About King9 Technology Company Limited - Aluminum Sheets Supplier in China
China‑based King9 Technology Company Limited lists eight active products across Agriculture and Aluminum Sheets categories. The catalogue includes a mixture of standard and synthetic aluminium profiles such as Modules Aluminium Profile BT4040, Bt3060 Extrusion Aluminium Profile, and Green Frame BT3030, together with a single entry that specifies HS code 7604.21 for an Industrial Used Aluminum Profile Bt4545 made from Aluminum Alloy 6063‑T5 with Titanium Plating. The remaining items - industrial Used Aluminum Profile BT2020, Synthetic Aluminum Profile BT3030R, Aluminum Profile Bt4590 and Aluminum Bt1530 - are described without HS codes or material details in the supplied data.
The product set focuses on extruded aluminium sections that are commonly used for framing, construction, and equipment housings. The presence of a detailed HS code (7604.21) places at least one item in the tariff sub‑heading for aluminium extruded profiles, while the other items fall under the broader HS chapter 76 for primary aluminium products. No additional company‑specific certifications are listed in the source data.
Product Range and Specialties of King9 Technology Company Limited
The listed aluminium profiles span typical extrusion shapes such as rectangular, square and custom‑section bars. In the wider industry, extrusions are often supplied in grades 6061‑T6 or 6063‑T5, conforming to standards such as ASTM B221 or EN 755‑2, with tolerance ranges of ±0.2 mm for width and thickness and surface finishes ranging from mill finish to anodised coating. Common length offerings are 6 m or 12 m, and bulk shipments are usually packed in wooden crates or shrink‑wrapped bundles to protect the aluminium surface during transport. Buyers frequently request material certificates that confirm alloy composition, temper, and mechanical properties such as tensile strength (≈ 210 MPa for 6063‑T5).
Trade and Export Information - King9 Technology Company Limited
China is a leading exporter of aluminium extrusions, and HS code 7604.21 is routinely applied to profiles destined for the automotive, construction, and consumer‑goods sectors in the European Union, United States and Southeast Asian markets. Importers typically require compliance with ISO 9001 quality management, CE marking for EU applications, and RoHS conformity for electronic‑enclosure uses. Standard export logistics involve containerised loads - a 20 ft container can hold roughly 1.2 t of aluminium profiles, while a 40 ft container accommodates up to 2.4 t, packed in wooden pallets or bulk bundles. Common Incoterms are FOB Shanghai or CIF destination port, with customs documentation including the commercial invoice, packing list and the HS code declaration.
Sourcing from King9 Technology Company Limited - Buyer Guidance
When sourcing from King9 Technology Company Limited, buyers should request a Mill Test Certificate (MTC) that details alloy designation, temper, tensile strength and chemical analysis for each profile. For the item with HS code 7604.21, a product data sheet confirming the 6063‑T5 alloy and titanium plating thickness is advisable. Verify packaging specifications - typically wooden crates with internal separators - and confirm the minimum order quantity, which in the aluminium extrusion market often starts at one 20 ft container. Lead times for extruded sections from Chinese manufacturers range from 30 to 45 days after order confirmation, depending on profile complexity and finishing requirements.
Frequently Asked Questions About King9 Technology Company Limited
What aluminium alloy grades are offered by King9 Technology Company Limited?
The catalogue specifies an Industrial Used Aluminum Profile Bt4545 made from Aluminium Alloy 6063‑T5. The other listed profiles do not include alloy details, so buyers should request the specific alloy grade for each item.
Which HS code applies to the aluminium profiles?
Only the Industrial Used Aluminum Profile Bt4545 is identified with HS code 7604.21, which covers aluminium extruded profiles. Other products are not assigned an HS code in the provided data.
What certifications should a buyer request for these aluminium products?
Buyers should ask for a Mill Test Certificate and, where required by the destination market, ISO 9001, CE marking or RoHS compliance documentation.
How are the aluminium profiles typically packaged for export?
Standard practice is to pack extruded sections in wooden crates or shrink‑wrapped bundles, with internal separators to prevent surface damage during sea freight.
What is a typical minimum order quantity for aluminium extrusions from China?
In the aluminium extrusion market, the common MOQ is one 20 ft container, roughly 1.2 tonnes of product, unless a smaller sample quantity is arranged.
What lead time can a buyer expect for these aluminium profiles?
Lead times usually range from 30 to 45 days after order confirmation, depending on profile dimensions, surface treatment and current production schedules.
Are there any specific import duties or regulations for HS code 7604.21?
HS code 7604.21 is subject to anti‑dumping duties in some markets and generally requires a customs declaration with the correct HS code, origin certificate and any applicable trade agreement certificates.
How can a buyer verify the material composition of the aluminium profiles?
The Mill Test Certificate provides chemical composition and mechanical property data; buyers should compare this against the required alloy standard (e.g., 6063‑T5) before acceptance.
