Mr Quyen - Santiago. Posted 13/11/2026
A UK builders' merchant or roofing distributor can import Santiago ASA/PVC roof tile sheets from Vietnam by the 40 ft container, about 5,000 m with colours and accessories mixed, made in about 5 days. Goods under HS 3925.90.00 can enter under CPTPP, which the UK joined in December 2024, or the UK–Vietnam FTA; your customs broker picks the better route and confirms the rate. Each container ships with proof of origin and a quality certificate.

What does a UK merchant actually stock?
UK searches for plastic roof tiles centre on outbuildings: garden rooms, summerhouses, log cabins, sheds, porches, carports and stables. Customers want a tiled look that matches the house without the weight of concrete or clay. Santiago's product for that is a Spanish-style tile sheet, 1.05 m wide, 0.96 m cover width, with a tile row every 219 mm and cut to length in those steps. At 2.5 mm it weighs about 5.4 kg per m² of roof.
For the merchant, the point is that one line covers many sizes of building. You choose a handful of lengths and colours, and add the accessories that finish the roof: ridge cap, hip ridge, three-way and four-way pieces, ridge terminal, eave sealing tile, vertical wall flashing and ASA screw caps, all in the same colours.
CPTPP or the UK–Vietnam FTA?
The UK joined CPTPP in December 2024, and the UK–Vietnam FTA (UKVFTA) also applies to goods made in Vietnam. Either route can give a lower or zero rate for HS 3925.90.00, and your customs broker picks the better one for your shipment and confirms the rate. You can also ask HMRC for an advance ruling on classification and origin before the first order.
Felixstowe or Southampton?
Choose Felixstowe or Southampton, whichever is closer to your warehouse. Shipping terms to your port are agreed in Santiago's quotation, which is given per order in writing. Production takes about 5 days after the order is confirmed, and the video below shows how Santiago loads tile sheets into an export container.

How should a first UK container be planned?
Think in roof faces, not in sheets. Garden buildings in the UK are small, so short lengths move fastest. The plan below is one way to split about 5,000 m; Santiago confirms the final load plan with the quotation.
| Length (tile steps) | Sheet length | Fits | Example share |
|---|---|---|---|
| 9 steps | 1.971 m | Faces of small sheds and summerhouses | about 1,500 m |
| 11 steps | 2.409 m | Garden rooms around 3 × 4 m | about 1,500 m |
| 14 steps | 3.066 m | Log cabins and wider garden rooms | about 1,200 m |
| 17 steps | 3.723 m | Single-slope roofs, carports | about 800 m |
| Accessories | Ridge cap, terminals, eave sealing tile, flashing, ASA caps | Every roof | listed line by line |
Split each length across the colours your customers ask for. The five standard colours are dark grey, red, chocolate, blue and orange, and green, white and purple are made to order. Corrugated ASA/PVC sheet can share the container if you also sell to farms or industrial buyers.
Which documents arrive with each container?
| Document | What it shows |
|---|---|
| Proof of origin | Goods made in Vietnam, for the CPTPP or UKVFTA route your broker chooses |
| Quality certificate (CQ) | Issued for every lot |
| ISO 9001:2015 certificate ICI-23087.D | The factory's quality system |
| Quatest test results | Test results for the sheet from Quatest |
| Invoice and packing list | HS code 3925.90.00, lengths, colours and accessories line by line |

What should you check on the samples?
Samples are free; the buyer pays the courier. Before you commit to a container, check these on the bench and outside:
- Cut a sample and look at the edge: four co-extruded layers with no glue line, ASA on top, milky-white PVC underneath
- Measure the thickness (2.5 or 3.0 mm) and the 1.05 m width
- Measure the tile step: 219 mm from one row to the next
- Look at each colour outdoors in daylight next to brick, render and painted timber
- Fit a ridge cap and a screw cap to check colour match and fit
What do UK customers ask, and what can you answer?
Colour first. The ASA top layer showed no colour change after 2,000 hours of artificial UV, the colour is rated for 30 years, and real roofs last 25 – 30 years. The warranty is 10 years for 2.5 mm and thicker, installed as Santiago recommends.
Noise second, especially for garden offices. In Santiago's tests rain noise on the sheet is about 80% lower than on metal sheet, and the space under it is 6 – 8 °C cooler than under bare metal sheet. Weight third: about 5.4 kg per m² at 2.5 mm, light enough to carry and fix by hand.
Then the questions you should not answer with a yes. Santiago has no certification under UK Building Regulations and publishes no fire, wind or snow rating. Tell customers to check with their local planning office and building control, and let their builder decide. Installation needs a pitch of 20 – 45% (about 11° to 24°), purlins less than 700 mm apart and screws through the top of the wave; the details are in our garden room roof guide.

How is a container of tile sheets loaded for export?
Mr Quyen explains in English how Santiago loads orange tile sheets for export. The sheets slide down a ramp from the stack into the container, and workers in Santiago uniforms stack them inside.

Both clips below come from Santiago's own YouTube channel and were filmed at the factory in Vietnam or on Santiago roofs.
How are sheets tested and strapped before they leave the factory?
The short opens with a red ridge piece under a truck tyre, then Mr Quyen holds a gas torch to blue and red tile sheets on the factory yard and ends on strapped stacks of sheets ready to ship. A flame test is a demonstration, not a fire rating.

CPTPP: lower import duty on roofing sheets made in Vietnam
Vietnam is one of the 12 member countries of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), together with Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and the United Kingdom. Santiago ASA/PVC roofing sheets and accessories are made in Vietnam (HS 3925.90.00), so buyers in these countries can claim the CPTPP preference when they import them.
- Lower or zero import duty. Each member cuts its tariffs on goods of Vietnamese origin under its own CPTPP schedule, and many tariff lines are already at 0%. Your customs broker confirms the rate that applies to HS 3925.90.00 on the day of import.
- Proof of origin with every container. Santiago prepares the CPTPP origin documents for each shipment, so the importer can claim the preferential rate at clearance.
- Advance rulings. Under CPTPP, an importer can ask its customs authority for a written ruling on tariff classification and origin before the goods ship, so the duty is known before the order is confirmed.
- Faster, more predictable clearance. CPTPP members commit to publish their customs rules and, where possible, to release goods within 48 hours of arrival.
- The same preference on every repeat order. As long as the sheets are made in Vietnam and the origin documents are in order, each new container qualifies again.
Duty rates and paperwork change by country and over time: check the current rate and the proof-of-origin form with your customs broker before you order.
