FAQ

MOQ, sampling, quality standards and delivery

Common questions about Kaixin Socks: OEM MOQ 5,000 pairs and custom styles from 2,000 sets, sampling and dropshipping supported, baby socks meeting GB 31701-2015 Class A with a batch inspection report, and production aligned with OEKO-TEX® Standard 100, REACH and CPSIA.

Orders and delivery

  • Is there a minimum order quantity for a first order, and how large is it?

    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.

  • Do you support dropshipping, and will popular sizes go out of stock?

    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?

    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.

  • Can we place a small trial order first?

    Yes. Kaixin supports low-MOQ light customization and small in-stock purchases, which suits startup brands and smaller merchants validating market response. A trial order can adjust colour, lace trim or packaging on an existing fit, and once it succeeds the same process standards carry straight into volume production.

Customization and sampling

  • Can you produce a sample, and how long does sampling take?

    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.

  • What can be customized?

    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).

  • I do not have a ready style — can you develop one for me?

    Yes. Kaixin has in-house ODM capability, with designers, process engineers and pattern specialists who follow market trends and the wearing needs of babies and children and can independently take a new style from concept through pattern design, fit revision and process implementation. The usual approach is for us to suggest styles or revisions based on your positioning, then move to sampling and volume production once the direction is agreed.

Quality standards

  • Do your baby socks comply with national standards, and which safety class do they meet?

    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.

  • Can you provide a quality inspection report?

    Yes. A quality inspection report is available for every batch, so quality can be traced. The company runs an item-level traceability system with unique codes, and finished goods complete 11 internal quality tests plus a full visual inspection before dispatch, targeting a 100% outbound pass rate.

  • Can your products be exported, and which international standards can you meet?

    Yes, export orders are accepted and produced to export standards. The quality system can align with OEKO-TEX® Standard 100 (suitable for Class II products in direct skin contact, covering more than 1,000 harmful substances), the EU REACH regulation and US CPSIA testing requirements. Export packaging and labelling can be adjusted to destination-market requirements.

  • Will patterns stay consistent across a batch?

    Yes. Kaixin runs WHL2_A8 fully automatic circular knitting machines with pattern import and jacquard needle-selection functions that reproduce complex motifs accurately. Before a patterned style runs, the pattern file is imported and needle selection verified; volume production only starts once the pattern is confirmed free of misalignment and dropped stitches, so shape, colour and texture stay consistent across the batch.

Cooperation and payment

  • Can we visit the factory for an audit first?

    Factory audits are welcome. The plant is at Room 202, Building 2, No. B99 Huancheng North Road, Houzhai Street, Yiwu, Jinhua, Zhejiang, and includes a raw material store, knitting workshop, toe-closing workshop, finishing workshop, finished-goods inspection area and finished-goods warehouse. You can see the 60 fully automatic knitting machines running and review inspection records on site. Please book through the online form in advance so we can assign a contact person.

  • How do payment and invoicing work?

    VAT invoices are available with a 2% invoicing point. The exact payment method and milestones are agreed before cooperation based on order value, delivery batches and customer type, and written into the agreement. It helps to mention your preferred settlement terms in the online inquiry so we can include a proposal with our quotation.

  • Besides volume manufacturing, what other ways can we work together?

    Kaixin supports several models: OEM labelling, ODM development, sample-based customization, rapid sampling, low-MOQ light customization, stock supply and dropshipping, and bulk wholesale with long-term manufacturing. Whether you are a startup brand still choosing styles or a wholesaler needing stable long-term supply, describe your needs on the contact page and we will propose a suitable model.

  • How do I contact Kaixin Socks, and how quickly will I hear back?

    You can submit your requirements through the online inquiry form on the contact page, or call +86 183 6866 1602 (also the WeChat number) to reach Mr. Wang. We reply within one business day with pricing and a sampling plan. To speed things up, please include reference styles, size ranges, expected quantity and your target delivery date in the inquiry. You can also reach us through our official 1688 store.

Products and styles

  • What is the cotton content, and is it suitable for babies?

    The core range is knitted socks made from quality yarns with 60%-80% cotton plus spandex-covered yarn. Baby socks use a high-cotton, soft and skin-friendly fabric with a seamless toe and relaxed rib cuff to reduce friction and pressure marks, making them suitable for next-to-skin wear by infants. If you need higher cotton content or a different fibre ratio, it can be configured during fabric customization.

  • How are sizes divided, and which age groups are covered?

    Products cover 0-12 years and adults, segmented by foot length or age band. Main series include baby socks (0-3), kids socks (3-12), princess socks (3-12), non-slip and floor socks (babies and toddlers), mulberry silk socks (kids and adults) and sports socks (kids and adults). If you need different segmentation or intermediate sizes, this can be adjusted during size customization.

Materials

  • What materials are socks commonly made of, and what are their characteristics?

    Common materials include combed cotton, regular cotton, bamboo fiber, modal, lyocell, polyester, nylon, spandex, wool, cashmere and blends. Cotton absorbs sweat, breathes well and feels skin-friendly; bamboo fiber is antibacterial, odour-resistant and soft; modal feels smooth; polyester is hard-wearing and quick-drying; nylon offers good elasticity and strength; spandex provides high stretch; wool is warm; blends balance cost and performance.

  • How do I choose sock material according to how it will be used?

    For everyday wear choose a high cotton content with a little spandex; for sports socks a polyester, nylon and spandex blend emphasises moisture management; business socks work well in combed cotton or modal; children's socks should prioritise soft, safe, non-irritating materials; for winter warmth choose wool or a thicker blend.

  • Does material affect price and safety?

    Yes. Cotton content, yarn count, weight, functional yarns and certification level all affect the price. On safety, check formaldehyde, pH value, decomposable aromatic amine dyes, colour fastness, odour and fibre content against the applicable standard.

  • How can I avoid misstated material content?

    Ask the supplier for a fibre composition test report together with weight and yarn count, confirm against an approved sample, and spot-check the bulk goods. For custom orders, write the material, composition ratio and weight into the contract.

Production

  • What does the sock production process usually involve?

    It typically covers yarn intake, knitting, toe linking, turning, boarding (heat setting), quality inspection and packing. Custom socks add sampling, sample approval, jacquard, printing or embroidery, plus hangtag and packaging steps.

  • How long is the production lead time for socks?

    In-stock goods usually ship in 1-3 days; custom sampling takes about 5-10 days; bulk production about 15-30 days; peak season or complex craftsmanship can take 30-45 days. The exact time depends on quantity, material, technique and the factory schedule.

  • Is sample-based processing and private-label production supported?

    Yes. Sample-based processing, OEM, ODM and private label are all common. The customer provides a sample, artwork, logo and packaging requirements, and the factory produces to the approved sample.

Safety and certification

  • Which safety indicators matter for socks?

    Formaldehyde content, pH value, decomposable carcinogenic aromatic amine dyes, colour fastness to water and perspiration, odour, fibre content, and drawstring safety on children's products.

  • What safety certifications are common for socks?

    Commonly OEKO-TEX Standard 100, BSCI, ISO 9001, REACH, CPSIA and AZO Free. When exporting to the EU, the United States, Japan or other markets, confirm the requirements of the destination regulations.

  • How do safety requirements differ between children's socks and medical socks?

    Children's socks focus on soft materials, no detachable small parts, drawstring safety, colour fastness and chemical residues; medical or compression socks focus on compression grade, size fit, skin-friendly material and compliance with the relevant medical device regulations.

Uses and selection

  • Which socks are recommended for different uses?

    Everyday socks prioritise comfort and breathability; sports socks prioritise cushioning, sweat absorption and grip; business socks prioritise a thin, formal, hard-wearing build; children's socks prioritise safety and softness; maternity and elderly socks prioritise a loose fit and anti-slip; medical socks prioritise compression and sizing; gift socks prioritise packaging and design.

  • Can functional socks be customised?

    Yes. Common functions include antibacterial, odour-resistant, moisture-wicking, thermal, compression, anti-slip, cushioned, breathable and quick-dry. Confirm how the function is achieved, the test standard and the cost.

Small batches and dropshipping

  • Is single-piece wholesale or dropshipping supported?

    Single-piece minimum orders, one-piece dropshipping or small mixed batches are usually available, but the unit price is higher than bulk pricing, and some suppliers charge a dropshipping service fee, packaging fee or freight.

  • Can a single-piece order be mixed in colours and sizes?

    Yes, subject to stock. The usual arrangement is random mixed colours and sizes; specified colours and sizes are also possible, normally at a surcharge or from a certain quantity.

  • How long does a single-piece order take to dispatch?

    In-stock items usually ship within 24-72 hours; when order volume is high or picking and packing are required, about 3-5 days. Overseas dropshipping adds international transit time on top.

Dispatch lead time

  • How long does in-stock dispatch normally take?

    Domestic in-stock orders usually ship in 1-3 days, or 3-7 days during peak season and major promotions. The exact time depends on stock and courier pickup.

  • What is the dispatch time for bulk and custom orders?

    Bulk orders normally take 15-30 days; custom orders require 5-10 days for sampling first, then 15-30 days for bulk production. Peak season, complex craftsmanship or raw material shortages extend these times.

  • What are the main factors affecting dispatch time?

    Stock levels, raw materials, factory scheduling, order quantity, process complexity, quality inspection, packaging, payment timing, public holidays and peak-season logistics pressure.

  • What should be confirmed before placing an order?

    Confirm each item: material composition, weight, yarn count and stretch ratio; safety certification, test reports and destination regulations; use, function, size, colour and packaging; single-piece wholesale, dropshipping and mixed-batch rules; in-stock or bulk dispatch lead time; overseas shipping method, freight, duties and declared value; customization scope, sampling fee, sampling time and bulk lead time; pre-order deposit, balance and amendment rules; overseas delivery time, customs responsibility and after-sales claims; payment method, quality standard, inspection method and after-sales terms.

Overseas shipping

  • What overseas shipping options are available?

    International express, dedicated international lines, postal small packets, air freight, sea freight and overseas warehouse fulfilment. For small urgent shipments choose express or a dedicated line; for bulk choose air or sea freight; for fast local fulfilment choose an overseas warehouse.

  • How are overseas freight and duties calculated?

    Freight is calculated by weight, volume, destination and channel. Duties, VAT and customs clearance fees are normally borne by the shipper or the consignee according to the trade terms, so confirm DDP or DDU in advance.

  • What information is required for overseas shipping?

    Usually the consignee's name, phone, address, postcode and country, plus product name, material, quantity, declared value and HS code. Some countries also require a tax number, import licence or certification documents.

Customization process

  • What can be customised on socks?

    Material, colour, size, weight, logo, jacquard, embroidery, printing, woven label, hangtag, packaging, function and compression grade, among others.

  • What is the sock customization process?

    Requirement discussion, quotation, sampling, sample approval, deposit, bulk production, quality inspection, balance payment and dispatch. Cross-border orders also require export clearance, certification and a logistics plan to be confirmed.

  • What are the sampling cost and lead time for custom orders?

    Sampling normally takes 5-10 days, and the cost depends on technique and material. Some suppliers refund the sampling fee once the bulk order reaches a certain quantity, so confirm this in advance.

Overseas pre-order

  • What is an overseas pre-order?

    An overseas pre-order means a customer places an order in advance and pays a deposit so that production or stocking can be arranged, then pays the balance before the goods are shipped overseas. It also suits independent-site pre-sales, marketplace pre-sales and seasonal buying.

  • What does the overseas pre-order process look like?

    Select or customise styles, confirm specifications and quantity, receive a quotation, pay the deposit, produce or stock the goods, inspect them, pay the balance, ship overseas and take delivery.

  • Can an overseas pre-order be amended after it is placed?

    Generally yes before sampling or production starts; once sampling is done or production has begun, changes are difficult. Discuss colour, size, packaging and quantity changes as early as possible and confirm whether any cost applies.

Overseas delivery and receipt

  • How long does overseas delivery usually take?

    For reference: overseas warehouse 1-3 days; international express 3-7 days; dedicated international line 7-15 days; air freight about 7-15 days; sea freight 20-40 days. Add 1-3 days for customs clearance, and longer in peak season.

  • What factors affect overseas delivery time?

    The shipping method, destination country, customs clearance efficiency, peak season, weather, port congestion, policy changes, remote areas and how responsive the consignee is.

  • How do I track the shipment and its customs clearance?

    Once the supplier or freight forwarder provides a tracking number, you can track it on the courier website, the line operator system or the forwarder platform. If clearance is held up, the consignee needs to supply a tax number or ID details, or pay the duties.

  • How should delivery problems be handled?

    First photograph and keep the packaging, waybill and goods, then contact the carrier and the supplier. Whether compensation applies depends on insurance, whether the issue is customs-related, and whether the goods were lost or damaged, in line with the claim terms.
