About Qingdao Huierde International Trade Co., Ltd - Chemicals & Allied Products Supplier in China

China, specifically the coastal city of Qingdao in Shandong province, lists five active products under its catalogue. The products are White aluminum oxide for electrolytic aluminum, Aluminum hydroxide for making aluminum oxide, High temperature calcined alumina, White fused alumina (WA) for abrasive and polish, and High temperature ceramic grade aluminum oxide. Each entry falls within the broader Chemicals & Allied Products category and is associated with HS Chapter 28 material families for aluminium compounds, although no specific HS codes are provided in the source data. The catalogue focuses on alumina derivatives used across metal production, refractory applications and abrasive industries. The supplier is classified as an imported tier with a harbor trust rating, indicating participation in cross‑border trade streams.

The listed alumina products serve distinct industrial functions: the white aluminum oxide is a feedstock for primary aluminium smelting, while aluminium hydroxide is an intermediate for producing synthetic alumina. High temperature calcined alumina and ceramic grade alumina are employed in refractory linings and high‑temperature processes, and white fused alumina is a common abrasive for polishing hard substrates. The five‑product set reflects a concentration on high‑purity oxide materials rather than a broader chemical portfolio. Buyers can therefore expect specifications centered on purity, particle size and thermal stability typical for these material classes.

Product Range and Specialties of Qingdao Huierde International Trade Co., Ltd

The catalogue includes five alumina‑based chemicals, each targeting a specific processing stage. White aluminum oxide for electrolytic aluminium typically meets purity grades of 99.5 % - 99.9 % with particle sizes from 0.5 to 5 µm, while the aluminium hydroxide precursor is supplied as a fine powder suitable for calcination to alumina. High temperature calcined alumina is usually graded at 99.6 %+ purity and designed to retain structural integrity above 1 800 °C, and the ceramic grade variant often exceeds 99.8 % purity with controlled grain growth for refractory use. White fused alumina (WA) for abrasive applications is commonly offered in grit sizes ranging from 0.1 mm to 1 mm, with Mohs hardness near 9.5. Industry standards such as ISO 9001 quality management and ASTM C792 for abrasive grading are typical references for these product types.

Trade and Export Information - Qingdao Huierde International Trade Co., Ltd

China ranks among the world’s largest exporters of alumina and related oxides, with shipments routinely directed to aluminium smelters in the Middle East, refractory manufacturers in Europe, and abrasive producers in North America and Southeast Asia. HS Chapter 28 (Aluminium and aluminium compounds) governs customs classification for all five products, and importers often require pre‑shipment inspection reports (e.g., SGS or Bureau Veritas) and compliance with REACH or local metal‑content regulations. Common logistics involve bulk bags of 1 tonne or 20‑ft containers for powdered forms, with Incoterms such as FOB Qingdao or CIF Shanghai frequently used. Buyers should verify that the supplier can provide material safety data sheets (MSDS) and that shipments meet the destination country’s quarantine and hazardous‑material handling rules.

Sourcing from Qingdao Huierde International Trade Co., Ltd - Buyer Guidance

When sourcing alumina products from this supplier, request a detailed specification sheet that lists purity percentage, moisture content, particle‑size distribution and thermal‑stability data. Buyers should also ask for an independent test report (ICP‑OES or XRF) and an MSDS to satisfy safety and customs requirements. Typical minimum order quantities range from 5 metric tonnes for bulk powder to a single 25 kg bag for sample evaluation, with lead times of 4 - 6 weeks after order confirmation. Verify that packaging meets moisture‑barrier standards and that the supplier can arrange container‑load consolidation if larger volumes are needed.

What alumina products does Qingdao Huierde International Trade Co., Ltd list in its catalogue?

The supplier lists five products: White aluminum oxide for electrolytic aluminium, Aluminium hydroxide for making aluminium oxide, High temperature calcined alumina, White fused alumina (WA) for abrasive and polish, and High temperature ceramic grade aluminium oxide.

What purity levels are typical for the white aluminum oxide offered?

White aluminum oxide for electrolytic use is generally supplied at 99.5 % - 99.9 % Al2O3 purity. Buyers should request a certificate of analysis to confirm the exact grade for each shipment.

Which certifications should a buyer request before purchasing these alumina products?

Buyers should request ISO 9001 quality‑management certification, an independent test report (e.g., SGS, Bureau Veritas), and a material safety data sheet (MSDS). Additional certifications such as REACH compliance may be required by European importers.

How are the alumina products typically packaged for export?

Bulk powdered forms are usually packed in 1‑tonne polypropylene bulk bags or in 20‑ft containers with inner liners to protect against moisture. White fused alumina for abrasive use may also be supplied in sealed drums or smaller bags for specialty orders.

What are common lead times and minimum order quantities for these chemicals?

Lead times are typically 4 to 6 weeks after order confirmation. Minimum order quantities are around 5 metric tonnes for bulk powder, while smaller sample quantities of 25 kg can be arranged for testing.

Which regions most frequently import high temperature ceramic grade aluminium oxide?

Major importers include refractory manufacturers in the Middle East, steel‑making facilities in Europe, and high‑temperature furnace producers in North America. These regions value the material’s high thermal stability and purity.

What documentation is needed for customs clearance of alumina products?

Customs authorities usually require a commercial invoice, packing list, certificate of origin, MSDS, and a test report confirming purity and composition. Depending on the destination, a REACH or equivalent environmental compliance declaration may also be required.

How can a buyer verify product quality before shipment?

Buyers can request pre‑shipment samples and a third‑party analysis report covering purity, moisture and particle‑size distribution. Upon receipt, visual inspection for moisture damage and verification of the accompanying certificates complete the quality‑check process.
