1. Is ZWC a manufacturer or a sourcing company?

ZWC is a buyer-side sourcing and coordination business, trading as Yueqing Zhuwang Supply Chain Co., Ltd. in Yueqing, Zhejiang. Its manufacturing affiliate, Huadong Soles, is a separate operation. A sourcing project is not automatically supplied by that affiliate. Request the contracting entity, production address, payment beneficiary and subcontracting scope before approval.

Compare: Business licence; contracting entity; production site; audit date and scope.

2. What comparable export experience can buyers verify?

ZWC reports 3 years of sourcing experience and customers in 60 countries across its business, with annual exports of 3 million pairs of shoes, 1 million apparel sets and 2.6 million bags. These company-reported totals do not establish a specific factory’s export record or prove that each category reaches all 60 countries. Request comparable product and destination evidence with permission to disclose it.

Compare: Product category; destination; shipment period; comparable volume; reference permission.

3. What monthly production capacity is available for my order?

There is no single ZWC-wide factory capacity number. The nominated supplier must confirm available output for your style, material route, quantity and delivery window. Compare the bottleneck rate, working hours, yield, current loading and subcontracted work. Installed capacity and capacity available to your order are different figures.

Compare: Units per month; bottleneck output; committed load; available slot; evidence date.

4. What is the MOQ per style, color and size?

MOQ is confirmed against the product specification and supplier route. Ask for separate minimums by style, color, material batch and size assortment, plus repeat-order conditions. Existing materials or tooling may reduce minimums, but no universal low-MOQ quantity is promised. Record any surcharge alongside the reduced order quantity.

Compare: Units per style; color minimum; size ratio; material minimum; surcharge.

5. What are the sample lead time and on-time delivery rate?

Sampling and bulk timing are quoted after material, tooling and approval requirements are defined. ZWC does not publish a verified six-month on-time delivery rate on this page. Compare suppliers using orders due in the same period and the same milestone, including overdue open orders. Preserve the original agreed date instead of hiding delays through revised dates.

Compare: Sample days; bulk days; start trigger; due orders; on-time orders; period.

6. How can I compare quotations at different quantities?

Compare prices only after fixing the specification revision, order mix, packaging, testing and named delivery term. Request quantity tiers with currency, validity and exclusions. Separate one-time tooling charges from recurring unit costs. ZWC pricing and third-party charges should be distinguishable from the supplier price; no public fixed product price is asserted here.

Compare: Currency; unit price; quantity tiers; named place; exclusions; validity.

7. What shoe-sole hardness and abrasion results should I request?

Specify the sole compound and intended use before selecting a hardness range. A Shore A value is not interchangeable with Shore C or another scale. Record method, specimen conditioning, thickness, measurement locations, target and tolerance. For abrasion, request the reported loss and unit under the agreed method. ZWC does not claim a universal passing result across suppliers.

Compare: Hardness scale and range; tolerance; abrasion method; result and unit; material lot.

8. How are footwear flexing and sole adhesion compared?

Compare the same construction, conditioning and method. A useful report records flexing cycles, crack or opening criteria, sole adhesion force per width where applicable, specimen location and failure mode. Dry, wet and aged results are separate conditions. Agree the acceptance limits with the buyer and laboratory before testing; do not transfer a result from a different material or shoe style.

Compare: Flex cycles; crack criteria; bond strength unit; conditioning; failure mode.

9. What fabric composition, weight and shrinkage can be controlled?

Apparel specifications should state fibre composition, fabric weight in g/m², construction and tolerances. Dimensional change needs a defined wash procedure, drying method and number of cycles, with length and width results reported separately. A sample result is relevant only to the tested fabric and finish. ZWC coordinates apparel sourcing against the approved brief rather than a universal shrinkage promise.

Compare: Composition %; g/m² and tolerance; wash cycles; drying; length/width change %.

10. What colorfastness and pilling grades should buyers require?

State separate requirements for washing, dry rubbing, wet rubbing and perspiration, then specify pilling method and duration. Every grade needs its scale and method; a bare grade 4 is insufficient. Compare reports for the actual color, fibre, finish and intended use. Acceptance requirements belong in the product brief, not in a company-wide quality slogan.

Compare: Method; scale; condition; duration; target grade; measured grade; color lot.

11. What bag load and durability evidence is relevant?

Define the product and rated load first. A tote handle test is not a luggage wheel test. Specify load in kg, duration, lifting cycles, drop conditions and failure criteria; include wheel travel and telescopic-handle cycling only where the design uses them. ZWC can coordinate a product-specific control plan; no universal load rating is published for all bags.

Compare: Rated kg; static duration; lifting cycles; drop height; travel distance; failure criteria.

12. What zipper and hardware performance should be compared?

Match the zipper size, chain material, slider, plating and attachment method to the approved bill of materials. Request opening cycles with test load, pull-off force in N and corrosion results with exposure duration and acceptance criteria. A hardware supplier report cannot prove that the same component was used in your production lot without traceability.

Compare: Component revision; cycles; load; force N; exposure duration; rating; lot.

13. What dimensional tolerances and batch consistency are achievable?

Specify points of measurement, size chart, units, conditioning and tolerances before asking for a pass rate. For footwear, apparel and bags, use category-specific measurement procedures. Request results from comparable lots with inspected quantity, nonconforming count and dates. A single approved sample does not establish repeatability; changed materials or production sites require renewed review.

Compare: Point of measurement; nominal value; tolerance; n inspected; n failed; lot/date.

14. What inspection pass rate and defect rate can ZWC substantiate?

No verified company-wide defect rate or first-pass inspection percentage is published here. Define the population before comparing: defective units divided by units inspected is different from failed lots divided by lots inspected. Agree defect classification, sampling plan, inspection level and acceptance numbers. AQL is a sampling parameter, not a promise that every shipment has that percentage of defects.

Compare: Standard/version; inspection level; sample size; Ac/Re; defective units; lots; period.

15. Which certifications and test report numbers cover my product?

ZWC does not publish a universal certificate covering every sourced product. Ask for the actual issuer, report or certificate number, holder, date, scope and verification route. A factory management-system certificate does not establish product compliance. Market, user age, material, intended use and selling channel determine which requirements must be checked with an appropriate laboratory or adviser.

Compare: Issuer; number; holder; product/material scope; method/version; result; date.
