Complete Guide to Bottle Neck Thread Standards (400, 410, 415, 425, 430)

In the cosmetic packaging industry, 400, 410, 415, 425 and 430 are the most common universal thread specifications. Each type has unique thread turns, neck height and application scenarios, covering sample packaging, daily mass-market products and high-end skincare tubes.
400 Thread Standard
The 400 neck is a simple single-thread structure with fewer thread turns and low thread height. It features easy twisting and quick opening, which is mostly applied to disposable trial tubes, cosmetic samples and low-cost daily packaging. With simple structure and low mold cost, it is the most economical choice for promotional and trial-size cosmetic tubes.
410 Thread Standard
As the most universal mainstream specification, the 410 neck adopts 1.5-turn thread design with moderate height and uniform thread spacing. It balances easy opening and stable sealing performance, perfectly compatible with flip-top caps, disc caps and ordinary screw caps. Widely used in facial cleansers, hand creams and daily personal care tubes, it is the first choice for most mass-market cosmetic packaging.
415 Thread Standard
The 415 neck is designed with double full threads and higher neck height, providing larger thread engagement area and stronger locking force. Compared with 410 type, it has better leak-proof and anti-loosening performance, effectively avoiding liquid leakage during long-distance transportation. It is widely used for high-end skincare products, essential oil formulas and high-viscosity creams that require high sealing safety.
425 Thread Standard
425 neck belongs to enhanced thick-thread specification with deeper thread groove and stronger bearing capacity. It features stable assembly and excellent pressure resistance, suitable for medium and large-capacity cosmetic tubes. It is commonly matched with thickened screw caps, ideal for body lotion, body cream and large-size daily care packaging.
430 Thread Standard
The 430 neck is a high-precision reinforced thread standard with the highest thread density and full engagement structure. It achieves ultra-tight sealing effect and zero loosening rate, perfectly suitable for high-value cosmetic formulas with active ingredients, essential oils and easily oxidized contents. It is the preferred thread type for premium brand high-end packaging and cross-border long-term shipping.
