Customization
One-stop sock supply from design to delivery
Kaixin has built a one-stop service chain covering design, sampling, production and delivery. The direct-from-factory model removes intermediaries and delivers strong value for money.
Design and sampling are handled by our in-house process and pattern engineers, who adjust patterns, colourways, sizes and packaging to match your brand guidelines. Volume production runs on our own 60 machines, so lead time and quality stay under the factory's direct control.
What the service covers
- Style customization: patterns, motifs and colours freely combined to match your brand.
- Size customization: adjusted by foot length or age group, covering 0-12 years and adults.
- Fabric customization: cotton content from 60% to 80% plus functional fibres such as antibacterial or mulberry silk.
- Packaging customization: brand labels, hangtags and polybags aligned to your VI system.
- Function customization: anti-slip dot coating, antibacterial, moisture-wicking and thermal options.
- OEM labelling: produced to your brand standard, process and packaging specification, from 5,000 pairs.
- ODM development: in-house new patterns, fits and colourways with selection and revision support.
- Sample-based customization and fast sampling: replicate or refine your sample to shorten time to market.

FAQ
Common questions about sourcing and customization
Answers on MOQ, sampling lead time, safety standards and delivery methods.
-
Is there a minimum order quantity for a first order, and how large is it?
Orders and delivery
OEM labelling starts at 5,000 pairs and custom styles start at 2,000 sets. Kaixin also supports low-MOQ light customization and small in-stock purchases, so smaller merchants and startup brands can run a trial order first, validate market response and then move into volume production without committing to large inventory up front.
-
Can you produce a sample, and how long does sampling take?
Customization and sampling
Yes. Because Kaixin owns all 60 knitting machines and its technical team, sampling does not queue behind an external factory. Pattern files can be imported straight into the machines to verify needle selection, and the sample is delivered once the pattern is confirmed accurate. The exact number of days depends on style complexity and is confirmed per style when we talk.
-
Do your baby socks comply with national standards, and which safety class do they meet?
Quality standards
Baby socks strictly follow GB 18401-2010 and GB 31701-2015 and meet the Class A safety category: formaldehyde at or below 20 mg/kg and pH between 4.0 and 7.5. Children's and adult socks meet at least Class B. Lace, bows, ribbons and similar decorative attachments are individually pull-tested, no small parts of 3 mm or less are used, and no cords are placed at the head or neck of products for infants and children under seven.
-
Do you support dropshipping, and will popular sizes go out of stock?
Orders and delivery
Yes, dropshipping is supported. Kaixin holds core best-sellers in stock all year so online sellers can list products without holding inventory, reducing capital tied up and dead-stock risk. In-stock core styles ship quickly, and for long-term dropship partnerships the staple styles and stock levels can be agreed during style selection.
-
What is the lead time for volume orders?
Orders and delivery
Lead time depends on style complexity, order quantity and whether a new pattern must be developed. The standard approach is to schedule production by order volume once the sample is approved, with delivery dates agreed in writing when the order is confirmed. Annual capacity is 3 million pairs and routine monthly shipments are 400,000 pairs, so sustained volume is feasible. Incoming materials are sampled at no less than 5% and production is inspected every two hours so both schedule and quality stay under control.
-
What can be customized?
Customization and sampling
Customization covers five areas: style (patterns, motifs and colours combined freely), size (adjusted by foot length or age band across 0-12 years and adults), fabric (cotton content from 60% to 80% plus functional fibres such as antibacterial or mulberry silk), packaging (brand labels, hangtags and polybags aligned to your VI system) and function (anti-slip dot coating, antibacterial, moisture-wicking and thermal options).
