About Periwell International Business - Agriculture Supplier in China

China hosts Periwell International Business, an imported‑tier supplier that currently lists five distinct products across its catalogue. The company’s active product count of 5 covers items in agriculture‑related machinery, machined components, telecommunication infrastructure equipment, and metal castings, reflecting the four top categories reported. Each entry is identified by its functional name rather than a brand, and the catalogue includes a lamp shell, a communication base station, a universal heatsink, a textile‑machine frame, and a precision casting product for train components. The precision casting entry carries HS code 8483.60, which belongs to the broader HS chapter 84 that covers machinery and mechanical appliances. The other four items are not assigned HS codes in the supplied data, so no HS classification is stated for them.

The listed products span several material families. The precision casting product is described as being made from carbon steel ZG270‑480, alloy steel, or stainless steel 304, indicating a range of mechanical properties suitable for high‑strength and corrosion‑resistant applications. The lamp shell, communication base station, universal heatsink and textile‑machine frame are presented without material specifics, but their functional categories imply typical use of aluminum alloys, steel grades, or composite materials common in these sectors. The supplier’s catalogue therefore provides a concise view of five product types that can be matched to standard industry specifications for each class.

Product Range and Specialties of Periwell International Business

Periwell International Business lists a lamp shell, a communication base station, a universal heatsink, the frame of a textile machine, and precision casting products for train parts. In the metal‑casting entry the material options include carbon steel ZG270‑480 (often used for high‑strength forged parts), alloy steel variants, and stainless steel 304, which meets the ASTM A240 standard for corrosion‑resistant applications. Typical lamp shells for industrial lighting are fabricated from die‑cast aluminum or high‑impact polystyrene, with IP65 protection and heat‑dissipation designs. Communication base stations generally follow IEC 62209 and include RF shielding, with chassis constructed from cold‑rolled steel or aluminum extrusion. Universal heatsinks are commonly made of extruded aluminum with a thermal conductivity of 205 W/m·K and fin density designed to achieve a thermal resistance below 0.5 °C/W. Frames for textile machines are usually fabricated from structural steel (e.g., Q235) or cast iron, with tolerances of ±0.2 mm for critical alignment points. These industry norms provide a baseline for evaluating the supplier’s offerings.

Trade and Export Information - Periwell International Business

China is a major exporter of machined components and metal castings, and products such as those listed by Periwell International Business typically flow to industrial hubs in Europe, North America, and Southeast Asia. The HS code 8483.60 for precision casting products places the item in the category of "parts of machines of heading 84," which often requires conformity to ISO 9001 quality‑management systems and, for railway applications, compliance with EN 15227 crash‑worthiness standards. Telecommunication equipment like the communication base station is frequently subject to CE marking for the EU market and FCC certification for the United States, along with RoHS compliance for hazardous substance limits. Standard export packaging includes wooden pallets or bulk crates sized for 20‑ft or 40‑ft containers, and Incoterms such as FOB Shanghai or CIF Europe are commonly used. Buyers should verify that the supplier can provide the necessary test reports and certificates that match these regulatory expectations.

Sourcing from Periwell International Business - Buyer Guidance

When sourcing the lamp shell, request material data sheets that specify the alloy composition and IP rating, and ask for a sample to confirm surface finish and heat‑dissipation performance. For the communication base station, obtain a copy of the CE Declaration of Conformity, FCC ID documentation, and any applicable RF exposure test results before placing a trial order. The universal heatsink should be accompanied by a thermal resistance test report and confirmation of the aluminum alloy temper (e.g., T6). For the textile‑machine frame, ask for a mill test certificate that lists the steel grade and tensile strength, as well as dimensional inspection reports. The precision casting train part requires a material certificate for the selected steel grade (ZG270‑480, alloy steel, or 304 stainless) and a casting defect analysis report. Across all items, request a recent ISO 9001 audit report, verify the supplier’s export license, and confirm packaging dimensions and container loading plans to avoid freight surprises.

What HS code applies to the precision casting product offered by Periwell International Business?

The precision casting product for train parts is classified under HS code 8483.60, which falls within the chapter covering parts of machines of heading 84.

Which material grades are specified for the precision casting items?

The catalogue lists carbon steel ZG270‑480, various alloy steels, and stainless steel 304 as material options for the precision casting products.

What certifications should a buyer request for the communication base station?

Buyers should request CE marking documentation for EU markets, FCC ID for US markets, and RoHS compliance certificates to ensure the base station meets typical regulatory requirements.

Are there standard quality‑management systems expected for these Chinese machined components?

Importers commonly require an ISO 9001 quality‑management system audit report from Chinese suppliers of machined components and metal castings.

What typical packaging is used for the listed products when exported from China?

Export shipments are usually packed on standard wooden pallets, with bulk items placed in 20‑ft or 40‑ft containers depending on volume and weight.

What technical data should be reviewed for the universal heatsink?

The heatsink should be accompanied by a thermal resistance measurement (≤ 0.5 °C/W) and an aluminum alloy specification indicating a conductivity of around 205 W/m·K.

Which industry standards apply to the frame of a textile machine?

Textile‑machine frames are typically fabricated from structural steel meeting ASTM A36 or equivalent, with dimensional tolerances of ±0.2 mm for critical mounting points.

What documentation is advisable before ordering the lamp shell?

Request a material data sheet that confirms the alloy type, an IP rating (commonly IP65 for industrial lighting), and a sample to verify finish and fit.
