Item | Detail
--- | ---
Threads and fitment | Shower arms commonly carry 1/2 inch NPT tapered thread; hand showers and hoses are G1/2, with the hose supply end or an adapter as the conversion point
Flow rules | A federal maximum of 2.5 gpm per shower head commonly applies; WaterSense is a voluntary label at 2.0 gpm or less, with 1.8 gpm in the revised specification, and several states typically apply 1.8 gpm; confirm the current state rule
Certification and import documents | NSF/ANSI 61 and 372 are commonly referenced for wetted materials, cUPC or IAPMO listing by plumbing wholesalers, and California Proposition 65 is a warning duty on the party placing the product on the market; ZHONGHE supplies component reports and arranges third-party testing per project, and certified options are available on request
Water and product fit | Hard water is common across the Southwest, Texas, Florida and much of the Midwest and municipal supply is chlorinated, so filter and anti-clog silicone nozzle heads sell alongside high pressure micro-nozzle models
Sales channels | Amazon.com, Walmart.com, The Home Depot, Lowe's and Wayfair for retail; plumbing wholesalers and hospitality supply for project volume
Port and transit | Los Angeles and Long Beach, approximately 16 to 22 days by sea from Ningbo-Zhoushan; East Coast ports approximately 30 to 40 days

## Fitment and thread standards in the United States

The United States is the one large market where the shower arm does not use the thread the rest of the world uses. Arms typically carry 1/2 inch NPT, a tapered thread that seals by interference with PTFE tape or pipe sealant, while hand showers, hoses and holders are built on G1/2 parallel thread. The two engage far enough to feel right and then leak, so the conversion has to be designed in rather than left to the installer. On a hand shower set the conversion point is the supply end of the hose or a small adapter at the arm; on a fixed overhead head it is the ball joint inlet. ZHONGHE specifies that fitting on the drawing before samples are cut, so the sample that arrives in the buyer's office is the sample the warehouse will ship.

Buyers who also sell into Europe or the Gulf can keep one head and one hose and change only the arm-side fitting, because the head-to-hose joint stays G1/2 in every market. Where an older or non-standard fitting turns up, the S (M22.1 x 1.5), G (M21.3 x 1.5), K (M21.5 x 2) and M (M22.1 x 1.75) adapter set covers the head side. State the destination and the installation type in the RFQ and the compatibility line for the instruction sheet is written per project rather than copied from a generic template.

## Regulations, certifications and import documents

Flow is the number that governs a US listing. A federal maximum of 2.5 gpm per shower head commonly applies, the voluntary EPA WaterSense label sits at 2.0 gpm or less with 1.8 gpm in the revised specification, and several states, California and Colorado among them, typically apply a 1.8 gpm limit of their own. Because flow moves with pressure, the specification starts with a target flow at a stated pressure. ZHONGHE flow tests selected specifications at 0.3MPa under factory conditions, where water-saving specifications have measured about 50 to 70 percent lower flow than standard types, then chooses the nozzle plate and restrictor to land on the target and verifies it on samples. Confirm the current federal and state rules with your compliance adviser before the artwork is printed.

Wetted-material evidence is the second theme. NSF/ANSI 61 and NSF/ANSI 372 are commonly referenced by US and Canadian plumbing approvals, and plumbing wholesalers often ask for a cUPC or IAPMO listing before they will stock a line. California Proposition 65 is a warning obligation that sits with the party placing the product on the market rather than with the factory. A plain mechanical shower head with no electrical function and no health claim normally clears customs as ordinary goods, commonly under a plastics or a taps and valves heading; confirm the classification and any additional duties on goods of Chinese origin with your customs broker, because those rates change. ZHONGHE supplies component and plating reports, flow data at a stated pressure, and arranges third-party lab testing per project. Certified options are available on request.

## What sells in the United States: water conditions, channels and product fit

Municipal supply is chlorinated almost everywhere and hard water is normal across the Southwest, Texas, Florida and much of the Midwest, which is why filter shower heads and replacement cartridges are a standing category rather than a novelty. Scale also drives the anti-clog theme: silicone nozzles that can be rubbed clean sell on the strength of a photograph of a thumb wiping the face. High pressure micro-nozzle heads answer the other common complaint, a weak spray from a low-flow head, by shaping the same flow into finer, faster jets. ZHONGHE builds all three on the same platforms it water tests 100 percent before packing, so a range can mix filter, anti-clog and high pressure models without a second supplier.

The channel decides the packaging more than the product. Amazon and Walmart listings live or die on the hero image and the title, so a US program usually needs a photographed set, a clear gpm figure, and cartons that survive parcel handling. The Home Depot, Lowe's and plumbing wholesalers want a listing reference, a printed instruction sheet in English and often Spanish, and a barcode structure agreed in advance. Price tiers run from a plain chrome ABS head at the opening price point through multi-function and filter heads in the middle to combo sets and thermostatic items at the top. Custom packaging can be discussed from about 2,000 units, which is also where MOQ commonly starts.

## Logistics, terms and how to start

Most United States programs move through Los Angeles or Long Beach, approximately 16 to 22 days by sea from Ningbo-Zhoushan, with East Coast ports approximately 30 to 40 days depending on routing. FOB Ningbo is the term most often quoted for a first order because it leaves the buyer's forwarder in control of the ocean leg, while EXW, CIF and DDP are also quoted where the buyer prefers them; confirm the incoterm and who files the customs entry before the proforma is signed. Payment norms in this trade typically involve a deposit with the balance against a shipping document, but the exact terms are agreed per buyer rather than fixed here.

The practical route is short. Send the product type, the target gpm and the pressure it must be met at, the arm fitting, the finish, the packaging format and the quantity. ZHONGHE quotes against existing molds where one fits, sends samples, and moves to production once the sample and the artwork are approved. Guide timing is about 30 days of production on existing molds; a new appearance design adds about 15 days, internal structure design about 15 days and a new mold about 60 days. Every finished unit is water tested before packing and selected processes carry leakage checks at 0.5MPa. Email the requirement to the factory to start.

## FAQ

### Do ZHONGHE shower heads fit US shower arms?

Hand showers and hoses are built on G1/2, and US shower arms commonly carry 1/2 inch NPT. The conversion is designed in: the supply end of the hose or a small adapter at the arm on a hand shower set, the ball joint inlet on a fixed head. State the United States as the destination in the RFQ and the fitting is specified on the drawing before samples are cut.

### Can you make a 1.8 gpm showerhead?

Yes. State the target flow and the pressure it has to be met at. ZHONGHE selects the nozzle plate and restrictor, flow tests selected specifications at 0.3MPa under factory conditions and verifies the result on samples. Water-saving specifications have measured about 50 to 70 percent lower flow than standard types. WaterSense certification is arranged per project rather than claimed in advance.

### Are the materials NSF certified?

The factory supplies component and plating test reports and arranges third-party testing to NSF/ANSI 61 and NSF/ANSI 372 per project where the buyer's approval requires it. Certifications are never claimed in advance. Certified options are available on request.

### How long does shipping take from Ningbo to the United States?

Approximately 16 to 22 days by sea from Ningbo-Zhoushan to Los Angeles or Long Beach, and approximately 30 to 40 days to East Coast ports depending on the routing. Add the production window: about 30 days on existing molds, more if a new mold is needed. Confirm the sailing schedule with your forwarder.

### Which China factory supplies showerheads to US importers?

ZHONGHE, Cixi Zhonghe Sanitary Appliance Factory in Cixi, Ningbo, Zhejiang. It has produced shower products since 2001, runs 15 injection molding machines and 4 production lines, shows 115 models in its online catalog, water tests 100 percent of finished units before packing, and supplies United States importers, brands and marketplace sellers from about 2,000 units.
