Asia Stamps & Seals Guide

Europe treats stamps and seals as "optional, mostly." Asia is a different story. Walk into a business meeting in Beijing, Tokyo, or Seoul, and the seal on the table often carries more legal weight than anyone's signature. This matters if you're a Nigerian firm sourcing from China, licensing tech from Japan, or exporting to the Gulf. It's not just a cultural detail. It can decide whether your deal actually binds the other side, or not.

This post is part of our global stamps & seals series. See the full 7-continent summary for the complete picture.

China: Where the Seal Is the Company's Signature

China runs one of the strongest seal systems in the world. The official company chop (公章) is not just a formality. Under Chinese law, a document stamped with the registered company chop is treated as proof the company agreed to it, unless someone proves otherwise. This holds true even if no signature appears next to it. Whoever holds the chop holds real power. That person can bind the company to deals, money debts, and official filings.

A company chop only counts as legal if a licensed vendor, approved by the government, makes it. It must also be filed with the Public Security Bureau (PSB). An informal or unregistered chop is simply invalid. Most Chinese firms hold several different chops for different jobs. These include the main company chop (the most powerful one), a bank and tax chop, a contract chop, an invoice chop (fapiao), and a personal chop for the legal head. Each chop only does its one job. This is a safety step, so no single chop can do everything. Faking a company chop is a crime in China. It can mean up to three years in jail. Real disputes have come from exactly this. In a well-known 2020 case, Tencent and a Chinese chili oil maker had a dispute. People had faked the company's chop and used it to sign an ad deal nobody approved.

Going digital hasn't skipped this system — it's been built into it. Under China's Electronic Signature Law (last updated in 2019), a properly registered electronic chop carries the same legal weight as the physical one. This holds true as long as only the signer controls the data behind it, and any change to it can be spotted. It's a good reminder: the value was never in the ink or the metal. It was always about who is allowed to hold it. That's just as true for a Chinese chop as it is for a freshly engraved Nigerian company seal locked in your own office drawer.

Rule of thumb: keep strict custody records for every chop your company holds. Report any loss to the Public Security Bureau right away. In China, delay isn't just risky. It can mean the gap between limiting the damage and losing control of your company's legal identity.

Japan: A Government Reform That Culture Hasn't Fully Caught Up To

Japan's hanko and inkan culture runs deep. The practice goes back over a thousand years. It also led to one of the biggest changes in Asia — one that's still not done. In 2020, then-Minister for Administrative Reform Taro Kono announced a plan. He wanted to remove hanko rules from government steps entirely. He famously said the government should "kill the hanko." Out of roughly 14,900 government steps that once required a hanko, over 99% no longer do today. Only around 80 still do. Most of these involve the registered personal seal (jitsuin), a bank-registered seal, or an official seal certificate. These stay key to big deals like buying property and registering companies.

Here's the twist worth knowing. The reform changed government forms, but not business or school habits. Over 90% of Japanese firms still use hanko every day. A Ministry of Education survey from late 2025 found that 91% of Japanese public schools still ask for a hanko stamp on papers. This is despite an official goal to end forced stamping. Japan's Act on the Use of Electronic Signatures (2000, amended since) gives a correctly signed e-signature the same legal standing as a hanko. E-seal tools are growing too. For now, "going digital cut mandatory use" is true on paper. In daily life, it's still a work in progress.

Rule of thumb: never use another person's registered seal, even if they say it's fine. Report a lost or stolen jitsuin to the local city office right away. Until you do, anyone who finds it can use it along with your seal certificate.

South Korea: Dojang Culture, Slowly Meeting Digital Signatures

South Korea's personal and corporate seals — dojang — carry weight much like Japan's hanko. This is true both in culture and daily use. They matter most in banking, property deals, and formal papers. E-signatures are now widely accepted for everyday business. But for the biggest deals — property, bank mandates, major company choices — the physical dojang is still the norm.

Rule of thumb: limit dojang access to approved staff only. Never leave a corporate dojang in a drawer that anyone in the office can reach. The same strict custody rules that apply to a Chinese company chop apply here too.

India: From Mandatory to Optional in a Single Amendment

Here's a detail worth getting right. The Companies Act 2013, as first passed, actually required Indian firms to put a common seal on certain papers. Share certificates and bills of exchange were among them. The Companies (Amendment) Act, 2015 changed this. It swapped "common seal" for "common seal, if any," everywhere in the Act. That made it fully optional. Since then, Indian firms can sign papers in three ways. They can use two directors' signatures, a director plus company secretary, or an accepted e-signature.

In practice, many Indian businesses still use a common seal anyway. It's a strong sign of trust for banks, foreign partners, and formal deals, even though the law no longer requires it. If a company's own Articles of Association still require a seal, that internal rule still applies — no matter what the national law now allows.

Rule of thumb: whatever your Articles say, tie every seal use to a real board vote. An unapproved seal mark is exactly the kind of thing that causes disputes years later.

Singapore: Abolished Cleanly, Kept Voluntarily

Singapore took the UK's approach and copied it closely. As of 31 March 2017, under the Companies (Amendment) Act 2017, companies and LLPs no longer need a common seal. This covers deeds, share certificates, or any other document that once required one. Two approved signers (or one director in front of a witness) is now enough. Many Singapore companies still keep a seal for ceremony, or because an overseas partner expects one. But by law, it's now fully optional — joining Australia, Hong Kong, and the UK, which have all made the same change.

Malaysia, Indonesia & Thailand: Law Loosening, Habit Holding Firm

Across much of Southeast Asia, the pattern is much the same. Legal rules for company seals and stamps have loosened. Signatures and e-signing are on the rise. But everyday habit hasn't caught up nearly as fast. In Malaysia, company seals remain common, even as more firms sign with just a signature. In Indonesia, company stamps (cap perusahaan) still play a big role in licensing and daily paperwork. In Thailand, government offices and banks often still ask for a company stamp alongside a signature. This holds even where the law no longer strictly demands it. If you're doing business in any of these markets, the safest move is simple: ask the specific partner or office directly, rather than guess.

Vietnam: From State-Controlled to Fully Self-Managed

Vietnam's change here is one of the clearest cases of loosened rules in the region. Under the 2005 Enterprise Law, a firm's seal had to be physically listed with the police. The police then issued a seal specimen certificate. The 2014 Enterprise Law eased this to a simple notice to the business registration office. Then the 2020 Enterprise Law (in effect from January 1, 2021) dropped even that step. Firms no longer need to register or tell anyone about their seal at all. They're free to pick their seal's shape, number, and content on their own, through their own charter.

Just as important, the 2020 law now formally accepts a proper digital signature as a valid form of "seal." This puts a physical stamp and a real e-signature on equal legal footing for the first time. There's a trade-off, though. Seals are no longer publicly registered. This means the other side now has no central list to check a Vietnamese company's seal against. That makes it more vital than ever to check the signer's real authority directly.

The Middle East (West Asia): real Weight in Government and Trade

Across the Gulf, the company stamp remains a real part of doing business. Government dealings, customs checks, and trade paperwork usually expect one. Not having it can slow down a step that would otherwise move fast. For any Nigerian exporter working with Gulf partners or customs offices, showing up without a proper company stamp isn't just a style gap. It can slow down your real work.

Ethical Guidelines for Using Stamps and Seals Across Asia

• Keep strict custody controls — in seal-first countries like China, Japan, and South Korea, whoever holds the seal holds real control of the company. Treat it that way.
• Keep usage registers — record the date, purpose, and approving officer for every use, physical or digital.
• Never copy government seals — this is treated as a serious crime in almost every country covered here, not just a civil dispute.
• Replace lost or stolen seals right away. In countries with formal registration (China, Japan's jitsuin, South Korea), report the loss to the right authority the same day — not "when convenient."
• Set clear authority levels for digital and physical seals alike. An electronic chop or e-seal deserves the same access controls as the physical one, since several countries above now give both equal legal weight.

What This Means If You're a Nigerian Business Dealing With Asia

Build this one habit above all: if you're dealing with a Chinese, Japanese, or South Korean partner, never assume a document is "correctly signed" just because it has a signature on it. Ask directly whether their seal or chop is needed. If it is, ask whether the person who applied it was actually approved to do so — the seal itself won't tell you that. On the other hand, don't assume every Asian partner needs a seal at all. Singapore, and increasingly India, have moved firmly toward signature-based signing.

For your own side of these deals, it helps to have two things ready: a precision-made physical seal, and a well-made digital stamp. Then you're never caught off guard, no matter which side your partner falls on. That's exactly the dual-track service MALLAMIBRO KONCEPTS LTD builds for Nigerian firms trading abroad. We make embossing seals to exact specification for partners who still expect one. We also make sharp digital stamps and electronic seals (PNG, JPEG and PDF) for the growing number who don't.
