How do I contact the Sirenstrum sales team?

Use the Contact page form or message us on WhatsApp at +86 177 2151 9382. Include your style numbers, target quantity, size run, and destination country so we can quote accurately.

How do I place a wholesale order?

Send an inquiry with the styles you want, quantity per style, size run, colour direction, and destination country. We confirm the specification and issue a written quotation before production is scheduled.

How are samples and quality claims handled?

Sample routes, cost, and timing are confirmed in writing before production. Any shortage, damage, or specification concern should be raised in writing with photos within the inspection window agreed on your order, before goods are washed, altered, or sold on.

Placing an Order

Shortlist the styles you want, then send the product names or page links with quantity per style, size run, colour direction, packing requirements, and destination country. We confirm the specification and issue a written quotation — production is scheduled only after that quotation is approved and paid.

Payment

Sirenstrum does not operate a public checkout. Your quotation states the unit pricing, MOQ, packing, lead time, shipping terms, and the payment details for that order. We will not ask you to pay into different account details mid-order.

Delivery

Delivery options depend on the destination country, order volume, and selected styles. We confirm the shipping route, estimated timing, packing specification, and which party handles duties and customs clearance before your order is finalised.

Quality Claims

This is a business-to-business supply relationship, so claims are assessed against the approved sample and written specification. Please inspect goods on arrival and raise any shortage, damage, or specification concern in writing with photos before goods are washed, altered, relabelled, or sold on.

Size Guide

Use the size guide as a starting point for the size run you want to buy. Fabric, cup shape, straps, and construction can shift how a style fits, so we confirm the size range and measurement basis you need before production.

Product Availability

Fabric, colour, and component availability can change between seasons. Send the styles and quantities you are interested in so we can confirm what is available, what can be repeated, and what would need a material substitution.

Business Enquiries

For wholesale, private label, custom packaging, sample programs, agency, or partnership enquiries, send your details through the Contact page or request a quote so it reaches the right person with the information needed to respond.
