All our products comply with international export standards (such as SEMI, GB, FDA, and EU 1935/2004), and we offer a complete range of standard specifications. We can customize key parameters such as product concentration, purity, and impurity content based on customers' specific needs to meet the requirements of various application scenarios.

2. How is product quality ensured? Do you provide relevant test reports?

We operate standardized production facilities with meticulous control throughout the entire process. Every batch undergoes rigorous testing before shipment. We can provide third-party test reports (e.g., SGS, Intertek), TDS (Technical Data Sheets), and SDS (Safety Data Sheets) to ensure product quality meets standards and complies with export regulations.

3. Are product samples available? What are the sample fees and shipping methods?

Free samples are available (standard specifications, limited quantities). Shipping costs for samples are negotiable. Shipping methods are selected based on product characteristics (standard courier or air freight). Hazardous chemical samples will be packaged strictly in accordance with international transport regulations to ensure safety and compliance, with delivery times adjusted based on the destination.

4. What packaging specifications are available for the products? Do they meet export standards?

We offer a comprehensive range of packaging specifications. For reagent-grade and electronic-grade products, the smallest units are milliliter (mL) or milligram (mg) bottles or pouches. Industrial-grade options include 25kg/50kg paper-plastic composite bags (with PE lining), 1,000L IBC containers, and 20-ton tanks; All packaging complies with international hazardous materials transport standards (UN-certified), featuring moisture-proof, leak-proof, and crush-resistant properties.

6. How does the packaging of hazardous chemicals ensure transportation safety?

All hazardous chemical packaging features a double-layer protective structure (e.g., outer paper-plastic composite bag + PE inner liner) and is designed in strict accordance with UN hazardous materials transport requirements. It is labeled with standard GHS pictograms, UN transport symbols, and storage/handling instructions (Handle with Care, Keep Dry, This Side Up, etc.).

7. What is the minimum order quantity (MOQ) for products? Are there discounts for bulk purchases?

The MOQ for standard products is flexible; we accept both small-batch samples and large-volume orders. Bulk purchases (reaching agreed-upon volumes) qualify for tiered discounts, with specific terms determined through negotiation based on product category and purchase volume.

8. What are the pricing terms? What payment methods are available?

Quotations are primarily based on standard international trade terms such as FOB and CIF, with specific prices calculated based on product specifications, purchase volume, and destination. Accepted payment methods include T/T (wire transfer) and L/C (letter of credit), among others. These terms may be adjusted through mutual agreement based on the nature of the partnership to safeguard the interests of both parties.

9. What is the delivery lead time?

For standard-specification products, in-stock orders are shipped within 3-5 business days. For custom-specification products, delivery times are calculated based on the production cycle (7-15 business days) and logistics transit times; specific delivery dates can be negotiated to ensure on-time delivery.

10. Does your company possess the necessary qualifications for exporting chemical products? To which countries and regions can you export?

We handle all customs clearance and inspection procedures throughout the process.

11. How are logistics methods selected? How are freight charges calculated?

Depending on product characteristics (general chemicals/hazardous chemicals), destination, and customer requirements, we select logistics methods such as sea freight, air freight, or international express. Freight charges are calculated based on cargo weight, volume, destination, and logistics method. We provide end-to-end logistics tracking services to ensure safe delivery of goods.

12. Does your company provide the documents required for export customs clearance?

Yes, we will assist customers throughout the entire export customs clearance process and provide the full set of required documents (such as commercial invoices, packing lists, customs declarations, SDS, TDS, hazardous chemical transport certificates, etc.) to ensure a smooth and compliant clearance process.

13. How are quality issues handled after receiving the products?

If a customer discovers that the product quality does not meet the agreed-upon standards after receiving the goods, they must provide relevant evidence (such as test reports or photos of the goods) within 7 business days of receipt. We will verify the issue immediately and provide solutions such as returns, exchanges, or compensation based on the actual situation to protect the customer's rights and interests.

Can ultrapure water be stored for long time?

Not recommended. It absorbs CO2 from air and resistivity drops quickly. Use promptly after receiving.

Can water specification be customized?

Yes, TOC, endotoxin and other parameters can be adjusted upon request.
