Before you commit to bulk production, see exactly who is making your shoes and bags. Real workshops, a dedicated 20-person quality team, and documented visits from designers and brands worldwide — this is how we earn the right to your first order.
Herrains operates inside the XINZIRAIN Group's own 8,000㎡ facility, established in 1998, with in-house design, sampling, cutting, stitching and packaging. Explore the workshops below, then arrange a visit to review the processes relevant to your collection.

Our 20-person QC team reviews materials, construction, finished products and packaging. Footwear follows seven checkpoints across the four stages below; bag projects use an agreed checklist for materials, stitching, hardware, closures and finishing.
Review leather, textiles, soles and hardware against the agreed specifications. For bags, include lining, trims, color consistency and visible surface defects.
Check cut pieces and heel attachment for footwear. For bags, agree checks for panel dimensions, handle and strap attachment, and reinforcement at stress points.
Review upper stitching, sole attachment and finishing on footwear. Include seam quality, edge finishing, lining, zippers and hardware operation in the bag checklist.
Compare finished items with the approved sample and agreed criteria. Confirm branding, labels, quantities, protective packing and carton details before shipment.
The 100% pre-shipment inspection commitment covers each finished item against agreed visual, workmanship and packaging criteria. Fit, wear, durability and laboratory tests have separate sampling requirements; agree their scope and methods before production.
Before placing the order, confirm defect criteria, how flagged items will be corrected and reinspected, and the records required for shipment approval. Use the approved physical sample and written specifications as the shared reference.
Inspection results are only as reliable as the team behind them. Our Quality Control Director oversees a 20-person team dedicated exclusively to inspection — independent from the production line — and reports directly on every batch before it is released for shipment.
Ashley leads our quality assurance system, running rigorous inspections at every production stage — from incoming materials to the final packed carton — to protect brand reputation with every shipment.
Levi's team turns approved designs into manufacturing reality, defining construction methods and material standards that our QC department inspects against.
Explore recent client visit reports and the types of factory and sample reviews available for your own project. Review the workshops, sample rooms and QC process before your first production order.
A two-day, on-site review covering sample plan discussion, material selection, craftsmanship, and delivery stability — the same four checkpoints every international brand should verify before production.

Brand owners from Canada, the U.S. and Europe have toured our workshops, sample rooms and design department in person — reviewing materials and craftsmanship before confirming samples for production.
Browse client case studies →Use your factory review to discuss sample development, material selection and production capability. Bring a project brief or reference sample so the discussion focuses on construction, approval steps and your first production order.
Explore our development process →A factory review should also cover your design files, material documentation and approval process. Agree the scope and supporting records for your project before development and production begin.
Request an NDA before sharing confidential sketches, Tech Packs or unreleased collection details. Define who may access the files, how they may be used and which project deliverables belong to your brand.
The signed agreement, file-use permissions, ownership terms and any approval required before project images are published.
For EU-bound collections, discuss applicable REACH restrictions for your chosen leather, textiles, coatings and hardware. Confirm which supplier declarations and test reports are available and whether further testing is needed.
Material and component coverage, report dates and testing scope. Agree the laboratory, cost and timing for any additional tests.
For suitable footwear projects, CAD and 3D prototypes help review shape, proportions and selected components. Confirm the approach and deliverables for your design, then review physical samples for fit, feel and construction.
Agreed digital deliverables, sample revisions, the approved physical sample and the specification sheet used for bulk production.
Include working conditions, material use and waste handling in your factory review. Read our sustainability commitments and discuss the practices relevant to your collection with the team.

Yes. International designers and brand owners are welcome to visit our Chengdu facility by appointment. Review the production workshop, sample room and quality-control process with our team, and bring your questions about materials, construction and order requirements. Share your product category and development stage in advance so the visit focuses on your project.
We support live video factory tours and photo or video updates at agreed production checkpoints. You can review the workshop, discuss samples and examine key details remotely. Tell us which materials, workmanship details and inspection records you want to see before the call, so our team can prepare a focused review.
NDA protection is available before you share confidential sketches, Tech Packs or unreleased collection details. Agree in writing on permitted use, access and onward disclosure, together with ownership and delivery of project-specific CAD files and patterns. Any exclusivity or permission to publish project images should also be expressly covered in the agreement before development begins.
We support material selection for EU-bound collections, with review against applicable REACH restrictions. Ask for available supplier declarations and test reports relevant to your leather, textiles, coatings and hardware. Agree any additional testing, laboratory, costs and timing before production. Report coverage must match the selected materials and components; it does not automatically cover every product or future order.
For suitable footwear projects, CAD and 3D modeling or printed prototypes help review shape, proportions and selected components before physical sampling. Our team confirms which approach fits your design and agrees the scope, cost and deliverables first. Fit, comfort, material feel and construction still need approval through physical samples. Explore our sample development process.
The approved physical sample and agreed specification sheet provide the reference for bulk production. Confirm materials, colors, dimensions, branding and construction details, and record revisions and acceptance criteria in writing. This gives production and QC a shared reference. Any later changes to materials or construction should be reviewed and approved before they are used in your order.
Our dedicated 20-person QC team checks materials, construction, finished products and packaging. For footwear, the seven checkpoints cover material selection, cutting, heel stability, upper construction, bottom construction, finished products and packaging. For bag projects, agree checks for stitching, hardware, closures and other design-specific details before production. Confirm the criteria for checks on every finished item and the sampling requirements for performance or laboratory tests in your inspection plan.
Batch-level QC records and photo or video updates can be prepared as part of your agreed production package. Confirm the reporting format, checkpoints and any buyer-specific requirements before placing the order. Internal factory QC records and independent laboratory test reports serve different purposes; request the documents relevant to your buyer's checks and confirm their availability.
