Custom 18/8 Stainless Steel Bottle Manufacturer: Certified FDA & LFGB Compliant
Don’t risk your brand reputation with inferior materials. We manufacture exclusively with certified 18/8 (SUS304) food-grade stainless steel to ensure purity, durability, and zero metallic taste.
Why Choose ChillTitan for Your Stainless Steel Manufacturing?
As a quality-focused custom 18/8 stainless steel bottle manufacturer, ChillTitan guarantees material integrity. Not all steel is created equal; using cheaper substitutes risks rust and compliance failures. Here is how we guarantee the safety and quality of your product:
Incoming Material Spectroscopy
We don’t just trust suppliers; we verify. Every batch of raw stainless steel tubes is tested with a handheld XRF spectrometer upon arrival to confirm the chemical composition (18% Chromium, 8% Nickel) before cutting.
Electrolytic Polishing for Hygiene
Microscopic imperfections trap bacteria. We use an advanced electropolishing process on the inner walls of every bottle. This creates a mirror-smooth, non-porous surface that resists odors, staining, and bacteria buildup.
100% Lead-Free & BPA-Free
Safety goes beyond the steel. Our vacuum sealing process is completely lead-free, and all plastic lids are molded from virgin BPA-free polypropylene, ensuring your product is fully compliant with California Prop 65.

From Stainless Tube to Certified Product in 4 Steps
We manage material integrity through four distinct stages: Tube Verification & Shaping, Vacuum Insulation & Copper Plating, Surface Finishing & Branding, and Lab Testing & Final Inspection. We ensure consistency and performance at every step.
Tube Verification & Shaping:
Production begins with verifying the 18/8 grade of the incoming stainless steel tubes. We then use advanced hydroforming (water expansion) techniques to shape the inner and outer bottles without thinning the material walls, maintaining durability.
Vacuum Insulation & Copper Plating:
We plate the inner bottle’s exterior with copper before vacuum sealing. This extra step reflects heat radiation, boosting thermal performance to keep drinks cold for 24+ hours and hot for 12+ hours.
Surface Finishing & Branding:
Whether you choose raw brushed steel or a durable powder coat, our finishing lines are dust-controlled to prevent contamination. Your logo is applied with precision, ensuring it meets the premium standard of the underlying material.
Lab Testing & Final Inspection:
Before shipment, random samples are sent to third-party labs (SGS/TUV) for food contact testing. Internally, we perform 100% vacuum insulation testing and visual inspections to reject any defects.
Full Customization Options for Your 18/8 Line
Combine premium materials with world-class customization across four key areas: Raw & Coated Finishes, Permanent Laser Marking, Inner Wall Options, and Material Upgrades & Accessories. This allows you to build a bottle that looks as good as it performs.
Raw & Coated Finishes:
Showcase the material with a raw Brushed Stainless finish, or choose DuraGrip™ Powder Coating for color and grip. We also offer Soft-Touch Rubber and High-Gloss automotive grade paints.
Permanent Laser Marking:
Laser Engraving is the perfect choice for 18/8 steel, revealing the silver material beneath the paint for a permanent, chemical-free mark. We also offer Rotary Screen Printing and 3D Water Transfer.
Inner Wall Options:
Stick with our standard Electropolished interior for maximum hygiene, or choose an optional Ceramic Coating for brands targeting coffee and tea drinkers who demand absolutely zero flavor transfer.
Material Upgrades & Accessories:
Enhance your product with Stainless Steel Lids (bamboo or steel top), color-matched Silicone Boots for base protection, and Gift Tube Packaging that highlights the premium material specs.

Manufacturing FAQs: Material & Safety
Technical answers about steel grades, purity testing, and compliance.
1. What is the actual difference between 304 (18/8) and 201 stainless steel?
18/8 (304) contains 8% nickel, whereas 201 contains almost no nickel. The nickel content is crucial because it forms a passive layer that prevents rust and metallic taste. We strictly use 18/8 for all food-contact surfaces, while 201 is a cheaper, lower-quality alternative we avoid for premium brands.
2. Do you provide material certificates with the shipment?
Yes, we provide a Mill Test Certificate (MTC) for every steel batch. This document verifies the chemical composition (Chromium/Nickel ratio) matches SUS304 standards. We also welcome third-party onsite material testing by SGS or Intertek before shipping.
3. Are your vacuum bottles 100% lead-free?
Yes, we utilize a lead-free glass sealing material for the vacuum process. While some older manufacturing methods use lead solder beads to seal the vacuum hole, our modern process ensures the entire bottle is lead-free and fully compliant with California Prop 65.
4. How do you ensure the steel won't rust?
We perform a 24-hour Neutral Salt Spray (NSS) test on random samples. In addition to using genuine 18/8 steel, we perform electropolishing to remove surface impurities, ensuring maximum corrosion resistance even in humid environments.
5. Can you manufacture with Recycled Stainless Steel?
Yes, we offer RCS (Recycled Claim Standard) certified recycled 304 stainless steel. This allows your brand to make verifiable sustainability claims without compromising the durability or food safety of the product.
6. Is 18/8 stainless steel dishwasher safe?
The raw 18/8 stainless steel material itself is 100% dishwasher safe. However, if you choose a custom finish (like standard powder coating or water transfer), we recommend hand washing to preserve the paint lifespan, unless you specify “dishwasher-safe coating” in your order.
