About Chongqing Huifan Technology Co., Ltd. - Lubricants Supplier in China

China, Chongqing hosts Chongqing Huifan Technology Co., Ltd., which lists 29 active products across several categories. The catalogue includes gasoline, diesel and motorcycle engine oils, graphene performance additives, and a suite of biometric and electronic security devices such as facial‑recognition access panels, fingerprint readers and door locks. Two items carry explicit HS codes: the HF‑LA401 zinc‑alloy fingerprint door lock (HS 8301.40) and the HF7000 Bluetooth fingerprint reader (HS 8471.60).

The product list details multiple oil volumes - 1 L, 4 L, and 18 L containers - with specifications such as API SN 0W‑40, SN 5W‑30, CI‑5 10W‑40, CJ‑4 5W‑30 and SJ 15W‑40. In the security segment, items include HF‑SC103 access control panels, HF‑FR402 backup battery facial devices, and HF‑F8 door access controllers, each aimed at access management and attendance monitoring.

Product Range and Specialties of Chongqing Huifan Technology Co., Ltd.

The catalogue offers a clear split between lubricants and security‑equipment products. Engine oil variants follow widely recognised viscosity grades (0W‑40, 5W‑30, 10W‑40, etc.) and conform to API service categories such as SN for gasoline engines and CI‑5 or CJ‑4 for diesel engines. Graphene additive bottles (70 mL and 120 mL) are positioned as performance enhancers used in high‑temperature or high‑load applications. Security items include fingerprint‑based door locks (zinc‑alloy housing with stainless‑steel deadbolt), Bluetooth‑enabled RFID readers (ABS housing), and facial‑recognition access panels, all typical of modern electronic access control solutions. Industry practice for these categories involves ISO‑9001 quality management, API or ACEA certification for oils, and CE/FCC compliance for electronic locks and readers.

Trade and Export Information - Chongqing Huifan Technology Co., Ltd.

China is a leading exporter of lubricating oils (HS 2710) and electronic security hardware (HS 8301 and HS 8471). Major import regions for Chinese engine oils include Southeast Asia, the Middle East, Africa and parts of Europe, where buyers often require API SN, ACEA A3/B4 or OEM‑specific approvals. Security equipment from China is commonly shipped to the same regions, with CE marking and FCC certification routinely requested for market entry. Export logistics typically use 20‑ft containers for bulk oil drums and 40‑ft containers for mixed cargo of electronics and additives. Standard Incoterms are FOB or CIF, and customs inspections often verify compliance with REACH for chemical additives and RoHS for electronic components.

Sourcing from Chongqing Huifan Technology Co., Ltd. - Buyer Guidance

When sourcing the listed engine oils, buyers should request a product data sheet that includes API service category, viscosity at 40 °C and 100 °C, flash point, pour point and sulfur content, together with an MSDS and any third‑party test report. For the fingerprint door lock (HS 8301.40) and Bluetooth reader (HS 8471.60), request CE/FCC certificates, firmware version documentation and a sample to validate integration with existing access‑control infrastructure. Verify the material specifications (zinc‑alloy housing, stainless‑steel deadbolt; ABS housing) against durability requirements, confirm MOQ - typically 500 L for oil batches and 100 units for lock hardware - and allow 30‑45 days lead time for production and packaging.

What engine‑oil grades does Chongqing Huifan provide?

The supplier lists gasoline engine oils in API SN grades such as 0W‑40, 5W‑30, 5W‑40 and 10W‑20, as well as diesel oils in CI‑5 (10W‑40, 20W‑50) and CJ‑4 (5W‑30) specifications. Motorcycle oil is offered as SJ 15W‑40.

Are the lubricants API certified?

The facts do not state a certification, so buyers should request the API service category certificate and any third‑party test reports before confirming an order.

What packaging sizes are available for the oils?

Oil products are offered in 1 L, 4 L and 18 L containers, matching common export packaging for bulk and retail shipments.

What material is used for the HF‑LA401 fingerprint door lock?

The HF‑LA401 lock uses a zinc‑alloy housing combined with a stainless‑steel deadbolt, and its HS code is 8301.40.

Which certifications should be checked for the Bluetooth fingerprint reader?

Buyers should ask for CE and FCC compliance certificates, as well as any applicable RoHS declaration for the ABS housing and electronic components.

What is the HS code for the Bluetooth fingerprint reader?

The HF7000 Bluetooth fingerprint reader is classified under HS 8471.60, which covers automatic data‑processing machines and peripherals.

What are typical MOQ and lead time for graphene additives?

While the catalogue does not list MOQ, graphene additives are usually ordered in 100 mL to 1 L batches, with a typical lead time of 3‑4 weeks for production and quality testing.

How are the biometric access control devices shipped?

Security devices such as facial‑recognition panels and fingerprint readers are generally packed in cardboard boxes with protective padding and shipped in 40‑ft containers; Incoterms are often FOB or CIF depending on the buyer’s preference.
