About Welcharm Hardware Products Co., Ltd. - Door Locks Supplier in China

China hosts Welcharm Hardware Products Co., Ltd., which currently lists seven active products in its catalogue. The items fall under the door‑hardware segment and include a Window Handle (HS 8302.41), Sliding Door Lock With Key (HS 8301.30), Sliding Door Hook Lock With Key (HS 8301.40), Zinc Alloy Window Lock (HS 8301.40), Power Spraying Window Handle Lock, Iron Sliding Window Handle Lock and Oxidation Aluminum Alloy Window Lock. Each product is classified under HS chapters 8301 (locks) or 8302 (handles), reflecting standard customs tariff groupings for metal hardware. The catalogue emphasizes a mix of lock mechanisms and handle accessories for residential and commercial door applications.

The listed hardware uses zinc‑alloy or aluminum bases, with some models incorporating a steel bolt or steel core for added strength. Where material details are provided, the zinc alloy is described as a zinc‑based die‑casting alloy, while the aluminum variant is noted as oxidation‑treated. No other product specifications such as finish or dimensions are supplied, but the range covers both sliding‑door and window‑type locking solutions. The supplier’s focus on door‑lock hardware aligns with its top category designation of Door Locks.

Product Range and Specialties of Welcharm Hardware Products Co., Ltd.

Welcharm’s catalogue includes a standard window handle (HS 8302.41) typically produced from zinc alloy or aluminum, which in the industry is often cast as Zamak 3 or 6063‑T5 alloy for a balance of strength and corrosion resistance. The sliding‑door lock with key (HS 8301.30) and the hook‑type lock (HS 8301.40) are usually fabricated from zinc alloy bodies with steel bolts or cores; common grades are Zamak 5 for the body and C45 steel for the bolt, providing tensile strengths around 300 MPa. The zinc‑alloy window lock (HS 8301.40) follows similar die‑casting standards, while the oxidation‑treated aluminum lock uses anodised finishes that meet ASTM B580 for corrosion protection. Industry buyers often request lock mechanisms that meet ANSI/BHMA standards for durability, typically testing for a minimum of 500 N closing force and a 10 kg load rating.

Trade and Export Information - Welcharm Hardware Products Co., Ltd.

Chinese manufacturers of door‑hardware frequently export to Southeast Asian markets, the European Union and North America, where building‑fit‑out projects drive demand for standardized lock sets. The HS 8301 and 8302 families are subject to routine customs inspections, and buyers usually ask for a pre‑shipment inspection report from SGS or Bureau Veritas. Common certifications requested for this product class include CE marking for EU compliance, ISO 9001 quality‑management certification, and RoHS compliance for restricted substances. Export shipments are normally packed in corrugated boxes on wooden pallets, with a typical 20‑ft container holding approximately 2,000‑2,500 units depending on packaging density. FOB Shanghai or CIF destination ports are the most used Incoterms for hardware trade from China.

The Chinese hardware sector benefits from well‑developed logistics corridors, and many exporters work with freight forwarders experienced in handling metal hardware to ensure consistent moisture levels and prevent surface oxidation during transit. Buyers should verify the HS code classification on the commercial invoice to avoid tariff mis‑applications, especially between 8301.30 (keyed locks) and 8301.40 (hook or core locks).

Sourcing from Welcharm Hardware Products Co., Ltd. - Buyer Guidance

When sourcing from Welcharm, buyers should request a material composition certificate confirming the zinc‑alloy or aluminum grade, as well as a mechanical test report showing bolt tensile strength and lock‑force values. A product sample with the final surface finish (e.g., powder‑coat, chrome‑plating, or anodised) helps verify compliance with ANSI/BHMA or EN 12209 standards that many importers apply. Buyers are advised to ask for a CE Declaration of Conformity and, if required by the destination market, an ISO 9001 audit summary or RoHS statement before confirming the order. Typical minimum order quantities for Chinese door‑hardware range from 500 to 1,000 pieces per lock type, with lead times of 30‑45 days after sample approval.

Verification of the HS code on the pro‑forma invoice, together with a third‑party inspection report, reduces the risk of customs delays. Requesting packaging dimensions and pallet configuration in advance aids in freight planning, especially for container load optimisation.

What product categories does Welcharm list in its catalogue?

Welcharm lists seven hardware items, including a window handle, two sliding‑door lock models with keys, a zinc‑alloy window lock, a power‑spraying window handle lock, an iron sliding window handle lock and an oxidation‑treated aluminum window lock.

Which HS codes are associated with Welcharm’s lock products?

The catalogue assigns HS 8301.30 to the Sliding Door Lock With Key, HS 8301.40 to the Sliding Door Hook Lock With Key, the Zinc Alloy Window Lock and the Oxidation Aluminum Alloy Window Lock. The Window Handle falls under HS 8302.41.

What materials are used for the listed locks?

Materials include zinc‑alloy die‑casting alloys (often Zamak grades), steel bolts or cores for the keyed and hook locks, iron for the sliding window handle lock, and oxidation‑treated aluminum for one window lock variant.

Which certifications should a buyer request for these hardware items?

Buyers typically request CE marking for EU markets, ISO 9001 quality‑management certification, and RoHS compliance statements. A third‑party inspection report (e.g., SGS) is also standard practice.

What are typical packaging and shipping formats for these products?

Products are usually packed in corrugated boxes, placed on wooden pallets, and shipped in 20‑ft or 40‑ft containers. A 20‑ft container can hold roughly 2,000‑2,500 units depending on box size.

What sample or test documentation is advisable before placing a bulk order?

Request a physical sample showing the final finish, a material composition certificate, and mechanical test data such as bolt tensile strength and lock‑force measurements that meet ANSI/BHMA or EN 12209 criteria.

What are common lead times and MOQ for door‑hardware from China?

Lead times are generally 30‑45 days after sample approval, with minimum order quantities typically ranging from 500 to 1,000 pieces per lock type.

How should a buyer verify the correct HS code for customs?

The buyer should confirm the HS code on the pro‑forma invoice matches the product type - 8301.30 for keyed locks, 8301.40 for hook or core locks, and 8302.41 for handles - to avoid mis‑classification and potential tariff issues.
