unishellcap.com Class 6 Trademark No. 89206577 | Uniseel

Registered: unishellcap.com Is Now a Class 6 Trademark (No. 89206577)

On 14 September 2026, the China National Intellectual Property Administration (CNIPA) registered the word mark "unishellcap.com" in Class 6 under registration number 89206577. The holder is Hangzhou Uniseel Technology Co., Ltd.; the registration runs until 13 September 2036 and covers ten goods in the metal packaging class, from metal bottle caps to metal screw caps for bottles. For buyers this is not a decorative detail. The name you found us under is now a registered right attached to the exact products we make, and it can be checked in a public database by anyone before they place an order.

1. What the certificate actually says

Trademark certificates are short documents, and it is worth reading them literally. This is what registration 89206577 states, field by field.

Field	Content of the registration
Mark	unishellcap.com (word mark)
Registration number	89206577
Class	6 (international classification)
Holder	Hangzhou Uniseel Technology Co., Ltd.
Holder credit code	91330185MAK22A2C47
Holder address	Room 205, Building 11, No. 57 Hongqiao, Hongqiao Village, Gaohong Town, Lin'an District, Hangzhou, Zhejiang, China
Registration date	14 September 2026
Valid until	13 September 2036
Issuing authority	China National Intellectual Property Administration (CNIPA)

Two details in that table matter commercially. First, the holder is a named legal entity with a registration code, not a trading style, so the right can be traced to one company. Second, the term is ten years: 2026 to 2036. A registration is not taken out for a single season of business.

2. The ten goods covered in Class 6

Class 6 is the class for goods of common metal. The certificate lists ten items, which is the scope the registration actually protects. They are reproduced below in the original Chinese, with our working English translation for international buyers. The legally binding wording is the Chinese original.

Item (Chinese, as on the certificate)	Working English translation
金属瓶盖	metal bottle caps
金属密封盖	metal sealing caps
容器用金属盖	metal lids for containers
金属盖瓶	metal bottles fitted with caps
瓶用金属塞	metal stoppers for bottles
金属瓶帽	metal caps for bottles
瓶用金属螺旋盖	metal screw caps for bottles
金属板条	metal strips and slats
五金器具	small metal hardware
金属地板	metal flooring

Read the list as a product map rather than a formality. It covers the closures we sell (caps, sealing caps, lids, screw caps), the components that surround them (stoppers, hardware), and the input material family we work in (metal strip). When a buyer asks what a supplier is actually registered for, this is the answer for us: internal-thread tinplate closures and the metal packaging hardware around them.

3. Why register a website name as a trademark

A domain name and a trademark are different rights, and only one of them can be enforced against a copyist. A domain gives you the right to resolve a name to a server. A trademark gives you the right to stop someone else from using a confusingly similar sign on the same class of goods. Registering the site name in Class 6 closes the gap between the two.

• The name is our shopfront. Buyers searching for a supplier often find the website before they find the company, so the website name is the sign that has to be protected.
• Class 6 ties the sign to goods, not to a website. Protection follows the products: caps, sealing caps, screw caps and the rest of the list above.
• It creates a verifiable record. Anyone can look up 89206577 and see the holder, the scope and the term without emailing us.
• It supports enforcement. Where a look-alike name is used on the same goods, a registration is the instrument that makes a complaint possible, on marketplaces as much as in a direct dispute.
• It protects the search term itself. Buyers do not search for our legal name; they search for the product name and the site name. Both are now anchored to a registered right.

In short: the registration converts a marketing asset into an enforceable one, and it does so in the class where our products actually sit.

4. Who holds the mark, and who runs the site

Because the group uses more than one company name, the honest answer needs a second sentence: the trademark holder and the operator of unishellcap.com are two different companies in the same group. That is deliberate, and it is worth stating plainly.

Entity	Role in the group	What it means for you
Hangzhou Uniseel Technology Co., Ltd.	Trademark holder for unishellcap.com; the group's international division, promoting the Uniseel brand at www.uniseel.com	Signs export contracts and export documentation
Hangzhou Shengshi Metal Cap Co., Ltd.	Operator of this site, unishellcap.com; the group's domestic sales department	Handles sales inside China
Hangzhou Lin'an Shengxiang Technology Co., Ltd.	The group's manufacturing entity	Runs the production lines that make the closures

Three names, one group, one factory. The trademark belongs to the entity that takes the products abroad; the site you are reading is run by the entity that serves the domestic market; the goods themselves come from the group's manufacturing company. If you arrived here from a search engine and wondered whether unishellcap.com and uniseel.com are the same business, this is the answer: same group, different divisions, different markets.

5. What the registration means for a buyer

A registered trademark is a small piece of due diligence that costs nothing to perform.

• You can verify us before ordering. Search the number 89206577 in the CNIPA trademark database and compare the holder name and the goods list against the products you are buying.
• The goods list matches the catalogue. The closures quoted to you fall inside the registered scope, which is what makes the registration meaningful rather than decorative.
• The holder is identifiable. Contracts, certificates and food-contact statements are issued by a named entity with a credit code, not by an unregistered brand name.
• It reduces substitution risk. A supplier that has registered its own sign in the class has a reason to defend that sign, and something to lose by selling a different product under it.

6. Registered at home, promoted abroad

The reason we registered this name in Class 6 is not administrative tidiness. It is the clearest statement we can make that we intend to sell these products under our own brands, in China and outside it, for a long time.

At home, the group sells through Hangzhou Shengshi Metal Cap Co., Ltd., its domestic sales department, with local invoicing and local documentation. Abroad, the group's international division, Hangzhou Uniseel Technology Co., Ltd., promotes the Uniseel brand from www.uniseel.com, issues English-language quotations and works through the compliance requirements that European and North American buyers now expect on packaging.

That second half is where the registration earns its keep. Export customers ask harder questions than domestic ones: who is the legal entity, what is the food-contact status of the material, what happens to the packaging at end of life in the European Union. Our export documentation is built around the standards those buyers audit against, including food-contact requirements such as FDA 21 CFR 175.300 and the EU plastics framework (EU) 10/2011 and (EU) 2024/3190 for BPA-free materials, REACH and RoHS declarations, and the packaging and PFAS-free test reports prepared for the EU Packaging and Packaging Waste Regulation (EU) 2025/40 ahead of its application. Those documents are listed with their report numbers in section 7. A trademark that lasts ten years is the same ten-year horizon those obligations assume.

Put the two together and the position is straightforward: one group, one production source, two sales arms, and a brand that is registered in the market where the goods are made and promoted in the markets where they are sold.

One limitation is worth stating, because buyers' legal teams ask about it. Registration 89206577 is a Chinese national registration: it protects the sign in China, which is where the goods are manufactured and where a component name is most likely to be copied. It does not by itself create rights in the European Union or the United States. That is why the export side of the group maintains its own filings and compliance documentation for the markets it ships to: a European buyer purchasing under the Uniseel brand deals with the group's international division, which is responsible for the registrations and declarations relevant to those markets. If your purchasing process requires a specific document - a trademark extract, a food-contact declaration, a packaging EPR registration number - ask for it with the quotation and it will be issued together with it.

7. The quality behind the name, certificate by certificate

A registration is only worth defending if the product behind it is consistent. Because three companies are involved, it is worth showing which entity holds which certificate and what each document actually covers. Every number below is quoted from the document itself, and each can be checked with the issuing laboratory or certification body.

Certification:

Logistics pallet, PPWR compliance	CANPC26015408305	16 June 2026	Shengxiang Technology
Stretch film, PPWR compliance	CANPC26015408306_1	22 June 2026	Shengxiang Technology

Two things are worth noticing in those three tables. First, the certificates are held by the entity that is legally responsible for what they describe: the factory holds the quality management system certificate, because the system being certified is production; the export entity holds the CE conformity certificate and the product test reports, because they are issued against the product as it is placed on the market; and the manufacturing entity holds the material and packaging declarations, because they describe the goods as they are made. Second, the numbers interlock: the CE certificate SC-ROHS-2026-06-02 names report CANPC26009364903 as its initial type test, which is the same RoHS report listed above. A registration number that can be traced from one document to another is worth more than a logo on a page.

• Internal-thread metal closures are formed on our own patented tooling, which is how we hold internal thread tolerances to +/- 0.1 mm - the variable that decides whether a cap seals and stays tight on a filling line.
• Tinplate is sourced from WISCO-NIPPON STEEL Tinplate Co., Ltd. (WINSteel) in Wuhan, the joint venture between WISCO of China Baowu and Nippon Steel, so thickness and coating consistency are controlled at the coil stage.
• Production capacity stands at 250,000 pieces per day, which is what allows a 100,000-piece order to be treated as a standard run rather than an exception.

8. How to verify the registration yourself

If you would like to check the registration rather than take our word for it, the whole exercise takes a few minutes.

• Open the CNIPA trademark search service and search for registration number 89206577.
• Confirm the holder reads Hangzhou Uniseel Technology Co., Ltd., and note the registration date of 14 September 2026 and the expiry date of 13 September 2036.
• Compare the listed goods against the products in your own quotation. If the item you are buying is not covered by the registration, ask us why - we would rather you checked.
• Ask us for the certificate PDF and the company registration details; both are supplied with quotations on request, free of charge.

Q5. How long does the registration last?

A5. Ten years, from 14 September 2026 to 13 September 2036. A ten-year term, rather than a short-lived filing, is the clearest signal of how long we expect to be selling under this name.

Q6. Why register a website name as a trademark?

A6. A domain only gives the right to use an address. A Class 6 registration ties the name to the goods themselves, makes it enforceable against confusingly similar signs used on the same products, and makes the right publicly checkable by any buyer.

Q7. How can I verify the registration myself?

A7. Search the CNIPA trademark database for number 89206577, confirm the holder reads Hangzhou Uniseel Technology Co., Ltd., and compare the listed goods with your own quotation. The certificate PDF is supplied with quotations on request.

Q8. Which company should I contact for export orders, and which for orders in China?

A8. Export orders go to Hangzhou Uniseel Technology Co., Ltd. through www.uniseel.com; orders inside China are handled by Hangzhou Shengshi Metal Cap Co., Ltd. Manufacturing is carried out by the group's production entity, Hangzhou Lin'an Shengxiang Technology Co., Ltd., in Hangzhou, Zhejiang.

Q9. Does the trademark also cover the Uniseel brand?

A9. They are separate rights. Registration 89206577 protects the sign "unishellcap.com" in Class 6. The Uniseel brand is promoted internationally from www.uniseel.com by the group's international division. For buyers, the practical point is that both names belong to one group and one factory.

Q10. What products can I buy under these names?

A10. Internal-thread tinplate closures in 38/400, 45/400, 53/400, 58/400 and 70/400 finishes, in silver or gold finishing and with a liner (induction heat-seal, pressure-sensitive or aluminium foil), for food, beverage, pharmaceutical, nutraceutical and personal-care packaging. Production capacity is 250,000 pieces per day.
