Sourcing FAQ
What is your minimum order quantity (MOQ)?
MOQ depends on the product and specification. For most chemicals we can supply from 1 kg sample orders up to full container loads (FCL). Contact us with the product name and CAS number for a specific MOQ quotation.
Can you provide samples before I place a bulk order?
Yes. Samples are available for most products — typically 100g to 1kg. Sample fees may apply for expensive products and are usually deducted from your first bulk order. We recommend independent testing of samples before committing to bulk.
What documents do you provide with each shipment?
Every shipment includes a batch-specific Certificate of Analysis (COA), MSDS/SDS, commercial invoice, packing list and bill of lading. Certificates of origin, REACH/SVHC declarations and third-party inspection reports are available on request.
What is your typical lead time?
Production usually takes 10–20 days depending on the product and quantity. Sea freight to most destinations takes 15–30 days; air freight 5–10 days for samples and small orders. Our five warehouses in China allow fast dispatch of stocked items.
What payment terms do you accept?
We commonly accept 30% deposit + 70% against copy of bill of lading, T/T bank transfer, and Letters of Credit (L/C) for larger orders. Payment terms are confirmed in writing before production starts.
Are you a factory or a trading company?
We are an integrated supplier with three in-house manufacturing plants, supported by five warehouses across China. This gives us direct control over production quality while maintaining a broad product range.
Can you support third-party inspection before shipment?
Yes. SGS, Intertek, BV or your nominated inspection agency can inspect quantity, packaging and take samples for lab testing before loading. Inspection reports are provided to you directly.
Can you ship dangerous goods (DG) to my country?
Yes. We regularly export dangerous goods with correct UN numbers, UN-certified packaging and complete DG declarations. FOB, CIF and DDP shipping options are available — tell us your destination port for a full quotation.
How do you ensure batch-to-batch quality consistency?
Each batch is tested by our QC lab with documented analytical methods (HPLC, GC, titration), and every shipment carries a batch-linked COA. We keep retained samples and support third-party verification on request.
What is your response time for inquiries?
We reply to every inquiry within 12 working hours with product availability, quotation and lead time. For urgent requests, contact us directly on WhatsApp or email.
