomes your customer’s problem.
⚑
Lids that do not lock
The most common complaint we inherit: a container that seeps into a bag once is never bought again. Ask any supplier to run an inverted seal test with liquid in it, not just show you the gasket.
Where TW-1003 is actually made
Eight workshops in Yongkang, Zhejiang, running since 1998 — mould development, vacuum welding, injection moulding, spray painting, laser marking, printing, assembly, inspection and packing, all in one building. For TW-1003 the stage worth watching is the vacuum draw and the wide-mouth seal.
A food jar is harder to build than a drinks flask for one reason: the mouth is wide, so the sealing surface is long and the liner has a bigger opening to close around. We draw the vacuum on the liner as a semi-finished part and test it there — before assembly, before coating, before your logo goes on. A weak draw passes a same-day test and fails two months later, and on a finished, printed, shipped jar that flaw is invisible until it is your customer’s problem. The second bench that matters is the inverted seal test: liquid in, lid on, upside down. We run it because a jar that seeps congee into a laptop bag is returned once and never bought again.
We inspect 8% of every batch rather than a fixed sample per shipment. Buyers are welcome on site — eight workshops in Yongkang, Zhejiang, running since 1998, about three hours by road from Ningbo port and two from Hangzhou airport, which makes a factory visit a realistic side trip rather than a separate journey. Ask to see that bench specifically; it is where the difference shows — we check vacuum integrity on 100% of bodies at the semi-finished stage, before assembly and coating, because a micro-leak is undetectable once the jar is built.
Is TW-1003 the right one for your programme?
Importers & wholesalers — Workable from 500 pieces per design. At 30 pcs per 62cm×47cm×66cm carton, a 20ft container takes roughly 4,000 pieces of this model alone — worked from the biggest of this model’s carton sizes, and confirmed on the pro forma once the load plan is fixed. Tell us the full model list at enquiry rather than one at a time — the quote changes when several models share a colour run or a carton size.
Brand owners & private label — Yes. Three separate lines to budget: the logo sits in the unit price, a matched Pantone is its own run at 1,000 pieces, and packaging is third — this model ships in a printed colour box as standard, and anything else is a separate tooling and proofing round.
End users & institutions — Suited to schools and campus retail. For institutional buying, specify laser engraving rather than print — a printed logo on a coated body typically fades within one season of daily commercial dishwashing, while an engraved mark is cut into the 304 steel and does not.
Not the right pick if… — the end user is an adult wanting a full meal. At 400 ml this is a child or light-lunch portion; the 800 ml models in the same range are the adult size.
FAQ
Ordering TW-1003 — common questions
Why TW-1003 rather than another model in this range?▾
This one runs 400 ml, and it is the one with the smallest capacity here, for a child or a light portion, with 4 stock colours to choose from. End users are parents carrying baby food and warm porridge, baby and toddler food, students and school lunches, supermarket retail, gifting programmes. If your brief is different from that, say so in the enquiry — we would rather point you at a sibling model than sell you this one and have it come back.
How long does TW-1003 keep food hot?▾
At 400 ml, expect around 6 hours with a full fill, less if it is opened repeatedly or only half filled. The double-wall 304 stainless body is the reason: with the air drawn out between the walls there is almost nothing left to conduct heat away. Two habits worth printing on your packaging — rinse with boiling water before filling, and fill it as close to the top as practical.
Which colours can we order TW-1003 in?▾
Stock colours are blue, pink, white, yellow — those run from 500 pieces per design. A matched Pantone is a separate spray or resin run and starts at 1,000 pieces. Mixed-colour containers are normal here: several buyers deliberately split a container across colours to see which ones move before committing to one.
How do we brand TW-1003?▾
Laser engraving is what we would recommend for anything washed daily — the mark is cut into the metal, so there is nothing on the surface to strip. The trade-off is one tone in the colour of the steel, not your brand colour. For colour, silk screen runs one to three flats and UV digital handles photographic artwork, both onto a sprayed body.
What is the MOQ, lead time and carton spec for TW-1003?▾
From 500 pieces per design in stock colours; a matched Pantone starts at 1,000 because a custom colour means a dedicated run. Production runs 30 days after deposit and artwork approval, sample in 7–10 days. Packing is 30 pcs per carton at 62cm × 47cm × 66cm. We quote EXW Yongkang, FOB Ningbo or Shanghai, or DDP if you would rather we handled duty and delivery.
Do you supply a thermos bottle and food jar as a set?▾
Yes — a thermos bottle and food jar set is one of the most common gift and welfare-pack briefs we quote. TW-1003 is the 400 ml children’s food thermos size; pair it with a matching flask from our TI range and we quote both together, packed in one box with one carton plan. Say at enquiry whether the two need matching colours — body colour is a spray run, so matching across two product families is a scheduling decision, not just a colour choice.
