About Henan Sigma Industrial Co., Ltd - Aluminum Products Supplier in China

Henan Sigma Industrial Co., Ltd operates from Henan province in China and currently maintains a catalogue of 15 active products. The catalogue spans several aluminium‑related categories, including aluminium plates, aluminium hardware, aluminium die‑cast parts, aluminium boring scrap, aluminium coil scrap, and aluminium containers, as well as a range of artificial flower items. The aluminium items are listed under HS chapter 76, with specific codes such as 7602.00 for aluminium slugs, 7604.29 for extrusion housings, 7606.12 for checkered plates, and 7612.10 for collapsible tubes. The artificial flower and related decorative products appear under HS chapters 67 and 06, reflecting their composite silk‑plastic construction. The supplier’s product list therefore combines metal manufacturing and decorative synthetic goods.

Key aluminium offerings include a 1070‑grade PIR aluminium slug (HS 7602.00) and a 1050‑grade PIR slug, both fabricated from standard aluminium alloy grades used in extrusion and stamping. The company also supplies embossed aluminium checkered plates (HS 7606.12) and five‑bar anti‑slip aluminium sheets, which are typical for flooring and platform applications. Additional metal products comprise aluminium capacitor cases and profile shells (HS 7604.29) and aluminium aerosol cans for cosmetics (HS 7613.00). The artificial product line lists silk‑screen printed artificial flowers (HS 6702.90), silk‑fabric roses (HS 0604.90), and various synthetic grass and lawn items, though these items lack specific HS codes in the catalogue. Overall the catalogue reflects a focus on aluminium extrusion, sheet forming, and decorative synthetic goods.

Product Range and Specialties of Henan Sigma Industrial Co., Ltd

Henan Sigma’s aluminium catalogue includes PIR aluminium slugs of 1050 and 1070 alloy composition, embossed checkered plates made from 5052 aluminium alloy, and custom aluminium extrusion housings for electronic components. In the aluminium industry, 1050 and 1070 alloys are part of the 1xxx series, offering high electrical conductivity and good formability, and are commonly supplied to the automotive, construction, and consumer‑electronics sectors. Standard specifications such as ASTM B209 for sheet and plate, and ISO 6361 for aluminium alloys, define thickness tolerances, tensile strength, and surface finish that buyers typically request. The company also lists aluminium aerosol cans for cosmetics, which are generally produced to meet ISO 9001 quality management and, for cosmetic applications, must comply with EU Regulation 1223/2009 on cosmetic packaging.

The artificial flower segment comprises silk‑screen printed bouquets, polyester‑fabric roses, and composite silk‑plastic stems, categorized under HS 6702 and 0604. Buyers of artificial floral products usually evaluate colour fastness (ISO 105), flame retardancy (EN 71‑3), and material composition certificates, especially for export to European and North American markets. Synthetic grass and lawn items, while not assigned HS codes in the catalogue, fall under HS 57xx and are typically shipped in bulk rolls with moisture content below 10 % to prevent mold during transit.

Trade and Export Information - Henan Sigma Industrial Co., Ltd

China is one of the world’s largest exporters of aluminium semi‑finished products, and items classified under HS 7602, 7604, and 7606 are routinely shipped to Europe, North America, and Southeast Asia for use in automotive panels, building construction, and electronic housings. Export shipments commonly employ 20‑ft or 40‑ft containers with bulk packing or wooden crates, and buyers often require the supplier to provide a Certificate of Origin, commercial invoice, and packing list aligned with Incoterms CIF or FOB. For aluminium products intended for the EU market, CE marking and compliance with REACH chemical restrictions are standard expectations.

Artificial floral and synthetic turf products from China are primarily destined for the United States, European Union, and Middle‑East decor markets, where HS 6702 and 0604 items are subject to textile and toy safety regulations such as the EU REACH and US Consumer Product Safety Commission (CPSC) standards. Importers typically request material safety data sheets (MSDS), fire‑retardancy test reports, and compliance certificates for colour fastness. Packaging for these lightweight items usually involves poly‑bag bulk packs or cardboard cartons, with moisture barriers to protect against humidity during sea freight.

Sourcing from Henan Sigma Industrial Co., Ltd - Buyer Guidance

Buyers sourcing aluminium slugs or checkered plates should request an alloy certification that confirms the 1xxx series designation, along with tensile strength, elongation, and conductivity test results per ASTM B211. For extrusion housings and capacitor cases, a dimensional drawing and tolerance verification (e.g., ±0.2 mm for critical dimensions) are advisable before confirming order quantities. An ISO 9001 quality management certificate and a recent factory audit report provide additional assurance of process control.

When procuring artificial flowers, buyers should obtain a sample to assess colour accuracy, stitch quality, and stem flexibility, and request a colour‑fastness test (ISO 105‑B02) and a flame‑retardancy certificate (EN 71‑3) if the end market requires it. Documentation such as a Material Safety Data Sheet, a certificate of compliance with REACH, and a packaging weight list are standard for bulk orders. Verification of the HS code classification and proper labeling on the commercial invoice helps avoid customs delays.

What aluminium alloy grades does Henan Sigma offer for its slugs?

The catalogue lists 1050 and 1070 PIR aluminium slugs, which correspond to the 1xxx series aluminium alloys commonly used for high conductivity and formability. Buyers can request the alloy certification sheet that details chemical composition and mechanical properties.

Which HS codes apply to the aluminium checkered plates supplied by Henan Sigma?

The checkered plates and five‑bar anti‑slip sheets are classified under HS code 7606.12, which covers aluminium plates, sheets and strips, other than those of a kind used for the building trade. The HS code is consistent across the embossed plate products in the catalogue.

What documentation should be requested for the aluminium aerosol cans intended for cosmetics?

Buyers should ask for a Certificate of Origin, an ISO 9001 quality management certificate, and a compliance statement referencing EU Regulation 1223/2009 on cosmetic packaging. A test report confirming the can’s pressure resistance and internal coating integrity is also typical.

How are the artificial flowers from Henan Sigma classified for customs?

The artificial bouquets, silk‑screen printed flowers and polyester‑fabric roses fall under HS code 6702.90 (other artificial flowers and parts), while the silk‑fabric rose heads are listed under HS code 0604.90 (other natural or artificial flowers). These codes align with the material composition described in the catalogue.

What quality tests are commonly required for synthetic grass and lawn products?

Importers usually request a moisture content measurement (target below 10 %) and a UV‑stability test to ensure colour retention. A fire‑retardancy test (EN 13501‑1) may be required for markets that enforce building material safety standards.

What packaging formats are typical for Henan Sigma’s aluminium tubes and containers?

Collapsible aluminium tubes (HS 7612.10) are generally packed in cardboard cartons with internal protective inserts, while larger aluminium containers are shipped in wooden crates or bulk steel drums, depending on size. All packaging complies with ISO 11607 for medical‑grade containers when applicable.

Which certifications are most relevant for the aluminium extrusion housings used in electronics?

Buyers often look for ISO 9001 and ISO/TS 16949 (automotive quality) certificates, as well as RoHS compliance documentation that confirms the absence of lead, mercury, cadmium and other restricted substances. A test report showing dimensional accuracy and surface finish (e.g., Ra ≤ 0.8 µm) is also customary.
