Cross-Border Must-Know: Complete Guide to K1 & K2 Customs Forms for Malaysia-Singapore Shipments

Cross-Border Must-Know: Complete Guide to K1 & K2 Customs Forms for Malaysia-Singapore Shipments

If you’re handling cross-border deliveries between Malaysia and Singapore, you will definitely come across two critical documents: K1 and K2 forms.

These are not random papers — they are mandatory customs documents required by Malaysian Customs. Fill them in correctly, and your cargo passes smoothly. Make a mistake, and you’ll be spending extra time and money resolving issues with customs!


K1 = 进口申报表 Import Declaration Form  用途:当货物进口到马来西亚时使用(无论是从新加坡还是其他国家)。 谁用:进口商、货运代理、报关行。 流程: 找好运输公司,提供货物资料:invoice,packing list,发货人,收件人资料给负责人 运输公司负责人拿好资料会帮忙申请 Permit 还有K1 form的准备和填写(约1天的时间) 货到马来西亚港口/关口  海关审核  缴税(若需) 一般上运输公司会通过HS code告诉你需不需要 放行 → 货物送到你手上  重点信息: 货物种类、数量、价值、HS Code(海关编码)都要写正确,写清楚! 有遗漏或写错,要及时修正,如果到海关那边才发现错误,就会有被扣留的可能,全部流程和文件需要重新申请  简单来说,K1 就是马来西亚关卡会问你:“你带了什么进来马来西亚?值多少钱?从哪来的?” 只要文件准备齐全,都是正常合法物品就会让你进了
What is the K1 Form?

K1 = Import Declaration Form

📌 Purpose: Required when goods are imported into Malaysia (from Singapore or any other country).
📌 Used by: Importers, freight forwarders, customs brokers.

Process:

  1. Appoint a freight forwarder / logistics provider.

  2. Provide shipment details: invoice, packing list, shipper & consignee info.

  3. Freight forwarder prepares the import permit and K1 form (processing takes ~1 day).

  4. Goods arrive at Malaysian port / checkpoint.

  5. Customs review & inspection.

  6. Duty payment (if applicable) – your logistics provider will check via HS code.

  7. Cargo released → delivered to you.

Key Details to Include:

  • Cargo type, quantity, declared value, and correct HS Code (customs tariff code).

  • Errors or missing details may cause shipment holds — requiring re-submission and delays.

👉 Think of the K1 form as Malaysia Customs asking:
“What are you bringing into Malaysia? From where? What’s the value?”
As long as everything is accurate and compliant, clearance is smooth.


什么是 K2 表格?  K2 = 出口申报表 Export Declaration Form  用途:当货物从马来西亚出口到其他国家(比如新加坡)时使用。 谁用:出口商、货运代理、报关行。 流程: 找好运输公司,提供货物资料:invoice,packing list,发货人,收件人资料给负责人 运输公司负责人拿好资料会帮忙申请 Permit 还有K2 form的准备和填写(约1天的时间) 货到马来西亚关口  海关审核  缴税(若需) 一般上运输公司会通过HS code告诉你需不需要 放行 → 货物送到你手上  重点信息: 在马来西亚出口去新加坡,要写明清楚出口目的地的详细地址、货物种类、数量、价值、HS Code,都要清楚详细。  K2 就是马来西亚关卡会问你:“你要把什么带离开马来西亚?要去哪?值多少钱?” 等等,只要清楚写明了就会放你出境了。
What is the K2 Form?

K2 = Export Declaration Form

📌 Purpose: Required when goods are exported from Malaysia (e.g., to Singapore or other countries).
📌 Used by: Exporters, freight forwarders, customs brokers.

Process:

  1. Appoint a freight forwarder / logistics provider.

  2. Provide shipment details: invoice, packing list, shipper & consignee info.

  3. Freight forwarder prepares the export permit and K2 form (processing takes ~1 day).

  4. Goods arrive at Malaysian checkpoint.

  5. Customs review & inspection.

  6. Duty payment (if applicable, though most exports have no tax except for restricted goods).

  7. Cargo released → delivered to consignee.

Key Details to Include:

  • Export destination address

  • Cargo type, quantity, declared value, and HS Code

👉 Think of the K2 form as Malaysia Customs asking:
“What are you taking out of Malaysia? Where is it going? What’s the value?”


K1 vs K2 的区别
K1 vs K2 – Key Differences

Aspect K1 (Import) K2 (Export)
Direction Foreign → Malaysia Malaysia → Other countries
Use Case Singapore → Malaysia / Overseas → Malaysia Malaysia → Singapore / Malaysia → Overseas
Party Involved Malaysian Importer Malaysian Exporter
Taxation May involve import duties & SST Usually no export tax (except special goods)

K 1 和 K2 Form里面这些数字很重要?  1. Declaration No.(报关单号)     海关系统的身份证,唯一标识一票货。    例子:J25-2-12345678/25       J25 = 海关关口代码,不同关口有不同的代号      2 = 表格类型(这里是 K2)如果是“1”就代表是K1     12345678 = 申报流水号      /25 = 年份(2025)   2. HS Code(Harmonized System Code)  全球统一的商品编码系统,用于分类和决定关税税率。 为什么重要?因为报错可能导致税率变高,甚至被扣货。 同时,任何物品,不同形态,都会有不同的税率 例如:咖啡 咖啡又分为很多种形态,比如咖啡豆,纯咖啡粉,3in1 咖啡粉,咖啡浓缩液等等 这些物品的HS code其实是完全不一样的,并不能因为是 “咖啡” 而统一用同一个code!
Why Are K1 & K2 Numbers Important?

1. Declaration No. (Customs Declaration Number)

This is like an ID number for each customs entry. Example:
J25-2-12345678/25

  • J25 = Customs checkpoint code

  • 2 = Form type (K2). If “1” → it’s K1

  • 12345678 = Serial number

  • /25 = Year (2025)


2. HS Code (Harmonized System Code)

The global standardized system to classify goods and determine tax rates.

Why it matters:

  • Wrong HS code = higher tax OR cargo detention

  • Different product forms = different codes & tax rates

Example: Coffee

  • Coffee beans ≠ pure coffee powder ≠ 3-in-1 instant coffee ≠ coffee concentrate
    Each has a different HS code and different tax rate.

🔎 Useful HS Code Tools:

⚠️ Note: Singapore Customs updates tariff rates weekly. Always double-check current tax rates.


3. Cargo Quantity & Value

Every item must be declared clearly:

  • How many boxes?

  • How many pieces per box?

  • Value per item & total value?

The more accurate, the smoother the clearance process.
