The container has arrived at Karachi Port. That’s when a lot of Pakistani importers discover how
much they didn’t know about customs clearance and start paying for it. Demurrage bills at
$80 a day. Red channel examinations that stretch to 12 working days. Valuation disputes that
add 30% to the duty assessment. HS code penalties on goods that were honestly declared but
incorrectly classified.
This guide covers the actual clearance process in 2026, including the WeBOC-to-PSW
transition that most competitor content ignores. It builds on our complete guide to importing from
China to Pakistan and our FCL vs LCL shipping guide.
WeBOC vs PSW What Is Actually Live in 2026
Most customs clearance guides you’ll find still say “file your GD on WeBOC.” That’s partially
accurate and increasingly incomplete
WeBOC (Web-Based One Customs) has been Pakistan Customs’ electronic clearance system since 2011. It handles Goods Declarations, channel assignment, duty assessment, and release orders. It remains operational.
PSW (Pakistan Single Window) is the government’s broader trade facilitation platform — a
unified portal designed to integrate Customs (FBR), SBP, Ministry of Commerce, DRAP, PQS,
and other regulatory bodies into one submission point. PSW launched in phases from 2021
onward and is the active interface as of mid-2026.
The practical reality right now: GD filing happens through PSW’s customs module, which sits on
top of the existing WeBOC risk engine. Clearing agents who worked entirely in WeBOC now
work in PSW — but the underlying channel assignment logic, duty assessment rules, and
penalty mechanisms are still WeBOC-based processes running under a new interface.
What PSW changes for importers: your EIF cross-reference, SBP-linked filings, and regulatory
approvals are now processed within the same portal as your GD. The single-window concept
reduces the number of separate agency contacts your clearing agent manages in theory.
Integration is still maturing in some ministries, and experienced agents maintain familiarity with
both systems.
When evaluating a clearing agent in 2026: ask whether they’re registered and active on PSW. If they only know WeBOC; their workflow is a version behind.
Documents You Need and the China-Side Ones Importers Forget
The standard document list is well-known: Commercial Invoice, Packing List, Bill of Lading (or
Airway Bill for air freight). Your clearing agent will tell you this on day one.
What doesn’t get enough attention is that three of the most common clearance failures in
Pakistan originate from errors made in China, before the container was sealed.
Commercial Invoice: Must show unit price, quantity, product description, HS code (Chinese
national), total FOB or CIF value, and full seller/buyer details. The declared value on this invoice
will be cross-checked against your EIF payment record by the appraiser. If they diverge, it
triggers scrutiny.
Packing List: Must accurately reflect carton count, gross weight per carton, net weight, and
outer dimensions. CFS operators and customs examiners weigh and measure. If your declared
500 cartons at 8 kg each arrive at 11 kg each, your GD is inconsistent before the examiner
touches a single box.
PFTA Certificate of Origin (Form P): Issued in China before departure by CCPIT or the local
customs bureau. This is the document that unlocks reduced or zero duty under the
China-Pakistan Free Trade Agreement. It must specifically reference the CPFTA a general Certificate of Origin does not qualify. If it isn’t obtained before the vessel sails, you cannot claim CPFTA relief at the time of GD filing.
HS code consistency across both declarations: The HS code on your Pakistani GD and the
code on your Chinese supplier’s export declaration should align. When they don’t — even for
legitimate classification reasons customs flags it for review.

The pattern we see consistently from our Yiwu operations: Pakistan-side clearance delays trace
back to documentation that was wrong or incomplete when the container left China. Fixing it
after arrival is slower, more expensive, and sometimes not possible at all.
