About Henan Sigma Aluminum Industry Co., Ltd - Agriculture Supplier in China

Henan Sigma Aluminum Industry Co., Ltd operates in Henan province, China and lists nine distinct aluminium products in its catalogue. The portfolio includes various alloy circle plates such as 3003 and 6061, as well as specialised forms for crafts and electronic packaging. In addition, the company offers several foil grades, including 8011 cable foil, 8021 pharmaceutical packaging foil, and a general household aluminium foil. All items appear under the agriculture top‑category in the source data, reflecting possible applications in agricultural equipment and packaging. The product titles are given by alloy numbers and intended end‑use rather than by any brand name.

The aluminium circle items are described as “Alloy 3003” or “6061” circles, which are standard commercial alloys used for forming and stamping. Foil entries are identified by their HS‑related designations such as 8011 and 8021, indicating cable and pharmaceutical packaging grades respectively. The catalogue does not provide dimensional data, but the naming follows industry conventions for thickness and width specifications. No additional company history, capacity or client information is supplied in the source facts. The nine products together represent the full active listing for this supplier.

Product Range and Specialties of Henan Sigma Aluminum Industry Co., Ltd

The listed catalogue covers two main formats: round aluminium plates and aluminium foil sheets. Circle products include standard 3003 alloy, which typically offers good formability and corrosion resistance, and 6061 alloy, known for higher strength after heat treatment. Foil entries comprise 8011 cable foil, commonly supplied in thicknesses from 5 µm to 30 µm for electrical insulation, 8021 foil for pharmaceutical packaging that usually meets USP <USP‑NF> requirements, and a household foil variant often sold in rolls of 10‑30 µm thickness. Industry practice for these alloys includes tolerance of ±0.02 mm for plate diameter and surface roughness Ra ≤ 0.8 µm for foil, with purity levels above 99.5 % aluminium.

Typical specifications for the 3003 and 6061 circles follow ASTM B221 for extruded aluminium shapes, while foil grades align with ASTM B209 for aluminium sheet and foil. Buyers commonly request material test reports that include tensile strength, elongation, and alloy composition. The catalogue does not specify packaging, but standard trade practice ships plates in wooden crates and foils in insulated cardboard rolls.

Trade and Export Information - Henan Sigma Aluminum Industry Co., Ltd

China is a major exporter of aluminium semi‑finished products, and shipments of alloy circles and foils are regularly routed to Southeast Asian manufacturers, European food‑packaging firms, and North American electronics assemblers. The HS chapters that usually cover these goods are 7610 (aluminium plates, sheets and foil) and 7612 (aluminium foil and strip), although no HS codes are attached to the supplier’s listing. Importers typically require compliance with ISO 9001 quality management and, for pharmaceutical foil, ISO 13485 or GMP documentation. Additional certifications such as ASTM B209, ASTM B221, and food‑contact compliance (e.g., FDA 21 CFR 176) are frequently requested by buyers in the United States and EU.

Logistics for aluminium products from China often use 20‑ft or 40‑ft containers, with the foil rolls packed in moisture‑resistant bags and the circular plates secured in wooden pallets. Common Incoterms include FOB Shanghai or CIF Europe, depending on the buyer’s preference. Export licensing for aluminium is straightforward, but customs authorities may request material certificates and test reports to verify conformity with the declared HS code and specifications.

Sourcing from Henan Sigma Aluminum Industry Co., Ltd - Buyer Guidance

When sourcing from this supplier, buyers should request a mill test certificate that confirms alloy designation, mechanical properties and chemical composition for each circle plate. For foil products, a certificate of analysis should include thickness uniformity, tensile strength, elongation, and any relevant food‑contact or pharmaceutical compliance statements. Samples of the foil in rolled form and a small batch of the circle plates are advisable to verify dimensional tolerances and surface finish before placing a larger order.

Typical minimum order quantities in the aluminium industry range from 500 kg for specialty foil rolls to 1 tonne for standard alloy circles, but the exact MOQ should be confirmed with the supplier. Lead times for aluminium extrusion and foil slitting in China usually run 30‑45 days from order confirmation, subject to furnace capacity and current export volumes. Buyers are encouraged to verify that the supplier can provide the required certifications and test reports prior to shipment, and to specify packaging requirements such as anti‑corrosion coating for plates or vacuum‑sealed bags for foil.

What alloy grades are available for the circular aluminium plates?

The catalogue lists 3003 alloy circles, which are commonly used for high formability, and 6061 alloy circles, which provide higher strength after heat treatment. Both grades conform to ASTM B221 specifications for extruded aluminium shapes.

Are there specific foil thicknesses offered for the 8011 cable foil?

While the supplier does not state exact thicknesses, 8011 cable foil is typically supplied in the 5 µm to 30 µm range for electrical insulation. Buyers should request a thickness data sheet to confirm the exact grade.

What documentation should I request for the 8021 pharmaceutical packaging foil?

Request a certificate of analysis that includes purity, thickness, tensile strength, and compliance with USP <USP‑NF> or FDA food‑contact regulations. A GMP or ISO 13485 statement is also commonly required for pharmaceutical applications.

Is a mill test certificate available for the aluminium circles?

Yes, a mill test certificate confirming alloy composition, tensile strength, elongation and any heat‑treatment condition should be provided for each circle plate batch.

What are the typical packaging methods for the foil products?

Foil products are generally wound on cores and packed in moisture‑resistant cardboard tubes or sealed plastic bags, then placed in export‑grade cartons. This protects against humidity and mechanical damage during transit.

Which Incoterms are most frequently used for shipments from this supplier?

Buyers commonly see FOB terms from major Chinese ports such as Shanghai, or CIF terms to European destinations, depending on the agreed logistics arrangement.

What is a realistic lead time for a first order of aluminium circles and foil?

Lead times of 30‑45 days are typical for extrusion of circles and foil slitting in China, assuming standard production schedules and no extraordinary customs delays.
