Guangzhou–Panyu corridor · EU & US import compliance

The evidence your Panyu suppliers can't produce is your liability, not theirs.

We read the rules now landing on one manufacturing corridor — EU diamond-origin due diligence, UFLPA, CBAM, EU machinery and battery law — match them against the supplier list you already have, and tell you which evidence to demand this week.

Decision briefIllustrative
Exposure: high

Precious-metal jewellery finisher

Panyu, Guangzhou · Tier 2 to your EU program

Why now
Natural polished diamonds of 0.5 ct or more have required a due diligence statement on origin at EU import since 1 January 2026 — the final phase of the diamond measures under Article 3p of Regulation 833/2014.
On file
Kimberley Process certificate, final stage only. No listing of countries of mining origin.
The gap
Mixed-origin polished stock routed through a third country. A final-stage KP certificate does not evidence that no stone in the parcel originated in Russia.
Next action
Request a mining-origin declaration plus a due diligence statement reference per consignment, before the next shipment is booked.
Basis
Your bill of materials, your declared EU destinations, and the published rule text. Inference — not an assertion about any supplier's conduct.

01 / The gap

A rule lands. Your supplier can't answer it. You find out at the port.

Every compliance failure we have seen follows the same four beats. Three of them are outside your control. One of them is not — and it is the only one that is still cheap to fix.

01

The rule lands in Brussels or Washington

Published in the Official Journal or the Federal Register. Effective on a date you cannot negotiate. Written for operators and importers — which, legally, is you.

02

Your Panyu supplier cannot produce the evidence

Not evasiveness. The documents do not exist upstream, the data sits in six systems with six different units, or releasing it runs into Chinese law on data and cross-border investigation.

03

The liability stops with the importer

Under UFLPA the burden is a rebuttable presumption: you prove the goods are clean. Under the diamond measures you supply the statement. Everywhere, the file that gets examined is yours.

04

You find out when the container stops

Detention, re-export, cash tied up, a customer who now remembers your name for the wrong reason. By then the only question is what your file can prove.

02 / Coverage

One corridor. The rules that actually bite in it.

We do not cover the world. We cover the Guangzhou–Panyu corridor and the four instruments that are currently creating evidence gaps in it.

Instruments tracked

EU diamond originIn force · 01 Jan 2026

Due diligence statement on origin required for natural polished diamonds ≥ 0.5 ct. Art. 3p, Reg. 833/2014; 12th, 14th and 16th sanctions packages. Direct ban since 01 Jan 2024; third-country processing in scope since 01 Sep 2024.

UFLPA187 entities · 03 Aug 2026

43 entities added in a single notice — the largest expansion since 2022, and nearly half outside Xinjiang. Origin-based screening no longer works; ownership and trade routing is what remains.

EU machinery lawApplies 20 Jan 2027

Regulation (EU) 2023/1230 replaces the Machinery Directive with no sell-off period — stage machinery and amusement equipment built to the old regime cannot be cleared after the date.

CBAMIn force · 01 Jan 2026

Aluminium and steel content in exported assemblies. Default values are uplifted by 10% in 2026 and 20% in 2027 — the calculation, not the tax, is where suppliers fail first.

03 / How it works

Signals alone are noise. Signals constrained by your actual supply chain are a worklist.

The value is not in finding the rule. Anyone can find the rule. The value is knowing which of your lines it touches, and what to ask for on Monday morning.

Stage 01

Signals

Official journals, agency notices, customs datasets, sanctions and enforcement lists, court filings, trade records. Continuously collected, de-duplicated, versioned.

Every signal keeps its source link and timestamp.

Stage 02

Your supply chain

Supplier list, materials, declared destinations, tiers. Built once, inside your own environment. No ERP or MES integration required.

Built once — and reusable later for EU DPP and US CMMC.

Stage 03

Constraint match

A signal only survives if it hits a material you buy, a tier you actually reach, and a market you actually ship to. Everything else is dropped.

This is where the noise dies.

Stage 04

Evidence queue

Each week: the open items, the exact document to request, the deadline that makes it urgent, and the reasoning a CFO or a customs broker will accept on the first read.

Every item settles into a dated record.

04 / What you actually receive

One page per item. Source, gap, request, deadline.

No dashboards to learn, no scores to interpret. A short weekly list of things that have to be asked for, with the reasoning attached so it can be forwarded without rewriting.

Weekly queue — extractIllustrative
Item 1
Jewellery finisher · Panyu — natural polished stones ≥ 0.5 ct. Request mining-origin declaration and DDS reference per consignment. Open since 1 Jan 2026.
Item 2
Luminaire assembler · Panyu — stage machinery destined for an EU venue. Ask which conformity route the new Machinery Regulation assessment will use. Hard date 20 Jan 2027.
Item 3
Cabinet maker · Panyu — aluminium frame content in redemption machines. Confirm whether any extrusion is smelted with grid power; this drives the CBAM default-value uplift.
Item 4
Knitted textile mill · Guangzhou — cotton content traceable to province level. UFLPA screening by origin will not clear this; ownership chain required.
Record
Each item carries: date raised, document requested, date received, source citation. The record is the deliverable — it is what you hand over when you are asked to prove what you did and when.

05 / What it isn't

What we will not do — and why we tell you first.

A compliance product that over-claims is worse than no product. These limits are architectural, not disclaimers bolted on at the end.

Positioning

We never assert that a named supplier has broken a law.

Every output describes your exposure and the evidence gap in your file. We do not publish or sell findings about third parties' conduct. Language in the product is deliberately narrow: exposure indicator, evidence gap, unverified claim.

Scope

We are not your legal counsel.

We produce an evidence worklist and a dated record. Classification, liability and filing decisions stay with your counsel and your customs broker. The rule text is always linked so it can be checked independently.

Architecture

We do not request documents from Chinese entities on your behalf.

Chinese authorities have designated certain cross-border regulatory requests as improper extraterritorial jurisdiction. We produce the request list; who sends it, and on what legal basis, is your decision. Suppliers may upload voluntarily or not at all.

Sourcing

We do not buy trade data to guess your suppliers' customers.

Public sources only, cited and timestamped. That sets a ceiling on certainty — and we label it. Every inference is marked as an inference, with the evidence it rests on.

06 / Who this is for

Built for the party that carries the file.

Trading houses & sourcing officesHong Kong · Singapore · Taipei

You are the importer of record for goods you did not make, from suppliers you did not choose. You carry the full filing obligation and you have no compliance team. This is the customer we built it for first.

Mid-size EU and US importersOwn-label jewellery, pro AV, entertainment hardware, apparel

Large enough to be inspected, too small to run a due-diligence platform. You need to answer a customer questionnaire or a customs request without hiring a team to do it.
