What is your Minimum Order Quantity (MOQ) for custom OEM and stock orders?

For blank stock drinkware items and sublimation blanks, our MOQ starts at just 100 pieces for immediate dispatch. For custom logo laser engraving or silk-screen branding on standard colors, the MOQ is 300 to 500 pieces. For custom Pantone color matching (PMS powder coating) or customized packaging boxes, the MOQ is 1,000 pieces. For custom private mold tooling and proprietary shapes, our typical production run starts at 3,000 pieces.

How does Unifan guarantee vacuum insulation performance and thermal retention?

Every single stainless steel bottle and tumbler undergoes our mandatory 100% two-step vacuum testing procedure. After the automated 10^-3 Pa high-temperature vacuum brazing furnace process, products pass through automated infrared thermal imaging scanners to verify absolute vacuum integrity. We guarantee our double-wall vacuum products maintain boiling liquids hot for 12 to 24 hours (temperature above 55°C) and ice water cold for 24 to 48 hours.

Are your drinkware products and lids certified for FDA, LFGB, and California Prop 65?

Yes. All products manufactured by Quanzhou Unifan comply with strict international food safety standards. Our stainless steel alloys (SUS304 and medical-grade SUS316) and BPA-free Tritan/PP lids are tested annually by SGS, TÜV Rheinland, and Bureau Veritas, fully complying with US FDA 21 CFR 175.300, German LFGB (§ 30 and 31), and California Proposition 65 (zero lead, cadmium, or phthalates). Full test reports and Declaration of Conformity (DoC) dossiers are provided upon request.

What is the difference between SUS304 (18/8) and SUS316 stainless steel for water bottles?

SUS304 (also known as 18/8 stainless steel, containing 18% chromium and 8% nickel) is the global gold standard for food-grade drinkware, offering exceptional corrosion resistance and mechanical strength. SUS316 contains an additional 2% to 3% molybdenum, which provides enhanced resistance against chloride pitting and acidic liquids such as coffee, citrus juices, electrolyte sports drinks, and tea. We offer SUS316 inner liner upgrades across all our vacuum flasks and food jars.

Are your powder-coated water bottles and tumblers dishwasher safe?

Yes. Our automated electrostatic powder coating lines utilize automotive-grade polymer resins cured in precision thermal ovens. Our coated bottles undergo ASTM D3359 and ISO 2409 Class 0 cross-hatch tape adhesion tests and withstand 50+ cycles in commercial dishwashers without blistering, peeling, or fading. For products featuring delicate metallic foil decals or vacuum electroplating, gentle hand washing is recommended.

How long does it take to open a new private mold, and how is IP protected?

Custom private mold tooling for new bottle shapes or proprietary lids requires 15 to 20 working days from final CAD sign-off. We sign legally binding Non-Disclosure Agreements (NDA) and Non-Compete agreements prior to receiving client drawings. Tooling fees can be fully amortized and refunded once aggregate order volumes reach agreed thresholds (typically 30,000 to 50,000 units). Clients retain 100% proprietary ownership of their custom molds.

Can I receive functional 3D prototypes or pre-production samples before placing a bulk order?

Yes. We offer rapid digital SLA and CNC metal prototyping within 3 to 5 business days. This allows your team to physically evaluate ergonomics, liquid flow dynamics, lid threading, and finish aesthetics before committing to steel tooling. Pre-production samples with custom logo laser engraving or digital UV printing can be expedited within 5 to 7 days.

What surface treatments and logo branding methods do you support?

Our automated finishing facility supports: (1) Electrostatic Matte and Gloss Powder Coating, (2) 3D and 4D High-Definition Digital Cylinder UV Printing for tactile 360° graphics, (3) High-Speed Fiber Laser Engraving, (4) Silk-Screen and Pad Printing, (5) Water Transfer (Hydro Dipping) for marble and wood-grain textures, (6) Gas Sublimation Coating for photo-realistic heat transfers, and (7) Food-Grade Ceramic Non-Stick Interior Lining.

Which shipping terms do you support, and do you handle direct Amazon FBA delivery?

We regularly export under FOB Xiamen, FOB Shenzhen, CIF, CFR, and DDP terms. For e-commerce sellers on Amazon, Shopify, and TikTok Shop, we provide comprehensive turnkey DDP shipping direct to Amazon FBA fulfillment centers across the United States, Canada, the United Kingdom, Germany, and Australia. We handle customs clearance, import duties, palletization, FNSKU barcode labeling, and box carton labeling.

What is your defect allowance, and how do you handle defective items?

Our automated manufacturing process maintains an industry-leading defect rate below 0.3%. All shipments are inspected according to ISO 2859-1 (AQL 1.0 Critical / 2.5 Major). In the rare event of a manufacturing defect (such as loss of vacuum insulation), we provide a 1:1 free replacement on your next shipment or an immediate credit note, backed by our 12-month manufacturer quality warranty.

What payment terms do you offer for international B2B wholesale orders?

Our standard commercial terms are 30% T/T deposit upon order confirmation and 70% balance payment against the Bill of Lading (B/L) copy after pre-shipment inspection. For established brand clients and high-volume corporate partners with long-term cooperation records, we accept Irrevocable Letters of Credit at Sight (L/C at Sight) and flexible Open Account (OA) terms through Sinosure export credit insurance.

What sustainable materials and eco-friendly packaging options are available?

Unifan is committed to environmental sustainability. We offer products made with up to 90% Post-Consumer Recycled (PCR) stainless steel, infinitely recyclable aluminum party cups, and biodegradable bamboo lid caps. For packaging, we provide 100% plastic-free biodegradable kraft paper boxes, FSC-certified cardboard packaging, and water-based soy ink printing to meet European and North American carbon reduction regulations.

How do universal 4-in-1 stainless steel can coolers function across different can sizes?

Quanzhou Unifan's 4-in-1 can coolers use a patented food-grade threaded silicone/PP adapter collar. When inserting a standard 12oz beer can, the silicone gasket grips the rim securely. For 12oz skinny hard seltzer cans, the collar slides down internally to maintain tight surface contact. For standard 12oz glass beer bottles, the top ring secures the neck. Furthermore, by removing the adapter and using an optional splash-proof slider lid, the cooler converts into a fully functional 14oz vacuum cocktail tumbler.

Why are stainless steel protein shakers superior to conventional plastic gym shaker bottles?

Standard plastic polypropylene shakers absorb whey proteins, milk fats, and bacteria over time, resulting in permanent rancid sour odors and microplastic shedding. Quanzhou Unifan's protein shakers feature electro-polished 18/8 (SUS304) stainless steel inner chambers that are non-porous and naturally antibacterial. Coupled with medical-grade SUS316 surgical wire whisk balls, they pulverize thick powders in seconds and can be sanitized in boiling water or dishwashers with zero odor retention.

What thermal retention capabilities do your commercial double-wall coffee carafes offer?

Our commercial coffee carafes feature double-wall 18/8 stainless steel construction brazed under ultra-high vacuum (10^-3 Pa) with internal electrolytic copper plating. Filled with 95°C hot coffee at room temperature (20°C), the beverage remains above 78°C after 6 hours and above 65°C after 12 hours. The one-touch thumb push button activates a silicone spring seal that opens solely during pouring, drastically reducing ambient heat transfer compared to open pour pots.

Can your craft beer growlers and mini kegs hold draft pressure without beer going flat?

Yes. Quanzhou Unifan's 64oz and 128oz stainless steel growlers are pressure-tested up to 45 PSI. The heavy-gauge swing-top mechanism utilizes food-grade vulcanized silicone O-rings that lock in CO2 carbonation for up to 48 hours after filling at the tap. For commercial craft beer distribution, we also offer mini keg systems fitted with integrated CO2 gas regulators and draft faucets to pour fresh foamy pints continuously.
